The proportion of materials cost to total production cost for O ring may vary from different manufacturers, but it should be controlled within a certain range. The material cost includes the direct materials consumed in the manufacturing process, auxiliary materials, purchased semi-finished products, and others. Generally, the material cost should account for 1/3 or 1/4 of the total cost because the quality of the materials determines the quality of the finished products to some extent, and to get high-quality and certified products, it requires a company adhering to integrity and honesty to put a certain amount of investment in purchasing reliable raw materials.
