CASE HARDENING

Several types of furnaces are used for this treatment and this combination of equipment provides the facility to process a wide range of parts ranging from a few grams to many hundreds of kilograms each.

8

BATCH SEALED QUENCH FURNACES

Furnace chamber sizes are 1220mm x 915mm x 610mm with a maximum gross loading of 1000 kilograms.

Products can individually jigged to reduce distortion

8

CONTINUOUS MESH BELT FURNACES

The two units are semi automatically controlled using computers to manage and record the process from pre-set conditions providing complete traceability.

This type of furnace is used for volume heat treatment of fasteners, washers and pressings using an oil hardening quench system and on-line tempering.

8

ROTARY RETORT FURNACES

Suitable for small fasteners and machined components. Parts rotate slowly in a heated metal retort and are then water quenched followed by batch tempering.
