AI Hardware & Semiconductor Equipment Prototyping
As custom AI chips and server supply chains scale up, the mechanical hardware around them — heat sinks, enclosures, brackets, and test fixtures — needs to be validated just as fast. JIERCHEN CNC-machines and SLA-prints the periphery hardware that AI hardware and semiconductor-equipment teams need to test fit, thermal, and function before committing to production tooling.
We prototype the mechanical periphery — fixtures, thermal hardware, enclosures, and validation models — not semiconductor fabrication itself.

We build the mechanical parts that surround AI accelerators, custom silicon, and server infrastructure — not the chips or the fab equipment themselves.
Heat Sink Bases
CNC-machined aluminum heat sink bases and cold-plate bodies for AI accelerator and GPU thermal validation, machined from AL 6061 or AL 7075.
Liquid-Cooling Module Enclosures
Housings and manifolds for liquid-cooling modules, prototyped to check fit, port alignment, and seal clearance before tooling.
Test Fixtures, Assembly Jigs & PCB Carriers
Fixtures that hold boards and modules in a fixed position for functional test, plus PCB mounting brackets and carriers for server assembly.
Transparent Flow-Path Models
SLA-printed clear models of coolant flow paths and manifolds, built to visually verify flow routing before committing to metal.
Trade-Show Cutaway & Functional Demo Models
Section-cut and working demo models that show internal cooling or chip-carrier layouts on the show floor.
Server Chassis & Rack Mechanical Parts
Chassis panels, rack brackets, and structural mechanical components for server and rack-scale hardware.
Process Guide: Matching the Method to the Part
| Process | What it produces | Typical AI-hardware parts |
|---|---|---|
| CNC machining (AL 6061 / AL 7075) | Structural and thermal-conductive metal parts, ±0.01mm on critical dimensions, ISO 2768-f general tolerance | Heat sink bases, cold plates, chassis panels, PCB mounting brackets |
| SLA (stereolithography) | Optically clear or fine-detail resin parts | Transparent flow-path models, coolant-routing mockups, cutaway demo models |
| Surface treatment | Anodizing, bead blasting, and polishing for corrosion resistance, emissivity, or cosmetic finish | Heat sink bases, enclosure panels, show-floor demo models |
| CMM inspection | Dimensional verification against your CAD model | Fixtures, brackets, and enclosure mating features before you sign off on the design |
From Fixture Design to Quality-Verified Parts
Test fixtures and assembly jigs for board-level and module-level validation are one of our most requested builds for AI hardware programs — see our dedicated fixture and jig prototyping page for design approach and materials. Every part, whether it’s a heat sink base or a test fixture, goes through the same quality control process: CMM-verified critical dimensions, ISO 2768-f general tolerances, and inspection records you can review before the part ships.
Need a mix of metal structural parts and plastic housings on the same build? Our plastic and metal prototyping service and in-house CNC and SLA equipment cover both in a single quote.
Building hardware for robots as well? The same structural, thermal and fixture parts show up constantly in robotics prototype manufacturing — robot links, joint prototypes, sensor mounts and end-effectors, supported from EVT and DVT builds through to pilot production.

Common Questions
What material and tolerance do you use for heat sink bases?
We CNC-machine heat sink bases from AL 6061 or AL 7075 aluminum, holding ±0.01mm on critical mating and mounting dimensions with ISO 2768-f general tolerances. We can add anodizing or bead blasting for corrosion resistance or emissivity, depending on the thermal application.
Can you sign an NDA and how do you handle our CAD files?
Yes, we sign NDAs before reviewing your design. CAD files are only used to quote and machine your part, and we do not share designs outside the project team. This applies to AI hardware and semiconductor-equipment programs the same way it applies to any other prototype.
Can you take a part from single-unit validation to a small batch?
Yes. Our four-stage process moves from SLA (Validate) to CNC (Test) to silicone or vacuum casting (Pilot) to steel-mold injection (Scale), so a single validation unit can move into a small pilot batch without starting over on a new supplier.
Need a Prototype for Your AI Hardware Program?
Send us the CAD file for your heat sink, enclosure, bracket, or fixture. We’ll quote within 24 hours and can sign an NDA before we open the file.
