CHY Welding Dies for Hydraulic Pressure Welding Machines
Matched die sets for CHY100 CHY200 CHY400 and CHY700, covering copper 1.00-13.00 mm and aluminium 1.00-25.00 mm.
Product Overview
CHY Welding Dies for Hydraulic Pressure Welding Machines
CHY dies are cut for a specific machine frame and a specific wire size. The four standard sets cover the whole hydraulic range: CHY100 dies for copper 1.00-4.00 mm, CHY200 dies for 2.00-5.00 mm, CHY400 dies for 4.00-8.00 mm and CHY700 dies for 7.00-13.00 mm, with the aluminium range running wider in each case.

Key Benefits
What This Model Gives You
Matched to the Machine
Each set is cut for the frame it goes into, so the cavity is square to the ram and the upset is even.
Aluminium Runs Wider
CHY700 dies take aluminium to 25.00 mm against 13.00 mm copper, which is the difference that decides the machine size on aluminium lines.
Rectangular Sections Quoted
The range for rectangular non-ferrous wire is calculated from the cross-sectional area.
Consumable Not Capital
Dies are the wearing part. Ordering the recurring sizes as stock keeps the press working.
Application Scenarios
Where It Is Used
- Rod breakdown mills
- Continuous casting and rolling lines
- Busbar and strip production
- Large-section conductor plants
Industries
Problems It Solves
Why Buyers Specify It
- A die cut for the wrong diameter never gives a full upset
- A worn cavity produces joints that open in the next pass
- Buying dies from the machine maker alone limits the sizes available
Compared With Other Models
Portable and desk machines use the SD1 and SD2 die families in much smaller sections. CHY dies start where those stop, at 1.00 mm copper, and run to 13.00 mm.
Use Guide
How It Is Set Up and Run
- Identify the machine model first — the die set is named after it.
- Give the exact wire or rod diameter, not the machine's rated range.
- For rectangular sections, send the cross-sectional area and the profile.
- Replace when the flash stops forming evenly around the cavity.
Customisation and Supply
What Is Built to Order
Dies to Your Wire
Dies are manufactured for wire between 0.10 mm and 25.0 mm to suit round or profile wire and rod, to the customer's own specification, at -1% / +2% of the wire diameter.
Your Electrical Supply
On the motorised and hydraulic machines, operating voltage is built to the industrial supply of the destination country. State voltage, phase and frequency with the order.
Export Packing
Machines are packed in a strong wooden or plywood case as stated per model. Carry cases are supplied with the portable welders and the DA10.

CHY Welding Dies for Hydraulic Pressure Welding Machines Questions
Which die set for a CHY400
CHY400 welding dies: copper 4.00-8.00 mm, aluminium 4.00-14.00 mm.
Can dies be cut for rectangular wire
Yes. The range for rectangular non-ferrous wire is calculated according to the cross-sectional area.
Do CHY dies fit other makes of hydraulic welder
SGT dies are the industry standard type and suit comparable cold pressure welders from other manufacturers. Confirm the die seat dimensions with the enquiry.
What tolerance is held to the wire
-1% to +2% of the wire diameter.
Quote the CHY Welding Dies for Hydraulic Pressure Welding Machines
Give the wire material, the diameter and the country the machine will run in, and the quote comes back with the die set and the voltage build already decided.
