Injection Molding

Your Go-To Source for Injection Molding

We cater to both small runs and large-scale production, with lead times starting at 5-10 days for standard parts and 10-20 days for custom molds, depending on complexity.

Plastic Injection Molding

Forces molten plastic into steel molds under high pressure to mass-produce identical parts with fine details.

Rapid Tooling

Fabricates short-run production molds in days instead of weeks for prototyping or bridge manufacturing.

Optimized Production Planning for Large-Scale Molding

Before production, we plan every detail—mold durability, batch consistency, and cost efficiency—to maximize your return on investment.

Surface Finish Options

Protecting and Optimizing
Your Precision Parts

Newly formed cnc parts require specific post-processing to boost durability, improve surface aesthetics, and allow for color variation. We offer 13 unique surface treatments designed for optimal part outcomes.

As Machined

Leaves parts with their natural, economic finish directly from machining.

Brushed Finishing

Creates a uniform, textured matte appearance for enhanced aesthetics.

Sand Blasting

Produces a clean, diffuse matte surface, ideal for improved paint adhesion.

Anodizing Type II

Forms a decorative, corrosion-resistant, and dyeable oxide layer on aluminum.

Anodizing Type III

Builds a harder, thicker, and more wear-resistant protective coating than Type II.

Heat Treatment

Alters metal properties like hardness and strength through controlled heating and cooling.

Polishing

Achieves a smooth, highly reflective surface, eliminating imperfections for visual appeal.

Electro Plating

Deposits a thin metal layer to boost corrosion resistance, conductivity, or visual appeal.

Painting

Applies a colored, protective coating, customizable in various textures and finishes.

Passivation

Enhances stainless steel’s corrosion resistance by forming a stable, protective oxide film.

Electrophoresis

Ensures even and highly adherent paint coverage, especially on complex geometries.

Alodine Finish

Provides corrosion protection and electrical conductivity, often as a paint primer for aluminum.

Teflon Coating

Offers excellent non-stick, low-friction, and high-temperature resistance properties.

Gold Plating

Delivers superior conductivity and oxidation resistance, commonly for electronic applications.

SPI Surface

Defines precise mold textures, from mirror-like to coarse, for injection molded parts.

Vibrant & Durable Aluminum Anodizing

Permanent color and durable protection for aluminum that enhances beauty and is built to last.
