Ultra-precision Machining Technologies
Thin Leaf Springs
We provide comprehensive support to our customers, starting from analysis and design of various spring properties such as behavior analysis and load and stress analysis using FEM analysis, precision machining technologies such as pressing, heat treatment and shot peening to shape the design, and technologies to evaluate and analyze products.
Features
- We can shorten the development period using abundant know-how and experience as a manufacturer specialized in springs, and product design that integrates FEM analysis.
- Using various heat-treat furnaces, we can provide integrated production from pressing, cleaning, to heat treatment. Facilities owned: Quenching and tempering furnace, austempering furnace, vacuum furnace, continuous hydrogen atmosphere furnace, etc.
- We can treat products with strict product cleanliness. Facilities owned: Clean room, hydrocarbon washing machine, pure water washing machine, cleanliness evaluation facility.
- We can handle trial production of several units to mass production of several millions of units per month.
- We acquired ISO 9000 Series and ISO 14001 certifications, and have received high evaluation from many automobile and electronic manufacturers especially on our quality. We can provide comprehensive support from development and design, trial production, to mass production.
- We can provide thin leaf spring assemblies utilizing laser welding, brazing, adhesive, and adhesive technology.
Possible Range of Production
Material:
Spring steel, stainless steel, phosphor bronze, maraging steel, etc.
Plate thickness:
