Plastic Mold Injection Process
As discussed above, the typical injection molding machine consists of five major components:
Hydraulic Pump, Motor and Gears
Stationary & Movable Patens
For some projects, there may be a need for In-Mold Decoration (IMD) to include an image or coating on a plastic surface. This process involves printing a high-quality image on a heat resistant plastic film that will hold up to the stress of in-molding. The printed film is inserted into the open plastic injection mold and held in place via vacuum ports or electrostatic charge while the mold is closed. Once closed, plastic resin is injected into the mold, thus encapsulating the label to the finished part. Combining the decoration process with the molding process adds durability, decreases manufacturing costs by eliminating post-molding labeling, handling and storage, and also allows for design flexibility. IMD allows for a wide range of colors, effects, textures, graphic options and can replicate stainless steel, wood grains and carbon fiber. IMD is commonly used used on washers and dryers because of its affordability and durability.
