25KW HF slide welding machine

Product Introduction

This is a 25KW HF slide welding machine designed for batch welding of large workpieces, featuring a "push-pull slide + vertical pressing" structure. It is suitable for welding PVC, PU, TPU and other thermoplastic materials:

The slide can be pushed and pulled back and forth, allowing workers to load/unload materials outside the machine (avoiding contact with the welding area). With 25KW high-frequency power and 2500KG pneumatic pressing force, it achieves high-strength sealed welding for 1200*1400MM large workpieces (e.g., large plastic water tanks, industrial soft bags), with weld strength ≥25KG pull force.

It has a built-in spark suppression system to intercept abnormal discharge in real time (reducing material burn during welding). The semi-enclosed shielding cover ensures the operation area radiation meets industrial safety standards; additionally, emergency stop and overload protection devices make operation more reliable.

Product Features

Safe Slide Operation: Push-pull slide design enables loading/unloading outside the machine, preventing workers from touching the high-temperature welding area.

Multi-Material Compatibility: Works with PVC, PU, TPU and other thermoplastic materials, meeting welding needs of large workpieces.

High-Pressure Sealed Welding: 25KW high-frequency power output + 2500KG pneumatic pressing, ensuring 100% sealed welds and ≥25KG pull force for large workpieces.

Low-Waste Protection: 0.1s-response spark suppression system keeps welding burn rate <0.5%, reducing material waste.

Safety Compliance: Semi-enclosed shielding cover + multiple safety protections, operation area radiation meets GB/T 18268 standards.

Large Workpiece Adaptation: 12001400MM slide worktable fits large plastic/soft material workpieces ≤12001400MM.

FAQ

1.Q: Is the slide push-pull manual or automatic?

A: It supports pneumatic automatic push-pull mode, enabling semi-automatic loading/unloading to greatly reduce labor intensity.

2.Q: What thickness of TPU material can the machine weld?

A: It adapts to 5-15MM thick TPU material, meeting the welding strength requirements of large workpieces.

3.Q: How long is the welding time per workpiece?

A: Depending on the workpiece specification, welding time is about 20-30 seconds; the slide design allows "loading/unloading and welding to proceed simultaneously".

4.Q: How many workers are needed to operate the machine?

A: Only 1 worker is required to replenish materials and collect finished products; the core welding process is completed automatically by the machine.

5.Q: Will the welded workpiece deform?

A: No, the machine is equipped with a constant temperature cooling system to cool and shape the workpiece quickly after welding, with a deformation rate <0.3%.

6.Q: What should be noted for daily maintenance of the machine?

A: Daily maintenance involves cleaning the slide rail and welding mold; core components (electron tube, cylinder) should be inspected every 6 months.

7.Q: Can the mold be replaced to adapt to different workpiece specifications?

A: Yes, it is equipped with a quick mold change structure, and the time to replace a large mold is about 30 minutes.

8.Q: What is the power supply requirement for the machine?

A: It needs to be connected to a 380V three-phase industrial power supply, with a voltage stabilizer of 35KVA or above to ensure stable operation.
