Quality Control on Raw Material

Sample Test
1. After receiving the test notice, our inspector will carry out sampling procedure on our cemented carbide products and rock drilling tools. Samples will be marked conforming to the related standard of purchased products. Samples will be sent to the physical and chemical room/ factory to have chemical composition test, technological performance test and other related tests. All the tests are in accordance with the related technical standard and specific regulation of purchased products.

2. The test, referring to the raw material that does not have to be tested, the raw material that should have full test and the raw material that should be tested independently by the inspector, will be carried out on the samples and drawings according to the related standard of the purchased products. The necessary information, such as the specific items, data and illustrations, will be filled in the acceptance check report.

3. The raw material sample that failed in the acceptance check will be firstly commented by the material engineer and secondly reviewed by the manager. If necessary, the failed sample of our tungsten carbide products and rock drilling products should be thirdly confirmed by the head of the product department. The quality engineer will do the final decision, and the confirmation of the head of the quality control department is needed on occasion. The seriously failed raw material sample will be reviewed by the department manager and then handed to the general manager to have its concession approved.


Quality Control on Production Procedure

If the first product is disqualified, the supervisor will point out the failed position and ask the operator to correct and improve. The operator can not continue the production until the first product is qualified after reworking.

3. The operator will have self-inspection during the production procedure. If regulated, the result will be filled in the self-inspection log sheet, monitoring log sheet and other related log sheet.
