Can You Manufacture Custom Sizes and Shapes from 2D/3D Drawings?
Yes. Shih Yeh can review customer-supplied 2D and 3D drawings for custom sizes, profiles, curved surfaces, hole locations, bending, deep drawing, welding, CNC machining, tube bending, and surface finishing. Manufacturability is confirmed according to the intended use, installation location, material, thickness, tolerances, cosmetic requirements, and estimated volume.
Accepted Drawing Formats
| File Type | Accepted Formats | Primary Purpose |
|---|---|---|
| 2D Drawings | PDF, DWG, DXF | Dimensions, tolerances, material, hole locations, surface finish, and inspection requirements |
| 3D Models | STEP, STP, IGES, SolidWorks | Geometry, curved surfaces, forming depth, and structural relationships |
A preliminary review can begin with only a 2D drawing or only a 3D file. Missing dimensions, tolerances, and technical requirements can be confirmed before formal development.
Materials and Processes That Can Be Evaluated
Shih Yeh has manufacturing experience with aluminum alloys, stainless steel, hot-rolled steel, cold-rolled steel, and copper. Depending on the part design, the following processes can be reviewed:
● Stamping, deep drawing, and local forming
● CNC machining, welding, and assembly
● Polishing and surface treatment
● Tube bending and forming
The final process route is confirmed according to the drawing and project requirements.
What Is Reviewed for Manufacturability?
- Whether tolerances match functional and production needs
- Whether forming may cause cracking, wrinkling, springback, or distortion
- Whether the material is suitable for welding, polishing, and surface finishing
- Whether critical cosmetic surfaces can remain consistent after forming and machining
- Whether tooling, equipment, inspection methods, and expected volume are suitable for production
Typical Project Flow
- Submit drawings and basic requirements
- Manufacturability review
- Confirm material, critical dimensions, cosmetic and test requirements
- Tooling, sampling, and sample submission
- Pilot run, customer approval, and stable mass production
The actual development route and timeline depend on product complexity, tooling needs, testing, and the customer
approval process.
Can We Start with a Concept Drawing?
Yes. Existing design information can be used for an initial discussion. For a more accurate preliminary review, please provide at least:
● Intended product use and actual installation location
● Estimated dimensions and material
● Assembly method and main cosmetic requirements
● Estimated order volume and expected development schedule
Complete 2D/3D drawings and technical specifications will still be required before formal quotation or tooling release.
Recommended Information to Submit
- 2D drawing and 3D model
- Intended product use and installation location
- Material, sheet thickness, or tube specification
- Overall dimensions, critical dimensions, and tolerances
- Hole positions, assembly, welding, or joining requirements
- Surface finish, cosmetic standard, and test requirements
- Prototype quantity, order quantity, and annual demand
- Packaging, export destination, and expected schedule
Do You Have a Custom Part with Special Sizes or Multiple Processes?
Submit PDF, DWG, DXF, STEP, STP, IGES, or SolidWorks files. Shih Yeh can review the material, geometry, tolerances, intended use, installation location, cosmetic requirements, and estimated volume to evaluate manufacturability and plan sampling, pilot production, and mass production.
