How to strengthen the quality inspection of injection products?
The inspection work is very important and key to ensure the quality of injection products. Therefore, it must be strengthened.
(1) strengthen the basic work of quality inspection
The basic work of strengthening inspection is to do a good job of quality inspection of plastic parts.
1) strengthen the preparation of quality inspection plan, and organize the implementation of quality inspection according to the production process.
2) strengthen physical and chemical metrology.Measuring the physical and chemical work including testing, testing, analysis, etc, all kinds of plastic parts of the test data by measuring the physical and chemical work, therefore, is a suitable measuring physical and chemical projects, 2 it is to measure to guarantee the physical and chemical work of the accuracy of the instruments, tools and equipment.
3) establish and improve the quality inspection systems of plastic parts, clarify the duties, responsibilities, rights and interests of personnel at all levels in quality inspection, strengthen the assessment of quality inspectors, and strictly reward and punish them.
4) strengthen information work, understand the quality dynamics of raw materials, semi-finished products and finished products, and grasp the rules in time.
(2) implementation of the "three inspections system" involving operators
To make plastic parts meet quality requirements, operators are important factors, therefore, operators must also participate in the inspection, this is the combination of operators and inspectors "three inspection system."It is a kind of inspection system combining "special inspection" of full-time inspectors with "self-inspection" and "mutual inspection" of operators.
1) special inspection.In the production enterprise of plastic parts, the quality inspection is carried out by the professional personnel in charge of inspection of the department, mainly including the inspection of raw materials, the inspection of main processes, the inspection of semi-finished products and the inspection of finished products.
2) self-inspection.This is the operator in the plastic parts product manufacturing process, according to the quality inspection requirements of the plastic parts, the completion of their own work or products for self-inspection, mainly applicable to the process inspection.
3) the absolute.Between the operator on the production of plastic products or mutual inspection work, mainly is suitable for the working procedure, process, shift workers, team up and down between the mutual inspection, etc.
The practice of inspection system and is conducive to the production process each link cengcengbaguan, is beneficial to improve the efficiency of the quality inspection work, to make the plastic parts inspection based on reliable mass base.
(3) self-inspection system
Self - inspection system is the quality inspection system of operators.Operator is directly involved in the manufacture of the plastic product, is an important factor to ensure the quality of plastic parts, therefore, the "three self-checking system" is an effective method to ensure the quality of the plastic parts, including the following content.
1) self-inspection.Operators in their own process after the completion of plastic products processing, that is, the production of their own products for self-inspection, judge whether the products qualified or not.
2) you.After the completion of self-inspection, the qualified products and non-conforming products shall be separated by themselves, and the unconfirmed products may be reinspected by inspectors to determine whether they are qualified or not.Prevent non-conforming products from flowing into the next process.
3 > marks itself.Operators to their processing of each product all want to make their mark in the, so, no matter which way to plastic parts to the following process, once found the problem, they can find a responsible, prompting operators strictly carry out operation procedures, strengthen the sense of responsibility, and responsible for the quality of plastic parts to the end.
