Manufactured from Only the Highest Grade Plastics


Injection molding is a highly efficient and widely used manufacturing process that involves the
production of plastic parts and components by injecting molten plastic material into a mold cavity. This process has been employed by PowderPlast for the past 15 years.

Here’s how it works: First, plastic pellets or granules are heated until they liquefy, creating a molten plastic material. This material is then injected into a precision-engineered mold cavity under high pressure, which is typically shaped to match the desired part’s specifications. Once the plastic cools and solidifies within the mold, the mold is opened, and the finished product is ejected. Injection molding is renowned for its ability to produce complex, high-quality components with great accuracy and repeatability.


Its advantages include rapid production, low waste, and the ability to work with a wide range of plastic materials. It’s a cost-effective solution for large production runs and lends itself to customization through the use of different molds. Injection molding was the go-to choice for PowderPlast to create consistent and durable plastic products efficiently and to the highest standards.
