How to Automate Pallet Welding? Using a Hot Plate Welding Machine.

Equipemt Application Case —— Huazhuo Automation Group Equipment Application Case (China)

Case Background

Hot plate welding is a well-established plastic welding technology widely used in automotive interior and exterior parts manufacturing, such as storage boxes, water tanks, oil reservoirs, glove boxes and flow channel plates. In recent years, this technology has also been increasingly applied to plastic pallet welding, especially for heavy-duty and reinforced pallet structures.

The pallet hot plate welding machine is an automated welding system designed for thermoplastic pallets and large flat plastic components, achieving high-strength and well-sealed joints through hot plate heating, pressing, and controlled cooling.

Equipment Overview

The system is customized according to pallet size and material characteristics. By adjusting the positioning and limit plates, the same machine can accommodate pallets of different dimensions.

Key Features

Large welding area, suitable for oversized flat components

High welding strength, with joint strength close to or equal to base material

Excellent sealing performance, suitable for load-bearing, waterproof and dustproof pallet structures

Stable process for thick-wall and reinforced plastic designs

Applicable Materials

PP/PE/HDPE/ABS,etc

The system is particularly suitable for thick-walled and structurally reinforced pallets.
