The ITM Series Tilt Induction Furnaces are energy efficient and cost effective solutions for melting and castings both precious and base metals. The systems are available with either a gas assisted manual tilting mechanism, servo motor controlled pouring system, or hydraulic controlled tilting system for safe, easy and controlled pouring of molten metal. HPT's efficient induction generator ensures rapid melting and thorough mixing of the molten metal with melting capacities from 10 kg to 1 ton of metal. The ITM series is also available in a High Temperature (HT) version capable of reaching 2000°C.

Manual Tilting

The ITM series manual tilt pouring systems uses a gas spring assisted tilt mechanism to ensure the safe and easy pouring of molten metal. With capacities up to 2400cc these systems are ideal for melting scrap jewellery, small castings and bar production

Servo Tilting

The TMS series of tilt induction furnaces are fully automated melting and casting systems. The melting and pouring process is accurately controlled to ensure consistent high quality results. The servo controlled pouring system allows the pouring speed and power applied to the melt to be accurately controlled. These systems are ideal for ingot and bar production.

Hydraulic Tilting

The ITM series of tilt induction furnaces are suitable for melting and casting large volumes of metal. These systems are fully automated making the system easy to use and ensuring the safety of the operator.pouring system allows the pouring speed and power applied to the melt to be accurately controlled. These systems are ideal for ingot and bar production.

 

 

The VHT Series incorporates HPT's innovative induction heating technology and cutting edge vacuum and automation systems to provide a complete solution for melting and casting high temperature metals in a digitally controlled vacuum and inert environment. The VHT is capable of melting various metals including palladium, stainless steel, gold, nickel and other specialized high temperature metal alloys. The VHT is ideal for mining, refining, and high volume production environments, and can be customised for the specific applications.

A high level of system automation ensures consistency in the process and allows all critical melting and casting parameters to be controlled and monitored. Automatic casting programs are also provided.

HPT's laboratory systems are ideal for the production of metal samples for emission or X-ray spectrometric analysis, calibration standards and alloy development. HPT's efficient induction generator ensures thorough mixing of the metal to produce samples with a homogenous composition, that are melt and cast in a vacuum inert environment.
