Extrusion molding is a method in which raw materials are put into a barrel to be heated and softened, and the heated and softened plastic is continuously passed through a die with an extruder to extrude a product of the desired shape. Its advantages are that it can extrude products of various shapes, high production efficiency, and can be automated and continuous production; the disadvantage is that thermosetting plastics cannot be widely processed by this method, and the product size is prone to deviation.

Injection molding

Injection molding has high production efficiency, complex and precise products can also be produced, and manufacturing costs are reduced, especially suitable for mass production.
