Mold Polishing Stones
Fine-grit stones in every working section — for dressing mold cavities and taking steel to a polish.
WHAT THEY ARE
Where molds meet their finish
Mold polishing stones are the hand tools of the mold shop: fine-grit stones rubbed by hand along cavities, ribs and parting lines to remove tool marks, erase machining steps and bring the steel surface up to a polish before final buffing.
The work is done section by section — a flat stone for open faces, a round or half-round one for grooves, a triangular one for corners. That is why we produce this series in so many cross-sections, all in fine grits and all made to order.

SECTIONS & GRITS
What we produce
Flat bars — the general-purpose section for open faces and flat surfaces.
Round, half-round and square bars — for grooves, slots and inside radii.
Triangular sections — for corners, ribs and hard-to-reach detail work.
Fine-grit bodies in silicon carbide, white alumina and chromium corundum — body and grit set per your finishing step.

Common questions from buyers
Can you produce non-standard shapes and sizes?
Yes. Non-standard shapes and sizes are welcome — we work from your drawing or a physical sample.
What grit range do you cover?
Typical ranges run from 120# for coarse work through 8000# for fine finishing; other grits can be produced to order.
What dimensional tolerance can you hold?
We normally hold around ±0.5 mm on dimensions; tighter targets can be discussed against your drawing.
Do you support OEM and private label?
Yes. Handle fitting, embossed marking and retail packaging can be produced to your own requirement.
What about MOQ and lead time?
MOQ and lead time follow the item you need; we set them per product and confirm them with the quotation.
