Engineered Plastic Balls

Exploring the Unlimited Possibilities with Ball Products

Compared to regular and stainless steel, plastic is lighter and has such properties as acid and base resistance, electrical and thermal insulation and magnetic resistance.

They can add color and additional materials in their production process so that their balls meet particular specifications such as a certain relative density and resistance to heat, wear or chemicals.

Sato Tekkou’s products are used in a wide range of fields including advanced functional valves, medical parts, cosmetics products, computer components and low-weight bearings.
