Everything you need to know about UV system reflectors

Posted by admin on February 5, 2019

Alpha-Cure has over 22 years’ experience in the manufacture of UV curing lamps and we certainly know our way around a UV curing system. We help our customers find the right replacement UV reflectors for their system every day, so we have plenty of experience in finding the right solution for the problem. In this blog we aim to share our knowledge with you so that you are able to extend the useful lifetime of your reflectors and ensure a high-quality cure every time.

What are UV system reflectors?

An integral element of many UV systems are the reflectors which, as the name would suggest, help to reflect UV light onto the substrate. Up to 70% of the UV energy that reaches the substrate comes from the reflectors, so they are critical in ensuring the UV system is operating effectively.

Why are there different types of UV reflectors?

UV system reflectors are available in a range of materials and geometric shapes to suit different the range of UV curing applications. Materials include:

  • Highly polished aluminium: These are commonly used for focusing ultraviolet light from a medium pressure mercury vapour lamp, UV curing lamp or metal halide lamp as metal halide reflectors.

  • Dichroic coated aluminium: These reflect visible light and allow infrared radiation to pass through. This type reduces heating of illuminated objects since less infrared radiation is present in the light beam.

  • UV coated quartz: Quartz material is stronger than glass and therefore can be used at temperatures up to 1050 ° C and has a high transmission from 230nm to 3000nm. This makes it useful for most UV applications.

Alpha-Cure can also supply extruded reflectors, stainless steel reflectors, bora silica and many more.

How do I look after my reflectors?

We recommend our customers check and carefully clean their system reflectors every time they change the UV lamps, and they should expect to have to replace reflectors every 3 or 4 lamp changes. If a reflector appears deformed or distorted, and cleaning it makes no difference, we would advise it is replaced as soon as possible no matter how old it is.

Material matters – what goes into an Alpha-Cure UV lamp?

Posted by admin on December 18, 2018

Alpha-Cure has spent over 22 years developing expertise in UV lamp manufacturing, and we’re proud to say that we use only the highest quality materials to produce our market-leading products. Every single one of our medium-pressure UV lamps are individually hand-made by our skilled staff to ensure a final product that our customers can rely on and UV system manufacturers can trust to deliver in their equipment.

At Alpha-Cure we use:

  • The highest-grade vacuum-baked quartz
  • Ultra-high purity noble gases
  • Mercury purity reaching levels of 99.995%
  • Aviation grade lead terminations

Here’s some more information about the materials used to create our lamps and the properties they have been chosen for:

High-grade fused quartz

Alpha-Cure uses the highest-grade purity quartz available on the market. Fused quartz has a high thermal stability and melting point (1665°C – glass melts at 600°C). The UV transmission of quartz is excellent, providing up to 95% UV transparency. The thickness of the quartz has been carefully chosen – ideally it must be thick to ensure maximum UV transmission, but it must also be sufficiently thick for thermal stability and to prevent the lamp body bowing.

Tungsten electrodes

Tungsten has the highest melting point of any metal and this coupled with its excellent thermal conductivity and stability makes it ideal for use in electrodes. The tungsten electrodes are connected to the molybdenum foil seals with platinum.

Molybdenum foil seals

Molybdenum is used in the seals of our lamps as it has a very similar coefficient of thermal expansion to the quartz we used – this means that both materials will fluctuate in size the same amount as they heat and cool, preventing cracking of the seal. It is also a good electrical conductor and has high resistance to corrosion.

Ceramic cap and cement

Ceramic has high dielectric strength, meaning that it can withstand a relatively high voltage before ‘dielectric breakdown’ occurs. Dielectric breakdown means that that current flows through an electrical insulator when the voltage applied across it exceeds the breakdown voltage.

UV curing in automotive manufacturing

Posted by admin on November 13, 2018


The applications of UV curing are incredibly widespread – in fact, the likelihood is that right now you are either using, sitting on, wearing or very near something that required UV curing during its manufacturing process.

Alpha-Cure is the world’s leading manufacturer of medium-pressure UV curing lamps which are used around the world in a range of industries to cure inks, coatings, varnishes, lacquers, resins and glues. A huge number of those lamps are supplied to OEMs and end users in the commercial printing sector for use in UV systems on digital, offset, flexo, litho, screen and letterpress printing presses.

Our lamps are also used in automotive manufacturing, and for this blog we’re taking a look at some of the elements of your car which have been created with the help of medium pressure UV curing lamps.


UV coating has been used in the manufacture of headlamps for over 30 years, being in both the main components of the part – the polycarbonate lens and the reflector housing. The lens needs a tough, scratch-resistant coating to protect the polycarbonate, and UV coatings provide this with an instant cure time to save money. The reflector housing is protected and sealed with UV coating.

