With our developed manufacturing capacity, we will be able to produce high-precision metal and plastic parts, which produce the same level of consistency in the quality of prototypes, tooling, and full production. Having started with multi-axis milling, Yicen Precision has ensured reliability in the results even with most complex geometries, in terms of turning and development of the fixtures.
CNC milling is a subtractive machining technique which involves cutting metal and plastic material in the form of precise and repeatable shapes using 3-axis, 4-axis and 5-axis machines. Best suited to complicated geometries, strict tolerances, and high surface finishes on prototype and production components.

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.
Can fixtures wear out or lose accuracy over time? How do you prevent this?
Yes. Continuous use introduces:
To prevent accuracy loss, we design fixtures with:
Can custom fixtures reduce cycle time and production cost?
Absolutely. Fixtures directly improve efficiency by:
Over large production volumes, fixtures often deliver significant cost savings per part.
Which industries benefit most from jig & fixture design?
Our fixtures serve:
These sectors rely on tight tolerances, repeatability, and process stability.
Are custom fixtures useful for low-volume or prototype work?
Yes, when:
Lightweight or 3D-printed prototype fixtures can also be used for early stages.
What design standards ensure a fixture is accurate and safe to use?
A well-engineered fixture follows:
These best practices ensure accuracy, operator safety, and long-term stability.
