Aerospace Injection Molding

Injection molding is ideal for making aerospace components from polymers. Bezels, lenses, air ducts and covers are just some of the parts that could benefit from the speed and consistency of the molding tooling and process. Making mold tools is a specialized aspect of injection molding, and it’s an area where prototyping services offer many benefits. As specialists in plastic injection molding, RevPart offers a range of services to help manufacturers bring new products to market in less time.

What Is Aerospace Plastic Injection Molding?

Plastics help aerospace manufacturers take weight out of their products. Modern engineering plastics in particular offer high strength and low density, making them invaluable in weight-sensitive applications.

Aerospace Parts Suitable for Plastic Injection Molding

  • Interior trim pieces: Bezels around display screens and lights, air inlets, seat backs and partitions
  • Exterior trim: Nonstructural parts such as covers, hubcaps and fairings
  • Structural components: Load-bearing brackets, wing and rudder components, and the airframe itself

Reasons for Choosing Injection or Silicone Molding

In molding processes, the mold cavity determines the final shape while injection speed and pressure determine the consistency between individual pieces. Other benefits of injection or silicone molding include:

  • Engineering capabilities: Injection or silicone molding offers the ability to incorporate other components into the mold, such as bushings or screw retainers. This is a technique referred to as overmolding.
  • Design flexibility: With injection molding, you have more control over surface texture, finish and appearance.
  • Fast and cost-effective: Injection molding machines operate on short cycle times and the parts produced typically require minimal finishing.

The Role of Plastic Injection Molding and Prototyping

Prototype parts are essential for validating product designs. Some prototypes enable verification of fit and finish while others are needed for functional testing. While dimensionally accurate pieces can be 3D printed or machined from a solid, these options typically lack the look, feel and mechanical properties of molded parts.

Injection molding and plastic part prototyping offer multiple advantages over the services that other aerospace additive manufacturing companies provide, including:

  • Better testing: Get parts made in the actual grades of material specified by the design team that are ready to test.
  • Sleeker appearance: Molded parts have the required surface finish and appearance.
  • No resolution limitations: Many additive techniques have clear layering that affect the appearance and possibly the function of a component, whereas injection molding does not.
