CODESIGN
Tamau helps the customer in design development. We ensure the feasibility of the project suggesting engeneering amendments suitable for the foundry mass production.
These are few suggestions:
- Eliminate angles < 0.8.
- Deter material thicknesses less than 2 mm (this is in order to make the injection easier and to reduce deflection).
- Avoid sudden section variations
- Harden surfaces as more as possible so to reduce deflection risk.
- Detail/emboss a wide selection of Identification Markings.
Example
Indications for holes and slots:
The table below is an example of few suggestions Tamau recommend when it comes to design holes
| Ø | THROUGH HOLE (mm) | BLIND HOLE (mm) |
|---|---|---|
| 2 ÷ 4 | Ø x 1 | Ø x 0.6 |
| 4 ÷ 6 | Ø x 2 | Ø x 1 |
| 6 ÷ 10 | Ø x 3 | Ø x 1.6 |
| > 10 | Ø x 4 | Ø x 2 |
* parameters valid for the most common metals. Customized analysis on other alloys on request.
In some cases it is necessary to use oversizes, for the more restricted tolerances:
| DIMENSION (mm) | SUGGESTED OVERSIZE (mm) |
|---|---|
| 0 ÷ 18 | 0.50 |
| 18 ÷ 50 | 0.70 |
| 50 ÷ 120 | 1.00 |
| 120 ÷ 250 | 1.5 |
