Technology / product information

Seamless thin-walled cylinders are cylindrical containers that offer high strength and durability despite their extremely thin walls. Capable of high-precision thin-wall processing with a thickness of t0.05–t0.20mm, they are used in a wide range of applications, including battery cases, sensor covers, precision containers, and pressure vessels. With seamless construction for superior internal volume and reliability, along with compatibility with various materials, they provide an ideal solution for products requiring resilience in precision equipment and challenging environments.

■ Features
- High-precision thin-wall processing: Achieves both lightweight properties and high strength with thin-wall processing of t0.05–t0.20mm.
- Seamless construction: Fully seamless design prevents leakage and maximizes container durability.
- Compatibility with various materials: Supports processing in SUS304, SUS316L, iron, copper, aluminum, phosphor bronze, and more.
