Established in the UK in 1988 as the sole agent for Gunther Heisskanaltechnik GmbH, at Gunther UK we have established ourselves as one of the leading hot runner suppliers in the UK and Ireland. A product that is at the top end of the market and a dedication to UK based service back-up has given us an enviable reputation in all market sectors of the injection moulding industry – medical, automotive, packaging, household and electrical to name just a few. Since those early beginnings we have developed our product portfolio, introducing high quality manufacturers into the UK to try and give you, the customer, one place where you can get almost all your tooling needs – a one stop shop.

The Gunther Hot runner System has an innovative and patented bi-metallic titanium shaft at the core of it’s technical advantages over other systems which minimises heat transfer from hot runner nozzle to mould tool but which additionally gives a perfect seal in the tool. Both open and valve gate systems are available for single  or high cavity production moulds as systems only or as completed hot halves. Other innovations include the new ‘Blueflow®’ heater technology (www.blueflow.de) giving a slimmer and more energy efficient hot runner nozzle, special PM inserts for valve gate systems and we were also the first system to offer a plate operated valve gate system, a market sector we remain at the forefront of. Advanced designs of multi tip nozzle and a full selection of hot runner controllers complement the range and we are happy to give you the right advice over which system/design is suitable for you application. Installation and mould trial attendance/assistance are also available via the UK. For the full range and for more information either contact us directly in the UK or you can visit the main Gunther website www.guenther-heisskanal.de


To further complement our range we also introduced a specialist range of mould accessories from Rainer Knarr GmbH in 2011. With a large range of industry-standard size ejector pins, pillars, bushes, sleeves and other parts Rainer Knarr also specialise in DLC and Cr2N coated parts which are ideal for the medical and food packaging industries as they require no lubricants. Two particular innovations that are also available are patented stepless ejector sleeves and also blade ejectors with 2 or 4 corner radii.

We can manufacture special parts at competitive prices with short lead times and no minimum quantity. Please call for a catalogue or sales visit or you can visit our web site at www.rainer-knarr.de


The most recent addition to our range has been the company Ferrofacta GmbH. Whilst we do not currently offer standard P plates we are happy to now offer specially machined plates, to your models from different sources worldwide but still with the comfort of dealing with a quality German company. Available in your specified tool steel these plates can be supplied to tight tolerances with all bores, threads, chamfers etc machined.

The website address is www.ferrofacta.de or of course you can contact us in the UK directly.


In 2009 we also introduced the name of mould cooling specialist, Contura  GmbH into the UK and Ireland. The importance of mould cooling can sometimes be overlooked at the design stage leading to long cycle times or poor plastic parts but, using a range of different bonding techniques Contura can offer a conformal cooling system allowing you to place your water close to the part to have the maximum influence.

It is not uncommon to see a cycle time saving of up to 50% with an average saving of 30%. With these types of savings the costs can be usually be recouped in a matter of months but the benefits can be seen for years. To see how conformal cooling can help you save time and money please visit www.contura-mtc.de or call us in the UK.
