Important Terms to Know About Plastics Molders Compression Plastic compression molders are designed to place plastic into molds of various shapes. Also referred to as plastics extrusion, this process is ideal for high-volume manufacturing operations. Raw plastic material is first melted then formed into a shape, to create tubing, pipes, tools and more. Check out these important terms about plastic compression molders:
Injection Molding: This state of the art injection molding equipment manufactures objects from thermoplastic and thermosetting plastic materials. From design assistance to rapid prototyping, companies in the plastic compression molding business offer many services, whereby the material is placed into the mold by a heated barrel. It then cools and takes on the intended shape:
Polymer: Made up of repeating structural units, this large molecule bound by covalent chemical bonds is commonly known as plastic. Plastic can either be natural or synthetic in nature.
Plastics Extrusion: A high volume manufacturing process involving the melting of raw plastic. This plastic can be formed into objects like pipes, tubing, weather stripping, fencing and deck railings. You can also create coatings, plastic films and wire insulation.
Thermoforming: Designed for thin and heavy gauge plastic applications, this plastic production process involves a vacuum that pulls a sheet of plastic over a heated mold. It’s left to cool and then can be separate easily from the mold.
Thermal Insulation: This term refers to a reduction in heat transfer between objects near heated components, specifically in regards to the maintenance of a temperature gradient through insulation in the case of reduced heat flow.
Hot Stamping: This process involves applying a stamp for decorative or functional purposes. Hot stamping takes place on the plastic material while still hot.
