JIGS · FIXTURES MECHANISM PARTS 3 & 5-AXIS CNC
From single-piece test fixtures to 500-unit production jig sets — IDMockup manufactures precision mechanism parts, custom jigs, and complex assembly tooling for mechanical engineers across Singapore, Taiwan, Japan, and Thailand. ±0.05mm. 24-hour quotation.
Mechanical engineers waste weeks on wrong-tolerance vendor hand-offs
You know the problem: tight-tolerance jigs quoted at ±0.1mm end up with chip-fit errors. Test fixtures arrive without datum verification. Mechanism parts look right on paper but bind on assembly. IDMockup builds precision mechanical components to the spec you define — with CMM proof.
Most CNC shops quote jig bodies to ±0.05–0.1mm. For precision machining jigs where the locating bushings must repeat within 5μm, this tolerance stack invalidates every subsequent operation. The first batch reveals the error. 3-week rework cycle starts.
Ground and honed jig bodies — hardened steel locating bushings to H7/p6 fit
Jig frames in AL7075 or hardened 45# steel, with ground reference datums. Replaceable hardened bushings pressed to H7/p6 or H7/g6 fits. Every jig CMM-verified to ASME Y14.5 before shipment. Full datum-to-datum dimensional report included.

ISSUE · 02⚠ The Problem
Test fixtures with no electrical continuity path — cable routing impossible
PCB test fixtures often arrive with no provision for probe pin housings, cable channel routing, or locking bar pivot points. The test engineer has to re-drill, tap, and reposition — invalidating the datum reference frame. Costly for high-precision 5G RF test stations.
Full electrical integration review — probe pin housings, cable channels, and locking pivots CNC-machined in
IDMockup DFM reviews test fixture CAD for probe pin pocket depths, spring plunger clearances, cable routing channels, and PCB datum locators before machining begins. Probe housings are reamed to H6 fit. Pivot pins in SUS440C. Co-planarity checked on granite surface plate.
Complex mechanism parts require 5 setups — each compounds positional error
A multi-feature mechanism part with bores on 3 faces, compound-angle pockets, and thread-on-diameter features typically needs 4–6 setups on a 3-axis machine. Positional error compounds at each setup. The 6th bore is off 0.2mm from design intent. Assembly doesn’t close.
IDMockup’s 5-axis CNC centres complete multi-face parts in one or two setups. All bores, pockets, and angled features cut from a single datum. No setup-to-setup accumulation. Typical positional accuracy: ±0.05mm part-to-datum. Full CMM verification with FAI package.

Make your design precise – according to the “effect” you want to present, the “scenario” of use and the “product verification time”
In the product development process, rapid prototyping, test jigs, fixtures and the manufacture of functional components are the key bridges between design and actual mass production. These projects are not only “testing tools”, but also the basis for verifying whether the design can be implemented, which directly affects the efficiency and quality of product development.
At IDMockup , we know that every design carries the customer’s expectations for function, structure and usage scenarios. Therefore, we provide high-efficiency and high-precision proofing and mechanism manufacturing services, from single samples to small-scale production, which can be completed quickly and meet actual application needs. We can tailor practical and stable mechanism parts and test fixtures according to the “functional effects”, “usage environment conditions” and “product verification cycle” that customers want to present, helping you accelerate the development schedule and improve design precision.
Make every test closer to actual use, and make every proof closer to mass production standards. IDMockup uses efficiency and quality to help you shorten the verification schedule and achieve design accuracy.
IDMockup’s production features in the product verification stage
☑️Selected workmanship to ensure durability and stability : According to the usage scenario and verification requirements, the most suitable processing technology and materials are selected to ensure that the sample has sufficient durability and structural stability to truly withstand actual testing
☑️Strict tolerance control to improve dimensional accuracy : Pay attention to the precision of each mechanism component, strictly control the tolerance of key mating surfaces and structural parts, and improve assembly smoothness and product consistency
☑️Appearance details to fully present the design intent : From spraying, polishing, transparent processing to surface texture, the appearance effect is carefully processed to make the sample not only practical, but also accurately convey the product image during the verification and display stages
What production skills does IDMockup have in the product verification stage?
CNC machining tools have high precision and stability, and can quickly produce mechanical parts, jigs and fixtures that meet design requirements, accelerating the proofing and verification process.
3D printing can quickly produce complex structures and shorten the proofing time. It is suitable for the initial verification of test jigs, fixtures and functional parts, and accelerates the product development process.
Silicone mold making is suitable for replicating precision parts in small quantities. It can quickly produce sample parts and mechanical parts with consistent appearance, reduce mold opening costs and shorten development time.
Appearance processing improves the texture and recognition of samples, can simulate the final product effect, facilitate display and verification, and make rapid proofing and fixture production closer to actual usage scenarios.
