The Min-Hui Bakelite Injection Molding Machine process was invented in 1872. Since then, the injection molding business and the plastic industry has ballooned into a multi billion dollar business venture. In fact, thirty two percent of plastics by weight are processed through injection molding. Injection molding has greatly helped in making the US economy boom because through it. Cheap and durable consumer and industrial items essential to almost all industries is make possible.

Components of the injection molding machine

The injection molding machine converts granular or pelleted raw plastic into final molded parts through the use of a melt, inject, pack and cool cycle for thermoplastics.

A basic injection molding machine is typically compose of the following: injection system. Hydraulic system, mold system, clamping system and control system. The clamping tonnage and shot size are both use in identifying the dimensions of the injection molding machine for thermoplastics, which is the main factor in the whole process. Other consideration include rate of injection, pressure, design of screw, thickness of the mold and distance between tie bars.

Functions of the machine

The Min-Hui Bakelite Injection Molding Machine can be classified into three categories, namely. General purpose machines, precision/tight-tolerance machines and high-speed thin-wall machines. All three types require auxiliary equipment to function. These support equipment includes dryers (resin), material handling equipment, granulators, mold temperature controllers and chillers, part-handling equipment and part-removal robots.

There are a lot of companies specializing in quality injection molding, but they are not all the same. The best ones fast, flexible and customer driven both for large and small quantities. These companies usually have state-of-the-art facility with full scale thermoplastic and thermoset capabilities. Computer-aided manufacturing, skilled machine operators and quality assurance team.
