According to Bridgestone News, as its flagship brand for “ green tires †environmental protection, sales of “ green song partners †in the Chinese market have now exceeded one million. In March 2010, the "green song partner" was the first flagship product to introduce the Chinese market to EP100A. Thanks to the "ECOPIA compound" technology, which is a special modified polymer and carbonized product, this product achieves a 20% to 25% improvement in tire rolling resistance, taking into account product safety and environmental protection (energy saving and fuel saving). . In recent years, with the deteriorating global environment, more and more families and individuals have begun to pay attention to the environmental protection details around them. As the only carrier for the contact between the car and the ground, the tire becomes an important environmental factor that cannot be ignored. According to reports, the "green song partner" low rolling resistance technology, to ensure its energy-saving and environmental protection characteristics, taking into account the safety advantages of wet road braking, but also allow it to be widely concerned about in the industry. According to industry sources, the popularity of the tire brand in the market has witnessed the increasing awareness of the public's environmental awareness. In 2012, with the launch of the first green tire SUV EP850 in the Chinese market, the first green song companion R102 for China's commercial vehicle sector was launched, and its product line in the Chinese market was getting more and more. rich.
According to the classification of forging process, closed die forging and open die forging are commonly used. Closed die forging generally keeps the gap between the upper die and the lower die during the forging process, and the material is formed in the closed die cavity around it. Generally, no flash is generated. A small amount of excess material will form longitudinal flying spurs, and the flying spurs can be removed in subsequent steps. Closed die forging improves the dimensional accuracy and surface quality of the product, reduces flash, and improves the utilization of materials.
SCZY mainly produces hot forging products, both closed die forging and open die forging are produced, which can depend on the requirements of the product. Whether it is closed die forging or open die forging, we will fully consider it during mold development to reduce the occurrence of defective products in the production process. Our own internal mold manufacturing, forging production and subsequent secondary CNC machining can cooperate with each other, which can better ensure product quality and production delivery.
