Production flow

Heading:a coil of wire is cut to the required length and each piece compressed and shaped into balls using a pressing machine.

Flashing:the surface of the balls is ground to remove the bands generated in the heading process.

Heat treatment:after the bands have been removed, the balls are quenched and tempered to give them sufficient strength and durability.

Grinding:in addition to removing parts decarburized in the heat treatment, this process adjusts dimensional precision and finishes the balls to the stipulated dimensional difference.

First lapping:the dimensional precision of the balls is further improved and they are finished to the specified dimensional difference.

Second lapping:in addition to increasing the balls' dimensional precision to grade level, this process gives the surface of the balls a smooth, glass like finish.

Visual inspection:all of the finished steel balls and their entire surface visually inspected automatically. These visual inspections ensure that the balls supplied to customers have no flaws.

Packaging:balls that pass visual inspection are treated with anti-corrosive oil and then packed in paperboard boxes.

Quality assurance

After precision washing, oiling & before packing sample balls from the batch are sent for final audit to check for surface roughness, roundness, waviness, lot size variation and hardness in a sophisticated laboratory, according to specified control plans and dock audit procedures. Once all requirements are met, a test certificate is then prepared for the customer. Our sophisticated laboratory is equipped with high precision, worldwide respected machines and equipment and is managed by properly trained and qualified personnel.
