Business Details

Combines electrical discharge machining (EDM) technology with surface treatment using U.S.-licensed technology, primarily engaged in contract machining of aircraft engine parts, industrial gas turbine parts, and defense equipment. Major customers are the Mitsubishi Heavy Industries group (37.3% of sales) and the Kawasaki Heavy Industries group. Also engaged in the manufacture and sale of heat- and corrosion-resistant coatings (Thermetal Coating, etc.) and the fully chrome-free anti-corrosion surface treatment agent "ZEC Coat." This is the largest segment, accounting for approximately 72% of group sales.

Recent Overview

Q1 sales rose sharply, up 26.9% year-on-year, driven by expanding demand in aerospace and energy

In Q1 of FY2027 (ending February 2027) (March–May 2026), sales reached ¥3,100 million (up 26.9% year on year) and segment operating profit reached ¥706 million (up 22.4% year on year). In addition to increased demand for aircraft engine parts and defense equipment, equipment for gas turbine parts that was capacity-expanded in the prior fiscal year began phased operation. In the aerospace-related business, profitability is improving through economies of scale. Order intake also expanded substantially to ¥3,595 million (up 42.8% year on year), and demand outlook remains solid.

Key Products

service
Aircraft Engine Parts Contract Machining

Contract precision machining of aircraft engine parts utilizing EDM technology. Demand remains at high levels amid increasing passenger and cargo demand, with profitability improving through economies of scale.

service
Gas Turbine Parts Contract Machining

Contract precision machining of industrial gas turbine parts. Demand is expanding against the backdrop of rising global electricity demand driven by AI adoption, and equipment capacity expanded in the prior fiscal year has begun phased production, contributing to sales growth.

service
Defense Equipment Contract Machining

Demand for defense equipment is increasing due to substantial expansion of defense buildup plans amid strengthened national security. This is contributing to improved profitability in the aerospace-related business.

service
Surface Treatment (Thermetal Coating, etc.)

Provision of heat- and corrosion-resistant coatings (Thermetal Coating, etc.) using U.S.-licensed technology. Contributes to extending the service life and enhancing the performance of aircraft engine parts and gas turbine parts.

product
Chrome-Free Anti-Corrosion Surface Treatment Agent "ZEC Coat"

A fully chrome-free anti-corrosion surface treatment agent developed in response to tightening environmental regulations. Manufactured and sold as a product addressing the need to reduce environmental impact.

Growth Drivers

  • Expansion of gas turbine parts orders driven by rising global electricity demand from AI adoption
  • Increased demand for aircraft engine parts amid recovery in passenger and cargo demand
  • Increased demand for defense equipment due to substantial expansion of defense buildup plans
  • Strengthened supply capacity through phased operation of capacity-expansion equipment implemented in the prior fiscal year
  • Improved profitability in the aerospace-related business through economies of scale
  • Expanded order intake for the gas turbine business in Western markets (strengthened overseas expansion)

Risks

  • Sales concentration among the top four customer groups (Mitsubishi Heavy Industries group alone accounts for 37.3% of sales)
  • Risk from policy changes affecting aircraft demand and defense budgets
  • Risk of fluctuation in gas turbine demand due to shifts in energy policy
  • Risk of rising fixed costs and lower utilization rates associated with production capacity expansion
  • Technology continuity risk in the surface treatment business, which depends on U.S.-licensed technology
  • Risk of impairment losses on fixed assets (given the segment's numerous business sites)
