Manufacturing

From Powder to Finished Part Under One Roof

Eight stages, all in house, which is why grade advice comes from the people who press and sinter the part.

Weighing In of Ingredients

Tungsten carbide powder and cobalt binder weighed to the grade formula.

Milling

Powders wet milled so the binder is evenly distributed through the mix.

Spray Drying

The slurry is spray dried into free-flowing granules that press consistently.

Testing

Granulate checked before it is committed to a press run.

Forming

Blanks pressed on imported presses from the mould for that part.

Sintering

Sintered at around 1450 degrees C in an over-pressure furnace to close porosity.

Machining

Ground and finished to the dimensions on the drawing.

Quality Control

Physical properties, shape and tolerance checked, then inspection photographs sent before delivery.
