Quality American plastic injection molding manufacturers
Injection molding enables manufacturers to cost-effectively produce plastic products in large volume via a highly repeatable and predictable production process with low scrap rates.
During injection molding, the raw material is pushed into a mold at a high pressure, which shapes the plastic into the desired shape and size. Because of its ability to produce high volume and consistent quality, injection molding is the most commonly used manufacturing process for producing solid plastic parts. However, it has high design and tooling costs so it is best used when you need plastic parts in high volume.
