In his office at No. 26 Hospital of Yuetan South Street, he explained to reporters in detail the operation of the industry in the first half of the year and predicted the trend in the second half of the year. “Although the year-on-year increase in production and sales, profits will gradually decline from the mid-year high, However, the annual increase is expected to reach 15%."
Operational articles: strong growth in production and sales exceeded expectations “According to the statistical data since the beginning of this century, the increase in production and sales of the instrumentation industry by around 30% year-on-year can be considered as a historically high area, and the data for May and June of this year have entered the region and a single month. The value of production and sales has reached a record high,†said Yan Jia, a reporter who listed several figures: In June, the production and sales value was 48.8 billion yuan and 47.9 billion yuan, which exceeded the historical highs of 44.1 billion yuan and 44.3 billion yuan in December 2009. .
Regarding the strong growth in production and sales in the first half of the year beyond the forecast at the beginning of the year, he summed up the main reasons in three sentences: strong domestic demand, rising exports, and a very low base in the previous year.
It is worth noting that the growth trend of various sub-sectors is different, with strong demand for instruments and meters adapted to energy saving and environmental protection, people's livelihood, and economic restructuring. For example, environmental monitoring equipment has maintained an increase of more than 40% for four consecutive years, and reached the first half of this year. 70.31%; With the increase of automobile output, the increase of automotive instrumentation reached 41.37%. Although the industrial automatic control system devices were affected by the decline in demand from metallurgical and thermal power industries, due to energy saving, emission reduction, technological transformation, and emerging industry demand Rising, these products have increased by more than 30% compared with experimental analysis instruments related to improving the level of scientific research and production; surveying and measuring instruments, supply instruments, and timing instruments, etc., which are greatly affected by infrastructure, real estate, and exports, have seen relatively low growth. .
"This precisely reflects the direction of the country's economic restructuring and the impact of its policies." Yan Jiacheng analyzed.
The sharp rise in profit margins to a high level is accompanied by rapid growth in production and sales, which is a sharp rise in industry profits and a significant increase in imports and exports.
According to Yan Jiacheng, the accumulative profits of the industry from January to May increased by 74.37% year-on-year, and the main-account profit rate reached 7.87%, which is close to the historic high level of 2007, and “more than 1 percentage point higher than the main industry's profit marginâ€.
The profit recovery of the industry also showed three characteristics: the year-on-year growth rate of the industry with low or negative base growth was high. For example, the growth rate of optical instruments and analytical instruments was as high as 128% and 138% respectively; the foreign-funded enterprises with negative profit growth in the same period last year The growth rate of state-owned holding companies was high, at 108% and 89%, respectively; in addition, some companies with technological progress, structural adjustments, and advancement of modern production management enjoyed rapid growth in profits, such as Zhejiang Zhongcheng and Zhengtai Instrument. “These two companies have paid high-paying foreign experts to implement modern production management, reduce inventory, and increase capital utilization.â€
It is understood that in the first half of the year, the year-on-year growth of imports and exports in the instrumentation industry was above 40%, and the import and export volume continued to rise in a single month, but the year-on-year increase in imports had turned a declining trend in June. "This indicates that the increase in imports and exports will slow down." .
Yan Jiacheng told reporters that large quantities of imported products with high growth rates are products with strong demand but large domestic industry gaps, such as the import of program logic controllers (PLC) amounting to US$427 million, an increase of 96%; imports of semiconductor and component testing equipment 4.3 Billion U.S. dollars, an increase of 170%. Exports of large amounts and high growth rates are industrial automation systems and devices. In the first half of the year, exports amounted to 1.427 billion U.S. dollars, an increase of 49.4%. “This is a resumption of growth in the production of 'funded enterprises' and Chinese investment. Enterprise's self-produced export competitiveness and comprehensive achievements in undertaking foreign OEM orders."
In the first interview with the profitability of foreign-funded enterprises, Yan Jiacheng also focused on the situation of foreign-funded enterprises.
The foreign-funded enterprises account for a relatively large proportion in the instrumentation industry. In the high-speed development period at the end of the “Tenth Five-year Plan†and the “Eleventh Five-Year Plan†period, its production and sales accounted for 45% of the entire industry and its profits exceeded 50%. Affected by the financial crisis and other factors, its production and sales ratio fell to 32.6% last year, and its profit ratio fell to 37.6%. In the first half of this year, foreign-funded enterprises came out of the bottom, with a production-to-sales ratio of 31.5%. However, from January to May, their profit growth was as high as 107.8%, accounting for 41.6% of the total.
