Introduction to Custom Injection
Custom injection molding is a highly versatile manufacturing process used to produce plastic parts in large quantities. It involves injecting molten plastic material into a custom - designed mold cavity, where it cools and solidifies to take the shape of the mold. This process is favored for its ability to create complex geometries with high precision, repeatability, and relatively low cost per unit for large production runs. Custom injection molding can be used across various industries, including automotive, medical, consumer goods, electronics, and more.
