Automotive industry drive china injection mold manufacturing

Auto injection mold is still the most widely manufacturing in china, the field of industry development is rapid, every new car invest need thousands of pair of injection molds, auto makers has formed with the closely matching mould enterprise development, research and debugging technology, production of strategic alliance. Cars are increasingly high strength plate in order to reduce weight, also for some ultra high strength plate hot forming and the corresponding hot forming mould has naturally become the development trend.

Automotive Injection Molds to use plastic lighter will increase and the development of new materials, including all kinds of new plastic, modified plastic, metal, plastic, magnesium alloy, composite material, and so on, this requires a new forming technology, which also requires that have adapted to the new mold. According to network mold, China injection molds in the future in the market, the proportion of total plastic mold in the china will gradually increase, its development speed will be higher than other mold manufacturer.

“Injection mold to elegant, requires good appearance generous, internal defects, this would require careful, precision injection mold with high quality. At present, the refinement has a big gap, refinement is often ignored by some companies, the results fell short.” Company, I think that the injection mold fast and efficient production, the injection molding enterprises try to shorten the mold production cycle time, to plastic molding the user mould as soon as possible, on the other hand is more important, the user can you provide a injection mold to production products more quickly and efficiently. Such as more than a multi-cavity mould production, laminated mold, forming time and make good use of hot runner technology to shorten the use of multilayer composite technology, mould decoration technology, highlights non-mark injection molding technology, testing technology and process of composite technology and transfer technology and so on, at the same time stamping forming process intelligent also requires intelligent mold to adapt.

Precision injection molding in China

Precision injection molding and the common plastic molding difference

The characteristics of precision injection molding is: the size of the injection molded parts with high precision, small tolerance.

To achieve the requirements of precision injection conditions must be met:

(1) the mold material is better, rigid, cavity dimension precision and template between positioning accuracy is higher, lower surface roughness.

(2) to adopt precision plastic molding machine.

(3) to adopt precision molding process.

4) to choose suitable for precision injection molding process of the material. Commonly used precision molding materials have several: POM, POM = CF (carbon fiber), PNM = GF (glass fiber), PA \ FRPA66 (enhanced PA), PC, etc.

Precision injection process can ensure the size precision injection molding is the important way to control the shrinkage of injection molded parts, including: thermal contraction, disguised contraction of molded parts, orientation and compressed contraction and elastic recovery.

Common injection molding features are: precision is not high, the size of injection molded parts are typically can be assembled into standard, requirements for the appearance of the injection molded parts is relatively high, if necessary, may use the second processing (oil, for example) to improve the appearance of defects. Ordinary injection molding don’t need to use special precision injection molding machine, also do not need to specially designated materials, general common thermoplastics can be used to production. So ordinary injection molding technology is widely used in modern plastic industry.

Introduction to 3D printing technology

3D printing, i.e. a rapid prototyping technique, which is a digital document based on the model, the use of powdered metal or plastic materials may be bonded by way of the printed layer by layer technology to construct the object.
3D printing materials are usually printers using digital technology to achieve. Often in the mold manufacturing, industrial design and other fields are used to make the model, and then gradually for direct manufacturing of some products, there have been made using this technique to print parts. The technology in the jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, GIS, civil engineering, guns, and other fields have applied.

Everyday life of ordinary printer can print flat items used computer design, and the so-called ordinary printers and 3D printer works basically the same, but somewhat different printing materials, printing materials are ordinary printer ink and paper, while the 3D printer built with metal , ceramic, plastic, sand and other different “printed materials”, are real materials, the printer connected to the computer through computer control can be “printed material” layer laminated together, eventually became the blueprint on your computer kind. In layman’s terms, 3D printer can “print” of a 3D object in real devices, such as printing a robot toy car printing, printing of various models, and even food, etc.. The reason colloquially called “printer” is a reference to the technical principles of ordinary printer, because the process of layering and ink-jet printing process is very similar. The three-dimensional printing technology called 3D printing technology. [2]
There are many different 3D printing techniques. They differ in the way that the material is available, and to create build parts with different layers. [6] 3D printing materials are commonly used in fiberglass nylon, durable nylon material, gypsum materials, aluminum, titanium, stainless steel, silver, gold, rubber-like material.

3D printing technology is not used in mass production, so some experts advocate 3D printing is the third industrial revolution, this argument is just agimmick.Foxconn OEM for Apple iPhonehas been for many years.Gou made​​ with 3D printing phones to illustrate 3D printing products can not only see, because we can not add electronic components, electronic productscan not be produced as the amount of these products.3D printing even without the production of electronic products,but by material constraints,other products can be produced very little, “even if the products produced, can not mass production, but also on the brokenYishuai.
“3D printingis indeed more suitable for some small-scale manufacturing,especially high-end customized products, such asauto parts manufacturing, although the main material is plastic, but the future of metallic materia ls will certainly be applied to 3D printing in the past,” said Crump, 3D printing technology has entered thedental, jewelry, medical industry,the scope of future applications will be more widely available.

