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
