SHEET EXTRUSION
Sheet extrusion is an economical way to manufacture plastic products because machines can operate continuously. The process utilizes resins to create flat, plastic sheets that can be used in other manufacturing operations like thermoforming. It involves the following steps:
- Polyethylene resin granules, color concentrates, and UV additives are fed into a heated cylinder and melted
- The melted plastic is conveyed through a heated screw-and-barrel assembly
- The melted plastic is forced through a flat sheet die
- The plastic is cooled through a set of cooling rolls
The end product is a flat sheet. At Cooper Plastics, we produce thick-sheet extruded HDPE that can be thermoformed into products like:
- Shipping pallets
- Returnable dunnage
- Wheel guards and fenders
- Planter boxes
- Outdoor bins
- Truck bed liners
