Hydraulic Wire Expanding Machine for Small Diameter Cold Shrink Tube and Rubber Seal Products

Product Description:
  This hydraulic-controlled wire expanding machine is specifically designed for expanding small diameter (5–10mm) cold shrink rubber products, such as insulated short tubes and cold shrink sealing tubes. It is not suitable for diameters exceeding 60mm. The machine features a 650mm hydraulic cylinder stroke, an adjustable expansion length of 100–560mm, and three wire pulling cylinders. After expansion, the diameter ranges from min. 25mm to max. 75mm. The machine comes with a lower closed fence, customizable moulds, and supports voltage transformation for different regional standards.

Application Scenarios:

• Expanding small diameter (5–10mm) cold shrink rubber tubes

• Producing insulated short tubes for electrical insulation

• Manufacturing cold shrink sealing tubes for cable and pipe sealing

• Suitable for precision rubber expansion in insulation and sealing applications

Key Features:

1. Hydraulic control system for stable and reliable operation

2. Adjustable expansion length from 100mm to 560mm

3. Three wire pulling cylinders and one center push cylinder

4. Post-expansion diameter range: 25mm – 75mm

5. Lower closed safety fence for operator protection

6. Customizable moulds according to product size and shape
