Finishes for Plastic Injection Molding
We offer a wide range of surface finish options for plastic injection molded parts, enhancing both functionality and aesthetics.
The natural surface finish directly from the mold, reflecting mold quality and material characteristics.
Standardized surface finishes defined by SPI grades, controlling texture, gloss level, and appearance consistency.
Smooth, refined surfaces achieved through mold or part polishing for improved aesthetics and reduced friction.
Applies logos, symbols, or graphics onto flat plastic surfaces with durable and consistent ink coverage.
Transfers detailed graphics onto curved or irregular plastic surfaces with high precision and repeatability.
High-shine surface finish offering enhanced visual appeal, commonly used for consumer and display components.
Low-gloss surface finish that reduces reflections, improves grip, and minimizes visible fingerprints.
Adds color, protection, or functional coatings to injection molded parts for enhanced appearance and performance.
Creates textured or patterned surfaces through chemical or mold-based etching for improved aesthetics or grip.
Uses laser technology to permanently mark text, logos, or codes onto plastic part surfaces.

Plastic Injection Molding FAQs
Plastic injection molding is a manufacturing process where melted plastic is injected into a mold cavity to form precise parts. It is widely used for high-volume production of complex and consistent components across various industries.
- Plastic Mold Design
Engineers design the mold based on product requirements, material selection, and manufacturability considerations to ensure quality and efficiency.
- Injection Mold Making
The mold is manufactured using CNC machining, EDM, and polishing, achieving the required precision and surface finish.
- Plastic Molding Production
Molten plastic is injected into the mold using injection molding machines, cooled, and ejected to form the desired part.
- Parts Post-Processing
Finished parts may undergo trimming, polishing, printing, painting, or other surface treatments to meet functional or aesthetic requirements.
Plastic injection molding is ideal for high-volume production, complex geometries, tight tolerances, and parts requiring consistent quality. It is cost-effective for both prototypes and mass production when precision and repeatability are critical.
Plastic pellets are heated until molten, then injected under high pressure into a mold cavity. After cooling, the mold opens, and the solidified part is ejected. This process allows rapid production of precise and uniform plastic parts.
Costs are influenced by factors including mold complexity, part size and geometry, production volume, material selection, cycle time, and required surface finish or post-processing. Efficient design and material choice can help optimize cost.
