MATERIALS
Injection Molding materials
We offer a wide range of injection molding materials to support projects from simple prototypes to complex, high-volume production.
ABS
Tough, impact-resistant, and easy to mold. The go-to for enclosures, housings, and consumer products.
Polycarbonate (PC)
High impact strength and optical clarity for lenses, guards, and parts that can't afford to crack.
TPU / TPE Elastomers
Rubber-like flexibility for grips, seals, gaskets, and soft-touch overmolds in a range of durometers.
Nylon (PA6 / PA66)
Excellent wear resistance and strength, ideal for gears, bushings, clips, and structural parts. Available glass-filled.
Polypropylene (PP)
Chemical resistance, living hinges, and low cost. The workhorse for containers, caps, and high-volume parts.
Acetal (POM / Delrin)
Low friction, high stiffness, and dimensional stability for precision moving parts and mechanisms.

SERVICES
Plastic Injection Molding services
We offer a wide range of injection molding services to support projects from simple prototypes to complex, high-volume production. Explore our specialized services below.
Injection Mold Tooling
From rapid tooling to full-scale production molds, we offer fast, cost-effective tooling solutions tailored to your part geometry and volume requirements. Our molds are built for durability, repeatability, and precision.
Overmolding
Combine multiple materials into a single component through precision overmolding. This process is ideal for creating parts with enhanced grip, cushioning, or integrated soft-touch features.
Insert Molding
Integrate metal or threaded inserts directly into molded plastic components for added strength and functionality. Ideal for electronics, fasteners, and parts requiring reinforced load points.

FAQ
Questions, answered
Have a question that is not answered here? Contact our engineering team directly and we will get back to you quickly.
What file types do you accept?
We accept major 3D CAD formats, including STEP, IGES, SolidWorks, Parasolid, and STL. PDF and DXF drawings are also helpful for communicating dimensions, tolerances, materials, and finish requirements.
How fast can parts be made?
Timing depends on the process, material, quantity, and complexity of your parts. Quotes are typically provided within 24 hours. Prototype orders may be completed in as little as 1 to 10 business days, while larger production orders may require additional time.
Can you hold tight tolerances?
Yes. We can hold tolerances as tight as ±0.001 inch on critical features when the material, geometry, and manufacturing process allow it. Include a drawing with your CAD files so our engineering team can review each tolerance requirement.
What industries do you serve?
We support customers across automotive, industrial equipment, consumer products, product development, and other industries that require dependable custom parts. Contact us to discuss the requirements for your application.
Do you offer surface finishing services?
Yes. Available finishes include anodizing, powder coating, plating, polishing, and other options based on the material and manufacturing process. Tell us your appearance and performance requirements when requesting a quote.
What happens after I submit a quote request?
Our engineering team reviews your files, material, quantity, tolerances, and finish requirements. We will contact you if we have questions, then provide clear pricing, estimated timing, and the next steps for production.
