1. Application details:

Can weld/repair all kinds of dies, injection dies, die-casting, pressure casting dies, metal products, machine spare parts, etc

2. Suitable material

Aluminum material, aluminum alloy, copper material, copper alloy, low carbon steel, medium carbon medium, die steel, stainless steel, casting steel, cast iron, cast aluminum, tungsten carbide alloy, and all electrical conductor.  

3. Suitable defect can be repaired /welded

Repair/welding pin holes, gas hole, burring, flash, bump, scuffing, edge chipping, pinhole porosity, crackle, abrasion, wear and tear, miscalculation in manufacture, defect in manufacture, welding defect. 

4.  The position of the machine can welding

 Repair/welding sharp corner, sharp-edged orifice plate, groove or furrow,

side wall or jamb, bottom, deep cavitiy, flat surface, and etc.

 2.SZ-08 welding/ repairing function:
Injection mould: Defects like wear out, bruising, scratches, hole, etc, eliminate products' flash, burr, etc.

Die casting mould: Defects like etch, loss, damage, wear out, chap, fracturing, etc

Auto parts casting: automotive crankshaft, piston, cylinder, wheel hub, brake disc, clutch, exhaust pipe casting defects (such as sand hole, porosity, cracks).

Industrial machinery and machine tools: repair size tolerance or wear work pieces, such as repair machine     guideway, large mechanical shaft, gear parts; hot roller, cold roller, hydraulic rod in engineering machinery, printing cylinder, and all other metal components parts defects.

Aviation and shipping manufacturing: Repair/ weld compressor shell, stainless steel precision parts, precision shaft and valve, etc

And other many industry and metal products welding/ repairing.

Model SZ-08 also can weld/ repair brass, copper parts.

2.Can do surfacing rebuilding coating after welding, use tungsten bar to do coating, hardening, intensify metal surface.

3.With more fast speed and good repair result.

HS code: 851590900

Remarks: this type is the fast welding speed, best welding effect, and wide welding range.  

Machine & accessories of SZ-08: ( include electrode/ welding wires) PRICE

Cold welding machine principle:

Cold welding machine is using arc spark effect in the air. Electrode material made of alloys is sparking dissolved and deposited on the metal work piece.

1: Charge: The condenser is charged when electrode and work piece is separated.

The temperature of the spark point is approximately 25,0000°C, however, no heat accumulation occurs during diffusion and deposition periods since the pulse period is extremely short compared to the interval period. 

2: Electro Spark: Electro spark between electrode and base material, only contact area temperature will be approximately 25,0000°C. 

3. Transfer: transfers a small quantity of the electrode to the work piece under an ionized state.

4. Hardening (coating): produces a strong metallurgical bonding.

Mainly Applications
1.Multiple usage: Have the function of welding, surface hardening etc 
2.1Reparing range: Casting products, such as sand hole. Rebuild/restore worn parts.etc

2.2Non-ferrous metal workpeices

2.3Injection mold/die casting: welding & repairing of worn mold, scratches, etc. The zinc & aluminum die casting and also surface strengthening of cavity to prolong their using-life
3.Easy to operate, can do surfacing rebuilding after welding.

4. Fast speed, high efficiency than common welding.

5. The repair effect is better than traditional Arc welding, TIG welding, laser welding, etc. It is very suitable for small defect parts. Very large defect is not available.
