The present situation and development of injection molding equipment

Our PET bottle preform injection equipment with the filling and carbonated drinks, along with the development of expanding the scope of application of conveyor parts, PET bottle preform of injection molding equipment put forward higher requirement. International PET bottle preform excellent performance of injection molding equipment unceasingly to enter China, promoted the development of China PET bottle, promote the PET bottle preform injection equipment in the progress of science and technology. But we shall see clearly, domestic PET bottle preform plastic molding equipment into a large enterprise that is not in the market stragglers LingQiBaSui rapture, become climate. This paper, based on their understanding of the situation, in view of the above questions, and puts forward some ideas for reference.
Domestic PET bottle preform injection molding machine main r&d single-layer PET bottle preform of injection molding equipment. Although China has developed a certain amount of PET injection molding equipment, but its quality and technology level compared with the international advanced level, are at least twenty years. Domestic PET bottle production unit, the eldest brother without a PET bottle preform of injection molding equipment is domestic, explains this problem. The author thinks that the PET bottle preform injection molding equipment is high, the development of equipment is different from the ordinary thinking injection molding equipment development. Some domestic PET bottle preform r&d unit, as normal, low product to r&d, change the barrel screw machine, such as PET, develop a start on a wrong, so make the route to go wandering in the low level, always. First, the correct development idea to develop as a PET bottle preform injection to research, high-end products can be developed to meet the market performance of conveyor parts preform injection molding machines.
The main performance with PET injection technology progress and continuously put forward new requirements. The mid-eighties, PET bottles used in the initial stage, the hot runner technology is still in the development stage, especially hot runner technology used in PET bottle preform mold cavity, mature enough of PET bottle preform mold is still in the development stage, so to PET bottle preform injection performance requirements are not particularly high requirements, Italy, for example, much new plastic machinery Co., LTD. In Shanghai in 1987 the company's PET bottle preform injection molding machine is the main feature of the screw, mainly introduced to adapt and nozzle PET bottle preform injection molding of other aspects of development, not touch. Along with the development of technology, hot runner of cavity mould development, especially the application of PET bottle into geometric growth of PET bottle preform injection, the performance requirements of higher and higher demands are proposed, PET bottle preform injection molding machine for the development of the market, the adaptive and structural control etc further embody the characteristics and special machine mainly manifested in high-speed, high precision, etc.
