Plastic Injection Molding Characteristics

Plastic injection molding is the most important processing method for thermoplastics parts. With this method of forming plastic parts, its variety and style as many other molding methods unparalleled. The process is by means of the screw with the thrust, the three-way pipe plastic mold design and implementation of the plasticized plastic melt into the closed mold cavity, the cooling solidification after the mold to get plastic parts. Custom Injection Molding And Plastic Molding Luo Baihui said that the formation of plastic injection molding requires three necessary conditions: First, the plastic parts must be in the molten state into the mold cavity; Second, the plastic solution must have sufficient pressure and flow rate to ensure the timely filling the entire cavity of the various corners ; Third, Custom Injection Molding And Plastic Molding there is a need to meet the shape and size of parts and meet the molding process requirements of the mold. Luo Baihui analysis, plastic injection molding technology and other molding technology compared to its unique advantages, manifested in the following aspects: First, the molding materials, melt plasticization and flow modeling are in the plastic tube and cavity two , The mold can always be in a state where the solution is quickly condensed or cross-linked to cure, thereby helping to shorten the molding cycle; Custom Injection Molding And Plastic Molding the second is to first lock the mold before the plastic solution into the injection, coupled with a good flow of the solution to the mold cavity The wear and tear is very small, so you can use a set of molds in large quantities of complex parts, surface graphics and marking clear and high dimensional accuracy of the products; the third is the molding process of mold, feeding, plasticizing, injection molding, Out of all the molding operations are completed by the injection molding machine, Custom Injection Molding And Plastic Molding so that the injection process is easy to fully automated and to achieve program control. 

But we also have to see the lack of plastic injection molding, due to the cooling conditions, it is difficult to use this technology system without defects, wall thickness changes in the larger thermoplastic products, Custom Injection Molding And Plastic Molding the other because the injection molding machine and injection mold Of the high cost of molding equipment to start a larger investment, so injection molding technology is not suitable for the production of small quantities of products.

Plastic injection molding, also known as injection molding or injection molding, is an important method of forming thermoplastic products. With almost a few thermoplastics, Custom Injection Molding And Plastic Molding almost all of the thermoplastic can be used to form plastic parts. Plastic injection molding can shape a variety of shapes to meet the requirements of many plastic parts. Plastic injection molding has been successfully applied to certain thermosetting plastic parts, and even rubber products in industrial production.

Plastic injection molding process is the granular or powdery plastic from the injection machine hopper into the heated barrel, heated by plasticization into a molten state, by the screw (or plunger) pressure through the barrel at the bottom of the nozzle into the low temperature Of the closed mold cavity, Custom Injection Molding And Plastic Molding the cooling and hardening to retain the mold cavity given by the shape, open mold made of plastic injection molding plastic parts, in the operation to complete a cycle.

Plastic injection molding is an important method of plastic molding, production has been widely used. It has the following characteristics:

① molding cycle is short, can shape a complex shape, accurate size, with a metal or non-metallic inserts of plastic parts.

② the formation of a variety of plastic adaptability. At present, Custom Injection Molding And Plastic Molding in addition to fluoride plastic, almost all of the thermoplastic can be used to form this method, some thermosetting plastics can also be used plastic injection molding.

③ high production efficiency, easy to achieve automated production.

④ plastic injection molding equipment is expensive, mold structure is more complex, high manufacturing costs, so plastic injection molding is particularly suitable for mass production.
