How We Make It

MANUFACTURING PROCESS

Every carbide rod is produced through a precisely controlled 6-step process, ensuring consistent hardness, dimensional accuracy and surface quality.

01

Raw Material Preparation

Premium WC powder and cobalt binder are precisely weighed and batched to specification.

02

Load the Vessel

Mixed materials are loaded into the sintering vessel under controlled conditions.

03

Vacuum Condensation

High-temperature vacuum sintering bonds WC particles into a dense, uniform structure.

04

Clean, Polish & Dry

Rods are surface-cleaned, precision-ground and dried to meet dimensional tolerances.

05

Quality Inspection

Hardness, TRS, density and dimensional checks performed on every batch.

06

Packaging & Shipping

Individual protective packaging ensures rods arrive damage-free worldwide.
