Our customer, GJD designs, produces and sells intruder detection products at its factory and head office in Heywood, Greater Manchester.

One of GJD’s main products is its line of white-light and infra-red LED illuminators, marketed under the company’s Clarius® brand. Used principally in security applications, they also find other uses, including broadcast production. High performance and optimum reliability are essential when considering that many installations are subjected to rigorous weather conditions. All products in the range are IP66 rated and UL Listed.

Automated dispensing helps security manufacturer increase throughput and quality
The preeflow eco-PEN 600 delivered increased the accuracy of dispensing volumes

Constantly driving for product and process improvements, Operations Director John Hale was seeking a way to improve the way that the plastic lens was bonded to the extruded aluminium housing. Previously, a silicone had been applied manually from a 310ml cartridge. This was a time-consuming, ergonomically unsatisfactory process, which also resulted in material waste and clean-ups. Operators’ inclination was to apply excessive silicone to ensure an effective seal, but this was oozing out on both the outside and inside of the assembly when the lens was applied. John’s initiative coincided with an approach from a multinational company to manufacture selected products for global distribution.

Concluding that an automated silicone dispensing solution would provide the best solution, John visited our Technology Centre in Kidlington, Oxfordshire to carry out dispensing trials with GJD’s assemblies. This resulted in the purchase of a Fisnar Dispensing Robot with a pneumatic dispensing valve, fed from the cartridge. The robot and valve combination led to substantially improved efficiency. After 14 months, in the interest of better repeatability, accuracy and production rates, it was decided to further upgrade to the preeflow eco-PEN 600 precision volumetric, positive displacement dispensing pump, which delivered even more accurate volumes.

The eco-PEN offers ±1% dosing accuracy, >99% repeatability and can dispense volume flows of 1.4ml to 16ml per minute. Four months later, a second, similar system with upgraded robot was purchased and installed for a new product line, as well as providing a back-up for the original system. The Fisnar robot combines precision positioning, simple step-by-step programming and compact footprint.

The original and subsequent installations were carried out by our technical team, who also supplied and integrated the dispensing controllers and requisite tooling and bracketry. Both systems are fitted with preeflow flowplus16 compact inline fluid pressure sensors, providing continuous flow monitoring for guaranteed process assurance.

John Hale said:

It has really helped with consistency: we know we’re going to get the same amount of silicone dispensed and that the product is going to be correct every time.

Our Illuminators carry a five-year warranty, so they have to be able to stand the test of time. Making sure that the silicone is consistently applied is a critical component in our production process. Also, with increased demand, moving from a manual process to an automated one has allowed us to get a lot more through production.

I’m very happy with the equipment, the way it works and the way it has been integrated into our processes.

Commenting on Intertronics as a partner, John continued:

One of the things that impressed us has been the support we’ve received. Any investment you make, once you’ve made that decision, there’s an element of hope that the support will be there, and I can say it certainly has been with Intertronics.

We’ve worked with the Intertronics team to develop the equipment to meet our needs further than when it first arrived and I’ve found that it’s never too much trouble. Any of our guys can pick the phone up – they’ll try to diagnose over the phone, otherwise it won’t be too long until they’re on site. For anyone in manufacturing, that level of support is critical to keeping things moving. We wouldn’t have bought an additional system if we hadn’t been happy with the support we’d received.

John also estimates that material savings in the order of 30% have been achieved since the introduction of the automated silicone dispensing system.

You may already know of the Piezobrush PZ2 handheld plasma surface treatment system from our partner Relyon Plasma, which provides a simple, effective method of increasing adhesion and wetting on difficult-to-bond surfaces. If you would like your application to be semi-automated or fully automated, a version of the Piezobrush PZ2 is now available which is designed to be attached to a stand, robot or other automation.

The Piezobrush PZ2-i automatable plasma surface treatment has a number of benefits:

  • Improves adhesion & wetting of surfaces
  • Robot mountable for improving productivity, repeatability and process control
  • Uses “cold plasma”, meaning that it can be used to treat temperature-sensitive substrates
  • Uses an external gas supply such as compressed air or nitrogen

Piezobrush PZ2-i automatable plasma surface treatment on a robotThe Piezobrush PZ2-i is the world’s smallest cold active plasma unit developed for integration into industrial processes. This “cold plasma” is produced at less than 50ºC, making it suitable even for some temperature-sensitive substrates such as plastic films. This robot-mountable version of the Piezobrush PZ2 combines the effectiveness of plasma surface activation with the improved productivity and repeatability of using a robot to automate a process. The Piezobrush PZ2-i uses compressed air to operate, or can be used with other gases such as nitrogen.

