CCCBS Production and Quality Control

Our Copper Cored Cathode Bars (CCCBs) are manufactured and undergo strict quality control to meet the high standards required in smelting operations. We ensure precision engineering, optimal fit and superior performance, providing smelters with reliable and durable components that support efficient and long-lasting operations.

Precision Manufacturing

We manufacture CCCBs with a precise clearance fit between copper inserts and steel bars, ensuring accuracy within a 0.10 to 0.20mm tolerance for maximum performance in smelting applications.

Rigorous Quality Control

Each CCCB is thoroughly measured and inspected, guaranteeing that all dimensional, fit and surface finish requirements are met to deliver consistent, high-quality results for our clients.

Our History

Australasian Smelter Services and Supply (ASSS) emerged from Deep Hole Drilling Specialists Pty Ltd, originally focused on deep hole drilling. Through a process of enterprise-driven growth, the company expanded into smelting solutions, producing Copper Cored Cathode Bars (CCCBs) for major smelters. As operations grew, ASSS became the exclusive provider of cast iron rodding for Australian smelters, further enhancing its industry presence. With the introduction of copper recovery and recycling, the company advanced its sustainability efforts, ultimately rebranding to expand its global smelter support operations.
