Processing plastics - Import export

There are a variety of methods used to process plastic. Each method has its advantages and disadvantages and are better suited for specific applications. These methods include: injection molding, blow molding, thermoforming, transfer molding, reaction injection molding, compression molding, and extrusion.

Molding service provides high accuracy and consistency - injection moulding manufacturer/ supplier.

Plastics processing through the homogeneous mixing of additives, particularly in extruders at temperatures above the melting point.

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.

Dressler Group (DG) has four brand values: flexibility, quality, innovation – and service. The last point is so important, a Dressler subsidiary bears its name: Dressler Group Customer Service. After all, the family business is renowned for its absolute customer focus. The best way to get to know Dressler Group is in person: Your contacts: Jan Dressler, CEO, COO: jan.dressler@dressler-group.com Christian Manteuffel, Team Manager Sales: manteuffel@dressler-group.com Alexander Leis, Staff Member Sales: leis@dressler-group.com

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.

Fine grinding of dry products is a core competence of the Dressler Group. An extensive range of machine and system programs are available for this, offering the right solution for almost all applications. Finenesses from 1 μm (d97) and into the millimetre range can be reproduced here.

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.

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.

We grind our customers products at temperatures below room temperature.

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!

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.

Large Quantities: produced as cold formed parts (so-called multi-station presses), which require high output volumes in order to achieve a reasonable price parts Small Quantities: Produced as turned parts - the economic adjustment to small batch sizes Fields of application: For thermoplastics, duroplastics, light alloys, metal compounds. Industrial consumers: Electrical industry, plastics processing industry, sheet metal processing industry, telecommunications, tank- and container construction.

FT water temperature controllers make it possible not only to cut down on the use of electrical power for heating (in fact, the heating elements remain off during steady-state operation), but they also make it possible to limit the cooling power spent on cooling by self-stabilizing through a process called Autotuning. This system also saves resources (water and energy) compared to units without them. They are designed to condition molds and cylinders for various industrial processes, including plastics and rubber molding and extrusion, and in the paper industry.

At the moment company operates 54 injection moulding machines, which gives us flexibility to produce different size and purpose plastic parts.

CNC bending of sheet metal technology is the most popular method of plastic processing, allowing to obtain details of both simple and complex shapes. The use of modern press brakes allows for the maximum possible repeatability in cnc bending of the produced elements for any number of items. The modern CNC tube bending services and the automatic compensation of the deflection arrow give maximum accuracy and repeatability in 7 axes and allow you to maintain the required angles along the entire length of the bending line. An extensive tool park allows us to adapt to any customer’s technological requirements. We offer sheet metal bending services, such as tube bending, metal curving, metal sheet folding, aluminum sheet bending, bending steel and many more.

Static Electricity is a major problem that has seriois impact on product quality, throughput and worker safety in many industries. In electronics and media, ESD Electrostatic Discharge affects semiconductor manufacturing, electronics assembly, flat panel display & hard disk drive production, and film processing. In industrial, food, telecom, textile, packaging, chemical, medical and pharmaceutical manufacturing, static electricity creates problems with cling and particulates such as in the processing of paper, fabrics, plastics, powders and other materials.
