What is Plastic Injection Molding?

Injection molding is a manufacturing process that consists of filling a metal mold cavity with liquid plastic resin, which then cools and forms a plastic part.

It’s most often used for the manufacturing plastic parts at scale due to its low material waste and low cost per part. It’s an ideal manufacturing process for industries like medical devices, consumer products, and automotive.

Our plastic injection molding process produces custom prototypes and end-use production parts with lead times as fast as 1 day. We use aluminum molds that offer cost-efficient tooling and accelerated manufacturing cycles, and stock about 200 different thermoplastic resins.

Common applications for plastic injection molding:

  • low-volume production
  • bridge tooling
  • pilot runs
  • functional testing and prototyping

The key steps in injection molding:

  • Clamping: The mold’s two sides are sealed shut under hydraulic pressure. 
  • Screw Recovery: Plastic material is fed into the barrel and conveyed via rotating screw down the barrel toward the front of the screw.  As the material is conveyed it is heated to the specified melt temperature creating the “shot” or volume of material to be injected. 
  • Injection: Screw is pushed forward injecting the material under very high pressure into the mold. 
  • Cooling: Water circulated through channels in the mold to remove heat and solidifies the molded part.
  • Ejection: The clamp releases, mold opens and part is ejected from the mold.

DTG Plastic Injection Molding Manufacturer Process

Our custom plastic injection molding services are perfect for industries ranging from automotive and medical to consumer goods and electronics. Whether you need small, intricate parts or large, complex components, we have the capabilities to deliver.


Material Selection

Choosing the appropriate plastic material is the initial step. This involves consideration of factors such as the product’s intended use, environmental conditions, durability, and cost. The selected material impacts the performance, lifespan, and functionality of the final product.


Mold Creation

The next step involves designing and creating the mold based on the product specifications. High-quality stainless steel is often used due to its durability and resistance to wear. The mold’s design is guided by the SPI-SPE standards, ensuring precision and consistency in the produced parts.


Injection Process

The selected plastic material is heated and injected into the mold under high pressure. This stage requires careful control of conditions like temperature, pressure, and injection speed to ensure the material fills the mold uniformly and solidifies correctly, maintaining the design’s integrity.


Cooling & Ejection

After injection, the mold is cooled to allow the plastic to harden into the desired shape. Once adequately cooled, the final product is ejected from the mold. This step includes any necessary post-processing services such as trimming, surface finishing, and assembly to ensure the product meets all specifications and quality standards.
