The whole, China plastic mould whether in quantity, or in quality, technology and ability has made a great progress, but with the needs of the development of the national economy, the world advanced level, compared to a gap still. Some large, sophisticated, complex,the long life of high-grade plastic mould still need to import a lot of every year. In the total amount of demand exceeding supply at the same time, some cheap plastic mold but supply exceeds demand, market competition is intense, and some technical content is too high middle-grade plastic mould also has the trend of supply exceeds demand.8844
Joining the WTO, plastic mold and die industry to bring huge challenge, at the same time bring more opportunities. Because of China's cheap plastic mold to products, product price obvious advantages, some even only 1/5 of the price the foreign product one third to, to join the WTO, foreign similar products to domestic little impact, and cheap Chinese exports of mould is increase; In the high precision mould, before joining the WTO was mainly rely on imports, join WTO, not only for the exquisite products import has brought more convenient, but also lead to more foreign investment to China factory, bring foreign advanced mould technology and management experience, to cultivate Chinese professional mould talents to the role.
in recent years, Chinese plastic mould manufacturing conditions have improved greatly. Large plastic mould has produced single set of weight can up to 50 tons of injection mold, precision plastic mould has reached the accuracy of 2 μ m, precision parts high small module gear mould and reach the requirements of the highlights learn lamp mould etc has also can produce, plastic mold cavity has been able to produce a mode of plastic mold cavity 7800, high-speed mold production speed can have up to 6 m/min above the high-speed plastic different profile extrusion die and the dual chamber co-extrusion profiles, double-color coextrusion, soft hard co-extrusion, were crowded, again of extrusion and low foaming raw steel-plastic co-extrusion, etc. Various kinds of mold. In the production means, mould enterprise equipment to numerical control rate has increased greatly, CAD/CAE/CAM technology has greatly expanded the applications, high speed processing and RP/RT adoption of advanced technologies such as has been more and more, standard mould using coverage and die commercialization rate is greatly improved, the share of mould of hot flow path are improved greatly. In addition, foreign invested enterprise vigorous development of further promoted the plastic mould design and manufacture level and improve the management level of enterprises, some enterprise already informatization management and digital no PIC manufacturing.
as mould design and processing enterprises to raise the level of, mould manufacturing is from the past relies mainly on the transformation of the skills of fitter mainly rely on technology. This is not only the means of production change, and change the way of production and the rise of the concept. This is a trend that the standardization of mould continuous improvement, the precision of more and more high, production cycle is more and more short, fitter proportion more and more low, and finally promote the overall level of the die and mould industry is rising. China mold and die industry at present more than 10 national high and new technology enterprise, about 200 ﹑ high technology and new technology enterprise. And adapt to the trend, the main production mold backbone strength from skill talented person gradually into technology talents is an inevitable requirement. Of course, now and for quite a long time, and highly talented person still very important, because after all, hard to get rid of mould to skill depend on.
existing main problems
China plastic mould industry and foreign standards, mainly exist in the following questions.
(1) the unbalanced development, product overall level is low. Although the inpidual enterprise products has reached or come close to the advanced international level, but overall, the accuracy, the roughness of the cavity surface, production cycle, life index and international advanced level there is a big gap between compared. Including production mode and the overall level of enterprise management, with foreign industrial developed countries there are compared for more than 10 years the gap.
