Fabrication Capabilities and Services
At DureX, we don’t just cut metal — we shape ideas into real-world solutions. Our advanced fabrication services utilize various sheet metal fabrication processes and manufacturing methods to combine speed, precision, and flexibility, meeting tight tolerances and complex geometries across a wide range of industries. Whether you need a one-off prototype or full-volume production, we have the tools and team to deliver.
Our Core Fabrication Services Include:
Laser Cutting Using focused laser beams and plasma cutting, we cut precise contours in steel, aluminum, and other metals — ideal for both intricate designs and high-speed production. Capable of handling material thicknesses from 0.024” to 0.250” and beyond.
Turret Punching Automated punching for creating detailed perforations, louvers, tabs, and cutouts — perfect for sheet metal parts in electronics and enclosures.
Press Brake Forming & Bending CNC-controlled press brakes create consistent bends and complex shapes. We use European-style tooling for tighter tolerances and faster repeatability.
Welding & Assembly We offer MIG, TIG, and spot welding, along with hardware insertion and light assembly to deliver finished or semi-finished components.
Finishing Services From powder coating to chromate conversion, we apply finishes that enhance durability, aesthetics, and performance.
With our AMADA CNC laser and turret press systems, we handle small-batch production (under 15,000 units) efficiently and cost-effectively — ideal for companies scaling up or requiring frequent design changes.
All fabrication work is done at our Union, NJ facility, serving businesses across New Jersey and the Tri-State Area.
Prototyping to Production – Scalable Manufacturing
Whether you’re building a single prototype or preparing for a high-volume rollout, DureX offers the flexibility to scale at every stage. Our sheet metal fabrication process is optimized for both prototyping and high-volume production, with infinite capacity to handle any order size. This ensures timely shipments and the confidence to grow without switching suppliers.
Start Small. Scale Fast.
We understand that production volumes often start small. That’s why we specialize in low-volume prototypes, offering fast turnaround times without the burden of high upfront tooling costs. Using flexible fabrication methods like laser cutting and turret punching, we help bring your concept to the desired shape quickly and affordably.
As demand increases, we guide your transition to cost-saving production methods, including:
Hard Tooling & Progressive Dies for large production runs
Hybrid Tooling to combine fabrication speed with forming efficiency
Staged Tooling Systems for high-throughput part manufacturing
These transitions are planned with ROI in mind — allowing you to achieve substantial cost reductions as volumes rise.
Example:
A client producing a metal chassis and cover reduced part costs from $22 to $14 per unit by moving from soft tooling to hard tooling. At 3,000+ units/month, the $80K tooling investment paid for itself in under four months.
Our Union, NJ facility supports businesses at every stage — from startup prototypes to nationwide production.