Alloy wheels

UV curable coating can be applied to alloy wheels to protect the finish from the effects of water, ice, salt, grit and accidental scratched and light damage. The coating will be cured instantly once exposed to UV light emitted by a medium pressure lamp, ensuring quicker drying times than air or heat dried coatings.

Body panels

Another use of UV coating in automotive manufacture is the application of a UV cured clear coating on molded body panels. The benefits of a UV coating are that it is tough and durable whilst retaining flexibility, and it can be readily used on plastic panels as there is no heat involved to cure the coating, which would otherwise distort the shape. The UV coating means that it won’t crack when it is hit by objects kicked up by the tyres or other vehicles. As with all UV coatings it is a quick process, meaning production lines can move rapidly and there is no requirement for drying space.

Alpha-Cure lamps are manufactured from high quality materials by our experienced staff to ensure guaranteed curing performance and long working lifetime. Take a look at our product range here.


7 steps to a complete UV lamp and system maintenance schedule

Posted by admin on October 23, 2018


Alpha-Cure has over 22 years’ experience in UV lamp manufacturing and curing processes, and we know how to manufacture UV lamps that deliver impressive curing results for well beyond our warranted hours. Alpha-Cure lamps are used by leading OEMs and busy end users around the world for print curing on a wide range of substrates, wood and wood laminate product manufacture, automotive manufacture, PCB manufacturing and more.

Whatever the application of your UV lamps, it is in your interests to ensure that your lamps are functioning as they should and keep doing so for as long as possible. In this blog we’ve gathered 7 key steps to implement as part of a cleaning and maintenance schedule for your UV lamps and reflectors, to ensure that your system keeps delivering exceptional curing results.

  1. Ensure your UV system is free from dust, paper, ink and any other external contamination.
  2. Clean the lamp/lamps, UV system and reflectors every 500 hours to maintain the longest possible lamp life.
  3. Clean new lamps before they are placed into the system with isopropyl alcohol wipes, ensuring that you wear gloves at all times when handling UV lamps.
  4. Rotate long lamps 180 degrees every 100-200 hours to prevent deformation of the lamp body – do not handle lamps when they are hot, leave them to cool for at least 5 minutes after switching off the UV system.
  5. Avoid excessive starts – this can cause contamination of the lamp due to the electrodes throwing off tungsten into the lamp.
  6. Check reflectors periodically, to make sure they are not scratched, dented and are free from contaminants that will not clean off. Replace reflectors every 4 lamp cycles.

Check the UV lamps in the system are not showing any external signs that could cause poor curing performance. For more information on UV lamp troubleshooting, click here.

UV coatings and varnishes for wooden furniture and flooring

Posted by admin on October 1, 2018

Wooden furniture and floors are treated with varnishes and coatings to ensure the wood is preserved and sealed for years to come, and the finished product’s appearance is of a high quality. Varnishes and coatings are applied layer by layer during the manufacturing process, so ensuring a quick, energy efficient and consistent coating is key.

UV curable stains, primers, sealants and topcoats are all available which have the following benefits for wood furniture and flooring manufacturers:

Shorter production time – the coating takes just a few seconds to cure whereas coatings that require air or IR drying can take several days to totally set. This means in a production line the materials that have been treated can be packed or taken to the next stage of production without having to wait for the coating to dry.

Space saving – eliminating the need for drying times means that less space is needed, as materials can be packed, racked and stored as soon as they come off the production line.

High quality finish – UV coatings give a good gloss and a very hard wearing finish that is resistant to abrasion and scratching and is largely stain and chemical resistant.

Alpha-Cure manufactures market-leading medium pressure UV curing lamps used to cure a full range of sealants and topcoats used in the manufacture of wood furniture and flooring. To find out which UV curing lamp is right for your business please contact the Alpha-Cure sales team who can help you identify the correct lamp for your UV curing system.

Alpha-Cure has over 22 years of experience working with UV curing system manufacturers around the world to develop proprietary lamps for exceptional curing results. Just drop us a line to find out more.

What do you know about infrared (IR) curing lamps?

Posted by admin on July 24, 2018


How does infrared work?
Infrared (IR) energy is a form of radiation, which falls between visible light and microwaves in the electromagnetic spectrum. Infrared lamps use low amounts of energy and work by emitting infrared radiations which can be used for many processes. Infrared heaters produce heat that is a product of invisible light from IR lamps.

What are infrared lamps used for? 
Alpha-Cure supply infrared lamps for many different applications and industrial processes, as well as for the more commonly seen heating of indoor and outdoor spaces in domestic and commercial premises.
Applications of IR include:

• Curing and bonding
• Plastic welding
• Annealing
• PET manufacturing
• Print drying
• Domestic/commercial heating

In these applications, infrared heaters may replace convection ovens and contact heating, UV curing or electrical or gas heating systems. In the case of print drying, infrared may be more suitable than UV curing for some inks and substrates. IR heating is increasingly popular for use in warehouse heating, as it can be targeted directly towards where staff are working, preventing energy being wasted on heating air or building structures.

