What is Plastic Injection Molding?

Injection molding is the most cost-effective way to manufacture plastic parts at scale. The plastic injection molding process involves pouring molten plastic into a custom-made mold. Once it’s hardened, you have your plastic part.

It’s the ideal way to produce high volumes of virtually identical plastic parts. Tolerances are small, repeatability is high, and costs are low thanks to using a single mold for thousands of parts.

Injection molding is also extremely versatile. It boasts a wide variety of materials, surface finishes, and colors.

Our Injection Molding Procedure - Step by Step

1. Get a FREE Quote

It’s easy to request a quote online. Our team will respond within 1 business day with more information on our injection molding services USA.

2. Detailed DFM Report

We’ll provide you with a detailed DFM report including our feedback and advice on your plans. When your part is approved by both yourself and us, we’ll move onto the plastic injection molding process.

3. Mold Flow Analysis & Design

Our mold flow analysis studies how the molten plastic is likely to move through your mold. Once we’re satisfied that mold flow is optimal, we’ll create a precision mold based on your product requirements.

4. Mold Tooling Production

We use top-quality materials in our production tool. This ensures that our final mold is as closely tailored to your specifications as possible. We can do aluminum tooling for market validation before moving into steel tooling for a full-scale production run.

5. T1 Sample Delivery

We’ll send you a T1 prototype to inspect. If you need changes, we’ll go back and adjust the mold at this point. Once you approve the T1 sample, we’ll move into the injection mold production process.

6. Low-Volume Production Process

We create parts in a low-volume custom plastic injection molding process. This maximizes precision and saves you costs in the long run.

7. Quality Assessment

We ensure our parts meet international standards for tolerance and quality. We do rigorous quality control to make sure your parts are always compliant.

Injection Molding Process FAQs

Injection molding is used in a wide range of industries for its versatility and consistency. Some of the common applications include: 

  • Automotive Industry: Injection molding can produce complex vehicle parts with excellent repeatability. Car dashboards, bumpers, panels, light coverings, and door handles are perfect for injection molding. 
  • Aerospace Industry: Uses injection molding to mass-produce plastic components. Think turbine housings, panels, seats, and other lightweight parts. 
  • Medical Industry: Precision is essential in the medical field. Syringes, thermometer housings, small containers, and drip valves can be repeatedly produced with very little room for error.
  • Consumer Products: Any mass-produced plastic products can be easily manufactured using injection molding. Kitchen accessories, kids’ toys, cellphones, and more… The applications are endless and the injection mold process is cost-effective.

A well-made injection mold can last thousands to millions of cycles before needing repair or replacement. It depends on various factors, including mold quality, SPI rating, and maintenance of the mold.

The time it takes to design and create injection-molded parts depends on the project. Things that influence manufacturing time include: 

  • How complex the design is 
  • The design specifications 
  • How big the part is 
  • What surface finish it uses 
  • The quantity to make 

Complex designs need a longer production process than simple ones. Larger plastic components take longer to make than smaller ones. And high-volume orders will take more time than low-volume orders. Plastic injection molding companies will give you a detailed quote based on your specific needs.

Injection molding varies in production cost depending on the size and quantity of the part, the complexity of the project, the materials, and the surface finishes.
