Forming definition
Plastic molding processing refers to the process of making final plastic products from polymers manufactured by synthetic resin manufacturers. Processing methods (usually referred to as one-time plastic processing) include compression molding (compression molding), extrusion molding (extrusion molding), injection molding (injection molding), blow molding (hollow molding), calendering, etc.
Blister
After the sheet is heated to a certain temperature by a blister machine, the plastic sheet is adsorbed on the surface of the model through a vacuum pump to generate negative pressure, and the plastic sheet is cooled and shaped to be transformed into different shapes of blisters or blister shells.
Extrusion
Extrusion, also known as extrusion molding, is a method of using an extruder (extruder) to continuously pass heated resin through a mold to extrude products of the desired shape. Extrusion is sometimes also used in the molding of thermoset plastics and can be used in the molding of foam plastics. The advantage of extrusion is that products of various shapes can be extruded, the production efficiency is high, and it can be automated and continuous production; the disadvantage is that thermosetting plastics cannot be processed by this method widely, and the product size is prone to deviation.
