The company caters to various industries, including automotive, aerospace, electronics, tooling, medical, recycling, and energy sectors such as nuclear, wind, oil, gas, and solar. It also supports the production of steel, titanium, and aluminum.

Vacuum Arc Remelting (VAR) Furnaces
VAR furnaces are crucial for producing high-quality steels, superalloys, titanium, and zirconium alloys, which are essential for applications requiring cleanliness, homogeneity, and enhanced fatigue properties. These materials are vital for aerospace, power generation, and nuclear industries.

Features and Options of VAR Furnaces

Modified designs for customer-specific stubs and crucibles.
High precision shear beam load cell system for melt rate and termination control.
Elimination of hydraulics to reduce contamination risk.
Extended power ram stroke for compacted electrodes.
Deep vacuum levels and reduced pumpdown times.
High-definition cameras for melt zone viewing.
Programmable bi-directional stirring and helium ingot cooling.
Partial pressure operation and control.

Advantages of VAR Systems

Vacuum or inert melting atmosphere.
Melt rate control based on alloy and ingot size.
Reduction of dissolved gases and undesired trace elements.
Processing of segregation-sensitive alloys.
Controlled solidification to avoid macro-segregation.
Low energy input and ceramic-free process.
Wide range of materials can be processed.

VAR System Types
VAR-T: Designed for reactive metals like titanium and zirconium, available in large, medium, and small systems.
VAR-S: Optimized for specialty steel and superalloy processing, featuring a compact electromechanical design.

Advanced VAR System Features

Free-standing design independent of building structure.
Remote operator control console and PLC-based control system.
Ethernet communication and data acquisition capabilities.
Multiple melt recipe storage and intuitive multi-segment recipes.
Accurate ram drive and X-Y electrode positioning.
Stable DC power supply with excellent drip short control.
Comprehensive melt rate and arc gap control.
360-degree view of the melt zone and stainless steel head liner for improved pumpdown times.
High throughput with quick changeover and ease of maintenance.
