Take quality as the guide, implement technological innovation, follow the ISO9001 quality management principles, promote comprehensive quality management, and become a trusted partner of customers.
Raw material quality control uses 99.7% pure aluminum ingots to produce aluminum rods. During the aluminum rod production process, online degassing to ensure that the hydrogen content of the aluminum rods meets the requirements of the OPC drum base. At the same time, Japan Mitsui original tubular filtration is used. The equipment performs slag removal to ensure that the impurity content of the aluminum rod meets the requirements of the OPC drum base;
According to the GB3246 specification, the aluminum rods are subjected to low-power microstructure examination and metallographic analysis to ensure that the quality of each batch of aluminum rods used for OPC drum base production meets the requirements. Drum-based process quality control According to the principle of batch management, each batch is used as the production unit, from extrusion to finished product shipment, through process confirmation, size assurance, performance testing and other means, quality control of each batch of production process.
During the extrusion process, an intermediate frequency electromagnetic induction heating furnace is used to accurately heat the aluminum rods. The PLC system is used to automatically control the extrusion speed to achieve single-bar isothermal extrusion, while ensuring that each bar is in the same process Extrusion under conditions will eventually achieve uniformity and stability of product mechanical properties. In view of the high requirements of OPC aluminum tubes in terms of dimensional precision, processing stability and surface quality after anodizing, combined with the characteristics of the equipment, the suitable extrusion process is adjusted, and the frequency conversion stretching machine is used for tube stretching. The entire stretching process is precisely controlled to achieve precise and controllable dimensions of the extruded billet tube after stretching, and at the same time allows the final product to obtain a good surface condition after anodizing by the customer.
Systematic production process
With the goal of surpassing customer needs, we continue to improve manufacturing capabilities and improve equipment support.We have two extrusion production lines of 630T and 1000T, imported stretching machines, multi-roller straightening machines, automatic sawing machines, CNC and other precision processing machinery In addition, it has large-scale third-party manufacturers covering anodizing and spraying surface treatment capabilities to provide customers with complete product solutions. We adhere to the concept of quality first, select the most suitable inspection and testing equipment to carry out inspection and testing in the process of product realization, equipped with metallurgical microscope, pneumatic measuring instrument, video measuring instrument, roundness detector, various hardness testers, materials Testing machine, etc. We are equipped with a dedicated QC team, adhere to the implementation and implementation of the relevant requirements of the ISO9001 system to meet customer requirements, meet the requirements of laws and regulations, and continue to improve and pursue excellence.
