  • Hot Plate Welding

High-strength welding, and highly reliable airtight welding

A technique in which plastic is melted by bringing it into contact with a high-temperature plate, and then pressed into contact to join before the molten part cools.

This ensures high-strength welding, and highly reliable airtight welding.

We handle many parts produced from plastic molds, and we can achieve quicker development times and higher quality with the use of this hot-plate welding in-house.

Leak testing with helium gas

We check airtightness of welded products using helium gas leak testing equipment.

The welding and leak test conditions are recorded for each product and are traceable.
