Forming process of acrylic sheet

Wider Stripe Acrylic Sheet

Acrylic molding processes commonly used in industrial production include casting, injection molding, extrusion, thermoforming, etc.

Casting molding is mainly used for the molding of acrylic sheets, bars and other profiles, and the molded products need to be post-processed before they can be used. Cast Acrylic Sheet has strong stiffness, strength and excellent chemical resistance, and has unparalleled flexibility in color system and surface texture effect.

Injection molding uses pellets obtained by suspension polymerization as raw materials, and is molded on a common plunger or screw injection molding machine. It should be noted that due to the poor fluidity of acrylic particles, the flow resistance of the injection molding system should be small, the gate should be a larger side gate, the surface of the cavity and runner should be smooth, and post-processing is required after molding. to relieve internal stress.

Extrusion molding is to extrude the acrylic particles produced by suspension polymerization into acrylic sheets, rods, pipes, sheets, etc. Acrylic products made by extrusion molding have low molecular weight, weak mechanical properties, low heat resistance and solvent resistance, but this process has high production efficiency and high product flexibility, which is conducive to bending and thermoforming.
