This will usually centre around the servicing of primary production equipment, conducted by skilled staff or the OEM service team.<\/strong><\/p>\n<p><!--more--><\/p>\n<p>But what about other \u2018links\u2019 in the production chain?<\/p>\n<p>An example is an injection moulding machine which may have had its hydraulic oil changed and filters replaced. But is its heat exchanger performing efficiently?<\/p>\n<p><em>Hot water is known to release and deposit limescale, which in combination with other contaminants and corrosion can reduce the cooling capacity of a heat exchanger, leading to oil overheating and degradation.\u00a0 <\/em><\/p>\n<p>Limescale build up is, in fact, a major issue in most plastic processing facilities, even more so in known hard water areas.\u00a0 Other common issues include:<\/p>\n<ul>\n<li>Reduced water circulation and heat exchange within production tools and dies<\/li>\n<li>Flow reduction in water hoses<\/li>\n<li>TCU\u2019s (Water Heaters) becoming clogged and pumps burning out<\/li>\n<\/ul>\n<p>The use of additives in the main factory water system can help, but contaminants stay in circulation, there is no equipment \u2018flushing,\u2019 and expensive additives are continually diluted.<\/p>\n<p><strong>The solution to all these issues is the scheduled de-scaling and cleaning of all circuits that carry hot water. <\/strong><\/p>\n<p>Specialised equipment such as the HB Therm Clean-5 unit can clean water circuits without the need for stripping down tools, heat exchangers or TCU\u2019s.<\/p>\n<p>An integrated logbook tracks the cleaning process and provides downloadable data that can be analysed and recorded.<\/p>\n<ul>\n<li>Food grade chemicals dissolve limescale and rust, as well as provide extended protection in storage<\/li>\n<li>A flow reversal system breaks down even major blockages<\/li>\n<li>Multiple rinsing with automated filling and draining removes any released contaminants<\/li>\n<li>Only the required amount of chemical is used for each application<\/li>\n<li>Cleaning chemicals are safely neutralized before being drained from the system<\/li>\n<\/ul>\n<p>Once items such as mould tools have been thoroughly cleaned, shorter cleaning cycles can be scheduled and implemented to maintain levels of cleanliness.<\/p>\n<p>So, what improvements can you expect to see if you implement a scheduled de-scaling and cleaning program?<\/p>\n<p><strong>Improved<\/strong><strong> production levels.\u00a0 <\/strong>Tools and dies with pristine waterways can remove heat evenly and efficiently.\u00a0 For example, an injection moulded part will take less time to cool and will be less likely to distort.<\/p>\n<p><strong>Reduced<\/strong><strong> energy costs.\u00a0 <\/strong>Factory cooling systems are subjected to less \u2018strain\u2019 if tools and heat exchangers are correctly maintained.\u00a0 This is particularly relevant in the warmer summer months.<\/p>\n<p><strong>Reduced<\/strong><strong> maintenance costs.\u00a0 <\/strong>This relates to both labour and repair costs. An example is removing the need to strip equipment and manually \u2018drill-out\u2019 blockages, or by reducing the load on a TCU\u2019s pump.<\/p>\n<p>In conclusion, de-scaling and cleaning equipment can be an effective addition to your preventative maintenance program.<\/p>\n<p>In our own experience, companies that have purchased a Clean-5 unit have seen major benefits and frequently go on to buy additional units.<\/p>\n<p>If you would like more advise on how HB Therm can help to improve your current preventative maintenance program, then please contact Pete Adams on 01925 644100.<\/p>\n<p><em><img decoding=\"async\" class=\"alignnone wp-image-23306\" src=\"https:\/\/www.plastikcity.co.uk\/blog\/wp-content\/uploads\/2019\/05\/kraussmaffei-group-logo.jpg\" alt=\"KraussMaffei Logo\" width=\"231\" height=\"77\" \/><\/em><\/p>\n<p><em>KraussMaffei Group<\/em><br \/>\n<em>+44 (0) 1925 644100\u00a0<\/em><br \/>\n<a href=\"https:\/\/www.kraussmaffei.com\/en\/home\" target=\"_blank\" rel=\"noopener noreferrer\"><em>Website<\/em><\/a><br \/>\n<a href=\"mailto:Jude.Hill@kraussmaffei.co.uk\" target=\"_blank\" rel=\"noopener noreferrer\"><em>Email<\/em><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Most modern plastic processing companies will employ a preventative maintenance program.
