The raw material of metal hose plays a significant role in the braided water hose manufacturing of metal hose products, laying a solid foundation for ensuring the quality of metal hose products. Metal high temperature hose has been widely recognized in the market; however, as the market competition of metal high temperature hose gets fiercer and fiercer, a few profit worshipping dealers and manufacturers launch metal high temperature hose of lousy quality in the market. On the other hand, certain qualified manufacturers result in releasing metal high temperature hose of bad quality in the market due to regulatory loopholes and other reasons. These unqualified products might incur sever danger and security risk during the manufacturing and application process, classified as the culprit of security risks of the product. In addition, the insufficient control of raw material purchasing process will also directly influence the quality of the high temperature hose. A variety of raw materials are needed for braided rubber hose manufacturers and different raw materials play different role in affecting the quality of the products. To facilitate the critical quality control of the purchased raw materials, the raw materials should be categorized and managed according to the different influence degrees of the raw material toward the quality of the products. Practical events indicate that the stability of the purchased raw materials is decided by the quality management efficiency of the suppliers to a very large degree. Therefore, purchasers are advised to conduct evaluations toward the quality assurance capability of the raw material suppliers before fulfilling the purchasing activity. Qualified raw material suppliers should be chosen based on rational selection. Ascertaining a qualified raw material supplier should be supported by elements such as the result of quality assurance capability evaluation of the supplier, manufacturing and application situation, price and reputation. Hence, purchasers are recommended to compare different suppliers of the same raw material, particularly when the manufacturing, application situation and quality assurance capability of these suppliers are equivalent, before finally ascertaining the supplier. Periodic analysis of the quality of raw material procurement is an important yet often neglected procedure by many metal hose manufacturers. Periodic analysis of the quality of raw material procurement could enable the users to better control the quality of the next manufacturing process and provide important information and evidence for the selection and adjustment of suppliers in the future. All in all, metal spiral hose manufacturers should not only focus on the manufacturing process and profitability of the products but also the quality of the purchased raw materials. The product quality of the metal hose manufacturers could not be solidly assured and reliably guaranteed unless the quality of the purchased raw material is well managed and the quality control procedure of the purchasing activity is strengthened.
