[ Problem Point ]

A strong weld was required.

[ ⇒Kaizen Point ]

Heated with a halogen double-sided heater.
Irradiates infrared light to the welded part of two resin parts to heat and melt the resin,
After sufficiently melting, the resin parts were cooled and joined under pressure.
Welding strength can now reach a level close to that of the base metal.
Furthermore, since only the welding surface is heated, the finish is cleaner.
