Injektevormimine

Injektevormimine, often translated as injection molding, is a manufacturing process used to produce molded parts by injecting molten material into a mold. It is a high-volume production method widely employed for creating a vast array of plastic parts, from simple components to complex assemblies. The process begins with the melting of a thermoplastic or thermosetting polymer in a heated barrel. This molten material is then propelled by a reciprocating screw or a plunger into a precisely machined mold cavity. The mold is typically made of steel or aluminum and is designed to create the desired shape of the final product. Once inside the mold, the material cools and solidifies, taking on the form of the cavity. After a sufficient cooling period, the mold opens, and the finished part is ejected. The cycle then repeats. Injektevormimine offers several advantages, including high production rates, excellent repeatability, and the ability to create intricate designs with tight tolerances. However, the initial cost of mold tooling can be significant, making it most suitable for mass production. The process requires careful control of parameters such as temperature, pressure, and injection speed to ensure consistent part quality and to avoid defects like warping or sink marks.
