automaticfor plastic pipefor the plastics industry

Product overview
MM-Tech supplies a high-pressure butt fusion welding machine designed for field and workshop joining of HDPE, PP and PVDF piping. The SWT-V250/90SHP is engineered to meet ISO 21307 and ASTM F2620 requirements for high-force fusion procedures, making it suitable for water, gas and industrial pipeline projects.

Key features

• Hydraulic valves with cartridge design for simplified maintenance and fast part replacement
• Trimmer driven by a Makita electric drill and worm-driven powertrain for precise facing
• Outer and inner clamps machined from engraved aluminum for consistent pipe alignment
• Hydraulic hoses mounted on the frame in stainless steel to reduce corrosion and cracking
• Heating plate with Dupont Teflon coating and stainless steel junction box for durable temperature control
