14. 2. Specific injection molding processes In order to optimize molded parts, injection molding has diversified into about 15 different techniques, with specific know-how that is often specific to a small number of companies. There are processes to increase productivity, quality and size of molded products. 1. Fast run injection molding This applies to thin parts and high production rates, such as with lids, caps, closures, pots for the food industry, disposables, CDs, etc. The injection molding presses are fast and well stabilized to avoid vibrations, with multi-cavity molds and hot runner systems.
Outset injection When installing an insert, the volume of the metal is always much smaller than that of plastics in the finished part. There is also the reverse process, called outset, which consists of injecting a polymer on a supporting metal plate, of much larger volume than that of the molded material. 25. Outsets (plates for appliances) It is thus possible to obtain, in a single operation, chassis for mechanical or electrical devices that bear all the controls. The metal provides rigidity and the plastics integrate all functions, replacing all the cross frames, bosses and other elements that should have been screwed-on or riveted in a standard mounting operation, thus resulting in very high productivity gains when assembling.
However, small parts can accept a standard operation. 20. 6. Injection-intrusion on several molds The injection press is mobile, by rotation, in order to feed the molds arranged in a semi-circle (carrousel). 21. Injection-intrusion on several molds The operation time is thus reduced just by a deposit of polymer in the mold (intrusion). However, since the injection pressure is not maintained, the molded parts may lack cohesion. Typical application: shoe soles made of PVC or PUR. 7. Heavy injection molding Heavy injection molding means using presses of over 2,000 ton clamping force.
