80% of the value of wire was supervised by cable companies and they were "planted" on small problems.

Recently, a relatively special report on the supervision of cable manufacturers was discovered and shared with everyone. On December 19th, the Shenyang Municipal Bureau of Quality Supervision announced the results of the special supervision and inspection of the 2017 wire and cable production permit certified companies. Unlike the previously notified product quality failure project, it reported the results of the factory inspection. Of the 19 certified cable companies supervised this time, in addition to one company that has stopped production and two that have refused inspections, the other 16 companies were found to have more than 40 problems, mainly ranging from raw material procurement and purchase inspection to production. Process, product delivery, full management and documentation.

These issues are very representative, not only reflecting the common problems in the production and management of industrial enterprises, but also seeing another important direction of the industry's special inspections. We have collated it into a list, which is roughly divided into 9 types of questions for everyone to refer to in self-inspection in daily production management or to make plans in the coming year.

1, the record is not standardized, incomplete and missing records

1.1 Missing records: No records of disqualified products disposition (no disqualified product handling records and records)

1.2 Records are not standardized: Inspection records are not standardized (including incoming inspections, process inspections, factory inspections); data modification is not standardized (including stock, process, factory inspection records, and monitoring records); ballpoint pen fills in records; time incomplete/record is not clear Year of labeling; no tester’s signature on the factory inspection record.

1.3 The records are incomplete: The records of key processes and quality control points are incomplete; raw material procurement records are incomplete; the inspector's training records are incomplete; and inspection records (including purchase, process, and factory inspection) are incomplete/incomplete. Among them, the common lack of spark test, thermal extension test, voltage test, insulation thickness, insulation resistance test records; Note: strict and meticulous supervision beyond imagination, check the record to: missing the July 19 YJV0.6/ 1 kv 4*150 cable thermal extension inspection record; KVV 450/750 2*1.0 two-core cable insulation thickness and conductor resistance inspection records are incomplete (only one core tested and two cores should be tested).

2, lack of instrument verification certificate: lack of laboratory thermometer verification certificate; lack of 1000mm steel ruler, thermal extension test weight, thickness gauge verification certificate; laboratory micrometer micrometer (division value 0.001mm) and thermal extension test device is missing Certificate of verification; lack of thermostatic water bath calibration certificate.

3. Absence of related production equipment: For example, extrusion-insulated low-voltage power cable units lack three-layer co-extrusion production lines, annealing equipment, and vulcanizing equipment; again, overhead insulated cable units lack annealing equipment, 1+1 or 1+2, or three layers. Coextrusion production line.

4, process flow chart and actual inconsistency: For example, companies only produce single-core 10kv overhead insulated cables, process flow chart contains multi-core products, and actual inconsistencies.

5, key processes, quality control points, special processes without logo

6, the product packaging logo over the use of

7, the purchase of raw material certificate content without the factory date

8. The placing and marking of articles are not standardized: The raw materials storehouse is not standardized, the mark is not obvious; the raw materials are placed in the factory area is not standardized; the raw materials and semi-finished products are placed in disorder; the semi-finished products are placed in disorder, and there is no display mark; It is mixed with the finished product of another company; the position of individual inspection instruments and equipment is not convenient for inspection personnel to operate.

9. Poor production environment and others: There is a damage to the production line in the plant; air-conditioning damage cannot guarantee the experimental temperature; the glass in the laboratory environment is damaged; there is debris in the factory inspection area.
