PELLETISING SYSTEMS | MACHINERY
Nordson has recently built a dedicated produc- tion line for die plates used in its BKG underwater pelletising equipment at its plant at Münster in Germany. Die plates are wear components which must be periodically refurbished or replaced. While the most common die plates are held in stock and can typically be delivered within a couple of days, delivery times for less common plates can be significantly longer.
Cutting lead times The combination of the new dedicated production with a database of standard design elements has allowed the company to eliminate certain upstream engineering processes that had contrib- uted to longer lead times. As a result, it can now deliver many of its electrically-heated die plates in just three weeks from order placement (including order entry, engineering and production). “The dedicated production line for die
plates enables Nordson to meet the needs of customers much more quickly, helping then to reduce downtime and maintain product quality,” says Andreas Trouvain, Sales Director EMEA for Nordson’s BKG product line. At present the capability is limited to two-piece, electrically-heated die plates for BKG A, AH, Compact, and AHD190 families, which it says comprise the largest share of its die plate output. These are available with the most common nozzle bore diameters and with optional features such as different carbide inlays, thermal insulation layers, pressure reduction, nozzle bore configurations, and both standard and short land lengths. “We continue to expand the range of designs
that can be produced in this line, and we are looking for more ways to shorten the processes upstream and downstream of die plate production in order to make lead times even shorter,” Trouvain says. Nordson continues to offer fully custom designs where required for specific customer applications. Success with recycling companies is a highlight for Germany-based ips Intelligent Pelletizing Solutions. Recycler Inoplast Kunststoff has put an automated ips-SGU 120/2 underwater strand pelletiser from ips into operation at its Windische- schenbach facility in Germany. It is used to produce high-quality recycled materials from PET and PA waste.

Inoplast’s main focus is contract recycling of
production waste, returning customers’ plastic scrap as high-quality recycled material. It replaced its previous strand pelletiser with the automated underwater strand pelletisng system in order to increase output and reduce waste. The ips-SGU 120/2 system at Inoplast is inte-
grated with the ips-PWS 200 A process water system and ips-GT 1200 pellet dryer. Alexan- der Müller, Managing Director at Inoplast, says: “We were more than convinced by the fact that the plant is more in line with our require- ments, the outstanding expertise of the ips team in the recycling branch and the ‘Made in Germany’ quality.” Gerald Weis, owner and Managing Partner of ips, says:
“The ips underwater strand pelletising system has been designed particularly for the special requirements of PET and PA recycling.” The system features a strand feed with rounded start-up head and flexibly
adjustable extrusion heights as well as a hinged spray nozzle unit for simple and fast access to the cutting head. The cutting gap consistency is achieved through simple adjustment options with the cutting head. All plant parts, such as the process water system with band filter unit and pellet dryer, are mounted on a joint machine frame. Ips says the system achieves a throughput of up to 1,500 kg per hour of granulate. “Thanks to the modular product system, we can
respond to the individual wishes of our customers and tailor the system exactly to their needs,” says Weis. The company is able to offer complete pelletis- ing systems, consisting of a strand feed, the process water distribution system, the actual underwater strand pelletiser, post-cooling section with agglomerate catcher and water jet pump, pellet dryer, process water system and complete control. With the ergonomic ips operating system, the complete plant is controlled by means of a graphic touch screen user interface. Automatic start-up and shutdown can be done at the touch of a button.
Ips has developed a new product, the ips-DR/K option for its underwater pelletising systems for the inline crystallisation of recycled PET material. The ips-DR/K rotary drum, with its compact, horizontal design and dedicated process guid-
