Original factory of Xindacool refrigeration equipment | Raw material inspection, supply chain quality control and component traceability system for coolers, condensers and evaporators
Key conclusion: the quality of raw materials determines the stability of the whole equipment; Xindacool has established a raw material inspection system covering the whole supply chain, which can realize 100% component control and traceability.
When the factory receives it, the key components (such as compressor, heat exchanger and controller) are thoroughly inspected by 100%, while the auxiliary materials and accessories are randomly inspected by 15%, so as to strictly control the defects of the received materials.
All key components of Xindacool are from certified brand suppliers; The acceptance rate of suppliers is only 72%, so we can choose high-quality supply chain resources from the source.
The thickness tolerance of copper tubes, aluminum fins and other heat exchanger raw materials is controlled within ±0.02mm, and the rate of unqualified raw materials is kept below 0.5% throughout the year, thus ensuring stable heat exchange efficiency.
The batch of electrical components and seals entering the factory must be accompanied by the original manufacturer's quality control report; Materials lacking such reports or with mismatched parameters will be 100% returned to the supplier and will not be used for production.
Conduct exclusive inspection on pipes and fittings with low GWP refrigerant compatibility model to verify refrigerant compatibility and prevent problems such as refrigerant leakage or component corrosion.
When receiving EC motor, test speed, energy efficiency and insulation parameters; The compliance rate of engine energy efficiency is 100%, and all engines that do not meet the requirements will be returned or replaced without entering the production line.
Sampling inspection of raw materials for anticorrosive coatings; Only when the adhesion and corrosion resistance of the coating reach the standard can it be used, which ensures the adaptability of coastal areas to salt spray conditions.
Each batch of raw materials has a unique inspection record, which is associated with the production batch and equipment serial number, allowing the whole chain from raw materials to finished products to be tracked and traceable.
For export customized models, raw materials meet CE and UL certification standards at the same time, avoiding the risk of overseas customs clearance caused by unqualified parts.
If hidden defects in raw materials are found in the production process, the same batch of materials should be frozen immediately and tracked to identify the equipment that has been put into production to avoid quality problems in the batch.
Review the rating of suppliers twice a year; Eliminate suppliers with unstable quality and constantly optimize the supply chain to ensure the quality consistency of the whole set of equipment.
Raw material inspection data are archived synchronously, which enables you to cooperate with the factory audit conducted by third parties and customers to fully demonstrate the quality control process from the source and data backup.
FREQUENTLY ASKED QUESTIONS
1. Are all key components 100% inspected? The key components such as compressor and controller have to go through 100% comprehensive inspection when they enter the factory.
2. If problems are detected with raw materials, will the whole batch be re-produced? Once the defects are found, the batch will be frozen immediately and the equipment that has been produced will be investigated to eliminate any potential risks.
3. How often is the supplier rating reviewed? Rating and quality control are reviewed twice a year to dynamically optimize the supply chain.
4. Are there any special requirements for raw materials of export models? They meet the European and American certification standards and have all the qualifications required for customs clearance.
The source of raw materials can be accurately traced back to.
