Round ones, thin ones, and the ones that the cooling body was put in the cavity are technologies of the friction welding joint of Seimitsu Industrial Co., Ltd

Please see the finish. We would like to introduce the excellent friction welding technology of Seimitsu Industrial Co., Ltd.

Friction welding to the ball, Ball joint

We can friction weld a commercial bearing steel ball to an arbitrary shaft without the marring.

Ball joint before joining

Ball joint before joining

Ball joint after friction welding

Ball joint after friction welding

We can friction weld if the joint diameter is φ5-110, but there is a possibility of the wound depending on the size. We will correspond promptly if you ask the material and shape.

Hollow cylinder and sphere

We can join thin parts.

This is a hollow sylinder after friction. Cooling liquid was put in the U-shape container and sealed by friction welding. The cylinder can float in water.

中空の円筒摩擦接合前

Friction welding of hollow sphere

We can friction weld hemisphere parts both.

Before joining. The cooling body was put in the U-shape container and sealed by friction welding.

摩擦接合前の中空球体

Hollow sphere after friction welding. The sphere can float in water.

摩擦接合後の中空球体

Friction welding of sphere parts that gel entered. #Patent pending

Our friction welding of sphere parts that gel entered has the effect of cold insulation of minus 15 °C. Leakage never accurs with this product unless the material is destroyed.
