Poeton offer a comprehensive coating service for the food and drinks industries, meeting the challenge provided by the demands for cleanliness and food compatibility. We produce a wide range of advanced polymer coatings for parts used on food processing and packaging equipment to provide wear resistant, non-stick, low friction and non-wetting surfaces. They are designed to keep machinery and equipment working 24/7, with the minimum of disruption, whether it's sorting, packing, filling, moulding or printing.

Typical Apticote Applications in the
Food and Drink Industries

  • Mixers and stirrers
  • Moulds and trays
  • Hoppers and dispensers
  • Extruders
  • Rollers and presses
  • Conveyors, chains and pulleys
  • Heater plates
  • Food packaging machinery
  • Bottle handling machinery
  • Sealing plates and knives
  • Seal faces
  • Food pump parts, splines and couplings
  • Food labelling machines
  • Food sorting machines

We are at the forefront of surface coating and treatment suppliers to some of the world's leading food and rink companies, and one of our crucial advantages is our technical support and laboratory backup. Using our expertise in characterising and understanding wear and sticking processes, we work with our customers on a project basis, ensuring that the most effective coating solution is identified.

Features

Application areas and benefits

Apticote 200 Polymer coatings A family of polymer coatings offering non-stick, low friction and wear prevention. Parts include moulds, tray, sealing plates, heater plates and trays. Poeton will advise on which of the Apticote 200 coatings is best for a given application, and on the question of food compliance*
Apticote 810 Graded polymer composite coatings A family of graded, composite polymer coatings offering unique non-stick. They solve the eternal problem - how to get a non-stick coating to adhere to a metal substrate, at the same time as being non-stick to the food product. Parts include sealing plates and other applications where there is high contact pressure, situations which will dis-bond a normal non-stick polymer coating. Poeton will advise on which of the Apticote 810 coatings is best for a given application, and on the question of food compliance*
Apticote 300 Hard anodising Our hard anodising provides exceptional low stress abrasive wear resistance, and is suitable for lightweight structural parts that might be subject to wear or erosion by food products, such as dried fruit or vegetables. Parts include chutes and conveyors on sorting and dispensing machines
Apticote 350 and
Apticote 355
Composite hard anodising of aluminium A range of anodic specialised processes with polymer infusion, providing exceptional wear and corrosion protection (up to 15000 hours salt spray) for aluminium alloys. Parts include trays and moulds.
Apticote 400 A high quality electroless nickel coating Ideal for precision parts needing anti-fretting and corrosion protection, on parts such as splines, couplings and conveyors.
Apticote 450 An electroless nickel/polymer composite Providing very low friction, wear resistance and anti-fretting. Good for anti-galling on threads, and for parts on conveyors and chains where no lubricant is permitted.
Apticote 460 An electroless nickel/polymer composite Providing more wear resistance than the A450 variety, with low friction and exceptional non-stick. Poeton will advise on which of the Apticote 460 range is the most suitable for your application.
Apticote 800 Thermally sprayed coatings We offer a wide range of cermets and ceramics for wear resistance on food machine parts that might be subject to heavy abrasion, including stirrers and mixers. Poeton will advise on which of our many coatings is the best choice for your application.
Apticote Keronite 3000 An electro-ceramic coating for aluminium. The ultimate wear protection for parts made in lightweight aluminium alloys subject to abrasion by aggressive food products

Case Histories

Chocolate extrusion

Advanced non-stick coatings for the food industryProblem -Our customer had a particularly sticky problem with chocolate. The product was extruded at high pressure, between two counter rotating rollers, with dies and fingers, and the normal Teflon non-stick coatings were squashed, and peeled off within 40 hours. Then the chocolate stuck - with very messy consequences.

Solution - Poeton looked at the problem from a point of view of contact stress, calculating that the peak shear forces were actually below the coating, in the substrate. No wonder a normal non-stick polymer couldn't cope.

We recommended a much tougher, graded coating, our Apticote 810 system, with a coating substrate bond that could stand up to the high contact stress, whilst the surface provided unrivalled non-stick.

The company quote was, "After coating with Apticote 810, our extrusion machine performed beautifully. No peeling. No bare metal. No release problems at all. That was over two years ago, and those extruder dies and fingers are still exhibiting excellent on-the-job performance.

Abrasive peas

Advanced non-stick coatings for the food industryProblem - Peas are unexpectedly abrasive. As they tumbled down the chute under the eye of the sorting device, they were wearing away the aluminium extrusion at an alarming rate. Our customer needed a food compatible coating that could withstand the harsh conditions.

Solution - This was not a job for conventional hard anodising. The problem was one of erosion, rather than sliding abrasion, with an element of low angle impact and sub-surface stresses. Poeton solved the problem with our Apticote 300M anodising system, with a coating that could stand up to the high contact stress, whilst the surface provided unrivalled wear resistance.

Now the machines last for years, not weeks!
