Hollow blow of the current market situation machinery

Since China's pull plastic molding injection blowing hollow, why not commercial level? The author thinks there are mainly four reasons.
A development thought, some mistake

Development of conveyor chain, the enterprise only empty weight, mould development main development. Hollow blow molding machine, plastic injection moulds and host is the combination of the equipment from the host and the importance of the mould, host only 40% of the machine, and mould to 60% of the machine. Host is not equal to the successful development of successful development, mould, only host and successful development, both to say, blow molding plastics injection development success. Hollow Japan's "three stations" and Japan, "four stations" models are the key technologies, and some of our mould factory in the development of plastic injection molding, blow hollow plastic process, no correct understanding to the host and the mold of the relationship between the development value, the host, and no more important in developing molds, failure reasons in this.

Second, mould technology reach the required level

Hollow conveyor chain, plastic injection mold is different from the injection molding, has its own characteristics. Hollow blow molding machine, plastic injection mould, the key is injected, mould casting mould for its properties of materials with special requirements, heat and cold, heat transfer coefficient of small, high efficiency, high heat conductivity, die structure for hot runner form. From the perspective of China mold technology level, also can produce to develop the quality standards and blow molding plastics injection mould hollow. According to the understanding of mould, plastic injection molding, blow mould adopts hollow what kind of material is not clear, how to develop die?

Third, the lack of investment. Mould

Lack of investment, make the mold factory technical level. According to understand, foreign manufacturing plastic blow molding machine, injection mould of hollow, have their own note pull plastic molding, blow hollow out of the mould are developed in the host, repeatedly until the requirements. Domestic haven't developed a blow mould for plastic injection molding machine and the hollow blow mould and purchase, plastic injection molding machine as hollow trial-manufacture equipment.

Four, manufacturers and lack of cooperation factory

Manufacturers must cooperate with factory, a division of labor and the risks. This is the overseas development hollow blow molding machine, plastic injection of experience. For example, Japanese company and Japan aoki solid for their fine company, factory, by manufacturers of request, and then into the factory was developed by users. But we have to "one-step manufacturers itself," pull plastic molding injection mould hollow blow not understand the situation, for saving cost, his research results, not only the manufacture of moulds, reach the standard of quality products, but also make host image produced adverse effects.
