Surface Treatments for Plastic Injection Molded Parts: Finishing Options & Specifications
Draft angle requirements vary depending on the selected surface finish. We also offer industry-standard Mold-Tech finishes to meet your cosmetic and functional needs for custom plastic injection molded parts.
| Finish | Description |
|---|---|
| PM-F0 | Non-cosmetic finish; final appearance determined at Protolabs’ discretion, ideal for internal components |
| PM-F1 | Low-cosmetic finish; most tool marks are removed, suitable for non-visible functional parts |
| PM-F2 | Non-cosmetic finish; EDM (Electrical Discharge Machining) marks are permissible, cost-effective for structural components |
| SPI-C1 | 600 grit stone finish; surface roughness of 10–12 Ra, a standard semi-cosmetic option |
| PM-T1 | SPI-C1 base finish + light bead blast; creates a matte, textured appearance |
| PM-T2 | SPI-C1 base finish + medium bead blast; provides a more pronounced textured surface |
| SPI-B1 | 600 grit paper finish; precise surface roughness of 2–3 Ra, for improved cosmetic appearance |
| SPI-A2 | Grade #2 diamond buff finish; ultra-smooth surface with 1–2 Ra roughness, ideal for high-cosmetic applications |
How Does Plastic Injection Molding Work?
Plastic injection molding is a high-volume manufacturing process that melts plastic resin and injects it into a custom mold cavity under high pressure. Once cooled and solidified, the mold opens to eject the finished plastic part.
Step-by-Step Working Process
Plastic Resin Feeding
Raw plastic pellets are fed into the injection molding machine's hopper.
Melting & Plasticizing
The pellets are heated and melted into a molten, flowable plastic inside the barrel.
Injection
The molten plastic is injected at high pressure into a closed, precision mold.
Holding & Cooling
Pressure is maintained while the plastic cools and solidifies into the shape of the mold cavity.
Mold Opening
The mold opens, and ejector pins push out the completed plastic part.
Repeat
The continuous, highly automated cycle repeats for efficient mass production of identical parts.
Plastic Injection Molding Services for Custom Parts
Precision Aluminum &
We deliver high-quality custom aluminum and steel injection molds tailored to your production needs. Achieve tight tolerances down to 0.0008 in (0.02 mm) for consistent, repeatable parts. Our team provides free mold flow analysis to optimize design and reduce production costs. Ideal for high-volume manufacturing across industries.
Overmoulding Services | Durable Multi-Material Plastic Components
Overmoulding is a multi-step injection molding process that bonds plastic to a substrate (metal, plastic, or elastomer) to create integrated, long-lasting products. This technique enhances ergonomics, durability, and aesthetics, with flexible color and texture options. Perfect for grips, seals, and consumer electronics.
Insert Moulding Services | Encapsulated Components for Precision Parts
Insert moulding encapsulates metal or plastic inserts within a plastic part during injection, creating strong, single-piece assemblies. Ideal for designs with threads, holes, or embedded components, it eliminates secondary assembly steps and improves part strength. Commonly used for automotive, electronics, and medical devices.
