We are the experts when it comes to the production of plastic parts using the rotation process. This method aims to give plastics the desired shape with the aid of machine-driven rotation. State-of-the-art, computer-controlled rotary systems process the raw material. This results in decisive process and product advantages.
The process in detail – to the finished plastic part in just four steps:
The rotary process for the production of plastic parts
Initially, a pre-weighed amount of plastic powder is filled into half of a thin-walled, hollow metal mold (tool) mounted on the processing machine’s mold carrier (rotating arm). The mold parts are then joined together and sealed.
The mold is moved into the furnace and set into bi-axial rotation by the rotating arm and turntable. In the stove, controlled heat from outside penetrates the mold wall. The material in the mold is continuously heated, the material particles melt on the hot mold wall and form a new layer, the molded part wall.
After all the material has melted and consolidated into a wall, the machine moves to the cooling station’s next position, where the component still in the mold is cooled below the crystallization point. Meanwhile, the bi-axial rotation continues to prevent the melt from running off…
After sufficient cooling, the machine moves to the so-called demolding and loading station, where the mold is opened and the finished part is removed.
The result of the procedure:
a light, robust and high-quality plastic part
Maximum efficiency and precision: the advantages of the rotary process
The rotation process is highly efficient. The precise, computer-controlled rotary systems are mainly used for the production of large-volume parts. The advantage: The virtually pressureless process is ideally suited to manufacture products that are primarily free of stress. This keeps the final product very tolerant of pressure and impact. In addition, the product has a light dead weight. Compared to other processes, the low tooling costs enable the economical production of minimal series of fewer than 500 pieces up to medium-sized series of 10,000 pieces p.a. To ensure the high quality of our end products at all times, we use finely ground plastic powder as raw material. The plastic powder is selected according to the desired color and shape on a customer- and project-specific basis.
Our raw material portfolio includes PE, PA6, PA12, PP and XPE, among others.
Top-quality at reasonable prices
The rotary process is not only efficient but also very economical – initialization costs for molds and fixtures are usually much lower than other processes such as deep drawing, blow molding or injection molding. As a result, changes can be made cheaply and quickly. Added to this is a common maintenance requirement. The end products also speak for themselves – low-stress, seamless, corrosion-free parts, shock- and impact-resistant plastic. In short, a quality product that can withstand any pressure and even extreme temperatures. The integration of metal and plastic components is also possible without any problems. There are virtually no limits to product design in terms of design and color – thanks to our in-house mills and turbo mixers, we can also produce customized powder mixtures at short notice and in small batches if required.
