Two current examples of Dressler Group innovations: Spherical Powder Technology (SPT) and the development of integrated processes. SPT is a process that allows powders to be made out of high-performance polymers that cannot otherwise be pulverised. This opens up completely new kinds of applications, using processes such as 3D printing/additive manufacturing, that were equally impossible before. Meanwhile, integrated processes allow grinding, sieving and dust removal to be carried out in a single operation rather than separate steps, thus saving energy and time.

At our Technical Centre, which has proven its worth over many years, even the smallest quantities bring you great benefits. With an area of over 1,000 square metres, we offer the perfect facilities to verify how the raw materials will actually behave in the intended processes and finishing steps. In addition, we run scalable test series to generate reliable data for calculating costs. The process in three steps: 1. Pilot trial: testing on the smallest scale 2. Scale up trial: testing on the high-performance universal mill, with close support from our experts 3. Large-scale production: testing on the large plant for production on an industrial scale

DG Mixing process which under the application of high speeds injects enough energy into a powder quantity to create a stable compound from different types of powders and grain particles. Used, for example, for coating surfaces of one type of particle with other particles.

Recording of data and events in written form for later reference. Full documentation is important for all stages of an order. All relevant data is documented and archived, from order entry, production, quality assurance to dispatch. This ensures that the individual processes can be traced back.

We developed a special process for making fine powder systems and composites from low-viscosity melts. With the patented cryo-spraying process CSP, it has become possible to produce highly sensitive products directly from a hot melt to form a solid powder without after-cooling. The entire spraying process is overlaid with nitrogen and also protects very critical substances against oxidation and thermal stress.

DG Grinding processes with simultaneous cooling of the raw material to temperatures far below ambient temperature (e.g. minus 30°C); usually done with the help of liquid nitrogen, which has a temperature of around minus 196°C.

At our Innovation Lab, we develop entirely new processes when the desired results cannot be achieved with standard solutions. Our customers can practically watch over our shoulder and participate in the process to the extent they choose. The results are then put to the test in the adjacent Technical Centre. Sometimes this opens up whole new business areas for our customers. Getting more than they bargained for – that’s one more thing our customers appreciate.

Process of grinding and ultra fine grinding during which compressed air is blown into the grinder under high pressure through nozzles, thereby swirling and crushing the particles. Examples of our services: 1. PA12: d50 = ca. 5 µm; 2. PEEK: d50 = ca. 8 µm; 3. PPS: d50 = ca. 12 µm; 4. PA11: d50 = ca. 8 µm Let us know what you would like us to do for you!

Method for determining the grain size; air jet sieve, vibrating sieve, but also used in a production system for separating the coarse component of a powder so as to obtain the desired grain size distribution. Using acceleration to separate particles of different weights and therefore mostly different sizes.

Our international bestseller: the VX1000 is a universal 3D printer for industrial applications. The machine is fast, easy to operate and enables you to cost-effectively produce medium-sized molds, cores and models for making prototypes. The VX1000 is also suitable for producing small series. Plastic and sand can be used as the particulate material. The piezo print head system of the VX1000 achieves a resolution of up to 600 dpi. The machine's build space measures 1,000 x 600 x 500 mm. The thickness of a layer applied in one cycle is 150 µm for plastic and 300 µm for sand. In addition, the VX1000 concept is environmentally friendly: In plastic processes, the unprinted particulate material is recyclable.

Good ergonomics and optimal component accessibility Milling can be used to not only create highly complex component geometries, but also to achieve precise cutting depths. It is often used in combination with punching operations to produce component variations or small quantities, such as of instrument panels, center consoles or door panels. FRIMO FlexTrim milling machines have been specially developed to process complex 3-D plastic components. The newest generation of FlexTrim milling machines offers an attractive price/performance ratio. The new rotary table and product fixture concept ensures excellent ergonomic conditions for the operator and optimal component access for the milling robots. The use of multiple product fixtures per station reduces the number of necessary changes, thereby increasing productivity. Through the use of new milling technology with optimized chips, an effectiveness ratio of up to 95 % is possible with appropriate material combinations.
