The process "Injection Molding" was invented in the year 1872, from then on, the plastic injection molding business and the plastic industry has seen a big boom. It has become a billion dollar business venture. The fact is that 30% of plastics are processed through injection molding. Injection molding as said earlier has brought in a big boom with loads of boon. Through this process, cost effective and durable consumer and industrial products, necessary for almost all industries is made possible. This kind of injection molding equipments are generally used in several industries, which include, oil and gas, automobile, food processing and many more. It is mainly used in agriculture industries, for making spray control nozzles and other agriculture plastic moldings equipments.
Different components of Injection Molding Equipments
The injection molding equipment transforms the pelleted or granular raw plastic into final molded products, by using a melt, an inject, pack and cool cycle of thermoplastics.
A basic, proper injection molding equipment is made of the following components – hydraulic system, injection system, clamping system and control system.
Three categories of the equipment
This machine can be classified in to three categories, which include general purpose machines, precision tight tolerance machines and high speed thin walls machines.
As said earlier the injection molding machine consists of injection unit, the mold and the clamping unit. The process involved in plastic injection molding is not as tough as the size of the equipment. It is a very simple and a systematic process. Initially the process starts with the injection of plastic resins or polymers in to the injection barrel. These resins are heated to the melting point and now the fluid is then poured in to the mold of the desired shape as needed.
The plastic takes the shape of the cavity or the mold which is used; the molten plastic takes the shape and get solidified or settled in it. Once it is solidified the product gets ejected out from the machine’s cavity. The same cavity can be used to produce any number of molds, of our desired shape.
