Materials-related Business
High-quality products are made from high-precision materials.
High-precision materials are the core of Suncall’s business
The main strength of Suncall’s business is our Materials-related Business. This department handles the material production side of our comprehensive production process, which starts with high-precision materials and ends with completed products. Our core technology, “plastic processing technology” is focused on achieving “Elongation” and “Bending” as a base. This technology is applied with die development in which wiredrawing processing is used, as well as rolling and heat-treatment technologies for the production of wire materials used in the manufacture of high precision springs mainly utilized in automotive parts.
Providing reliable quality using highly precise technology and know-how
In order to realize the high tensile strength and high durability demanded of springs, our company is engaged with steel manufacturers to design steel components with superior fatigue-resistant and settling resistant characteristics. Thanks to that, we are able to procure best materials in which adulterants are limited. The top surfaces of all procured wiring materials are removed entirely in order to eliminate from products any harmful flaws, as well as decarburized layers. Also, in consideration of the environment, our company is leading the industry in the use of patenting processing that employs a fluidized bed type heat treatment line in which no lead is used. In order to clean material surfaces, we are using automatic washing equipment that enable higher levels of performance to be achieved for wires used to make springs.
