For your plastic injection molding needs, EPower Corp is considered one of the most dependable contract manufacturers in China. We serve American companies looking for high-quality, short lead times and competitive pricing.

In Simple Terms, What is Plastic Injection Molding?
Plastic injection molding is the process of melting plastic pellets into a molten fluid that is injected into a mold and cooled until the product is to the desired shape.


EPower Corp currently operates 15 plastic injection molding machines with the largest one being 550 tons (tool dimensions of approximately 36 in x 36 in). Our strong history of using high-quality tools combined with our strict management system gives us a quality and price advantage. 



Over the past 12 months, EPower's injection molding machine efficiency has increased by 13% making our process even more competitive.

With our tools being made in-house, we provide you with quick and safe tooling for your production needs. With these tooling capabilities, we can also offer design for manufacturing (DFM) and a wide range of tool design services. Our engineers are very efficient in designing a tool that will provide our client with the end product they need. When creating new tooling for our clients, we take the following into account:


  • Stress - Knowing how to design your tool to cushion the stress is key for the end product.

  • Gates - The location, type, and design all play a part with the appearance, removal, dimensions, and warping of the part.

  • Wall Thickness - The wall thickness depends on the type of resin that will be used and we know how to design this.

  • Sink Marks - Depending on the thickness, the part will cool at different rates which will cause rejections. We provide solutions to your sink mark issues.

  • Textures - Textures need to be taken into account on the CAD drawings. We know how to design textures on parts that will then be included in the tool.

  • Shrinkage - Shrinkage is a common theme with plastics. Knowing the shrinkage rate for each resin type is key to getting the correct product.