“Compared with domestic companies, the profits of foreign-funded enterprises accounted for 10% higher than the proportion of comparative production and sales, and the main-account profit rate reached 10%, which was much higher than that of private and state-owned enterprises. This reflects the fact that Exports accounted for a large proportion (43.5% of outbound/sales ratios). Production and sales did not pick up quickly, but they had the characteristics and advantages of high technology and management level and strong innovation capability."
Prediction: Production and sales growth from year-on-year drop from the high point For the second half of the year, Ju Jiacheng judged that due to the increase in uncertainty in the chain, the year-on-year increase in production and sales will fall from the high point of the year, but it will not drop substantially.
Based on the cumulative year-on-year growth rate in the second quarter and the monthly production and sales value that have entered historically high levels, as well as the country’s efforts to strengthen economic restructuring, “the year-on-year decline in the year-on-year growth in the production and sales of the industry can be determined, but due to the decline in impact and the As the factors of change increase, the uncertainty of the trend will increase."
In this regard, he further explained that this uncertainty first includes the impact of economic restructuring on the demand for instrumentation. For example, measures such as suppression of “double heights†and overcapacity industries and excessive increases in house prices lead to industrial automation control devices, The traditional demand for on-site meters, supply meters, and surveying and mapping instruments has dropped. "The degree of decline is still difficult to determine."
Second, it includes the industry's adaptability to economic restructuring. China's industrial sector is facing an upsurge of corporate technological transformation driven by the implementation of energy-saving emission reductions and enhancement of independent innovation capabilities. The resulting large demand for measurement and control equipment will continue in the second half of the year. At the same time, the demand for monitoring and control equipment in emerging industries such as new energy has been or is being formed, but most of this type of equipment is still dependent on imports. Although some companies have made progress and breakthroughs, their capabilities and adaptability are yet to be tested.
In addition, it also includes the status of the international market and exchange reform efforts. Yan Jiacheng told reporters that in addition to affecting imports and exports, some foreign-funded enterprises also use foreign exchange reform to further reduce price competition. While maintaining the advantage of the high-end market, they also try to expand the market share in the mid-range and even low-end markets.
"Although the above uncertainties will cause the instrument and meter industry to slow down in the second half of the year, there is little chance of a sharp and sharp drop," Yan Jiacheng said with certainty.
The profit growth rate is still higher than the increase in sales. “Although the base number, the year-on-year growth rate of the industry's profits will continue to fall, but the industry's profit growth can still maintain a good state, the average monthly profit value will continue to rise, the annual profit growth It will still be higher than the increase in production and sales, and the main income margin will exceed 7.5%.â€
For the above judgment, Yan Jiacheng gave three reasons:
First of all, although the demand will be levelled off in the second half of the year, the effectiveness of technological progress, economies of scale, and enhanced management will continue. He gave an example: In 2008 and 2009, the output value of new products increased by 11.5% and 7.5% year-on-year, respectively. In the first half of this year, the increase has risen to 43.46%, and the proportion of new products has reached 16.04%; from January to May this year, the industry The increase in production and sales reached 30%, but the increase in product inventory was only 7.31%. The balance of liquidity, accounts receivable, liabilities, management fees, and financial expenses were all lower than the increase in sales.
"In the second half of the year, the above data will turn flat, but it will not rise quickly and lead to a substantial drop in profits."
Second, foreign-funded enterprises have already bottomed out. "Three capitals" is a large profit in the instrumentation industry. Although its profit growth in 2008 was -2.68% year-on-year, the first negative profit growth since the reform and opening up took place, and the growth rate in 2009 was only 1.3%, showing a stagnant state. However, in the first half of this year, its growth rate has soared. And more than 100%.
Yan Jiacheng told reporters that multinational corporations stated that the subsidiaries in China are the best companies in the world, and some companies expect that the rise in China’s business is an important factor in the company’s failure to “deficit†its operations and maintain the “black printâ€. Therefore, "unless the international market deteriorates sharply in the second half of the year, the operating conditions of foreign-funded enterprises will remain unchanged compared with the previous year."
In addition, there is little pressure to increase costs. There was a rise in raw materials and components at the beginning of the year, but it has slowed down in the middle of the year, and it is expected that there will be little chance for another rise in the second half.
