Extrusion is a manufacturing process where heated plastic raw material granules are pushed through a shaped die to form a consistently shaped profile.
In the case of plastic extrusions, the process begins by feeding plastic granules into an extruder machine. Inside, the material is heated until molten and then forced through a die that shapes the profile. Once formed, the profile is cooled with water and cut to length. The key feature of extrusion is that the profile maintains the same cross-section along its entire length. At MKM Extrusions, there is a huge variety of shapes and sizes available on their easy to use online shop. They also offer a custom plastic extrusion service for larger production run, subject to review by our technicians.
