Plastic Injection Molding Capabilities
Fast and cost-effective process for creating aluminum or steel injection molds. Ideal for rapid prototyping needs or validating product concept for production.
Overmolding is a unique injection molding process that combines two or more components together. It is the best practice for the production of multi-color and multi-layers products.
Insert Molding is an injection molding process that encapsulates components in a plastic part. It is most commonly used for designs with threads and holes.
Liquid Silicone Rubber injection molding
Liquid silicone rubber (LSR) is a flexible injection molding process that produces elastic, durable parts. Get custom prototypes and production parts from 15 days.
Plastic Injection Molding Materials
Injection molding has the most variable options for materials, colors, and configurations when compared to CNC machining or 3D printing. Here are the materials RapidDirect provides for injection molding services.
Before injection molding process starts low or high-volume production, a high tolerance CNC machined tooling is needed. Most commonly used materials include:
Plastic injection molding service comes with a wide range of materials with different properties, including impact strength, rigidity, thermal resistance, chemical resistance, etc.
- Nylon (PA)
Additives and fibers
Standard plastic materials may not meet custom injection molding parts requirement. In this case, additives and fibers can be added to improve aesthetic and functional properties, providing additional features for your injection molded parts.
- UV absorbers
- Flame retardants
- Carbon fibers
- Glass fibers
Injection Molded Parts Surface Finishes
For most of the injection molded parts, no post-processing is needed. This is because the mold itself are usually finished to different levels and directly affect the surface finish of molded parts.
