In addition to a good price-performance ratio, FUSO requires from injection moulding machines above all stability, as well as easy access for servicing and cleaning, a smooth, easy-to-clean surface, user-friendliness in operation and a high standard of repeatability. Other factors gaining increasingly in significance are the machines’ energy efficiency, their networkability with robots and auxiliaries and availability of assistance systems.

Last, but not least, the quality of the after-sales service including the possibility of using an online service also play an important part in the purchasing decision according to Klaus Großtesner. In the acquisition of robots, easy programmability is a top priority in addition to all other criteria which are also applicable to the machines.

3D prints for rapid prototyping are also possible. Injection moulding tools and automation systems are planned, designed and manufactured in-house at the company’s own mould-making shop. For ecological purposes, the company has made a special point of installing tool-friendly cooling water systems. Further evidence of FUSO’s commitment to protecting the environment are waste heat utilisation and a photovoltaic system.

The items produced range from micro parts weighing just 0.03 g right up to large parts weighing 2 kg. In addition to manufacturing complex plastic parts by 1- or 2-component injection moulding, the company offers insert moulding for functional parts, mounting of complete assemblies, as well as gluing and welding, plus decoration by 4-colour pad printing and laser printing, and 3D scanning for reverse engineering.

To make all these parts, a number of injection moulding machines ranging from 450 to 5,200 kN in clamping force are in operation, 17 of which have come from WITTMANN BATTENFELD. Moreover, FUSO is also a long-standing customer of the WITTMANN Group for automation equipment, using more than 40 handling devices with load capacities from 5 to 30 kg, including No. 7 robots as well as latest No. 9 series models with R9 control systems.

The thermoplastic is inexpensive; one 250-gram bottle provides enough for twenty-five individuals. The dyes are also inexpensive and, since not much is needed to dye a sample, a little will go a long way. The activity is easy to do. It requires very little in the way of equipment. There is no waste and the thermoplastic can be reshaped again and again. All that is needed is hot water, a glass container and a metal spoon or wooden craft stick.

The family-owned company managed by its CEO Maximilian Högn and its CSO Klaus Großtesner makes highly sophisticated plastic parts from a great variety of materials, including high-temperature plastics, for many different sectors of industry, with about 80 workers on a production floor of just under 3,000 m².

All SmartPower machines except one are designed as Insider cells, which means that they come with a WITTMANN robot and a conveyor belt integrated in the production cell. This variant offers a number of advantages, ranging from an enormous amount of space saved compared to systems with conventional automation solutions, all the way to cost advantages from the fact that all hazardous areas are already secured and certified ex works. Moreover, the robot cycle time can be minimised due to shorter travel distances and direct parts depositing on the conveyor belt.

The company makes a point of supplying technical plastic parts and assemblies to a solid, mixed industrial customer base. The various sectors served by FUSO include the automotive and railway industries, as well as consumer goods, electronics, medical technology, building construction, telecommunication, mechanical engineering and renewable energy generation.

The cooperation between FUSO and WITTMANN BATTENFELD has already been in existence for four decades. The machines most recently supplied by WITTMANN BATTENFELD are exclusively models from the SmartPower series. The machines from the SmartPower series are hydraulic machines equipped with fast-responding servo motors and powerful constant displacement pumps. This technology, combined with the KERS (Kinetic Energy Recovery System) to recover the deceleration energy within the machine, which is included as standard, provides the SmartPower’s high level of energy efficiency. Further characteristics of the SmartPower are its small footprint and its pivotable injection unit, which ensures easy access to the barrel for quick and comfortable barrel change.

The HiQ Flow assistance system is an injection regulation function by which viscosity fluctuations in the material used can be compensated. This function enables automatic process automation and compensates even minimal fluctuations in the material quality. FUSO is so completely satisfied with this system that all of the company’s other machines have been retrofitted with it, too, wherever technically feasible and economically advisable.

When thermoplastic polymer became available a couple of years ago, we purchased a bottle to see if it would be a viable addition to our chemistry outreach program. Since then, literally hundreds of people, young and old, have experienced molding the thermoplastic, taking their creations home in Zip-loc® bags. And now, with the availability of dyes, a whole new world of creative design has opened up. The molding of a thermoplastic activity has been incorporated into our “Polymers” and “Chemistry of Crafts” hands-on outreach presentations, and has been used as a stand-alone station. Students enrolled in our Chemistry Outreach Service Learning course have employed the thermoplastic as part of their in-class group presentations. Recently, one group, as part of their holiday theme, had the class make ornaments to decorate the “chemistree,” inserting hooks while the plastic was still soft enough to hang them on the tree.

The machines delivered in 2023 also come already equipped with the new B8X control system and the HiQ Flow assistance system. The B8X control system includes several control components developed in-house. These allow a higher internal clock frequency with shorter response times to sensor signals and consequently a higher standard of parts reproducibility, with user-friendliness and familiar visualisation remaining unchanged.

“The Insider cells based on the servo-hydraulic SmartPower and WITTMANN linear robots meet our requirements in every respect”, Maximilian Högn confirms. “The equipment is space-saving, highly energy-efficient, easily accessible and easy to operate.”

With the rising demands from customers on the parts and assemblies produced, FUSO’s own demands on the injection moulding equipment used are also increasing. The company’s machinery is state-of-the-art, with a high level of automation on its production floor. All systems are fitted with matching robots to ensure careful parts handling.

Thermoplastics are a class of polymers that undergo a transition from a hard crystalline solid to a soft amorphous material when heated. The temperature at which this transformation occurs is referred to as the glass transition temperature Tg. The Tg for the thermoplastic we use is 60ºC. Students are familiar with thermoplastics, such as acrylic, nylon, polyethylene, polypropylene, polystyrene, polyvinyl chloride and Teflon®. Commercially, thermoplastics are employed in consumer goods, machine parts, medical equipment and storage materials.

The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg, and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land granted to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is co-ordinated within the Office of Indigenous Relations.

Requirements from the customer base concerning quality standards and attributes of the parts in terms of tolerances, outward appearance and materials used are constantly becoming more and more stringent. FUSO scores with purchasers by its extensive technical know-how and many years of experience in making high-quality parts and assemblies. This wealth of expertise enables the company to offer top-quality solutions which are both sustainable and cost-efficient. FUSO also stands out on the market by its high supply availability and reliability towards its customers.

Joh. Fuchs & Sohn – FUSO – was established in 1947 in Waidhofen on the river Ybbs in Lower Austria. In 1964, it started off into plastic injection moulding by producing the orange-coloured lids for Ovomaltine cans.
