READ MOREIn the nearly 20 years of development of our company, we have always been committed to technological innovation and quality improvement. Through introduction and independent research and development, we now have a series of advanced production equipment and workshops, including a full set of advanced testing equipment, fully automatic upper auxiliary machine mixing system, intelligent mold library and intelligent vulcanization workshop. The investment and use of these high-precision equipment and intelligent workshops not only greatly improve production efficiency, but also ensure the stability and consistency of product quality, and deeply reflect the core concept of ""quality is the life of hundreds of millions of people"". The company unswervingly implements the quality policy of ""quality as the life of the enterprise, high quality and high efficiency"" and ""customer attention, continuous improvement"", takes detail management as the principle and lean production as the means, and establishes a full-chain quality management and control system covering raw material procurement, production and processing, finished product inspection to after-sales service, providing the market with many high-performance and high-reliability products, among which automotive rubber products are one of our star products.
The production of automotive rubber products is a complex and delicate process, the core of which lies in the selection and control of molding technology. The main molding processes used by our company include injection molding, compression molding and blow molding. For different types of automotive rubber parts, we will flexibly select the most suitable molding technology to ensure that the product meets the best performance standards.
Injection molding: This process is suitable for the production of rubber products with complex shapes and high dimensional accuracy requirements, such as seals and some suspension system components. The preheated rubber material is injected into the mold cavity by high pressure, and the finished product is obtained after rapid cooling and curing. This process has strict requirements on parameters such as rubber fluidity, mold temperature, injection pressure and injection speed to ensure the accuracy and surface quality of the product.
Compression molding: It is suitable for the production of rubber products with larger areas and uniform thickness, such as some tires and shock absorbers. This process places the preheated rubber in the mold, applies pressure by closing the mold to fill the mold cavity with the rubber, and maintains it at a certain temperature and pressure for a period of time until the rubber is completely vulcanized and formed. The key control parameters include mold temperature, vulcanization time, vulcanization pressure and preheating temperature of the rubber. The precise control of these parameters is crucial to ensure the physical properties and dimensional stability of the product.
Blow molding: It is mainly used to produce hollow rubber products, such as certain specific pipes and airbag components. This process injects high-pressure gas into the preheated rubber tube to expand it and fit the inner wall of the mold, and then vulcanizes it to shape. The key to blow molding is to control the air pressure, blowing speed, mold temperature and vulcanization cycle to ensure the uniformity of the wall thickness and structural strength of the product.
To ensure the quality of automotive rubber products, we strictly control the following key parameters during the molding process:
Temperature control: including mold temperature, rubber preheating temperature and vulcanization temperature. The appropriate temperature range is crucial to promote the cross-linking reaction of rubber molecules, improve the physical properties of products and ensure dimensional stability. We use an intelligent temperature control system to accurately adjust the temperature according to the characteristics of different rubber materials to ensure that the temperature control of each link is within the optimal range.
Pressure control: Whether it is the injection pressure in injection molding or the vulcanization pressure in compression molding, it has a direct impact on the density, dimensional accuracy and uniformity of the internal structure of the product. We use advanced pressure sensors and control systems to monitor and adjust the pressure in real time to ensure that the product meets the mechanical properties required by the design.
Time control: Vulcanization time is one of the key factors affecting the performance of rubber products. Too long or too short vulcanization time will lead to a decrease in product performance. We use the precise timing system in the intelligent vulcanization workshop, combined with the characteristics of rubber materials and product design requirements, to set a reasonable vulcanization cycle to ensure that each batch of products can achieve the best performance.
Material selection and proportioning: The performance of automotive rubber products depends largely on the rubber materials used and their formulas. We select high-quality rubber raw materials, such as polymer rubber materials, and combine them with advanced mixing technology to ensure the uniformity and stability of the rubber. At the same time, according to the application requirements of different products, the proportion of fillers, plasticizers, vulcanizers and other ingredients in the formula is adjusted to achieve the best physical and chemical properties.
With advanced molding technology, strict parameter control and a complete quality management system, our company produces automotive rubber products that not only have excellent elasticity, wear resistance and anti-aging properties, but also can effectively cope with various complex road conditions to ensure the safe and stable operation of the car. Whether it is a suspension system, seals or tires, we can provide a variety of specifications and models to meet the personalized needs of different models and customers.
