Often the pieces and the positive and negative plates have mold
hardness, high gloss, high heat distortion when small. The part
is in direct contact with a large manufacturing plastic and pressure; therefore, that the pieces of
puzzle to have high rigidity.
At the request of the customer to the product diversity can be both pressed
black perforated products, both white laminated products, so pay attention to
the ability to achieve mirror surface gloss of the negative part of the mold (surface roughness
after polishing the lower 0,05Ra). Want to achieve gloss mirror
and stainless, choice of materials normally pay much attention to the function
of chromium.
The material most commonly used for this section is:
- 35CrMo2: good for outsourcing, but not good for polishing and
Engraving.
- 40CrMnMo7: this material somewhat difficult but easy to beat outsourcing
ball as well as carvings.
- 40NiCrMoV4: this is the type commonly used to make pieces or
completely hardened sheets.
- 40Cr13: this type of bear polishing and corrosion, heat reaches a
high rigidity.