Quality control for plastic injection molding in china

Parts made in a plastic injection molding process can have their own unique set of possible defects. That is why all of our employees are trained to spot these problems. The following is a listing of the most common defects associated with the plastic injection molding and transfer/compression molding processes:

Sink Marks: Sinking is caused by the outer skin of plastic solidifying while the material inside is still molten and viscous. As it cools and solidifies, the material compacts . The best way to avoid these dimples is to design the part with a consistent wall thickness. However, many times the effect of the sink mark can be minimized by adjusting molding parameters such as injection pressure and time.

Gas marks (burning): When molten plastic is injected into a mold cavity, the air that is in that cavity needs a place to escape. If the hot compressed air cannot escape, it may leave burn mark on the part. The best way to avoid gas marks is to strategically locate air vents of the proper depth within the mold. Adjustments to process parameters such as injection speed and screw speed can be altered to reduce or eliminate burning.

China injection molding and plastic mold making industry hard

injection molding

Injection Molding in China

From China’s income situation difficult to see Chinese private enterprises, including ours plastic injection molding industry,The U.S. has 70% of the injection molding industry to move back, and if China plastic mold injection molding industry to continue to survive, to break the monopoly of state-owned enterprises is inevitable.

Chinese household financial investigation and Research Center data show that “the financial industry, utilities, real estate is the highest level of annual wage income of three industries, other industries typically 1.9 to 2.6 times.” Investigation of the center come from different ownership enterprises wages of view, state-owned enterprises, the average wage level of 54,000, only 29,000 private enterprises, state-owned enterprises is the private sector average wage level is about 1.9 times. The average wage income of foreign companies is as high as 86,000.

“State-owned monopoly industries due to hold the telecommunications, electricity, energy, high-value resources, it was easier profitable addition to pay state taxes, as well as considerable profit retention by allowing for the issuance of employee benefits or develop shopping malls, resorts, hotels and other sideline; The relative crowding together in the competitive private manufacturing, consumer goods, foreign trade and other fields. junior staff the income gap between the two conservative estimate of about 2 times. “Zou Wenjiang said.

Analysis of state-owned enterprises pay system is not difficult to find, in addition to employees of state enterprises fundamental wage income, but also includes wages of hidden income, such as a variety of bonuses, subsidies, insurance, prepaid cards, in-kind and other benefits. Industry insiders estimate that this part of the income of employees of state enterprises accounts for about half of total revenue.

Chinese household financial investigation and research center director, dean of Southwest University of Finance and Economics plow willing to accept new financial reporter in an interview that, according to various sources of income contribution to income inequality perspective, wage income gap is caused by China’s current income uneven distribution of one of the main income gap on the overall contribution rate of 40 percent. Followed by the industrial and commercial income disparities, income up 20% of households with an average income of 22,000 yuan business, the average household income of the lowest 20% Business operating income of only 200 yuan. Typically, the main source of income of low-income households or agricultural production, 20% of the lowest-income households, accounting for nearly 50% of agricultural income, wage income and business income accounted for only 13% and 5%. This reflects the current low rate of return of agricultural production reality.

china injection molding and mold making industry with the recession

china injection mold

china injection molding

As has been the China Europe customer service injection molding and mold manufacturing plant, we feel the order is very intuitive and sensitive, China’s official manufacturing data released in July rose slightly, with the outside world last month, the Chinese economy had negative growth not as expected.

But by the HSBC (HSBC) at the same time released independent survey said that “Chinese manufacturers face significant deterioration in the business environment.” For this argument, China injection molding and mold makers are very much support, both from China Order injection mold or injection products, this year’s decline in new orders in large quantity, we are still doing the old customer’s order last year, but next year how kind of hard to say.
China officially released on Thursday July the government purchasing managers’ index (PMI) increased from 50.1 in June to 50.3, which means that manufacturing conditions improved slightly. However, the release of China HSBC PMI index fell to 48.2 in the previous month, but July’s 47.7 for the 11 months to the lowest level.

For the manufacturing sector, PMI reading above 50 indicates expansion in manufacturing, production is less than 50 indicates contraction. Most analysts had expected in July will be the official index fell below 50, they pointed out that China’s overall economy is continuing to slow. Injection molding industry with respect to China, the Chinese mold making opportunity is good, but now Chinese social values ​​make fewer and fewer good injection mold maker, this is affecting the Chinese mold and injection molding industry.

HSBC and the differences between the official data will be re-triggered a kind of market speculation: Chinese government is trying to show a more optimistic picture of the Chinese economy, to support the people’s confidence in the Chinese economy, despite slowing economic growth.
ANZ Bank (ANZ), chief China economist Liu Ligang (Liu Ligang) said that official data “will not change our overall assessment that Chinese economy continues to deteriorate.”

In recent weeks, Chinese officials seem to have begun to take the initiative to stabilize investor confidence of economists and commentators, so they believe that despite three years of China’s economic growth to slow down gradually, but the Chinese economy in good condition.
Two findings appear gaps, one possible reason is that HSBC survey focused on relatively small-scale private manufacturers, while the official PMI index mainly reflects the large-scale state-owned enterprise situation.
Not only is China the actual molds and injection molding industry slowdown in other sectors is not good, but a lot of excess capacity in the current circumstances it is not necessarily a bad thing, China mold manufacturing and injection molding industry need to rely on technology development, rather than by selling mold like selling iron did survive. Labor advantage is gone, China mold manufacturing and injection molding industry to rely on technology and management to survive.
