Plastics processing from injection to additive manufacturing

« The economics of plastics processing is determined by the type of process. Plastics can be processed with the following methods: machining, compression moulding, transfer moulding, injection moulding, extrusion, rotational moulding, blow moulding, thermoforming, casting, forging, and foam moulding. Processing methods are selected based on equipment cost, production rate, tooling cost, and build volume. High equipment and tooling cost methods are typically used for large production volumes whereas low – medium equipment cost and tooling cost methods are used for low production volumes.[1] Compression moulding, transfer moulding, injection moulding, forging, and foam moulding have high equipment and tooling cost. Lower cost processes are machining, extruding, rotational moulding, blow moulding, thermoforming, and casting. »Wikipedia
