RAPID PROTOYPING

Accelerating Product Development with Precision

High-Precision CNC Machining – Rapid milling and turning of prototype parts with tolerances as tight as 0.0001” (2 microns).
Wire EDM & Laser Cutting – Ideal for intricate geometries and ultra-fine features in metals, alloys, and thin materials.
Progressive Die Prototyping – Early-stage progressive die sample runs for functional testing before full-scale production.
In-Die Assembly & Testing – Integration of in-die tapping, contact insertions, and multi-metal prototypes.
Custom Tooling for Small Batch Runs – Dedicated tooling for low-volume prototype production that mirrors mass manufacturing.
Material Flexibility – Rapid prototyping using stainless steel, aluminum, copper, brass, titanium, and engineered alloys.
Comprehensive Design Support – Design for Manufacturability (DFM) consulting to optimize prototypes for mass production.
Functional & Mechanical Testing – Ensuring prototypes meet GD&T, fit, form, and function requirements.
