The following is a case study of some defective rubber products:
1. Defective rubber seals
When a company produces rubber seals, due to improper control of process parameters, the product hardness is high, and it is difficult to smoothly insert the sealing slot during installation, resulting in a decline in sealing performance. In addition, due to the unstable quality of raw materials, the product size is unstable, and the sealing effect cannot meet the requirements.
2. Defective rubber hose
When a company produces rubber pipes, due to the uneven material of the pipes, the pipes are deformed when subjected to pressure, which affects the service life and performance. In addition, due to improper temperature control in the production process, the surface of the pipe appears burnt, spots and other undesirable phenomena.
3. Defective appearance of rubber products
When a company is producing rubber products, due to unreasonable mold design or improper processing technology, the appearance of the product surface appears convex, mantle, damage and other adverse phenomena, affecting the beauty and service life of the product.
4. Poor physical properties of rubber products
When a company produces rubber products, due to improper material selection or insufficient production process, resulting in poor physical properties of the product, such as low hardness, insufficient elasticity, poor aging resistance, etc., affecting the service life and performance of the product.
5. Poor chemical properties of rubber products
A company in the production of rubber products, due to improper material selection or insufficient production process, resulting in poor product chemical properties, such as acid and alkali resistance, poor oil resistance, affect the service life and performance of the product.
According to the above case analysis, the following measures can be taken to improve the quality of rubber products:
① Strictly control the quality of raw materials, select the appropriate filler and type to ensure the stable performance of raw materials;
② Strengthen the manufacturing process control, strictly implement the operating procedures of mixing, calendering, extrusion and other links to ensure uniform product density, no porosity, cracking and other problems;
③ Optimize the mold design to ensure that the mold size and structure are reasonable, and reduce the product size deviation and surface defects;
(4) Improve the environmental resistance of the product, improve the temperature resistance, weather resistance and aging resistance of rubber products by improving the formula and production process;
⑤ Strengthen communication and coordination with customers, understand customer needs, reasonably develop production plans and quality control standards to meet customer requirements.
Through the implementation of the above measures, the rate of defective rubber products can be reduced and product quality and customer satisfaction can be improved. At the same time, enterprises can also strengthen the construction of quality management system, introduce advanced quality testing equipment and technology, achieve comprehensive monitoring and continuous improvement of product quality, and improve the comprehensive competitiveness of enterprises.
