Explore our injection molding services.

At Rapid-MFG, we understand the difficulty and pressure of product development. Working with a reliable injection molding manufacturer efficiently and professionally is important. Plastic injection molding is reliable and cost-effective, often used for high-volume c-product production and prototyping. Our injection molding services also include the following sub-functions:

Insert molding

Insert molding involves the injection of molten thermoplastic around a pre-placed insert to create strong, durable prototype parts.


Overmolding is a process in which multiple shots of thermoplastic are injected over or around a substrate to create highly customizable prototype parts.

Custom Plastic Injection Molding

Rapid-MFG focuses on production volumes of 1,000 to 100,000 parts or assemblies per year. For each production injection molding project, we work closely with our customers on production feasibility and advanced quality planning (AQP) to achieve reliable, high quality production.

Our Capabilities

Product Design

For each project, whether you send us a sample or a 2D file, we will work with you to improve all technical drawings, including 2D files and 3D files of the product.

Mold Design

Mold design is the most important part of the whole mold making process because it determines the life of the mold. All molds are subject to mold flow analysis to prevent errors.

Mold Making

Our mold making process starts from analyzing steel. This is an essential procedure to make sure the density of steel, so that all FOW injection molds meet the FOW standard. All parts are machined by high precision specialty machines like CNC Machine, Drilling Machine, Wire Cutting Machine, EDM, Lathing Machine, Engraving Machine.

Injetion Molding

From prototype, to pilot, to production parts, FOW injection company combines the latest Injection molding processes with proprietary technology and an experienced Injection Molding manufacturing team to deliver high quality, on-demand injection molded parts.

Surface Finishes of Injection Molding

Injection molding includes injection mold tooling, plastic injection molding, and more. The surface treatment of the mold is usually completed during the production process. After the injection molding is completed, we will carry out certain surface treatments on the finished product as per your requirement.

 GlossyA grade finishes are made using a diamond buffing process and yield shiny and glossy surfaces on injection molded parts.Learn More>>


B grade finishes use grit sandpaper to produce parts with a slightly rougher finish than grade A parts. Custom molded plastic parts that undergo B grade finishing have a matte surface texture.

Learn More>>

 MatteC grade finishes use grit sanding stones to produce a rough, uneven surface. Injection plastic parts that undergo C grade finishing have a matte surface texture.Learn More>>
 TexturedD grade finishes use grit and dry glass beads or oxide to produce a very rough textured finish. Depending on the type of material used, products can have a satin or dull finish.
