Custom Prototype Molds – Built for Speed and Flexibility

Our prototype molds are designed for rapid production, which means you get your parts in days, not weeks. Every mold is custom-made to match your unique design, no matter how simple or complex.

Custom Structures: We support a wide range of part designs, including:

Snap fits and clips

Hinges and moving parts

Threaded caps and connectors

Hollow structures and internal channels

Multi-cavity layouts for faster testing

Fast Turnaround: We use aluminum or soft steel for rapid mold creation, perfect for testing and small batches.

Cost-Effective: No need for expensive production tooling—our prototype molds are affordable and made for quick validation.

Materials We Work With

We offer a wide selection of engineering-grade and test-friendly plastics, including:

ABS – Strong, easy to process, great for functional prototypes

PP (Polypropylene) – Lightweight and flexible, ideal for hinges and containers

PC (Polycarbonate) – Clear and tough for lenses or covers

PA (Nylon) – Durable and resistant to wear

TPE/TPU – Soft and flexible for grips and seals

HDPE, POM, PS, and more – Depending on your needs

We help you choose the right plastic based on your part’s usage, environment, and budget.

Injection Molding Process – How It Works

Our injection molding process is designed for speed, consistency, and accuracy:

Design Review: We check your 3D files and recommend the best molding approach

Tooling: We create a prototype mold using aluminum or soft steel

Injection: Heated plastic is injected into the mold cavity

Cooling & Ejection: Your part is formed, cooled, and ejected

Finishing & Inspection: Each part is checked for quality and function

This process is ideal for producing functional prototypes that closely match final production parts.

Beyond Prototypes – We Also Offer

Plastic Part Assembly: Need multiple parts assembled? We handle that too

Short-Run Production: Perfect for early market launch or investor samples

Modifications & Iterations: Quickly update your design and re-test

Spare Parts & Replacement Components: Great for aftermarket or low-volume needs
