WebbWhen injection of the liquids into the mold begins, the valves in the mixhead open. The liquid reactants enter a chamber in the mixhead at pressures between 100 and 200 bar, and they are intensively mixed by high-velocity impingement. From the mix chamber, the liquid then flows into the mold at approximately atmospheric pressure.

Webb30 sep. 2013 · The process is called thermoplastic foam injection, or FIM. The techniques offer several advantages over conventional injection molding. For one, they save up to 30 percent in material. For another, the components are less distorted, i.e. have fewer dents. In addition, designing is easier for engineers. WebbIn the Thermoplastic Foam Injection Moulding Process (TSG) moulded technical parts are made with a foam core and non-foam surface layers, so-called integral foams. In principle, the TSG process can be applied to a variety of injection moulding products. But the surface will always maintain a silvery texture.

Webb19 dec. 2024 · The thermoplastic injection molding process starts with the addition of pellets to a hopper. Thereafter, the material is passed through a heated barrel where the rotation of the screw initiates a shearing action causing the pellets to melt.