Find out more about infrared lamps from Alpha-Cure 

Alpha-Cure has a dedicated sales and technical team to assist you, no matter what your IR lamp requirements may be. We have offices in the UK, France, Germany, China and Australia, as well as a global network of official distributors – get in touch with us today!

5 things you can do to help your UV curing lamps last beyond their warranted hours

Posted by admin on May 18, 2018

Alpha-Cure have always been associated with quality and reliability, producing tens of thousands of UV curing lamps every year for our customers. Our UV lamps generally have a warranted life of 1,000 hours, but this can easily be extended provided the lamp is run in accordance with our guidelines and conditions. In fact, Alpha-Cure regularly hears from customers who report that their lamps are still curing at 4,000 hours, thanks to the environment they are operated in and adherence to a stringent cleaning and maintenance programme.

Alpha-Cure’s UV technicians support customers and distributors around the world with troubleshooting and technical advice, and here they share their best practice for handling, cleaning and replacing UV lamps

  • Always wear latex gloves when unpacking and then handling a UV lamp, as any residue and oil from your fingertips will contaminate the surface of the lamp and cause issues once it is ignited.
  • Before placing the lamp into the UV system, ensure you clean the lamp body with isopropanol wipes – these are available from Alpha-Cure’s sales team.
  • For longer lamps, rotate them every 100-200 hours to avoid deformation of the quartz and ‘bowing’.
  • Avoid excessive starts – this can cause contamination due to the electrodes throwing off tungsten into the lamp. When you remove the UV lamp from the system, check that the electrical connections are tight and not eroded.
  • Ensure the UV system is clear of all external contamination, such as inks and paper dust, and clean the lamps regularly with isopropyl wipes. Allow the lamp to cool for at least 5 minutes after the power has been turned off, before you handle the lamp.

Alpha-Cure has over 22 years of experience in UV technology and are experts in troubleshooting issues with lamp and UV system performance. However, even the very best products crafted from the best materials will need to be replaced in the end. Alpha-Cure can provide replacement UV lamps for virtually any UV system, as well as system spares and accessories including:

  • UV system reflectors
  • Quartz plates
  • UV lamp cleaning kits
  • Mercury spill kits
  • UV testing and monitoring products.
  • Chokes, ballasts and ignitors

Contact Alpha-Cure’s technical sales team on 01327 263900 or email sales@alpha-cure.com to discuss your requirements.

From polluted rivers to high-tech water recycling in just 50 years – Singapore water redefined

Posted by admin on May 2, 2018


The remarkable 50-year transformation

The 5.6 million residents of Singapore enjoy a constant supply of clean drinking water that is among the safest in the world. This is a remarkable feat for one of the most densely populated countries in the world that has no native supply of freshwater, and 50 years ago had an open sewer system.

The fact that 100% of the population of Singapore are served by modern sanitation is a result of intensive investment in water treatment technology and infrastructure by the Singapore government. Water used by Singaporeans comes from four “taps” – imported water from neighbouring Malaysia, rainwater that is collected from two thirds of the land and stored in reservoirs, desalination plants processing seawater, and reclaimed (recycled) water.

Reclaimed water is a key part of Singapore’s future

Reclaimed water is seen as critical to the future of Singapore, as it offers the government complete control over an area of their water supply. The other 3 ‘taps’ are subject to fluctuation in cost and subject to availability issues – price rises from the Malaysian government (and an agreement ending in 2061), the high cost of desalination, and the risk of lower than usual rainfall affecting reservoir levels.

NEWater, introduced in 2003, is the name for used water from the sewerage system, treated and further purified through microfiltration, reverse osmosis and ultraviolet disinfection. This reclaimed water is potable, but the majority is used in industrial processes and manufacturing. The Singapore government have built 4 high-tech reclamation plants in the country, called NEWater Plants, as well as a vast underground system of pipes to move both wastewater and the recycled, disinfected water around the country.

Progressing towards 2060 targets

In 2017 595 million cubic metres of reclaimed water was used in Singapore, equivalent to 238,000 Olympic swimming pools and met approximately 30% of total water demand. By 2060 the government is aiming for 55% of total water usage to be served by reclaimed water, just 1 year before the water import agreement with the Malaysian government is due to end.

In April 2018, Singapore’s national water agency PUB has broken ground for the second phase of the underground pipework – referred to as the ‘enhanced conveyance system of the Deep Tunnel Sewerage System’ – to deliver ever more wastewater to the NEWater plants for recycling. The technological progression is still a keen focus for the Singapore water agency, as University researchers are working on methods of desalination that mimic the human kidney, while engineers work to reduce the energy consumption of wastewater recycling plants.
