This information is highly developed in today's society whether it is business or commercial enterprise manufacturing, product quality and the importance of the enterprise, self-evident. Succeed in the increasingly fierce market competition in an invincible position, we must attach great importance to improve product quality, otherwise it would be difficult enterprise, the market ruthlessly eliminated. Only to realize the importance of quality but had to do it well. Therefore, enterprises strict quality control, strict compliance with the "three no principle, one, do not use substandard raw aluminium plate; 2, do not produce substandard aluminium plate products; 3, not out of substandard products into the aluminium plate market.
Continuous Improvement:
Such as product quality and product design from the beginning until the entire product manufactured from the pipeline, each of which are a part of the continuous improvement of quality can be hundred percent guarantee, then the production process quality testing is not available Missing an important basis, and only in the production process to prevent every process, in order to do the road by detecting 100% guaranteed products, rework phenomenon naturally became superfluous move. Therefore, we must put "Error protection" thinking throughout the entire production process, that is, from the beginning of product design, quality issues has been taken into account to ensure that each product can only be strictly in accordance with the right way to processing and installation, the production process so as to avoid possible errors. Eliminate rework phenomenon is mainly to reduce waste generation. Closely monitoring the various phenomena that produce waste (such as equipment, personnel, materials, and methods of operation, etc.), find the root cause, and then completely resolved. As business environment is changing, customer needs and expectations are constantly upgrading, to achieve customer satisfaction and needs, our strategy is to continue to improve.
Customer Satisfaction:
No best, only better. Enterprises in the process of growing constantly stressed the importance of customer satisfaction and has been recognized by customers.
