  • New coating solves a sticky problem for Norprint
    s largest independent labelling companies with a capacity of 6 7 billion tickets tags and labels every year The company operates thirty presses including digital rotary flexo letterpress and custom designed machines Several of the label presses operate a re lam and de lam process that peels the backing paper from a self adhesive stock allowing the machine to print onto the adhesive It then joins the two substrates together again The stock can stick to the rollers when the machine is running and in order to minimise the problem Norprint had been covering the rollers with a layer of silicone paper The search for a solution took us to the Internet where we found the Poeton website explains Norprint production manager Malcolm Keightley We then phoned Poeton and discussed the problem with coating specialist Trevor Amos who recommended Apticote 810SP a coating that has been specially designed for print and packaging applications involving adhesives Poeton has been very helpful and the whole process has been easily managed by email telephone and post Initial indications at Norprint show that Apticote 810SP is helping to increase production and reduce costs and material wastage It is expected that Apticote 810SP will be used on six machines possibly more with other rollers due to be sent for coating Says Trevor Amos Following the original contact they sent us one roller for coating which we returned for testing The self adhesive stock ran without sticking and there was no drag from the material They were so impressed with the results after a one month trial that they sent another six rollers for coating which are now fitted and operational on three presses 20 April 2010 Back to Success Stories List Aerospace Defence Medical Healthcare Energy Power Generation Automotive Chemical Oil and Gas Food Drink

  • Apticote, the case for Mould Release Coatings
    aluminium There are also many different types of materials which means that curing and setting temperatures vary widely in the case of plastics and rubber these can vary from 140 c to 340 c It is also far cheaper to coat a new mould than to try to clean a contaminated production tool And of course there are many different types of moulding Here s a brief overview Flow Moulding Commonly used for plastic pipes plastic sheet rubber tube etc forces material through a set of dies in semi liquid condition as a continuous stream The material is then set using water to produce the end product Spin Moulding Used where flow moulding cannot produce the shape Very dense and durable materials can be used to produce products such as toilet seats some children s toys etc Blow Moulding Used for high volume applications for example to produce containers such as bottles for milk soft drinks etc Compression Moulding Applies high pressure to powders such as polyethylene or synthetic rubbers which are then heat cured for items such as tyre moulds Vacuum Moulding Used to produce a wide variety of products from baths and sinks to margarine and yoghurt tubs by sucking an already partially cured sheet of material into a mould form Injection Moulding Feeds material in pellet form into a hopper where it is heated to flow conditions and forced into a mould The fact that each method of moulding will require a different release agent is further complicated by the many different types of materials used to manufacture moulds Here are some examples of materials applications and the type of coating that should be specified Rubbers Rubber comes in many forms nowadays all synthetic The aluminium segmental moulds used to produce tyres will require different coatings for different rubbers For standard silicon rubber an anodic composite coating such as Apticote 350 will be ideal whereas carbon black rubber will require a nickel alloy or nickel composite coating such as Apticote 450 460G or 200A Applied correctly they will last for years Steel moulds will accept Apticote 400 and 450 but not Apticote 350 which is designed for light alloys The steel moulds used to produce Viton and Neoprene seals will need a coating such as Apticote 460G Its combination of hardness and lubricity is designed to produce the best results and long life for high volume applications And the steels moulds used for very abrasive memory rubbers will need a nickel composite such as Apticote 450 a unique nickel alloy composite designed for even lower friction and greater load carrying capacity However depending on the application speed and volume even using this coating moulds could need re coating every 3 months Coatings such as Apticote 200 350 450 and 460 which are already used extensively for tyre moulding applications have excellent release properties and are extremely resistant to the high temperatures and aggressive materials used in tyre manufacture For the production of larger tyres where sidewall plates

  • Poeton coating gives 50-year life in corrosive environments
    Poeton coating gives 50 year life in corrosive environments A special anti corrosive surface treatment one that was developed by Poeton Industries to coat storage drums containing low risk contaminated waste is now available for industrial and defence applications where long term exposure to aggressive environments is a problem The Apticote treatment consists of a sacrificial super zinc base coating with a spray applied two pack epoxy polymer finish Poeton R D manager John Archer says the coating was originally designed to provide a 50 year life for more than 5 000 BNFL storage drums which were constructed of mild steel with inner and outer containers and a lid All surfaces were completely coated to resist any form of corrosive attack Explaining the long service life he says corrosion can easily attack a conventional envelope coating such as paint through minute holes in its surface while a sacrificial coatings such as zinc galvanising relies on progressive oxidation to protect the surface The reason the Apticote treatment is so durable is that it protects the sacrificial coating with an extremely tough corrosion resistant epoxy polymer one that has already lasted ten years in our own atmospheric tests with absolutely no signs of deterioration Poeton now offer the same coating to prevent saltwater or atmospheric corrosion of components or structures in marine defence and industrial applications For enquiries please contact Trevor Amos the Poeton Group Sales Manager through the help line box 18 April 2010 Back to Success Stories List Aerospace Defence Medical Healthcare Energy Power Generation Automotive Chemical Oil and Gas Food Drink Equipment Electronics Telecoms General Engineering GLOBAL SUPPORT Poeton Apticote supporting global manufacturing from A to Z Design Support Research Development Test Samples First Articles Pre Production Full Rate Production COATINGS FROM POETON Core Standard Coatings APTICOTE 100 Hard

