Analysis of the problems of hollow blow molding machine

   Since the injection blowing hollow blow molding machine Chinese why has not yet reached the level of commercialization? Zhangjiagang Feite Plastics Machinery Co. Ltd. that mainly has the following four reasons.

First, the development of ideas there are errors

Development of hollow plastic molding machine, enterprises only host development, ignoring the development of mold. Injection blowing hollow plastic moulding machine is a combination of host and mold equipment, from the host and die on the importance of the two, the host accounted for only 40% of the whole machine, and the mold to account for 60% of the whole machine. The host is not equal to the successful development of the development of success, only the host and die together to develop successful, successful development of injection drawing blowing hollow plastic moulding machine. The key technology of Japan's "three position" and Japan's NISSEI type "four position" model is the mold, and some of our plastic machinery plant in the development process of injection drawing blowing hollow plastic moulding machine, does not have the correct understanding of the relationship between the host and the mold, only attach importance to the development of the host, but not the development of the mold on a more important the main reason for the failure of this position.

Two, mold technical level can not meet the requirements

Mold injection blowing hollow plastic molding machine in injection molding, has its own characteristics. Mold injection blowing hollow plastic molding machine, the key is injection molding parison, mold material has special requirements for its performance, thermal expansion and contraction coefficient of small, high thermal efficiency, high thermal conductivity, the mold structure for hot runner form. From the current China mold technology level, but also can create the development of mould injection drawing blowing hollow plastic moulding machine to achieve quality standard. It is understood that the mold of injection drawing blowing hollow plastic moulding machine and some mould factory is what kind of materials are not clear, how to develop the mold?

Three 、 die factory lack of investment

Die factory lack of investment, so that the mold technology level can not be developed. It is understood that the foreign development and manufacturing of injection drawing blowing hollow plastic moulding machine mould factory, has injection drawing blowing hollow plastic moulding machine developed by ourselves, the mold must be repeated in the host test, until the meet the requirements. While there is no a mold factory for mould manufacturing injection drawing blowing hollow plastic moulding machine and buy injection drawing blowing hollow plastic moulding machine as production equipment.

Four, the host factory and die factory lack cooperation

Host factory and mold factory must cooperate, both have division of labor, joint development, each risk. This is the overseas development of injection drawing blowing hollow plastic moulding machine experience. For example, Japan Aoki solid company and Japan NISSEI company have their supporting mold factory, the host factory request, mold factory for research and development, and then submitted to users. And some of our host plant itself on the "one-step" injection blowing hollow plastic molding machine mold is still not very understanding of the situation, in order to save the cost of design, mold manufacturing, their results, not only products not up to the quality standard, and the host image produced a bad influence.

Zhangjiagang Feite Plastic Machinery Co., Ltd. is a professional engaged in plastic hollow blow molding machine design, manufacturing and sales and service of high-tech enterprises. Production from 1 ml to 2000 liters of automatic plastic hollow molding machine (blow molding machine, blow molding machine), especially in the large hollow machine manufacturing field, technology has been in the domestic leading level. Fit 100 plastic machinery has many years of mature automatic hollow molding machine R & D and manufacturing experience, blow molding machine can produce 5 ml of -1000 liters of various bottles, barrels, pots, tool bags, desktop board plastic hollow products, including PE, PP, PVC, PC, PA, ABS, PETG, TPU, EVA, EVOH, TPE, PPE and other plastic materials
