The person in charge of quality management of Chunlei Machinery Quality Management Department organizes an inspection every week, striving to nip various problems at inspection nodes in the bud, and encourage all links to strictly abide by various laws, norms, and standards, and conduct effective self-regulation. The team leaders of each sub-project organize meetings every day to analyze and record the problems that arise during the inspection work, and provide timely feedback to the quality management team for unified resolution, striving to find problems at any time and study and solve them at any time.
1. Purchase and cutting of raw materials
Chunlei Machinery screens all types of purchased raw materials and conducts inspections on flanges, Strict requirements are set for cylinders and other large and small materials, and incoming material (goods) inspection (IQC) is carried out, using full inspection or random inspection, which effectively prevents unqualified materials from entering the production process.
2. Mechanical processing
Mechanical processing is carried out in strict accordance with the drawings and process requirements to ensure that the dimensional tolerances, geometric tolerances and smoothness of the workpiece meet the requirements. Self-inspection and inspection must be carried out before (after) processing to avoid the production of large quantities of waste products. At the same time, production personnel need to communicate with Quality inspectors check the accuracy of their own measuring tools to avoid scrap products due to errors in measuring tools.
3. Assembly
During the equipment manufacturing process, the butt joints of materials must comply with the requirements of the drawings. Arcs must not be struck on the materials or the raw materials may be deformed. The butt welds must not exceed the specified length. At the same time, surface rust, iron slag and other debris must be treated and the surface of the castings must be cleaned. Remove burrs, flash, nozzles, etc., clean key components such as bearings to ensure the beauty of the parts, and perform welding repair and polishing of defective parts.
4. Welding inspection
Welded equipment parts need to be inspected for pores, surface slag inclusions, or large areas of spatter and cracks to ensure that the welding dimensions of the equipment do not exceed the requirements of the drawings, and that there are no under-welds, pits, cracks, or unwelded parts after welding. , problems such as lack of fusion.
5. Paint inspection
When spraying equipment, ensure that the spray gun moves smoothly to ensure that the paint surface is smooth and clean, and to avoid bubbling, cracking, peeling, sagging, wrinkles, etc.
6. Installation and debugging
During the installation and construction process, our company signed a project quality target pre-control letter with the project party, and the project party signed a quality control agreement with each team of the installation team, and adopted an internal reward and penalty system to ensure project quality through economic means. During the installation and debugging period, the installation and debugging personnel will carefully prepare the installation technical standards, installation inspection forms and installation plans for each equipment, and use materials according to the specifications specified in the drawings. After the installation project is completed, the installation and debugging team will conduct a self-inspection, and then review it by the quality inspector, and then The owner shall inspect and ensure that all records and visas are kept complete and complete.
