A global scientific company active in the fields of health, nutrition and materials. Royal Dutch DSM Group, its Stanyl ® PA46High temperature resistant, low wear plastic gears have been used worldwide 2Actuators for more than 100 million cars, such as electronic throttle control (ETC ) Actuator, Exhaust Gas Recirculation System (EGR ), Turbine, Universal Actuator (GPA ) Actuators and variable intake systems, and successfully demonstrated its reliable performance and cost-effectiveness.
With the rapid development of science and technology, product design freedom has increasingly become the focus of attention in the field of industrial design, especially for the automotive industry, especially actuators. Traditional metal gear often can not meet the actuator to design freedom Degree and rapid upgrade requirements. Plastic gears have a good design flexibility, lightweight, based on one-piece molding low cost, wear resistance, lubrication-free operation, low noise, etc., get more and more widely used.
The global scientific company active in the fields of health, nutrition and materials has successfully established a leading position in the field of plastic gears for the Dutch Royal DSM Group's material solutions. Its Stanyl® PA46 has been used in the actuators of more than 200 million vehicles worldwide. Such as Electronic Throttle Control (ETC) Actuators, Exhaust Gas Recirculation System (EGR), Turbine, General Purpose Actuator (GPA) Actuators and Variable Intake Systems, and successfully demonstrated its reliable performance and cost effectiveness. The use of Stanyl® PA46 as a substitute for metal saves costs by more than 40%; Stanyl® PA46 has a density of only one-seventh that of steel, and Stanyl® PA46 is a complete gear set whose weight is only that of metal gear sets. 40-60%; and its noise and carbon emissions are also lower, for a midsize sedan, the use of Stanyl® PA46 instead of metal gears, can reduce the carbon emissions of 0.06 grams per kilometer.
Stanyl® PA46 provides excellent abrasion wear performance, especially at high temperatures and dry friction, and can reduce wear by up to 50% compared to high performance materials such as PPA, PEEK, PA66, thus greatly improving the durability of the gears When used in gears in motor management actuators, the life of the gear can be extended to three times the standard (40 million load cycles).
High-speed or high-ambient operating conditions impose high temperature requirements on gear materials. POM materials are incapable of performing at long-term temperatures above 100°C or short-term temperatures above 140°C. Compared with POM, Stanyl® PA46 has better temperature resistance and is especially suitable for high temperature applications such as intercooled integrated electronic throttles.
Material selection and design of gears are inseparable. DSM's professional technical team not only has a solid material experience, but also has accumulated rich experience in gear design practices, while providing gear manufacturers with innovative material solutions, but also In the gear structure design, mold design, production process optimization and other aspects to provide comprehensive technical support.
In addition to Stanyl® PA46, DSM also has a wide range of material options to provide overall material solutions for the friction pair of gears, and to provide a variety of PBT, PA, PPS and other materials suitable for the manufacture of actuator housing.
