SMC Mould

Moulds are produced from High grade steel and with hardening HRC 48-52.

Beryllium bronsze applied in the punch & Cavity to make the cooling more efficiently.

Moulds were designed for fully automatic production, off-tool parts.

1. Mouldbase

Standardization Use, whenever possible metric standards like LKM for all the mould components. (including guidebushing, guide pin, ejector pin and so on.)
2. Moudbase surface finishing
All plates should be painted with automotive paint blue or green to protect against the corrosion.
3. Cores & cavities
The cores, cavities and inserts made of stainless steel, hardened and tempered up to 45-48 HRC.
Surface finish: Mirror Finish-Diamond Polished.

4. Core wedge blocks

To be manufactured from P20 local steel and heat treatment by gas nitriding.
Wedge blocks need to be located in deep pockets to prevent movement.
5. Steel hardness in general
It is good practice and necessary to have a difference of several points HRC hardness between
sliding steel mould parts to prevent pick up between the steel parts. For example any P20 core slides
or wear plates should be gas nitride.
