Geared Motors for
the Rubber &
Plants and machines in the rubber and plastics industry have to withstand enormously high loads. Gearboxes and geared motors serve to drive these plants and machines and are used in stretching equipment, plastic kneaders or film drawing lines, to name just a few examples.
Rubber is used in the manufacture of car tyre, vehicles and machines and is a component of seals, rubber boots, erasers and much more. Plastic is also used in various other industries such as mechanical engineering, construction, automotive, electrical engineering and packaging. Plastics also play an important role in the food and beverage industry. As a result, both rubber and plastic have become indispensable nowadays.
In order to enable rubber and plastic manufacturing companies to operate smoothly in the process chain, you need high-quality and high-performance gearboxes and geared motors. You will find an insight into possible areas of application in the applications below. If you do not find what you are looking for, please contact us. Our engineers are looking back on decades of experience in the field of design and are the ideal contact when it comes to providing you with a tailor-made solution.
Rubber & Plastic
Hollow bodies made of polyethylene, polypropylene and other plastics are produced by rotational moulding. The rotation mould is filled with the plastic granulate and heated during rotation. The material melts and settles on the mould walls due to the rotational forces. The mould is then cooled from the outside by large fans and kept in rotation until the material has cooled down. In this way, containers such as plastic tanks, but also other shaped bodies such as mudguards, plastic furniture, tubs and flower pots are produced.
Extruders are machines that produce bar- or sheet material from a viscous, usually hardenable mass. The mass is pressed through a shaping opening and gets the cross-section of the opening. The pressure is often generated by a screw (screw extruder), bodies of any theoretical length can be produced. Flat gear motors are often used as drives, Premium Stephan offers a wide range of these.
Calenders consist of several heated rolls arranged one above the other, between which a viscous, often molten mass is passed through. The material is rolled to the desired thickness in several stages, then cooled and wound up. The process is used for the production of foils, but is also suitable for coating foil-like materials. Premium Stephan has an extensive range of geared motors to drive the rollers.
