Quality control

We have adopted a comprehensive quality control system. We administer measures that ensure final product quality, by conducting a wide range of quality control tests at different stages of our production process.

Raw materials quality control

All incoming raw materials used in our production processes are subject to inspection upon receipt at our factory, before being warehoused. We conduct sample inspections and tests on our raw materials when they are delivered to our manufacturing facilities, to ensure that they are in accordance with our standards. We document all quality control checks on all raw materials and conduct regular reviews on our suppliers. Raw materials that fail to meet our standards are returned to our suppliers for corrective measures or for replacement at the supplier’s own cost.

Production quality control

Our quality control personnel monitor our production processes to ensure consistency in the quality of our products. Work-in-progress products are checked by the designated quality control personnel before being passed on to the next stages of production. The quality control personnel at the next stage of production re-examines the work-in-progress products received, to ensure there are no defects before the products are further processed. For example, the diameters of the tungsten carbide buttons which form part of our casing systems, button bits and bit openers are measured to differences of 0.0001 mm, and then sorted into various groups for insertion to ensure maximum fitting.

Product quality assurance

At the end of the production process, we physically inspect our products on a sampling basis to verify that their mechanical and dimensional properties and strength meet quality standards and specifications before delivery to our customers. In addition, we conduct a full test run of all of our down-the-hole hammers before delivery to our customers.

Distributor and customer feedback

We relay feedback from distributors and customers on product quality issues to our quality control staff, who implement corrective measures in our quality control procedures when necessary.
