Injection molding is carried out by using pellets obtained by suspension polymerization as raw materials and molding on a conventional plunger type or screw type injection molding machine. It should be noted that due to the poor fluidity of the acrylic particles, the flow resistance of the injection molding system is small, and the gates should be larger in size, the surface of the cavity and the runner should be smooth, and post-treatment is required after molding. To eliminate internal stress.
Extrusion molding is to form acrylic sheets, rods, tubes, sheets, and the like by extrusion polymerization of acrylic pellets. The acrylic products produced by extrusion molding have low molecular weight, weak mechanical properties, low heat resistance and solvent resistance, but the high production efficiency and high product flexibility of the process are favorable for bending and thermoforming processing.
Is the acrylic board pvc?
Acrylic and PVC are two very different materials. The PVC board is made of PVC and has a honeycomb structure with a cross section. It is a vacuum plastic film used for surface coating of various panels, so it is also called decorative film and adhesive film. It is used in many industries such as building materials, packaging, medicine and so on.
