Production Management System and Quality Control

Production Management System and Quality Control

We use ISO standard, zero defects& 5S management system.


                                                                                                                      ORGANIZATION CHART

1.1 Project evaluation & review

When receive a new order, vice manager will organize sales, technical,procurement& logistics depart to evalue the production cycle, processing requirement, technical requirement, material supplies and other aspects to get a comprehensive analysis. Meanwhile, we should evaluate the manufacture difficulties,technique focus and product cycle therefore to make some reasonable decisions for the project that the organization, coordination will be ok to ensure the successful completion of each project.

1.2 Weekly and daily meeting

All of departments will have a meeting on Saturday morning 9a.m to review the problems that happened in the last week and arrange for the coming week. We will discuss and solve them. Every department should strictly execute the meeting decision.

1.3 ERP Management System

Based on the manufacturing process, it can achieve the recording and controlling of the technology loft, ingredients, optimize the cutting of raw materials, the whole process of production,dispatch of goods,logistics via scanning the the bar code and collecting data in the process flow card. We are able to trace the whole process of manufacture and calculate the output at anytime accurately, analysis the work efficiency, consumption of raw material,operation of the equipment and the storage for set of tower with the real time data. These can help us to make right decision in the procedure and greatly enhance our efficiency and enterprise management.


2. Quality Control

Quality is the life of our enterprise.The quality management is always the core in our company in the past more than 12years.We have passed the ISO 9001:2008 quality management system. The quality management system covers raw material control,production process control ,special technology control and the records of the all processes.

2.1 Raw material control

We have the chemical & physical laboratory which are certified by state grid. There are more than 20sets of professional equipment for test and detection. Therefore, we can do the chemical elements and mechanical properties by ourselves.All of the raw materials can’t be used until finished the yield strength test, tensile strength test,elongation test,cold bending test and five elements experiment analysis(C,S,Mn,P,Si). The raw materials will be accepted only if the results are in accordance with GB standard.

2.2 Quality control during production procedure

While incoming QC guards inferior components from going into production lines,outgoing QC reassures that only qualified products leave our factory. 100% quality checking is carried out at our offline W-Inspection line to guarantee zero-defect items. Every Production process is equipped with full-time quality inspector. They have to inspect all of the parts’ dimension and accuracy according to national standard or international standard to ensure all of the parts are okay to go to next process. And the inspector should calculate the quantity of each bundle according to the packing list to make sure the quantity is right ,packing properly and the surface is smooth.

2.3  Special technology control

There are six technicians who are in charge of the welding, assembly, bendingdigginground edge and galvanization in the workshops.All of the units have to be rechecked by them after the inspection by inspector who is from the quality department and then to the next process.

2.4  Quality control records and archiving

To make sure of the traceability of all the products, we keep the records of the purchase and inspection of raw material, the production process, inspection, the artificial files, manufacture cards, packing list and all of the other files. We will make inspection report according to the clients’ requirement. We achieved an excellent result-the qualified rate reached 99.99% by make checks at all levels and made our effort to be the leading role in our industry.

2.5 Content and methods of Inspection

2.6 Quality plan and standards for check and accept

The QC makes the quality plan and executable files in advance, and sends them to the relevant operating procedures to ensure the goods’ quality.

2.7 Incoming goods inspection and testing

Steel products (angle steel,profiles, plate , tube and other steel)–performing the current GB standards of P.RC. It contains the D.C or records, certification, visual test,measurement test, mechanical properties (tensile strength, yield strength, elongation,cold-formed, impact energy, etc.), routine chemical composition test(C, S, Si, Mn, P) and composition of alloy elements (V, Nb, Ti).Bolt Products (bolts, nuts, washers, etc.) – performing the current GB standards of P.R.C or the standard from the suppliers. It contains the certification from suppliers, D.C and records, measurement, controlled measurement, mechanical properties testing and thickness of zinc coating test.  

Welding material -performing the current GB standards of P.R.C, it contains the certification from suppliers, visual test, chemical composition test and the mechanical properties test of welding.

2.8 Inspection and testing on black products  

Workers in each production process should check the goods according to the"three-checking". It contains the material specifications, visual test, measurement, quality and the mark. QC has to check the black products according to the inspection rules. It contains the material specifications, visual test, measurement, quality, mark and detecting test for the bending and welded goods if required. Meanwhile, we should assemble the prototypes after all of the production process as per the design and standard documents. And then make mass production after the approval of technical and quality department.

2.9 Product inspection and testing  

Galvanized products quality control – it’s tested according to the GB/T2694-2010 "Specification of manufacturing for transmission line tower ".And sometimes we should make special test plan and test according to it if the clients requires.  Package and mark –it contains the quality of the package, it’s not easy to be broken,records for the packing process, the quantity is the same as the packing list, shipping mark is the same as the requirement of clients, no rough loading.  

2.10 Inspection and testing by third-party  

If required or the terms of the contract are clearly required, third-party inspection and testing is accepted. Goods can be taken to a third party for quality inspection and test. It’s carried out by the QC from the customers’ company or the authorities who have been qualified.
