Quality Control Technicians

The Job

Quality control technicians work with quality control engineers in designing, implementing, and maintaining quality systems. They test and inspect materials and products during all phases of production in order to ensure that they meet specified levels of quality. They may test random samples of products or monitor production workers and automated equipment that inspect products during manufacturing. Using engineering blueprints, drawings, and specifications, they measure and inspect parts for dimensions, performance, and mechanical, electrical, and chemical properties. They establish tolerances, or acceptable deviations from engineering specifications, and they direct manufacturing personnel in identifying rejects and items that need to be reworked. They monitor production processes to ensure that machinery and equipment are working properly and are set to established specifications.

Quality control technicians also record and evaluate test data. Using statistical quality control procedures, technicians prepare charts and write summaries about how well a product conforms to existing standards. Most importantly, they offer suggestions to quality control engineers on how to modify existing quality standards and manufacturing procedures. This helps to achieve the optimum product quality from existing or proposed new equipment.

Quality control technicians may specialize in any of the following areas: product design, incoming materials, process control, product evaluation, inventory control, product reliability, and research and development. Nearly all industries employ quality control technicians.
