Precision Induction Machines
Reliable Induction Hardening for Components
Isothermal specialises in induction hardening across all types of components, offering low-, medium- and high-frequency induction machines to meet varied job specifications. This focus on induction hardening ensures consistent, controlled surface treatment and repeatable results for parts that require improved wear resistance and fatigue life.
Why choose our induction machines
We began supplying heat treatment services in 1979 and transitioned from flame hardening to induction processing, installing our first induction machine in 1988. Over the years we’ve grown our capacity to six induction machines, allowing us to handle a wide range of component sizes and specifications. These decades of continuity mean established processes, experienced staff and long-term customer relationships.
Capabilities that matter to your project
• Low, Medium and High Frequency induction machines — suitable for surface hardening thin sections through to deeper case depths.
• Flexible production — multiple machines let us schedule jobs to meet lead times and varied production runs.
• Skilled team — a loyal workforce of 14 employees with many staff serving 20 to 30 years delivers reliability and process knowledge.
What we deliver
We provide induction hardening services tailored to component needs: controlled heating, immediate quenching and repeatable hardness profiles. Because our equipment spans low to high frequencies, we can match the machine and process to the part geometry and required case depth, producing cost-effective, durable results for repeat orders.
Quality, experience and customer focus
Isothermal has built long-standing relationships with clients by focusing on service quality and predictable outcomes. Our history in heat treatment and focused investment in induction machines means you get both technical know-how and the practical capacity to deliver on time.
