Specifications

We offere a complete range of PE electrofusion piping systems from 16mm to 315mm in diameter.

 

 

 

Mouldbase: Standardization
Use, whenever possible metric standards like LKM for all the mould components. (including guide
bushing, guide pin, ejector pin and so on)
2.2 Moudbase surface finishing
All plates should be painted with automotive paint blue or green to protect against the corrosion.
2.3. 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
2.4 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.
2.5. 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.
(Steel material and final hardness certificate will be supplied with the molds)
