Custom Precision Components
Tuguan Semiconductor’s core business is drawing-based custom fabrication. Most semiconductor process components are application-specific — we manufacture to your engineering drawings, CAD files, or physical samples.
How to Order Custom Parts
Option A — Engineering Drawing
Submit a 2D drawing (PDF, DWG, DXF) with:
- All critical dimensions and tolerances
- Surface finish requirements (Ra or equivalent)
- Material specification (grade, purity)
- Any special inspection or documentation requirements, such as leak testing, material analysis, or crystal-orientation review
Our team will review the drawing and follow up with quotation details, manufacturability notes, and estimated lead time based on scope.
Option B — CAD File (3D Model)
Submit a STEP or IGES 3D model. Our engineers extract a 2D working drawing for your approval before production begins.
Option C — Reverse Engineering (Physical Sample)
Send a worn or broken component for measurement. We will:
- Review critical dimensions using the appropriate measurement method
- Identify material by available records, visual inspection, or arranged analysis when required
- Generate a 2D drawing for your approval
- Manufacture replacement parts after geometry and material requirements are confirmed
Design for Manufacturability Support
Our application engineers can advise on:
| Topic | Guidance |
|---|---|
| Tolerance assignment | Which tolerances are achievable vs. unnecessarily tight |
| Wall thickness minimums | Structural limits for drilling and thin-wall sections |
| Corner radii | Minimum achievable internal radii |
| Surface finish requirements | What Ra is actually needed for each surface |
| Material selection | Which grade offers the best performance/cost trade-off |
This service is free — we prefer to get the design right before production begins.

Lead Time Factors
Lead time depends on drawing complexity, material availability, quantity, processing steps, and inspection requirements. Prototype and batch orders are reviewed after drawings, samples, or specifications are received.
Quality Documentation
Documentation can be discussed based on order requirements and may include:
- Dimensional inspection records for agreed critical features
- Material certificates depending on material source and order scope
- Certificate of conformance or project-specific quality documents when applicable
- Additional QC requirements specified at order placement
