Efficient and highly precise
Tailor-made machines from Zubler Handling
The production systems in the plastics industry are highly automated. This extends far beyond the actual production of injection moulded parts. Post-production processing in particular is extremely complex. Zubler Handling AG from Uzwil SG is a specialist in manufacturing tailor-made machines and excels in this niche.
“Injection moulded parts are removed from the mould, measured, inspected, stacked, packaged and labelled on the tailor-made automation systems from Zubler Handling,” explains Remo Müller, Head of Purchasing and Manufacturing at Zubler Handling AG. Among the plastic products processed with the company’s machines are, for example, precision parts for medical technology, packaging for the food industry and much more.
The machines come into direct contact with the finished plastic parts and one of the challenges in post-processing is handling the parts, which are often only millimetres in size, without damaging them during mechanical conveying. Furthermore, plastic parts for laboratory technology are produced in cleanrooms, which requires additional requirements. Abrasion, for example on conveyor belts and gripper arms, must be avoided at all costs. Therefore, various parts that come into contact with the plastic parts require very good slip properties. “Everything must run cleanly and precisely,” explains Remo Müller.
High productivity required
Zubler Handling machine parts are coated with ALTEF® or EMATEF®, depending on the application and function of the component. EMATEF® is mainly used for parts where superior slip properties are required. It provides a low roughness value, eliminating the need for expensive finishing (polishing). “We have a long-standing collaboration with Altefco in this field and are very satisfied,” says Remo Müller. “As a tailor-made machine manufacturer, we often need to react quickly. When the pressure is on, Altefco is there to back us up. They are very reliable.”
The plastics industry is highly competitive and Zubler Handling operates internationally. The Uzwil-based company offers its customers a comprehensive service, from engineering through to commissioning, maintenance and repairs. “Efficiency and productivity in the manufacture of our machines is essential for us to remain competitive,” says Remo Müller. “Altefco also supports us on this front. The company meets deadlines and delivers the best quality. And we have virtually zero rejects from the coating process.”
“Suter Industries supplies anti-hopping clutches to race teams, motorbike manufacturers and dealers worldwide. They are characterised by a high degree of hardness and bond strength – and they look beautiful. Altefco is a technical leader in aluminium coating and ANOTEC® meets our high requirements. We are particularly impressed by the dimensional accuracy, the consistently high quality and the elegant visual appearance of our finished clutches.”
Elegant and safe
Motorbike clutches from Suter Industries
The company Suter Industries from Turbenthal ZH has been using ANOTEC® from Altefco for coating motorbike clutches for over 20 years. Their flagship product, the “SUTERCLUTCH”, is extremely popular with racers, motorbike manufacturers and motorbike enthusiasts alike owing to its sophisticated engineering.
People who ride motorbikes do so out of passion. They take special care of their own bike, because it should offer maximum safety on the road and also look great. Suter Industries, a vehicle supplier in the motorbike, bicycle and energy sectors, is a manufacturing company with 45 employees. The company’s best-known products are anti-hopping clutches for motorbikes, of which it produces several thousand per year. Suter Industries supplies racing teams, various motorbike manufacturers and end customers.
Suter Industries has relied on Altefco as a coating partner in this area for over 20 years. “Altefco is the technical leader when it comes to aluminium coatings,” sagt Roger Sutter, production manager at Suter Industries. The collaboration developed, however, also because of the geographical proximity: “For us, it is easy to deliver and collect the parts in nearby Thurgau.” Altefco is also unrivalled in terms of processing speed: “A job usually takes a week – if it’s urgent, Altefco can do it in two days.”
Hardness and bonding strength are crucial for the coating of motorbike clutches. That is why Suter Industries has opted for hard anodising with ANOTEC®. The process involves applying a layer of aluminium oxide, which protects the clutch from wear and corrosion. The surface of the base material is transformed in the process. This means that half of the coat thickness ‘grows’ into the base material, so that a standard thickness of 40 µm (40/1000 millimetres) results in an application of 20 µm. “We are particularly convinced by the dimensional accuracy,” says Roger Sutter. “Altefco’s coatings are always exactly the same thickness. We can rely on that.”
There is another good reason why Suter Industries works almost exclusively with Altefco for its motorbike clutches: “Our customers want their motorbike to look great,” says Roger Sutter. “An elegant appearance is therefore particularly important to us. ANOTEC® enables us to achieve this as well.”
“We manufacture machinery for the chocolate industry. The core components of our systems are treated with an ALTEF® coating, which makes them harder and more scratch-resistant. Additionally, the surface gains better slip properties. Altefco provides exceptionally good consulting services. They help us whenever necessary and respond very quickly to inquiries. Adherence to delivery dates and consistent quality are further reasons why we have chosen Altefco.”

Robust and versatile
Chocolate production lines from TRIKNO AG
In chocolate production, versatility is the name of the game. TRIKNO AG from Felben-Wellhausen specialises in chocolate and confectionery machines and stands out for its customised solutions. The Thurgau-based company relies on Altefco for its aluminium coating.
The production of a praline is a highly complex matter. The initially liquid chocolate goes through a whole series of production steps on its way to becoming a finished confection. Starting with the production of the chocolate mass, to the moulding of hollow forms, to the brief stop on a vibration table for consistent shell thickness, to pouring in the filling, to preheating again under a bonnet, and finally to garnishing with nuts or other delicacies. TRIKNO AG specialises in such production lines and is represented with its equipment at almost all the major chocolate brands in Switzerland. “We cater to the individual needs of our customers and also offer prototype construction,” says Joël Michel, Head of Purchasing at TRIKNO AG.
Customer from the very beginning
For more than ten years, TRIKNO chocolate production line machine parts have been treated with aluminium coatings. “We have already had over 6800 parts coated at Altefco. We opt for ELOX and ALTEF® coatings,” says Joël Michel. The core parts of the production lines are coated with ALTEF® – this makes them harder and thus more scratch-resistant. It also increases the slip properties of the chocolate mass on the surface. External machine parts are given an ELOX coat – making them more corrosion-resistant and visually more appealing.
For the ultimate chocolate experience
It is particularly important for TRIKNO that both types of coating meet food safety standards: “We have to comply with many requirements in terms of food safety. The end product must not be contaminated. Altefco’s process puts us on the safe side,” explains the chocolate production expert. “Another advantage the coatings offer is extra protection when cleaning the machines.”
Machines are cleaned often, and when a product change is due, chocolate producers have to make sure that not even the smallest remnant of the previous product is left in the machine.
A partnership on equal terms
“Altefco’s aluminium coatings are not just surfaces, they bond with the material underneath and as a result are very durable,” says Joël Michel.
In addition to pralines, a wide variety of chocolate confections can be produced on TRIKNO lines – from simple chocolate bars to Easter bunnies and from chocolate bananas through to truffles or biscuit fillings. “Altefco has been familiar with our parts for a very long time and they have given us some good tips. We also get an immediate response when we have questions.”
