Hot plate welding machine Refrigerator Door Gasket Welding Machine

resistancefor gaskets220V single phase

The Refrigerator Door Gasket Welding Machine is designed for welding refrigerator door gaskets and rubber gaskets. It offers a compact structure, convenient operation and accurate temperature control. Available in double-corner and single-corner configurations (automatic, semi-automatic and manual) to suit factory production lines and mobile/field repair needs.

Key features

• PLC industrial automation control with OMRON pneumatic components to ensure program stability and consistent process control.
• Double-hole fully automatic design with automatic removal of remaining material for smooth, strong and aesthetic welding angles and improved production efficiency.
• Mold and tooling divided into upper and lower layers; driven by precision linear guide rails to ensure positioning accuracy. Typical welding sequence: automatic heating (baking) → vacuum adsorption → welding edge cleaning → internal cooling → external cooling → automatic ejection.
• Comprehensive safety protection including photoelectric protector at the mold front, two-hand start button and cut-off switch (electrical box opens only when power is off) to reduce crushing and electrical risks.
• Available for industrial production (double-corner and automatic single-corner) and for portable/out-of-town maintenance (manual single-corner) with simple operation steps.

Variants / Usage

• Double Corner: for high-volume production lines requiring two-corner welding per cycle; emphasizes automation, stability and consistent weld quality.
• Automatic Single Corner: high-power automated option for single-corner welding in production environments.
• Semi-automatic Single Corner: combines automated and operator tasks for routine 90° sealing strip welding in daily production.
• Manual Single Corner: portable, lightweight unit for field repair and mobile operations; simple four-step operation for maintenance teams.
