SUN MACHINERY's precision automotive parts, industrial machinery and production processes.
The difference precision makes —
SUN MACHINERY products
From commercial-vehicle drivetrains and chassis to engine brackets and intake-exhaust piping systems, SUN MACHINERY is responsible across the entire process — design, forming, machining and inspection — for the high-reliability precision parts that automakers demand.
High-reliability drivetrain & chassis core parts
Precision drivetrain and chassis parts responsible for power transfer, steering and suspension — delivering stable performance even under high-load, repeated-fatigue conditions.
DIFF CARRIER ASSY
A core differential-gear assembly component that transfers power from the transmission output to the wheels and compensates for the speed difference between left and right wheels, enabling smooth driving through turns and on uneven roads.
AXLE SHAFT
A core shaft component that transfers engine power to the final wheels. It demands anti-torsion strength under high torque and extreme durability with machining precision.
ARM IDLER ASSY
A core steering-support link module that supports the steering linkage and provides optimal angle transition and link support during steering operation.
STABILIZER ASSY CAB MTG
A modular part connecting the cab to the chassis at the cab front.
Acts as the hinge axis during cab tilting.
Absorbs torsion transmitted to the cab during cornering.
Connects with the air shock absorber to absorb external impacts.
High-strength engine/gear brackets & intake-exhaust piping systems
Parts that support and protect the engine and powertrain and manage intake-exhaust flow, engineered with rigidity and heat resistance to withstand high-temperature, high-load conditions.
Engine Mounting Bracket
A high-strength cushioning support bracket that fixes the engine powertrain to the body and precisely dampens transmitted micro-vibration and noise.
Air Spring Support
An impact-distributing support that fastens the air-spring bellows — a key part of heavy commercial-vehicle suspension — to the side frame of the body.
Exhaust Manifold
A special heat-resistant cast piping module that collects the engine's high-temperature exhaust gas and channels it into the catalytic piping.
Time Gear Case (TGC)
A case that protects the internal timing chain and gears and seals the engine oil to prevent leakage.
Quality proven by numbers
By managing the entire process from design to inspection with data, we deliver the highest level of quality automakers require.