The year-on-year increase of about 15% was affected by the previous year's base number and seasonal factors. Both the year-on-year growth in production and sales and the single-month value will both decline significantly. The key to the chain's trend depends on the operating conditions in September.
Yan Jiacheng told reporters that according to historical statistical analysis, if the data in September is higher than the high point in the middle of the year, then the upward trend in the fourth quarter could be expected. The annual growth rate will reach more than 25%; if the data in September is close to Mid-year highs, then the monthly rate in the fourth quarter will fluctuate upwards. The annual increase will be above 15% or 20%. If the September data is much smaller than the mid-year high, there will be a weaker chain growth in the four seasons, and the monthly sales will be lower than the end of the year. In the middle of the year, the growth rate will also fall below 13% in the weak state of the middle-year high, and the impact of its trend will be delayed until the first half of next year.
The high operating data in the first half of the year has laid a good foundation for the whole year. According to the current operating conditions of the majority of key enterprises, although the demand is slowing down, but the rate of decline is not large, “expects the year-on-year growth in production and sales, profits, although gradually decreased, but all The annual production and sales growth will be around 15%, and the profit growth will be higher than 15%." Yan Jiacheng said.
What is Precision CNC Milling
In general, computer numerical control milling machine (CNC) machining is a deductive manufacturing technique that programs 3-axis linkage, complex to 5-axis linkage, drives milling cutters to remove layers from solid blocks called blanks to produce finished parts. CNC milling is one of the main types of CNC Machining, which uses cutting tools that rotate at a speed of several thousand to tens of thousands of revolutions per minute (RPM) to precisely remove materials to obtain parts with complex surfaces. In addition to milling, CNC machining is also equipped with drills, boring tools, thread cutters and other tools to complete different part features at once. CNC machining produces parts based on a computer-aided design (CAD) model that is sent to a CNC machine through computer-aided manufacturing (CAM) software.
CNC Machining centers developed from CNC milling machines. The biggest difference compare to CNC milling machines is that the machining center has the ability to automatically exchange machining tools, by installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed through the automatic tool changing device in a single clamping device to achieve a variety of machining functions.

CNC milling accuracy
CNC milling centers and high-Precision Machining centers. Ordinary machining center, resolution of 1μm, maximum feed speed of 15 ~ 25m / min, positioning accuracy of about 0μm. High-precision machining center, resolution of 0.1μm, maximum feed speed of 15 ~ 100m / min, positioning accuracy of about 2μm. Between 2 and 10 μm, with a ± 5 μm more, can be called precision grade. FCE equipped with different grade and different size CNC milling center. Take in to account into both economic and quality in parallel.
CNC Finishing surface treatment
Post-processing is the final step in the CNC machining process. In a quick guide, we offer a lot of surface treatments to complete your final parts and get them to meet strict specific requirements. It should be noted that in CNC machining, post-processing is in optional, as the quality of the machined parts is already very high.
Anodized
The anodizing process allows the part to obtain excellent corrosion resistance, increasing the hardness and wear resistance of the surface. Anodizing is also the most common pre-painting treatment, which can help the painted surface to obtain good adhesion. We typically apply two types of anodizing in our production: Type II, corrosion resistant; Type III is thicker, adding a layer of wear resistance. Both anodizing processes can achieve a variety of color effects.
Polishing
Grinding polish, it offers the fastest turnaround parts and does not require post-processing. The surface finish of the grinding part is equivalent to 125 um in Ra, and the requirements can be increased to 63, 32 or 16 um Ra. Minor tool marks may still be visible on the last part.
Powder coatings
Powder Coating is thermoplastic powder spraying directly on the processed part. The sprayed parts are then baked in an oven to form a durable, abrasion- and corrosion-resistant plastic coating. In the powder coating process, its color, brightness, surface roughness can be customized.
Shot blasting
Shot peening is the high-speed spraying of beads of different hardnesses and sizes onto the surface of the part. To get different textures and brightness of the surface. Since the surface has been hit by similar forging beads, the hardness and wear resistance of the surface have also been enhanced.
Design of CNC machining
CNC machining is a universal machining process, especially parts that can be cut and machined can be achieved through CNC, from simple shape shapes to complex curved structures. However, as with every manufacturing technique, CNC machining has some design limitations. We break them down as follows to ensure that your products are optimally designed to better fit the CNC machining process.
