So knowing what are the screw slippage reasons and treatment of injection molding machines is very important for every plastic injection moulding engineer and factory or workshop manager. When the injection screw is difficult to press the material at the feeding port, or the length of the barrel cannot form enough adhesion to convey the material, then the screw will slip. In the stage of screw pre-molding, when the screw rotates in the barrel to convey the material along the direction of the screw and retreats to accumulate the material for the next injection, the screw will also slip. If the screw starts to slip during the pre-molding phase, the axial movement

With various molds available, it is essential to understand the basics of each kind to make an informed decision about which type of mold is right for your project. Pipe fitting molds fall under three categories: extrusion, die casting, and forging. Extrusion molds, made from metals, plastics, and composites, are typically used to create smaller pipe fittings such as elbows, tees, and reducers. Die casting molds, made from metals, generate larger pipe fittings like flanges and couplings. Forging molds, also made from metals, create the most common type of pipe fitting. Each type of mold has its own set of benefits and drawbacks. Extrusion
