Yicen Precision specializes in custom jigs and fixtures designed for high-precision machining, welding, assembly, and inspection workflows.
Our jig and fixture design process ensures tight tolerances, repeatable accuracy, and stable part positioning across every production cycle.
Our jigs and fixtures improve accuracy, repeatability, and workflow efficiency across complex manufacturing environments.
Each design enhances stability, minimizes operator variation, and delivers consistent output in machining, welding, and inspection operations.
We engineer precision jigs and fixtures that support tight-tolerance machining, welding, and assembly operations.
Every fixture is built for rigidity, repeatability, and ergonomic usability — ensuring reliable performance in real production environments.
Built for stable clamping, heat control, and repeatable joint alignment in both robotic and manual welding setups.
Facilitate multi-step assemblies with accurate part orientation and ergonomic handling.
Provide precise GD&T verification, flatness, and dimensional checks — ideal for inspection jigs and fixtures.
High-rigidity BIW jigs and fixtures for frame and panel alignment in automotive production.
Custom locating and clamping devices designed for machining tolerances up to ±0.001″.
Drilling jigs and fixtures ensure concentricity, precision hole spacing, and long-term accuracy in repetitive machining.
Custom jig and fixture tooling delivers measurable performance improvements by removing variability and stabilizing your manufacturing process.
| Parameter | Specification |
|---|---|
| Improved Accuracy & Dimensional Control | Maintains fixed datums and consistent location. |
| Faster Cycle Times | Optimized layout reduces setups and increases throughput. |

Common materials include:
Manufacturing processes include:
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.
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.
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.
