Purging Compounds. Compression Molding process, Transfer molding, Injection & Blow Molding-Detailed: The types of molding processes are based on the type of plastics we use. In particular, it is necessary to cool a thermoplastic part before removing it from the mold, and this requires that the mass of metal making up the mold also be cooled and then reheated for each part. Thermoforming is a single sided process where only one side of the sheet can be controlled by the tool surface. Wilbert Plastic Services provides plastic injection molding, heavy gauge thermoforming, custom plastic molding and more throughout the United States. Two opposing molds come together with the heated sheets between them. Figure 1 shows the process window for an injection molding process in terms of the injection velocity and pack pressure. The production time of the mold for thermoplastic injection depends on the complexity of the mold. Click on any of the headers below to expand the category. Scientific Process Development: Beyond Tribal Knowledge Molding Scientific Process Development: Of the dozens of settings that be managed via a modern injection molding press control, only a small number will prove to be critical for the cost-effective manufacturing of a given part. Injection molding of a plastic resin can be up to half the cost per pound versus the plate or rod needed for machining; Faster cycle times in the molding process means labor and time saving whereas machining will take much longer per part.
