Equipment and Materials
To create plastic extruded profiles, a plastic extrusion machine must be used. The extruder machine consists of a hopper, barrel with a screw inside, heaters, and the motor to operate the screw drive.
An extrusion die will also be used. Plastic extrusion dies serve as the mold for molten plastic. They create the shape or profile of the extruded plastic. Plastic extrusion dies are usually custom made, according to the customer’s specifications, using software to create the die design. Standardized dies are also available. Dies are then cast out of metal materials to withstand the high temperatures of molten plastic.
The raw thermoplastic material is an important component in the extrusion process. The temperature needed to extrude the plastic is determined based on which material is being used. The material will also determine how many screens are needed to filter out unwanted materials or impurities. There are many kinds of thermoplastic material available for extrusion, but the most common form is resin plastic. Plastic in the form of flakes, granules, or powder is typically used in the hopper. Small beads of resin are easier to load into a hopper and have quick melting times due to their size.
