What is the responsibility of 1.IPQC?
IPQC: In process quality control, the quality control of internal processes is mainly to find, feedback and track problems in the process. Supervise the operation of employees, etc.
Second, the quality control department IPQC job responsibilities:
Daily work content of IPQC: 1. Responsible for the first piece confirmation of the team under its jurisdiction. A. Be responsible for the first article confirmation of each working procedure of the team under its jurisdiction. The first three products of each working procedure are the first articles, which are submitted to the team leader for confirmation after self-inspection by the operator, and submitted to IPQC for confirmation after the team leader confirms that they are qualified. Relevant results are recorded in the "First Article Preparation and Inspection Record Form"; B after the first product is sent for inspection, IPQC shall confirm the completion within 5 minutes, and mark and sign the first product. C. If the first piece is confirmed to be unqualified, it shall be re-submitted for production according to the above process. After the first piece is qualified, the process production can be carried out downwards. The first piece submitted for inspection three times in a row is unqualified, and "abnormal quality" is issued. 2. Be responsible for the process inspection of workshops, teams and stations. A IPQC shall conduct a round of inspection on each station in charge every 45 minutes-1 hour according to the sampling standard, and record the inspection results on the "Process Inspection Record Form". B, for the unqualified sampling standard, first notify the operator to stop rework, and tell the team leader to change to another station. For those who refuse to rework or do not rework as required, immediately feedback to the production manager and quality control manager. C. In the production process, if the defect rate of the same problem is ≥ 10% or the material is damaged due to operation problems, and the processing error is ≥ 5%, so it is impossible to rework, the production process shall be stopped immediately. Ipqc or the production department puts forward the quality exception list and records it on the quality exception tracking table. After being confirmed by the quality manager, it will immediately cooperate with the production department to deal with it. When the production and quality control departments can't handle it, IPQC shall submit it to the technical department for analysis. IPQC field tracking and timely feedback.
Three. Process Inspection (IPQC) Workflow and Work Contents
Process Inspection (IPQC) Workflow and Work Contents
Inspectors, also known as process inspection (IPQC), have the following working procedures:
1.IPQC personnel should know the production plan of the competent manufacturing department for the next day before leaving work every day, so as to prepare relevant inspection materials in advance.
2. Before the manufacturing department produces a certain product, IPQC personnel should know and find relevant information in advance:
Manufacturing order;
(b) Technical drawings for inspection;
(c) List of materials used in the product;
(d) Inspection scope and standards;
(e) Process flow and operation instruction (operation standard);
Records of abnormal quality;
(g) Other relevant documents;
3. When the manufacturing department starts production, IPQC personnel should assist the manufacturing department, mainly as follows:
Process flow inspection;
(b) Check relevant materials, tools and fixtures;
(c) Spot check with measuring instruments;
(d) Guidelines on quality standards for operators;
(e) Inspection records of the first inspected product;
4. Only when IPQC is qualified according to the inspection results of drawings and limit samples can it start normal production, and fill in the first product inspection report, and keep the first qualified product (the first qualified product in production judgment) as the production limit model of this batch.
5. After the production of the manufacturing department is normal, IPQC personnel will conduct patrol inspection according to the specified time. The patrol inspection time is generally specified as follows:
1 round inspection A: 8: 00 B: 8: 30 C: 9: 00 D: 9: 30 or according to a batch inspection.
6. When defective products are found in 6.IPQC inspection, the reasons shall be analyzed in time, and the irregular action sequence of the operators shall be corrected in time.
7.IPQC shall promptly cooperate with the management or technical personnel of the manufacturing department to deal with the defects of the inspection station, analyze the reasons and formulate preventive measures and preventive measures for abnormal problems.
8. If 8.IPQC can't handle major quality anomalies, it shall issue a Notice of Process Anomalies, which shall be reviewed by the production supervisor and notified to relevant departments for handling.
9. If major quality anomalies are not handled in time, IPQC has the responsibility to ask the manufacturing department to stop or stop handling, so as to prevent further manufacturing defects.
10.IPQC shall record the inspection in the process inspection record form in time, and submit it to department heads and managers every day, so as to grasp the production quality status in time.
1 1, poor control of manufacturing process.
[1] Distinguish between errors:
According to the source of bad products, it can be divided into the following categories:
(1) Poor operation
A: homework error.
ill management
C: equipment problems
D: defects caused by other reasons.
(2) Inferior materials
A: The purchased materials are not well mixed.
B: the preliminary work was not handled well.
C: Other defects obviously caused by engineering or purchased materials.
(2) Poor design
Poor solid design leads to poor operation.
Calculate the defect rate:
Manufacturing defect rate
A: manufacturing defect rate = X 100%.
total output
Original defective rate of materials
B: material defect rate = X 100%.
Material input number
Sampling quantity of defective products
C: poor sampling = X 100%
Total sampling number
