Manufacturing capability
Equipment Built Around the Product You Need
From wire preparation to forming, welding, and inspection, our equipment supports standard chains, springs, wire forms, and custom metal parts.
Equipment with a clear purpose
A connected process, not a list of machines
Equipment matters when it helps control the variables that affect your order. Tuohai uses wire processing, forming, welding, and inspection equipment to support link dimensions, repeatability, and order-specific checks. Some machines have been improved around actual production needs.
Complete equipment overview
Explore our equipment by production stage
Use the tabs to see all 18 equipment items currently represented on this page. The equipment used for an order depends on the product, material, dimensions, process route, and agreed inspection requirements.
Forming & wire preparation
Equipment in this group prepares wire and forms repeatable chain links, springs, and wire parts. Tooling and settings must be matched to the drawing or sample.
CNC Wire Forming Equipment
Secondary processing & packing
These machines support finishing, spring end preparation, heat-related processing, surface preparation, and packing where the product route requires them.
Polishing Machine
Welding
The welding method must match the part, material, joint design, and acceptance requirement. Availability on this page does not mean every method applies to every product.
Chain Welding Equipment
Testing & inspection
Test method, sample, load, duration, pass criteria, and required documents should be agreed for the exact product. Accelerated salt spray results are not the same as real service life.
Tensile Testing Machine
In-house equipment engineering
We design and build chain production equipment
Our experienced engineering team designs and builds chain production equipment in-house. The drawing shown here is one example of this work.
Our equipment includes chain forming equipment, chain welding equipment, straightening equipment, and wire forming equipment. These machines support the forming, welding, and straightening work required in production.
Supporting processes
Equipment before and after forming
Production starts with suitable wire preparation and ends with defined inspection. Additional equipment supports straightening, drawing, cutting, grinding, polishing, heat treatment, blasting, and packaging where the product requires it.
Wire drawing and straightening equipment prepare material for stable forming.
Cutting, grinding, polishing, blasting, and heat-related processes support different part requirements.
Packaging equipment supports order-specific presentation and handling needs after final inspection.
Core manufacturing
Wire processing, forming, welding, and inspection are completed in the Tuohai factory for applicable products.
Selected surface treatments
Zinc plating, brass plating, antique finishes, and other treatments may be handled with long-term specialist partners. Confirm the route for your order.
