What We Do

Complete mold solutions
from concept to shipment

Every project begins with a conversation about your production goals. We then design, machine, test, and deliver tooling that performs — not just on paper, but on the floor.

Injection Mold Design

Custom injection molds built for volume, consistency, and longevity. We optimize gate placement, cooling channels, and ejection systems during design so your first shot is your best shot.

2D/3D CAD modeling
Mold flow analysis
Prototype to production

CNC Machining

3-, 4-, and 5-axis CNC milling and turning for complex mold components. Hardened steels, tool steels, aluminum — we machine to ±0.0005" on every part.

Multi-axis CNC centers
Hardened & exotic materials
High-precision grinding

Die & Fixture Fabrication

Stamping dies, forming fixtures, and assembly jigs engineered for your specific application. Built to withstand production environments and simplify your workflow.

Progressive & transfer dies
Custom fixturing
Weldment fabrication

Mold Repair & Maintenance

When production stops, every hour counts. We provide rapid mold repair, maintenance, and modification services to get your tools back in cycle with minimal downtime.

Emergency repair response
Preventive maintenance
Tool modification & rework

Technical Capabilities

Quality isn't an inspection step — it's a habit we built 40 years ago, and it's the reason our molds last for millions of cycles.
