resin based moulds for first prototypes with the original material

In Fused Deposition Modelling (FDM), thermoplastic material is applied layer by layer and built up precisely according to digital CAD data. This tried-and-tested additive manufacturing process is particularly suitable for functional technical components and large-scale structures. Thanks to our large-format 3D printing systems, we can produce components, enabling even extensive and complex geometries to be efficiently realised without tooling costs. This makes large-format 3D printing particularly attractive for companies that require rapid iteration cycles or wish to produce small batches cost-effectively. Depending on the application, we process a wide range of thermoplastics. Particularly for high-stress industrial applications, we rely on engineering 3D printing materials.

Hier die englische Version (ca. 1.400 Zeichen): Plastic Welding System A2A® – GEFASOFT A2A® (Absorbent to Absorbent) is a patented laser welding technology developed by GEFASOFT that joins two laser-absorbing components directly – without the need for a transparent joining partner. Compared to conventional transmission laser welding, A2A® offers significantly greater design freedom and opens up new application possibilities. Key Benefits: High flexibility thanks to simple tooling and fast changeover between component variants Low production costs compared to dispensing or screwing processes Clean, particle-free process – ideal for sensitive applications Precise, targeted energy input exclusively in the weld zone High process control through integrable vision/image processing systems Low maintenance effort and easy integration into existing production lines Working Principle: The joining partners are positioned with precise alignment, the joint surfaces are evenly heated using laser energy, precisely aligned to one another, and joined together under defined pressure. During the cooling phase, the parts are held in place, resulting in a homogeneous, dense, and materially bonded weld seam – combined with high process reliability and flexibility in component design. Typical Applications: Complex plastic housings with high design and sealing requirements Components with limited accessibility or geometric shadowing Pre-assembled units with sensitive internal components Medical technology requiring high levels of cleanliness and particle-free processing Automotive and industrial components with high demands on process stability Components with varying materials or increased tolerances With A2A®, companies invest in a future-proof technology that sustainably improves efficiency, process stability, and versatility in plastic welding.

The Deltaplus Masterbatches product range offers new property profiles. As concentrates, they contribute sliding properties, make materials permanently antistatic, improve impact strength or modify weight and density, among other things. We can also offer products with flame-retardant properties

The Aero2 PCS® ULTRA ULTRA Versatile Dry Ice Blaster. The Aero2 PCS ULTRA is the most versatile dry ice blasting machine on the market. Equipped with our patented particle control system (PCS®), this machine offers operators complete control of the particle size being blasted to fine-tune their blasting parameters for each unique application. From 0.3mm to 3.0mm, and every tenth of a millimeter between, this machine allows operators to select from 1 of 28 particle sizes to dial in their blasting parameters for optimal performance. Blasting a delicate surface? Select a smaller particle size, say 0.4mm, and blast at a lower pressure. Looking to remove stubborn contaminant? Select a larger particle size, say 2.8mm, and blast at a higher pressure. With a 7” LCD screen and digital controls, the PCS ULTRA provides an intuitive display that allows the user to easily view and adjust blasting parameters and machine settings. The machine also features programmable application recipes, which allows users to set and save blasting parameters, such as blast pressure, particle size and feed rate. Lastly, the PCS ULTRA introduces our patent-pending defrost cycle for moisture control, core cleaning, and increased machine uptime. The PCS ULTRA is IoT enabled via Cold Jet’s Industry 4.0 solution, Cold Jet CONNECT®. The system provides remote monitoring and diagnostics, training videos, machine documentation, and self-guided troubleshooting at your fingertips. Should more assistance be required, operators can quickly and easily connect with Cold Jet service technicians via chat, service tickets or voice and video call.

If you want to remove components from the injection moulding machine and cut off sprues or cut metal wires, you need powerful air nippers.

We are the contact for the development, pilot-scale production and further processing of UD tapes as well as their evaluation.

Artificial weathering is used to accelerate the replication of natural solar and environmental influences. Materials are exposed to precisely defined light and climatic conditions in order to simulate photochemical ageing processes under laboratory conditions. This allows changes such as loss of colour and gloss, embrittlement or cracking to be assessed at an early stage, enabling a reliable evaluation of long-term durability. We offer testing acc. to, among others, the following standards: - Xenon weathering acc. to DIN EN ISO 4892-2 - Colour fastness and aging acc. to DIN EN ISO 105 B06 - Colour fastness acc. to VDA 75202 - Weathering acc. to MBN 55555-5 - Kalahari and Florida tests acc. to VW PV 3929 and PV 3930 - Exposure testing for automotive interior parts acc. to VW PV 1303 - Solar simulation acc. to DIN 75220 and DIN EN IEC 60068-2-5 The tests provide reliable information on long-term durability, material stability, and operational reliability under real-world environmental conditions.
