Wood-plastic composite

Polyethylene-based WPCs are by far the most common. Additives such as colorants, coupling agents, UV stabilizers, blowing agents, foaming agents, and lubricants help tailor the end product to the target area of application. Extruded WPCs are formed into both solid and hollow profiles. A large variety of injection molded parts are also produced .

Blowing agent

When the melt is molded or extruded and the part is at atmospheric pressure, the gas comes out of solution expanding the polymer melt immediately before solidification. Frothing akin to beating egg whites making a meringue , is also used to stabilize foamed liquid reactants, e.g. to prevent slumping occurring on vertical walls before cure – i.e. avoiding foam collapse and sliding down a .

What Are Aluminum Extrusions?

Aluminum extrusions are shaped pieces of aluminum that are manufactured in long strips. If you cut pieces of extruded aluminum to the same length immediately after it's extruded, the cross-sectional profile should be exactly the same for each piece. Extrusion is especially compatible with aluminum's

Plastic extrusion

Extruded tubing, such as PVC pipes, is manufactured using very similar dies as used in blown film extrusion. Positive pressure can be applied to the internal cavities through the pin, or negative pressure can be applied to the outside diameter using a vacuum sizer to ensure correct final dimensions. Additional lumens or holes may be introduced by adding the appropriate inner mandrels to the die.
