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.

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.

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.

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.

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.

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.

A reduction in cycle time enables manufacturers to produce more parts in less time at lower oven temperatures, noted Nova Chemicals, while a broader processing window allows them to run different part sizes and thicknesses on the same arm under identical conditions without sacrificing part quality. Processability characteristics support consolidation of traditional 3.5 and 5.0 melt index or 5.0 and 7.0 melt index grades to a single resin, added the Calgary-based chemicals company.

Two new polyethylene (PE) resins from Nova Chemicals Corp. for rotational molding are designed to accelerate production, lower cost, and improve flexibility. The Novapol TRx0338-U and TRx0535-U hexene co-monomer resins reportedly can reduce cycle times by up to 30% and provide a processing window at least 15% broader than traditional hexene roto-molding resins, said Nova Chemicals. The findings are based on extensive internal and customer testing, said the company.

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.

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.”

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.

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.

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.

With a melt index of 3.5 and a density of 0.938, Novapol TRx0338 resin is suited for molding small tanks, intermediate bulk containers, roll-out waste carts, and material-handling containers for laundry and dry bulk goods. The 5.0 melt index, 0.935 density Novapol TRx 0535 resin is suited for manufacturing toys, recreational vehicle components, kayaks, stand-up paddleboards, and custom parts.

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.

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 PE resins from Nova Chemicals reportedly can reduce cycle times by up to 30% and provide a processing window at least 15% broader than traditional hexene roto-molding resins.

“Converters are always looking to enhance their efficiency,” said Eugene Tabone, Rotational Molding Market Manager. “Our new Novapol TRx0338 and TRx0535 grades will help roto-molders leverage the fast sintering properties of these new resins to improve their molding operations.”
