Piston – Input

·Material selection – high-strength alloy steel suitable for automotive transmissions.

·Blanking to form the initial piston shape.

·Hydraulic stretching to achieve required dimensions and mechanical properties.

·Heat treatment to enhance strength, hardness, and wear resistance.

·Precision turning to achieve final dimensions and smooth surfaces.

·Deburring and cleaning to meet cleanliness standards.

·Final inspection using 3D coordinate measuring machine to ensure dimensional accuracy.

Used in automotive transmissions to support the input shaft, control hydraulic pressure, and ensure smooth gear engagement.

·High-precision blanking and hydraulic stretching ensure dimensional accuracy.

·Heat treatment improves strength, hardness, and wear resistance.

·Precision turning provides smooth surfaces for optimal hydraulic performance.
