The plastic injection molding process begins with generating the product design, followed by tooling a mold to fit the product design, melting the plastic resin pellets, and injecting the molten pellets into the mold using pressure. Steps Designing the Product Designers build a part using fundamental design rules related to the injection molding method. Create a Tooling Mold to Fit the Product Design Highly trained machinists and toolmakers use the product design to create a tooling mold for the injection molding machine. A tooling mold, also known as a tool, is the heart and soul of an injection molding machine. They are meticulously built to house the negative cavity for the product design as well as extra features including sprues, runners, gates, vents, ejector systems, cooling channels, and moving components. Tooling molds are constructed from steel and aluminum grades that can survive tens of thousands of heating and cooling cycles. Mold manufacturing can take up to 20 weeks to c...

Plastic extrusion is a manufacturing process used to create objects with a fixed cross-sectional profile. It involves pushing raw plastic material through a heated barrel, and then forcing it through a die to form the desired shape. Here's a breakdown of the process: Raw Material Preparation : Plastic pellets or granules are fed into a hopper. The material can be virgin resin or recycled plastic. Melting : The plastic material is fed into an extruder, which consists of a rotating screw inside a heated barrel. As the screw turns, it applies heat and pressure to melt the plastic. Extrusion : Once melted, the plastic is forced through a die, which determines the shape and size of the final product. The die is typically custom-made to produce specific profiles such as tubes, pipes, rods, or sheets. Cooling : After exiting the die, the plastic is cooled using air or water to solidify its shape. Cooling is crucial to maintain the desired dimensions and structural integrity of the produc...
