PVC pipe fitting mould/ drainage fitting mould /soundproof system

Specifications

PVC molds are manufactured from DIN 1.2316 and hardening of cores and moving parts guarantee the long life time of the moulds.

 

Materials:

 Mouldbase: Standardization

Use, whenever possible metric standards like LKM for all the mould components. (including guide bushing, guide pin, ejector pin and so on)

 Moudbase surface finishing

  All plates should be painted with automotive paint blue or green to protect against the corrosion.

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

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.

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)
