2018, the quality of the plate heat exchanger needs to be strictly 3. Why must we tighten the 3? Believe that friends in this field know, because of the particularity of heat exchanger products, if encountered product quality problems, go to the customer where inspection, maintenance or replacement, is a very troublesome thing; and a person on a business trip to do after-sales, may not be settled; at this time you need help, if no one can help you, guest There are time limits on which side of the household, specifying when it must be used, and once the prescribed time frame is not completed, this is bad, and will seriously affect customer feelings, word-of-mouth and product reputation. So. The quality of plate heat exchanger products must be super-hard, do not appear any abnormalities or failures; to establish 0 fault, 0 after-sales, improve the overall product quality and quality awareness.

So, what is the 3 hurdle? They are "material procurement (IQC / quality control), production process monitoring (IPQC / process control), factory inspection (OQC / quality inspection)." These three barriers are any manufacturing products need strict control; on the contrary, products without quality, the enterprise has no future.

1. Material procurement and quality inspection of outsourcing products.

(1) Material purchasing of plate heat exchangers and stacking of outsourced products in the waiting area or designated area after entering the company shall be self-checked and checked by the personnel in charge of the quantity, specifications and models, appearance quality and accessories.

(2) After checking and verifying the correctness of the materials, the material handler fills in the inspection form, which requires accuracy and detail. Remarks should be made on the special materials, together with the material drawings, equipment details and other relevant documents, and submits them to the inspector for inspection.

(3) Inspectors shall collect data, inspect quality and fill in inspection reports for materials and outsourced products according to the contents of inspection forms, mark the status of quality inspection, and clearly mark the inspection results on the inspection forms.

(four) the handling personnel shall go through the warehousing procedures according to the material inspection results of the heat exchanger. Unqualified isolation and take return, replacement, rework, maintenance and other methods to deal with, after self-inspection qualified re-implementation of inspection procedures.

(5) The quality control department is responsible for tracking the material quality of the plate heat exchanger of the test pieces and provides them to the supply department in time.

(6) Inspectors shall follow up and trace back the disposal of unqualified heat exchanger materials in time, find out the causes of the problems and solve them in time.

(7) Warehouses and any other users shall not accept unqualified plate heat exchanger materials or outsourced products.

Two. Production process monitoring and control (IPQC/ process control)

(1) IPQC/process control refers to the quality control of the product from the material put into production to the final packaging process. IPQC is also called process quality control, or quality control in the production process, the English full name is InPut Process Quality Control. IPQC is also called patrol inspection, because the inspection method adopted by IPQC is to inspect between the various processes in the production process.

Generally, sampling inspection is adopted. The inspection contents are generally divided into sampling inspection of the product quality of each process, inspection of the operation methods and methods of the operators of each process, and spot inspection of the plate heat exchangers in the control plan.

(two) IPQC method:

1. carry out process audit according to the audit list - the basic state of the process does not depend on the plate heat exchanger products.

2. process operation inspection - plate heat exchanger material, tools, accessories, methods, personnel confirmation.

3. the first part confirmation inspection depends on the product and the different process, equipment, software and parameter checking.

4. record - true, clear and timely.

5. feedback mechanism between processes: timely feedback of relevant information.

6. the early warning mechanism plays a role.

7. control of nonconforming product identification, isolation, differentiation and statistical analysis.

8. Material Input for Plate Heat Exchanger - Put the right material into the right product at the right time, and record it timely and accurately for easy traceability.

9. product standard -- process standard and function requirement.

10. sampling inspection for each process, confirming the stable process, full capacity and qualified products.

Three, factory inspection clearance (OQC/ shipment quality inspection)

(1) OQC/Shipping Quality Inspection refers to the quality inspection/quality audit and control of plate heat exchanger products prior to shipment, mainly for the packaging status of the shipped products, collision-proof materials, product identification/safety labeling, Accessory Kits, manual/warranty, additional software CD-ROM, product performance testing report, outer box Labels and so on, do a comprehensive check and confirmation, to ensure that the customer receives the goods and the agreed content conforms to, in full compliance with the mode of shipment.

(2) OQC process of plate heat exchanger, production and inspection - OQC sampling according to sampling standards - inspection according to shipment standards - qualified warehouse - unqualified bills of return, if the urgent need for shipment, the relevant departments to apply for special approval to the relevant departments for review, if it is not urgent or can not be specially collected, then rework, rework after rework Re-inspection; the entire process needs to be strictly controlled, so the quality department and the production department, to do a good job of coordination, timely treatment of abnormal quality plate heat exchanger products.

To sum up, it is better to import ISO9000 into the quality management system for the quality control of plate heat exchangers; according to the requirements of the quality management system, the ISO9000 series standards have been formulated by the ISO9000 Quality Management and Quality Assurance Technical Committee of the International Organization for Standardization (ISO) to apply to different types, products, scales and properties of organizations. The standard is composed of a number of interrelated or supplementary individual standards, of which the ISO 9001 Quality Management System Requirements is well known. The requirements put forward by the standards are complementary to the requirements of the products, which have been revised several times. On the basis of this standard, different industries have formulated corresponding technical specifications. Quality control of plate heat exchanger products, if can fully organize the quality management system team; then, to create first-class product quality, is hopeful.

The quality of plate heat exchanger is stable and reliable, which has won the unanimous approval of our customers. We believe that soon, our products will be able to enter the international vision and become internationally recognized plate heat exchanger products.
