WebBlow molding is a manufacturing process that involves turning plastic material into a hollow plastic component. The first step is melting and extruding plastic pellets into a tube (i.e., parison). The tube is then enclosed within a pre-formed mold. Next, air is blown into the contained tube to force the material to conform to the shape of the mold. WebInjection Molding. In injection molding, the material melts and is then injected under pressure into a mold. The liquid plastic cools and solidifies. The operation can be carried out with many materials (metals, glass, thermoplastics, etc.). However, the most commonly used are. Polypropylene (PP) represents about 38% of the world's production.
