Mercedes-Benz utiliza PEEK para reemplazar engranajes metálicos
Evonik has recently developed a PEEK molding compound with high friction performance and high durability. Gears made of PEEK can meet the harsh application environment of internal combustion engines and replace metal gears. It is understood that there is a component in the internal combustion engine called a mass balancer, which ensures the smooth operation of the internal combustion engine by reducing the vibration caused by the piston on the surrounding structure. The mass balancer gear is often in contact with the engine oil and exposed to high temperatures of up to 130 degrees Celsius, and is usually made of metal. PEEK is now used to manufacture low-wear outer ring gears for plastic gears in mass balancers. This…

Cómo calcular el peso de una varilla de PEEK
La fórmula de cálculo del peso de la varilla de PEEK es: masa = volumen x densidad. La densidad del PEEK puro es aproximadamente 1,3 y la del PEEK modificado es aproximadamente 1,4. Sin embargo, cabe señalar que el diámetro exterior de la varilla de PEEK es generalmente mayor. la calibración, por lo que el peso de una sola varilla debe basarse en el diámetro exterior real.

Molde de precisión para inyección de PEEK para medicina deportiva
Since the 1970s, joint surgery has made great progress in the United States and other countries. In the past few decades, arthroscopy has had a revolutionary impact on the diagnosis and treatment of intra-articular diseases. However, the first generation of shoulder arthroscopy equipment uses stainless steel and titanium anchors, both of which will fail due to the breakage of the sutures in the metal eyelets. For this reason, the medical device industry has made many attempts and designed a variety of injection molded products – implant-grade PEEK anchors. PEEK is strong and tough, and can provide strength similar to that of metal. If a revision surgery is required, it can be drilled through without increasing the difficulty of the surgery….

Las pruebas PEEK de Junhua cumplen con la TSCA
PRRT 01. Definition and History of TSCA TSCA stands for Toxic Substances Control Act, or TSCA for short. It was enacted by the U.S. Congress in 1976 and took effect in 1977. The U.S. Environmental Protection Agency (EPA) is responsible for its implementation. The Act aims to comprehensively consider the environmental, economic and social impacts of chemical substances circulating in the United States and prevent «unreasonable risks» to human health and the environment. After several revisions, TSCA has become an important regulation for the effective management of chemical substances in the United States. For companies whose products exported to the US market fall into the TSCA regulatory category, TSCA compliance is a prerequisite for normal trade in US products. These…
