Quality

• Quality control and inspection system

In order to meet the needs of market requirements of users, we must strengthen quality management and formulate necessary rules and regulations to ensure the improvement of product quality. The quality management system includes the formulation of raw material quality standards, quality control, analysis, tracking and assessment management.

Formulation and management of quality standards

• Based on industry standards, combined with enterprise objectives and customer quality requirements, the production department is responsible for determining the quality standards of finished and semi-finished products, and revising the enterprise quality indicators according to the development and changes of production.
• Quality indicators are managed at three levels: enterprise, workshop and team.
• Establish a quality management system and distinguish the quality responsibility. The key is to implement the quality responsibility to the person.

Quality control and tracking 、Workshop staff shall:

• Carefully implement the work standards and do not operate in violation of regulations.
• Strictly check the identification of raw materials according to the shift to eliminate the misuse of raw materials. Check and be responsible at all levels.
• During the tour, strictly control the process standards and do a good job in cleaning. If continuous nonconforming products are found, stop the machine immediately for treatment. If they are not handled properly, do not start the machine.
• In case of shutdown due to mechanical reasons, the equipment must be comprehensively inspected to eliminate quality accidents caused by mechanical reasons.

Quality analysis

• The quality personnel in charge must go to the production workshop every day to analyze the nonconforming products and make records.
• In case of sudden nonconforming products or other quality fluctuations, quality analysis shall be carried out at any time, timely report to the leaders of relevant departments, and effective measures shall be taken to stop the continuation or expansion of the accident.
• Hold quality analysis meetings regularly and carry out quality analysis activities in combination with production conditions.

Management and assessment of quality accidents

• When a quality accident occurs in this process, it shall be reported to the workshop and relevant departments in time, effective measures shall be taken to stop the expansion of the accident, and the quality accident must be traced and analyzed to find out the causes and completely solve the problems.
• Unqualified products caused by quality accidents shall be stacked separately from qualified products and handled properly.
• According to the size of the accident, the person in charge of the accident can be educated, fined or even given administrative sanctions.
• The accident analysis meeting shall be held for the process where the quality accident occurs, and the form of pre shift and post shift meetings and blackboard newspaper can also be used to publicize the quality of employees, so as to attract great attention the occurrence of similar quality accidents.

(2)Incoming inspection control of raw materials

Standard :

ASTM D1000 with test report

G / t12834-2002, with test report

GB8624-1997, with test report

Q/SH002. 07.z.234-1998, with test report

EN12068

Inspection items:

Packaging: moisture-proof and complete marks (manufacturer, trademark, certificate of conformity, name, model, batch number, net weight, moisture-proof, moisture-proof, etc.)

Sampling method: each batch shall be sampled according to 5% of the packaging units, but in small batch, the sampling quantity shall not be less than 3 packaging units.

The raw materials shall be inspected by the quality inspection department of the manufacturer. The manufacturer shall ensure that the products meet the standard requirements and provide relevant inspection certificates.

The company conducts acceptance according to the order standards and relevant national / industrial standards. If one of the inspection results does not meet the technical requirements of this standard, it shall take samples from twice the quantity of packaging units to recheck the item. If the recheck results still do not meet this standard, the batch shall be treated as unqualified.

The product quality certificate is required, otherwise it will not be accepted.

Other items shall be determined or entrusted according to the supplier's test report

• Quality control production process quality control

The company has established a complete and documented quality inspection system to ensure that all factors affecting the safety, reliability, adaptability of on-site installation and operation and long-term service performance of products have been considered, and all factors of test, identification and inspection have been considered in the implementation of the system.

• Carefully implement the relevant quality management terms, manufacturing specifications and standards in the contract and agreement, implement the plan in combination with the company's quality manual and quality control procedure document, and supervise and inspect the implementation.
• Specify and implement feasible quality plans according to the project conditions to ensure that all quality indicators of the supplied products meet the requirements of relevant regulations.
• Review of manufacturing organization design and manufacturing technical measures.
• Prepare the appraisal plan of measuring instruments, organize the implementation, supervise and inspect the implementation of production specifications.
• In addition to normal sampling and inspection, regularly check the sampling and inspection of all materials, production processes, equipment and measuring machines and tools.
• Be responsible for the synthesis, analysis, feedback, processing and storage of the quality information provided.
• Report to the owner on the completion of basic product quality management and quality indicators, and establish quality data files at the same time.
• Combined with the product characteristics, organize education and QC group activities, and do a good job in serving users in the whole production process, so as to make the product quality meet the satisfaction of the owner.
• To ensure the effective operation of the responsibilities of the quality management organization, the branch shall assign full-time quality management personnel to organize the implementation.
• Strictly control the quality, supervise and inspect the product quality, and take full responsibility.
• Close the material inspection and process
• In case of any violation of operating procedures, technical measures and other requirements in production, adhere to the principle and put forward rectification immediately.
• Collect and sort out the inspection records in the production process, and participate in the dynamic analysis of product quality and accident investigation and analysis.
• Coordinate technical personnel to conduct quality assessment of divisional, sub divisional and unit.
• Finished product delivery inspection system

Maintain the traceability of inspection records. Each production post has established a set of conventional production records and documented quality inspection system to ensure that all factors affecting product safety, reliability, on-site installation and operation adaptability and long-term service performance are considered in the production records. After the products are delivered and shipped, the records shall be kept for 3 years for use by the owner during acceptance and various inspections.
