Material Solutions by CERATIZIT delivers both The hot runner nozzles are of decisive nozzle tips for hot runner nozzles as well as importance in this process as the critical shut-off needles. interface between the cavity and the machine, since they represent the plastification unit. Process efficiency with all materials Carbide nozzles ensure good transport, master Whether you process thermoplastics, elastomer the transmission superbly while also ensuring or thermosetting plastics, metals or ceramics excellent thermal stability. (MIM, CIM) or whatever – solutions from CERATIZIT always ensure a homogeneous For all systems and stable injection moulding process. Valve gate nozzles allow carbide to show its This is particularly important for sophisticated strengths: excellent heat conductivity, maximum components which have to be produced in high wear protection with abrasive plastics and quantities. In this case hot runner systems are abrasion of the shut-off needle. We supply almost always used. components for all hot runner systems, whether open or valve gate systems. In the first case Ideal nozzles there are different types of nozzle tips, with Such a system connects the entrance of the one or more openings. plastification unit with the mould of the injection moulding tool (the cavity) and is thermally Advantages Benefits Optimised carbide grades Very good heat transmission, optimal Very high thermal conductivity, high wear flow properties in the hot runner nozzles, resistance and corrosion resistance with homogeneous final products, maximum working temperatures even over 400°C tool life, highest process reliability Versatile production Individual geometries can be provided at any Almost every execution can be made to time, innovation can always be looked into customer’s request, highly precise manufacture for minimum tolerances Manufacturer’s expertise Innovative partner on your level, on site Advice for every application from our sales presence in next to no time representatives and product manager staff, detailed technical expertise in dealing with materials, processes and products www.ceratizit.com HARD MATERIAL SOLUTIONS BY CERATIZIT PLASTICS INDUSTRY 2019 7 Product overview Nozzle tips Standard types Individual solutions ▲ Ready-to-use products: finish-ground nozzle ▲ Design according to customer drawing tips with a surface quality up to Ra 0.02 µm, ▲ For any type of assembly situation (e.g. polished, for open systems (hole as sintered) specific threads and forms of the outer and shut-off needle systems (ground exit profile) hole) ▲ Complicated hole geometries for special ▲ Semi-finished products: as sintered nozzles components with preground areas, exactly ▲ Nozzle tips are available as hybrid and tailored to your needs and the possibilities composite parts.
