Auto Battery Hot Plate Welding
Automotive batteries typically employ hot plate welding techniques due to their substantial size, often exceeding dimensions of 200×200mm. Materials such as PP (Polypropylene), PVDF (Polyvinylidene Fluoride), PE (Polyethylene), and TRU (Thermoplastic Rubber) are highly compatible with hot plate welding processes.
Below, we delve into the working principles and key features of automotive battery hot plate welding equipment.
Working Principle of the Automotive Battery Hot Plate Welding Machine
The Automotive Battery Hot Plate Welding Machine utilizes a flat plate structure and operates through the following process:
Heating:
The plastic components to be fused are positioned between two plastic heating elements.
An electric heating element transfers heat from the heating plate to the fusion surfaces of the upper and lower plastic heating components.
This causes the surface of the plastic components to melt as the temperature surpasses the melting point of the plastic material.
Fusion:
Once the plastic surfaces reach the desired molten state, the heating plate is swiftly retracted.
The upper and lower plastic components are then pressed together, allowing the molten plastic to fuse seamlessly.
Cooling and Solidification:
The welded joint solidifies under consistent pressure, forming a strong, unified bond.
The entire welding process is controlled within a robust frame structure comprising three main components: the upper template, lower template, and hot template.
Equipped with heated molds and upper and lower plastic cold molds, the machine operates under pneumatic control for precise and efficient welding actions.
