Lost-Wax Casting Technology｜Precision Casting Process for Heat-Resistant Steel Components 

Introducing lost-wax casting technology for complex and heat-resistant components. Achieve smooth surfaces, high accuracy, and cost savings by eliminating welds.

■ Overview
Lost-wax casting is a precision casting method that creates ceramic molds over wax patterns. This technique enables the production of highly accurate metal parts with smooth surfaces. It is especially effective for heat-resistant steel, with support for large component sizes up to 1,400 × 900 mm.

■ Features
- High-precision casting with smooth surfaces using ceramic molds
- Compatible with various heat-resistant steel grades (JIS/ASTM)
- Baking at 1,050°C and casting up to 1,600°C
- Near Net Shape production reduces post-processing and costs
- Lightweight with easy reinforcement options
- Ideal alternative to welded components

■ Capabilities
- Max casting size: 1,400 × 900 mm
- Supported steel grades: SCH2 (HC), SCH11 (HD), SCH13 (HH), SCS13 (CF-8), etc.
- Production bases: Japan (ITOH-KIKOH, TOBA TECNO METAL), China (IKK Dalian)
- In-house design and engineering support tailored to customer needs

■ Application Examples
- Radiant tubes and hearth rollers in heat treatment furnaces
- Shot blast and shot peening machine parts
- Heat-resistant trays and metal jigs
- Complex-shaped automotive components

■ Applications
- Components for industrial furnaces and heat treatment systems
- High-temperature conveyor equipment parts
- Precision jigs requiring heat resistance and durability
- Automotive and energy components used in high-heat environments

Lost-wax casting offers optimal solutions for producing high-precision, heat-resistant, and cost-effective metal components.
