Injection Molding
Prototypes are essential in product development. They help turn ideas into physical products that you can test, improve, and present to your customers or investors. A good prototype reduces the risk of errors in mass production and helps save time and cost.
From file optimization (STL/STEP) to post-processing (sanding, painting, assembly), we handle every detail. Our engineers provide free DFM feedback to save you cost and time.
72-hour standard delivery for 3D printing & CNC. Expedited options available. We know time-to-market is critical.
Every prototype undergoes rigorous dimensional checks (CMM & manual) and material certifications. ISO 9001:2015 compliant processes.
Start with 1 prototype and scale seamlessly to low-volume production. One partner, infinite possibilities.
· Automotive & Aerospace: Functional testing, lightweighting
· Medical & Dental: Biocompatible prototypes, FDA-grade materials
· Consumer Electronics: Housings, ergonomic validation
· Industrial Equipment: High-strength, heat-resistant components
