Drilling jigs and fixtures ensure concentricity, precision hole spacing, and long-term accuracy in repetitive machining.
Our engineering approach focuses on accuracy, manufacturability, and real production performance—not theoretical design. Every fixture is built to support tight tolerance control, stable alignment, and repeatable operations in demanding industrial environments.
Specialists in machining, welding, assembly, BIW tooling, and GD&T-critical fixture design, with deep understanding of locating schemes and process constraints.
Design and manufacturing workflows follow ISO 9001:2015, AS9100D, and ISO 13485 quality standards to ensure consistency and traceability.
FEA and kinematic simulation are used to evaluate deflection, stress, clamp forces, and repeatability before fabrication begins.
Optimized workflows allow quick concept iterations, 3D modeling, and prototype fixture builds without compromising precision.
In-house CNC machining, fabrication, EDM, and finishing reduce lead time, improve part consistency, and avoid outsourcing delays.
From initial requirements to engineering validation, final assembly, and on-site integration, we handle the complete fixture lifecycle.
Custom jig and fixture tooling delivers measurable performance improvements by removing variability and stabilizing your manufacturing process.

What materials and processes are used to manufacture high-quality fixtures?
Common materials include:
Manufacturing processes include:
How do I choose between CNC-machined, welded, or 3D-printed fixtures?
What is the difference between a jig and a fixture?
A jig guides the cutting or drilling tool to the correct location.
A fixture securely holds and locates the workpiece during machining, welding, or assembly but does not guide the tool.
Use a jig when tool path accuracy is essential; use a fixture when part stability and repeatability are the priority.
When should I use a custom fixture instead of standard work-holding?
Choose a custom fixture when you need:
Standard vises and clamps cannot maintain the same datum accuracy or long-term consistency as a custom fixture.
How does fixture design improve repeatability and reduce operator error?
Custom fixtures define fixed datums, locator points, clamp positions, and engagement surfaces, so every part sits exactly the same way for every cycle.
This eliminates:
The result is predictable accuracy and fewer production defects.
We specialize in converting your ideas into high-quality, functional components with unparalleled speed and accuracy. With advanced technology and expert craftsmanship, we create parts that meet the most complex specifications.
