What is Plastic Injection Molding and Why Should You Choose Plasticmold?
Introduction to Plastic Injection Molding Plastic injection molding is a manufacturing process used to produce a wide variety of plastic parts by injecting molten material into a mold. This technique is prevalent across multiple industries, including automotive, consumer electronics, medical devices, and packaging, due to its ability to mass-produce complex shapes with high precision and repeatability. The Process of Plastic Injection Molding The plastic injection molding process involves several critical steps: Clamping: The two halves of the mold are closed and held together under pressure by the clamping unit. Injection: Molten plastic, typically in the form of pellets, is heated until it becomes viscous and is then injected into the mold cavity under high pressure. Cooling: The plastic cools and solidifies into the shape of the mold cavity. Cooling time is crucial and depends on the thickness of the part. Ejection: Once the plastic has solidified, the mold opens, and the ...
