\nEven though elm-plastic\u2019s product range mainly comprises pharmaceutical primary packaging materials and dosage aids for human and veterinary preparations, the company repeatedly works on projects from different areas. These include a product with a highly demanding geometry that is to be sold in DIY stores in future. The HDPE injection moulding is produced on an 8-cavity mould. \u201cThe customer calls off batch sizes of 400,000 articles several times a year,\u201d explains Roman M\u00f6hs, development manager at elm-plastic. The geometry of the article posed a particular challenge, however. \u201cOur 500 kN injection moulding machine is actually ideally suited to this article with its 8-cavity production,\u201d explains M\u00f6hs, \u201cbut the permitted installation height is somewhat tight for the application. We had to find a different solution, because switching to the next largest 750 kN machine was not a re

The demanding gate for the relatively small, complex article prompted HASCO to additionally conduct a Moldex filling simulation, or flow analysis \u2013 a service that HASCO generally offers its customers free of charge. This simulation resulted in the gating point being moved by a number of millimetres prior to the manufacture of the mould so as to avoid air inclusions.<\/p>\n M\u00f6hs was pleased that the delivery time for the individually designed and manufactured 8-cavity Streamrunner with its modified screw-in 20 mm Techni Shot nozzles was only slightly longer. \u201cWe can easily recover the slightly higher costs by\u00a0 The mould has moving parts on the ejector side. The DLC (Diamond-Like Carbon) coating on the slideways reduces the coefficients of friction and permits a considerably longer mould life without separate lubrication.<\/p>\n Bild 5\u00a0<\/strong><\/p>\n Faring well in the crisis with medical devices<\/strong> \u201cOur product range primarily comprises pharmaceutical packaging materials and dosage aids for human and veterinary preparations. Apart from disposable syringes, this also includes products such as pipettes, applicators and injectors in a wide range of designs, dosage aids, perforated screw caps, pipette wipers and a great deal more,\u201d explains M\u00f6hs.<\/p>\n During the corona crisis, additional orders have been received, even from the USA, for items including measuring beakers and a wide variety of pipettes.<\/p>\n The positive experience obtained with these projects is the reason for elm-plastic \u201cto continue working together closely with HASCO\u201d says M\u00f6hs.<\/p>\n For elm-plastic, is it a huge advantage that all HASCO\u2019s standard components can be supplied from stock and that replacements are available without any problems in the event of a failure. \u201cIf we order a replacement part in the online shop, it\u2019s there within 24 hours\u201d. We can\u2019t even produce a replacement part ourselves that quickly,\u201d adds M\u00f6hs. And the restructured hot runner zone in the HASCO online portal has also had a large amount of information added to it. One feature is the new, intuitive enquiry form, which can be used to request hot runner systems in a straightforward and time-saving manner.

\nThe in-house mouldmaking department at elm-plastic, which produces some five to ten moulds itself each year, relies on standard components and hot runner technology from HASCO. Roman M\u00f6hs looks back to the last K \u2013 the world\u2019s leading trade fair for the plastics and rubber industry in D\u00fcsseldorf \u2013 where the HASCO specialists presented a new development. \u201cThe new Streamrunner has indeed made it possible to save 10 mm on the mould thickness for this project, despite the complex installation situation and the demanding gating,\u201d explains Stephan Hatarik, a technical sales engineer at HASCO hot runner. Since the manifold block, which is available on the market exclusively from HASCO, is manufactured in an additive laser sintering process, the complete \u201chot half\u201d can be produced much more compactly. \u201cThis gives us the necessary space for the opening stroke to ensure reliable demoulding,\u201d says M\u00f6hs, \u201cand we also have a certain reserve when it comes to the installation height and ejector stroke, etc.\u201d This would have been almost impossible with a conventional standard hot runner, the development manager stresses. \u201cAnd 10 mm is really a lot for a cylindrical article with a length of 25 mm,\u201d he adds. A further key advantage of the 3D-printed manifold is that the flow channels can be freely designed to suit the precise requirements, thus ensuring an optimally balanced design with radii everywhere and hence, no dead corners. The additive manufacture of the hot runner employing the 3D laser sintering process enables the complete manifold block, including all the threads, to be manufactured in one piece in a single operation. \u201cNo deflection elements have to be shrunk in, which could then leak,\u201d Hatarik explains. In addition, 3D printing permits very close hole spacing and highly variable nozzle configurations.<\/p>\n<\/p>\n<\/a>using\u00a0the smaller machine.\u201d He was delighted about the HASCO innovations, which enabled the entire project to be carried out and handled without any problems. The fact that the nozzle tips and the heating can be installed from the parting plane also proved to be a great help, since this facilitates maintenance.<\/p>\n<\/a>Even though the current project is an article\u00a0for DIY stores, the absence of lubrication is important for elm-plastic because the machines\u00a0are operated primarily in a clean-room environment for the production of medical devices. All the injection moulding machines at elm-plastics have all-electric drives.<\/p>\n
\nSince elm-plastic produces mainly products for eminent international pharmacists and contract fillers working for the pharmaceutical industry, the Eifel-based company has not suffered any significant loss of sales during the corona crisis.<\/p>\n<\/a><\/p>\n
\nWith more than 100,000 products, HASCO is a full-range supplier for tool and mouldmaking and supplies its customers with everything from a single source. A modular standard-component range, perfectly tailored to customer requirements, and individual hot runner solutions provide a reliable basis for high-quality moulds and hence, sustainable competitiveness.<\/p>\n","protected":false},"excerpt":{"rendered":"
