Secondary Operations

A wide range of additional operations or treatments can be carried out on the parts after they have been sintered.

Heat Treatment:-
Sintered parts may be heat treated to increase strength and also hardness for improved wear resistance.

Oil Impregnation:-
The controlled porosity of P/M parts permits their impregnation with oil and resin. This operation is used to give the part self lubricating properties.

Resin Impregnation :-
Used to improve machinability, seal parts gas or liquid tight, or prepare the surface for plating.

Machining :-
All normal machining operations can be carried out on sintered components.

Drilling:-
Usually used for holes not in the direction of the pressing.

Burr Removal:-
Barrelling is used to remove burrs and sharp corners.

Corrosion Resistance:-
Various types of surface treatment are available to increase corrosion resistance to withstand the most demanding of environments.

Finishing:-
Includes, deburring, burnishing, coating oil dip, plating, welding, and mechanical surface treatments.

Other finishing operations can be carried out. Gt.B. will be pleased to quote for any other requirements.
