At Birikim Cıvata&Talaşlı İmalat quality control procedures begin with creating the quality control plan for specific product. This plan includes all quality controls from the first raw material input to the final product output. As standart these controls are applied on every product:
- Control of raw material input: includes correction of raw material with necessary chemical analyses and mechanical tests, quantity, doing control of measure suitability.
- Interlude Control: includes controlling the products that are produced from every machine during production by periods according to measure precision. Period of control is maximum 30 minutes. This duration may be shortened according to measure precision.
- Process Control: When a product passes from one process to the one other, ISO 2859-1 standart is applied unless otherwise specified, and sample is analyized. Unsuitable product is prevented to pass to next processes.
- Final Control: After product is done, sample is analyized according to ISO 2859-1 standarts, products are allowed to delivery if result is positive.
