The main function of injection molding and types of Injection Molding

February 13 , 2023

Injection molding (IM) technology is mainly used to manufacture plastic parts. In fact, almost one-third of everything you see around you today is made using injection molding technology: device cases, cases, office supplies, mugs, and more.

Types of Plastic Injection Molding
There are many different types of plastic injection molding, each with its own advantages and disadvantages. The following are general types:

Types of rotational molding:
Rotomolding - Using this technique, material is placed in a mold and rotated slowly over a heated oven. The material begins to melt and adhere to the inner surface of the mold, forming the object layer by layer. Rotomolding allows the manufacture of a wide range of simple to complex shapes, such as industrial tanks, without the need for gluing or welding.

Extrusion - This method involves pressing molten material (usually plastic) into holes in a two-dimensional die. It goes through a series of molds, where it gets its shape after melting. When the product is ready, it forms a long two-dimensional shape that can be cut into multiple parts.

Metal Injection Molding - A metalworking process. After forming a block from metal powder and binding material, it is shaped and cured using injection molding techniques, and the part is then post-processed at high temperatures. Finally, the binder is removed and the powder is sintered to obtain the product.

Reaction Injection Molding (RIM) - Using a thermoset polymer instead of plastic, after being compressed in a mold, the block is mixed with a catalyst and left to cure. The most common reaction injection molding material is polyurethane.

Liquid Silicone Injection Molding - Very similar to Reaction Injection Molding (RIM): Liquid silicone (rubber) is injected into the mold and then cured. This technique can be used to evaluate different material configurations prior to full production.
