Custom Carbide Parts to Drawing
Most enquiries here start with a drawing and a part that is wearing out too fast. This route covers what happens between that drawing and a repeatable bulk delivery, and what has to be decided at each step.
What Happens At Each Stage
Each stage lists the thing that usually goes wrong and what we do about it.
Drawing Review
Problem. A drawing alone does not say whether the failure mode is abrasion, impact or chemical attack, and the wrong grade fails the same way the old part did.
The drawing is reviewed together with the fluid or workpiece, solids content, temperature and pressure cycle before any grade is fixed.
Grade Selection
Problem. Buying one universal grade means over-paying on some parts and under-performing on others.
Cobalt content is matched to the duty: lower cobalt such as YG6 for clean abrasive wear, higher cobalt such as YG15 where impact and pressure shock dominate.
Tooling
Problem. A new mould on every enquiry stretches lead time and raises unit cost on small batches.
A large set of existing moulds covers standard and near-standard shapes; a new mould is only cut when the geometry genuinely needs one.
Pressing and Sintering
Problem. Uneven green density leaves porosity that shows up as early cracking in service.
Blanks are pressed on an imported press and sintered in an over-pressure sintering furnace, which closes residual porosity and stabilises density.
Grinding
Problem. A large grinding allowance pushes the finished cost onto the buyer.
Pressed geometry is regular with a small margin on boundary dimensions, so less stock has to be ground away.
Sampling
Problem. Committing a bulk order to an untested part is how a wear-part change goes wrong.
Samples are sold for pre-testing so the part can be run in service before bulk production is released.
Inspection
Problem. Parts that measure differently between reorders break interchangeability in rebuild kits.
Physical properties, shape and tolerance are checked before shipping, and inspection photographs of the order are sent for confirmation before delivery.
Repeat Supply
Problem. A second supplier means a second set of dimensions and a second qualification cycle.
Repeat parts run from the same mould and grade, so the qualified part stays the qualified part.
The Production Route Behind It
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.

Custom Carbide Parts to Drawing FAQ
What do you need from me to quote a custom part?
A drawing or a sample, the quantity, and the service conditions: what the part runs against, temperature, and whether the load is steady or cycling.
Can you work from a physical sample instead of a drawing?
Yes. A sample can be measured and reproduced, and the grade chosen from the service conditions you describe.
How long does a custom part take?
Customised items carry a delivery time stated in the quotation. Stock items ship 3-5 days after payment is received.
Do you charge for samples?
Samples are sold rather than given away. Send the drawing and service conditions and a sample can be quoted.
Is there a minimum order quantity?
Not published on the source material. confirm with the sales team along with your drawing and quantity.