  • New filtration systems eliminates pitting from hard chrome plating
    chrome plating it produces by introducing a more efficient and environmentally friendly high pressure filtration system into its processing plant Group R D Manager Dr John Archer claims that the company s new Apticote 100 process which costs no more than conventional hard chrome plating eliminates the problems of pitting that can seriously affect critical components such as aircraft undercarriages hydraulic actuators bearings etc The innovative filtration system uses special high pressure pumps made from titanium to agitate the plating solution more efficiently and force it through a series of novel circulation enhancing valves and filters which remove even the finest particles that are the main cause of quality problems in hard chrome plating More efficient filtration also makes a significant environmental contribution by minimising effluent which extends the life of the solution and reduces the environmental impact of chrome plating The system also improves solution conductivity which saves energy and increases processing speed A reduction in the fume emissions caused by air bubbles bursting on the surface of the solution a common problem associated with the more expensive and less efficient compressed air method of filtration provides further environmental improvements Explaining the significance of the new process John Archer says that visually all chrome looks the same so the efficiency of the new Apticote 100 process allows customers with critical applications to specify hard chrome plating with confidence Eliminating the pitting that is present on the surface of conventional hard chrome plating coupled with the increased plating speed make this new plant very cost effective providing significant benefits for customers he says adding that faster plating with improved pitting reductions at less cost makes the new Apticote 100 Chrome a double winner 17 April 2010 Back to Success Stories List Aerospace Defence Medical Healthcare Energy Power Generation Automotive Chemical

  • Surface Coating - The clean and cost effective alternative to messy, wasteful spray release agents
    25 000 The South Wales based Coopers Division of Sogefi Filtration manufactures air oil and fuel filters for cars and heavy goods vehicles To produce an after market air filter for a leading car range the company was using 150 sets of ferritic stainless steel moulds supplied by a sister company Prior to production the moulds were coated with a PVC chemical incorporating a release agent which then had to be oven cured Despite the coating the presence of carbon in the stainless steel caused the moulds to corrode making it impossible to remove filters without ripping their seals A zinc coating applied by a local company also failed to prevent sticking and even getting coatings to stick to the moulds was proving to be a problem It was at this point with the company facing a 25 000 bill to replace the moulds that the engineering department called in Poeton Says Sogefi s Gwyn Thomas By this time the moulds were in poor state and very badly rusted and the profile meant they would be difficult to clean or polish In spite of their condition Poeton was able to apply a number of its Apticote coatings for us to test for compatibility Apticote 460G one of a family of nickel polymer coatings developed for rubber and polymer moulding applications produced the best result Its combination of permanent lubricity and high hardness enabled filters to be easily released and significantly extended the life of the moulds Gwyn reports that eighteen months later with an estimated 60 000 filters produced there are no signs of wear or deterioration in the coating even though a metal gauze inside the filters rubs against its surface during the process 15 April 2010 Back to Success Stories List Aerospace Defence Medical Healthcare Energy Power Generation

  • Surface Coating - The clean and cost effective alternative to messy, wasteful spray release agents
    many cleaning operations are eradicated Another can operate at extremes of temperature from 200 C to 285 C and is chemical resistant and FDA compliant Advanced Apticote hard anodic composites combine excellent low friction and release properties to offer a unique approach to precision hard anodising providing a completely uniform surface layer of predictable thickness As surface growth is 50 of the total coating thickness final dimensions can be accurately predicted to eliminate the need for costly mould finishing operations An electroless nickel composite offers the opportunity to substantially reduce material costs by coating low cost materials to meet the needs of high performance moulding applications For example moulds manufactured from low carbon steel and coated with this Apticote coating can be used to replace more expensive alloy moulds with no loss of performance And costs are further reduced because moulds can be machined from more workable and readily available metals And a special coating has been developed for rubber and polymer moulding applications that require permanent mould release properties It is designed to provide excellent mould release where maximum chemical and abrasion resistance is required USDA and FDA compliant Apticote coatings are ideal for food and drink cosmetic and pharmaceutical applications They have achieved four times the wear resistance of electroless nickel in Tabor Abrasor Tests outperform hard chrome in dry running applications and will operate at temperatures from 115 C to 260 C Using a specialised coating Poeton helped solve a sticky packaging problem for Rexam one of the world s top ten consumer packaging suppliers and a leading European supplier of thin wall plastic containers for the food industry At its factory in Yate near Bristol in the UK Rexam has developed a proprietary process to mould high volume trays using PET an advanced packaging material that is specified by major food brands because its clear finish allows consumers to see the product inside the pack However whilst PET has obvious advantages for Rexam customers it can be difficult to process in high volume moulding machines being both abrasive and sticky Its abrasive properties cause aluminium moulds to wear quickly and its stickiness makes it difficult to remove trays from moulds problems that have a seriously affect on high volume production Also because trays stick together when stacked de nesting is also difficult and slows down the customer s production lines Both problems were experienced recently at Rexam on a line producing trays for a major food product line To overcome the de nesting problem Rexam had been grit blasting the mould to roughen the surface and blending an expensive migrating wax additive with the PET Whilst this approach improved de nesting it didn t solve the mould wear problem and as the additive left a residue the mould also needed regular cleaning At this stage the issue of pack clarity became secondary to the high volume needs of the customer and Paul Hawkins technical manager at the Yate site called in Poeton to advise on coatings
