Sizing & Coining
Sizing and coining re-press sintered parts to tighten dimensions and improve surface density and appearance. Huaxiao delivers sizing & coining as part of our ISO 9001:2015 certified Powder Metallurgy capabilities — from rapid prototyping to high-volume production, with full dimensional inspection and material certification on every order.
What Is Sizing & Coining?
Sizing & Coining is a specialized capability within our Powder Metallurgy service. Sizing and coining re-press sintered parts to tighten dimensions and improve surface density and appearance. It is chosen when parts demand the specific combination of geometry, tolerance, material and volume that this process delivers best. Our engineers select and fine-tune the exact parameters for your application to balance performance, lead time and cost.