If you are interested in improving adhesion or wetting of adhesives, inks or other liquids, we would be pleased to show you the Piezobrush PZ2-i. Contact our product specialists to arrange a demonstration.

James Heydon, who is a key member of our Order Fulfilment Team, has earned a Duke of Edinburgh Gold Award. We had a chat with James to find out more about his award and what it took to achieve it.

Why did you decide to pursue a Duke of Edinburgh award, and particularly to keep going to Gold?
When I decided to pursue a Duke of Edinburgh award, Gold (the highest level of achievement) was always my target. I started my DofE through the scout movement, and working with the Yarnton order phentermine 37.5 mg Scout Group who kept me motivated to pursue the Gold award. Yarnton Scout Group gave a platform for everyone to excel, and if it wasn’t for them, I’m not sure I would even know what the Duke of Edinburgh award was, let alone achieve the Gold award and meet the Earl of Wessex! My parents also motivated me to get on and complete the expedition part, which was my last section, and finish the award. The Gold award must be achieved by the age of 25; I have completed it at only 21.

What activities have you done to earn the award?
The components of the Duke of Edinburgh Gold award are volunteering, physical, skills, expedition, and a residential task. I began by volunteering at the local cub pack at Yarnton Scout Group and never left – I’m now an assistant cub scout leader (or ACSL for the scouting people!). My expedition consisted of a 4 day/3 night canoeing trip, and my residential task involved spending a week redecorating a homeless centre in London.

What happened at your ceremony?
The ceremony took place at Buckingham Palace, which involved an early morning start and a higher level of security than I typically encounter on a weekday! We had the opportunity to walk around the gardens before the ceremony, which then featured the Earl of Wessex (Prince Edward) and Mount Everest climber Jo Bradshaw. I now have a lovely certificate to enhance my sense of accomplishment.

Now that you’ve reached Gold, what are you going to do next?
Well, I have definitely gained a lot through Yarnton Scout Group and I would like to continue giving back by remaining on as a leader with the cub pack and taking an active part in weekend activities (such as scout camp this weekend).

Needless to say, we are immensely proud of James and his attainments. It is indicative of the drive and tenacity of our team, and the need to be the best that we can be.

adhere academyWe will be sharing our knowledge of adhesives next week on Friday 2nd June 2017 in a seminar entitled The Art and Science of Choosing a Structural Adhesive at The Engineering Materials Show, Derby.

The seminar, delivered by Peter Swanson, will focus on how to choose and evaluate the best adhesives from the increasing number of structural adhesives on the market available for your application. Starting with design and working through production and processing considerations, the seminar will discuss the various factors which will influence your decision, and how to develop a specification based on necessary priorities and allowable compromises. Though there is no universal adhesive which works for everything, the seminar will equip you to select adhesives by understanding what questions to ask and to whom, the different types of adhesives and chemistries, weighing up performance versus manufacturability, and deciding what your bonding priorities are for your production process.

The seminar takes place within the The Engineering Materials Show, at the The Roundhouse in Derby. Entry is free, but by pre-registration only, so don’t delay to book your place.

We will be on our stand (OR7) all day so please come down and chat to us, we’d love to see you!


In the impressive world of nanotechnology, getting to even smaller scale is increasingly important. For example, pharmaceutical companies who want their drugs to be faster acting on patients are considering nanoparticle formulation to improve the dissolution rate and solubility of their compounds.

The THINKY NP-100 Nano Pulveriser breaks up particles using impact fragmentation, taking larger particles down to nano-size. In a controlled process taking only minutes, particles in the 10 micron range are reduced to 100 nanometre sizes or less with tight particle size distribution. The THINKY NP-100 uses planetary revolution and rotation action to produce a centrifugal force on a 45° plane to create strong concentrated energy that increases collision, friction and shear force, combined with a chiller to provide temperature control. The nanoparticles are subsequently separated out from the pulverising media by using a mesh filter in a ‘Clean Media’ mode, a process which takes place in the same machine.

The THINKY NP-100 can process small quantities, down to 3 mg. Its quick operation reduces the potential for contamination from the pulverising media and containers. It is suitable for nanomaterials including inorganic pigments, pharmaceutical compounds, drug and medicines, and battery materials. Examples include naproxen, nifedipine, danazol, griseofulvin, phenytoin, indomethacin, aluminium oxide, titanium oxide, lithium carbonate and iron phosphate.
