With the increasing of industrial construction, castor application market increasingly strict with the quality of the product. Industry experts point out that, in the face of high demands of the market, castor manufacturing enterprises should actively adjust the product structure, strengthen the concept of quality in the process of product design, production, manufacture, insist on & other Quality first & throughout; The management policy. Castor interaction relationship between the quality of the product and cost, be in usually, high quality heavy duty castor products is built on the basis of high cost, the cost is the premise condition, the quality is the result. But sometimes enterprise high costs is caused because the product quality is bad. One is in the process of production scrap loss and repair cost to increase the product cost. 2 it is associated with poor quality unstable product quality, make the maintenance service after the products are sold out the cost.

Above all, keep product quality, reasonable is to a great extent, control the cost of the product, to ensure the product's price advantage. As a professional production of castor wheels, industrial caster, casters and other products manufacturers, wanda industry think, ensure the reasonable product quality is the key to design and development stage, enterprise should according to consumer demand and purchasing power for product design and production, to maximize meet market demand, enhance the core competitiveness.