General Tolerance
When designing parts, the size of each part is different according to the application environment, working conditions, etc., and the requirements for the machining accuracy of the workpiece are also different. Although CNC machining can achieve very high machining accuracy, we should also be aware that demanding machining accuracy and accuracy (strict product tolerances) usually mean Longer production times and higher costs. If a specific tolerance is not specified in the product design, we recommend choosing at the following levels.

The highest precision of our equipment is 0.001, and the recommended most precise machining requirements do not exceed +/-0.005mm
Interior angle
All internal vertical edges of our products need to have rounded corners instead of right angles. This is because the tools used in CNC milling are cylindrical, which means they cannot produce inner right-angled edges. The fillet required by this process is called the inner corner fillet. When designing parts, the larger the inner corner fillet, the more efficient the production process. Because of the larger fillets, larger diameter milling cutters can be used to increase milling speed, and fewer swaps can be made to improve accuracy.
Undercut
Undercut cannot be machined with standard milling cutters, so the use of retract slots for parts should be avoided when designing CNC machined parts. In particular, for non-standard inner contour shapes, customized machining tools are required, which will greatly increase processing time and costs. Secondly, if undercut can not be avoided, due to the limited length of cnc tools, the undercut can not be too deep. If they are too deep or the location is difficult to reach, they will not be able to be produced because the CNC tool cannot reach the machining location.
Chamber wall thickness
CNC machining requires your part design to meet minimum wall thickness requirements. In general, it is recommended to choose the thickest possible and avoid very thin or characteristic walls. This is because CNC tools processing thin-walled parts will cause vibration deformation, which may cause interruptions or damage, and the size is out of specification. The standard minimum wall thickness for CNC machined metals is 0.030" (0.76 mm) and for plastics is 0.060" (1.5 mm).
Thread
When designing parts, it is useful to choose the largest possible thread size because smaller taps have a higher risk of breaking during production. If possible, avoid using deep hole threads as they lead to higher production costs, especially when custom tools are required.
Metal
In principle, materials with high hardness are easier to process because better processing accuracy can be obtained, but they are limited by the hardness of processing tools, so the hardness of the generally recommended parts is 8 ~ 60HRC, and for metal materials, the hardness is greater than stainless steel Followed by cast iron, followed by copper, and finally aluminum, while the processing of ceramics, plastics, etc. belongs to the processing of non-metallic materials. Fast production time.
Polymer
Although CNC can process thermoplastics, the material properties of polymers still have many difficulties for CNC processing. First, due to poor thermal conductivity, many thermoplastics melt or bend when in contact with CNC milling machines or drill bits. Secondly, the processing of plastics, because the hardness is low, the size accuracy caused by the knife during product clamping and processing is not high. For those parts that do not have special requirements for the strength and hardness of the metal, thermoplastics can provide a cheaper alternative.
Cost optimization of machined products
Simplify product design
Simplifying product design while taking into account functionality usually saves production time and reduces production costs. Because the manufacture of complex structures and surfaces often requires complex longer passes, more layering to obtain the same fine contour quality. This means higher production costs.
Reduce cutter changes
Using the same milling machine machining features, larger and same internal fillets, can reduce the number of tools used to reduce machining time. For example, if a workpiece needs a 10mm end face milling cutter to process some features, it also needs a spherical milling cutter to process a curved surface, and a 2mm milling cutter to process a fine groove, which will require repeated tool changes and reduce the machining efficiency
Proper material selection
The choice of raw material for machining can have a significant impact on production time and costs for CNC machining. If possible, choose a material with good processability, such as brass or aluminum. For those applications that do not require metal hardness and strength, CNC machining of engineering plastics like PMMA and ABS also helps to reduce costs because the material blank is cheaper, and the processing efficiency is higher.
Tolerance and wall thickness
Higher tolerances and thinner wall thicknesses also increase THE CORRESPONDING CNC machining costs, as it takes time to achieve higher precision cutting. If your product or component can accept a larger size range, choose a lower tolerance to reduce production time and costs. The same is true for wall thickness: a larger wall thickness margin should be chosen.
Choice of surface treatment
Surface treatment is often the final stage of the CNC machining process, which can also affect the cost of your entire project. Choosing less surface treatment for your part or product can lead to better time and cost efficiency. FCE can recommend to you how to optimize the surface treatment to balance the conflict between cost and quality according to your final needs.
