Roto-molding Brings New Vitality To The Automotive Manufacturing Industry
In recent years, the development and innovation of roto-molding molds have brought many advantages to the automobile manufacturing industry:
1. The mold is easy to form, making it very convenient to process parts with complex shapes. For example, the instrument panel is processed with steel plates, which often requires the processing of various parts first, and then assembled or welded with connectors, which requires many processes. The use of molds can be formed in one go, with short processing time and guaranteed precision.
2. The biggest advantage of the application mold for automotive materials is to reduce the weight of the car body. Lightweighting is the goal pursued by the automotive industry, and roto-molding molds can show their talents in this regard. The general specific gravity is 0.9~1.5, and the specific gravity of fiber-reinforced composite materials will not exceed 2. Among metal materials, the specific gravity of A3 steel is 7.6, brass is 8.4, and aluminum is 2.7. This makes the mold an excellent material for lightweighting automobiles.
3. The elastic deformation characteristics can absorb a large amount of collision energy, have a greater buffering effect on strong impacts, and protect vehicles and passengers. Therefore, modern cars use plasticized dashboards and steering wheels to enhance the buffering effect. The front and rear bumpers and body trims are made of mold materials to reduce the impact of objects outside the car on the car body. In addition, the rotational molding mold also has the function of absorbing and attenuating vibration and noise, which can improve the comfort of riding.
4. According to the organizational composition of the mold, by adding different fillers, plasticizers and hardeners to make molds with the required performance, the mechanical strength and processing properties of the material can be changed to meet the use requirements of different parts on the car. For example, the bumper must have considerable mechanical strength, while the seat cushion and backrest must use soft polyurethan
5. It has strong corrosion resistance and will not corrode if it is locally damaged. Once the paint surface of steel is damaged or the initial anti-corrosion is not done well, it is easy to rust and corrode. The corrosion resistance of the rotational molding mold to acids, alkalis, salts, etc. is much greater than that of steel plates. If the mold is used to make the body cover, it is very suitable for use in areas with greater pollution.
In general, the rotational molding mold has begun to develop from ordinary decorative parts to structural parts and functional parts in the field of automotive applications; the material is developing towards composite materials and mold alloys with higher strength, better impact resistance and ultra-high flow.
