Kamano pakeng tsa boholo ba hlobo ea ente le ho honyela ha polasetiki
06 30Thermoplastics e khetholloa ka ho atolosoa ka mor'a ho futhumatsa le ho fokotseha ka mor'a ho pholile. Ha e le hantle, molumo o tla fokotseha ka mor'a khatello ea maikutlo. Ha ho etsoa ente, polasetiki e qhibilihisitsoeng e qala ka ente ka mokoting oa hlobo. Ka mor'a hore ho tlatsoa ho phethoe, thepa e entsoeng ka ho qhibilihisoa e pholile ebe e tiisa. Ha karolo ea polasetiki e ntšoa ka har'a hlobo, ho fokotseha hoa etsahala. Ho honyela hona ho bitsoa ho etsa shrinkage. Nakong ea ho tloha ha hlobo e ntšoa ho tsitsisa karolo ea polasetiki, ho ntse ho tla ba le liphetoho tse nyenyane ka boholo. Phetoho e 'ngoe ke ho tsoela pele ho honyela. Ho honyela hona ho bitsoa post-shrinkage.

Le hoja sebopeho sa hlobo se ka fapana haholo ka lebaka la mefuta-futa le ts'ebetso ea polasetiki, sebōpeho le sebopeho sa lihlahisoa tsa polasetiki, le mofuta oa mochine oa ente, mohaho oa motheo o tšoana. The ente hlobo haholo-holo e entsoe ka likarolo tse tharo: tsamaiso ea gating, likarolo tse bōpiloeng le likarolo tsa sebopeho. Har'a tsona, tsamaiso ea ho tšela le likarolo tse bōpiloeng ke likarolo tse amanang ka ho toba le polasetiki le ho fetoha ka polasetiki le sehlahisoa. Ke likarolo tse rarahaneng ka ho fetisisa le tse feto-fetohang ka ho fetisisa ka har'a hlobo ea polasetiki, e hlokang qetello e phahameng ka ho fetisisa ea ho sebetsa le ho nepahala.

Theknoloji ea ente ea hlobo e chesang
03 09Hot runner gating system can be understood as an extension of injection molding machinery. The function of the hot runner system is to deliver the thermoplastic melt to the vicinity of the molding die or directly into the die adiabatically. The hot runner can be heated independently, but thermally insulated in the injection mold, so that it can individually compensate for the heat loss caused by contact with the "cold" mold. Hot runner molds have been successfully used to process various plastic materials. Almost all plastic materials that can be processed with cold runner molds can be processed with hot runner molds.

Thinning of automobile plastic bumper
03 04The car bumper is one of the relatively large trim parts on the car. It has three main functions: safety, functionality and decoration. There are three main ways to reduce the weight of automobile bumpers: material lightweight, structural optimization design, and manufacturing process innovation. Material lightweight generally refers to replacing the original material with a material with a lower density under certain conditions, such as replacing steel with plastic; the structural optimization design of the lightweight bumper mainly includes thin-wall technology; the new manufacturing process includes micro-foaming New technologies such as materials and gas-assisted molding.
