Explore precision fabricated parts for prototypes, production runs, equipment assemblies, and industry-specific applications.
Tongyong Industries is a global B2B custom manufacturing solutions provider. This site showcases our sheet metal fabrication capabilities — with manufacturing carried out in China since 2003 and an international business entity in Singapore.
We help customers solve sheet metal challenges — from tight tolerances and material selection to fast prototyping and stable production — through laser cutting, metal stamping, bending & forming, welding & assembly, and surface treatment, all under one roof.
Whether you're vetting a second supplier for peace of mind, bringing a first prototype to life as a startup, or don't have an in-house engineering team to lean on — send us your drawings and we'll walk you through material, tolerance, and process options before you commit.
Manufacturing is carried out through Shantou Tongyong Hardware Industrial Co., Ltd., which holds ISO 9001 certification within the scope stated on its certificate.
From concept to completion, we deliver high-quality sheet metal enclosures and components tailored to your exact needs. Explore how our expertise, advanced equipment, and strict quality control help our customers succeed.
