Plastics are a popular raw material used in making a wide array of products, ranging from tubing to Energy-Efficient Vinyl Window Frames. The plastic profile extrusion process is a common procedure in the plastic-making sector because it`s readily available and easy to deploy. Many companies prefer handling plastics to other materials because petroleum-based products are easy to model. Read on to learn more about the profile extrusion process.
Understanding Plastic Extrusion
The plastic extrusion process is a straightforward procedure that involves melting down resin beads (raw thermostat material), filtering it and then designing it into a given shape. The rotating screw helps in pushing down a heated barrel to a given temperature. The molten plastic is passed through a die to give the final product its shape or profile. Filtering provides the final product with uniform consistency. Here`s a quick breakdown of the entire process.
Step 1:
The process begins by introducing raw plastic products such as granules and pellets into a hopper and feeding into an extruder. Colorants or additives are added if the raw materials don`t have some. A revolving screw facilitates the movement of raw resin through the heated cylindrical chamber.
Step 2:
The hopper`s raw materials then flow through the feed throat to a sizeable spinning screw within a horizontal barrel.
Step 3:
Different materials have different properties, including melting temperatures. As the raw resin passes through the heated chamber, it`s heated to its specific melting temperatures, ranging from 400 to 530 degrees Fahrenheit. The resin is thoroughly mixed by the time it gets to the end of the screw.
