This design guide was created to address the challenges many designers face in understanding manufacturing feasibility and controlling product costs.
We recommend customers follow the modeling guidelines outlined in this chapter to fully benefit from features like instantaneous cost estimation, automatic feasibility assessment (whether the design can be quoted automatically), faster lead times, and improved quality and service.
Chamfers Larger Than C0.5 Require Modeling
For sections without chamfers or those with chamfers of C0.5 or smaller in default 3D models, machining will apply a chamfer size between C0.1 and C0.5. However, for chamfers larger than C0.5, modeling is required to ensure accurate pricing.
Hanging Holes for Surface Treatment Require Modeling
Surface treatment processes, such as zinc plating (trivalent) or anodizing, often require parts to be suspended and dipped into the treatment solution. To facilitate this, models must include holes suitable for lifting the parts.
If hanging holes are not present, the following types are recommended, with a minimum of two holes:
- Through Holes: Diameter of Φ3.5 or larger (general tolerance).
- Threaded Holes: M5 or larger.
- Slotted Holes: Width of 5 or larger (general tolerance).
- Irregular Holes: Width of 3.5 or larger (general tolerance).
By incorporating these features into your design, you can ensure accurate cost estimation, smoother manufacturing processes, and optimal results.
