Currently, required volumes are runs of 100,000 to 1 million units, or more. 2. 3. Basic plastics As a rule, all thermoplastics pellets can be injection molded: – PE-HD, PP, ABS, generally to make large parts; – PE-LD, flexible PVC, PS, PMMA and engineering plastics, more often for smaller size parts, and relatively little rigid PVC that is difficult to mold. Thermoset plastics and vulcanizing elastomers can also be injection molded, by heating the mold above the plasticization temperature to achieve polymerization or vulcanization.

It reaches temperatures of 40 to 60°C, through the operation, for easy to mold plastics. For some polymers, the mold may be heated to more than 100°C, but it still remains relatively cold, compared to these polymers, so that they can solidify. 28 Plastic Forming Processes The injection pressure may reach up to 1,000 bars. The pressure in the mold is about 50% of this value, because of losses. Practically, and for commodity plastics, the injection pressure is about 300 bars. It is important to close the mold securely.

7. Heavy injection molding Heavy injection molding means using presses of over 2,000 ton clamping force. The largest injection molding presses may have a clamping force of up to 10,000 tons, which is the equivalent volume of two locomotives. Such presses can mold about 100 kg. The split by injection press type is approximately as follows. Injection type Small Medium Large Very large Injection molding press clamping force in tons < 200 200 to 800 800 to 2,000 > 2,000 Mesh presses are sometimes used.
