Powertrain Parts

Various springs are used for transmissions (a mechanism to shift gears). These parts help use the engine power effectively and improve fuel consumption, and furthermore accelerate/decelerate smoothly in order for passengers not to feel uncomfortable. Snap rings are also used to hold parts.
Of these springs and snap rings, about 50 parts are used for a car (a single transmission). These products are delivered to both domestic and foreign manufacturers.

Hose clamps are used for fixing hose and pipe in a car to prevent water and oil from flowing, or hoses from slipping. Typical products are plate clamps and screw clamps. Plate clams feature the follower force against hose shot by heat using its own reaction force. We also have other products like double clamp (reinforced type) and clamp with holder for improving workability, holder-less clamp, and so on.
Screw clamps are used mainly in areas where the pull-out force is considered, because the clamps are designed to hold firmly using the axial force of screw.
