Plastic Extrusion Molding

Extrusion molding is molding plastic or metal into a predetermined shape. Metal or plastic is melted and forced through a die to create a linear form.

Plastic Extrusion Molding


Plastics or metals can be extruded into predefined shapes using extrusion molding.


The linear form is created by melting metal or plastic and passing it through a die.



After cooling, the final shape is commonly called a rod.


Though it is not necessarily cylindrical, it can be cut into various lengths for various applications.



The exact number of variables apply to extruding materials as to injection molding.

It is possible to adjust several factors to create ideal material conditions, such as the temperature of the material, the pressure applied to the die, and the time of extrusion. Extrusion molding is similar to injection molding in that it melts and forms plastic or metal into predefined shapes.


On the other hand, I prevent the plastic or metal from continuously extruding with injection molding.



The mold or die fills with material, the material cools, 

and then it opens to drop pre-formed shapes into a container.



Excluding processors and color finishing, about 600 uniform classification units for injection molded plastics are available. However, the producers of plastic materials themselves have difficulty meeting the needs of their customers. FRP molds used for the extrusion process require high pressure to extrude precision plastic products with accurate dimensions and tolerance.
