Know it all About Injection Molding

Plastic injection molding is a process that forces the liquid plastic into a mold to give shape to customised plastic name plates, plaques, signs and product branding elements. As soon as the plastic cools and solidifies, it releases from the mold to form variety of plastic parts that can be utilised in any industry. the impact of injection molding is much bigger than we think on the industry. Since its inception in 1872, the process of injection molding is much bigger than you can think on economy. This multi-billion dollar industry manufactures around 32% of plastics by weight. Because of this process, the construction of a lot of durable consumer and industrial items important to us are made cheap.

There are many diverse types of injection molding and as many different types of plastic injection molding machines to go with it. Some of the more common types of plastic molding are standard mold injection, insert molding, plastic extrusion, blow molding, multi-color or material molding, stack molding, and rotary molding. A injection molding machine is made up of the following components: injection system, hydraulic system, mold system, clamping system and control system. While clamping tonnage and shot size are usually used to quickly identify the size of the injection molding machine for thermoplastics.

The basic functions of the injection molding machines are as follows.

1. Injection molding machines are classified into three categories namely based on machine function: general purpose machines, precision tight-tolerance machines and high-speed, thin-wall machines.

2. These machines operate using auxiliary equipment, the most important of which include resin dryers, materials-handling equipment, granulators, part-removal robots, mold-temperature controllers and chillers and part-handling equipment.

Companies who are looking for injection molding in China, should do thorough research first and only go with a reliable company providing injection molding.
