KRÖNER FILLING TECHNOLOGY MODULAR, RELIABLE, EFFICIENT.

The term “Filling technology” refers to all product-side components required for the controlled feeding of particle foams into the mold. These include injectors in various designs, material connections, fluidizing nozzles, silo components, and associated accessories. These components are essential to the foaming process and play a crucial role in process reliability, repeatability, and product quality. Our in-house developed and manufactured injectors feature a modular design that allows them to be precisely tailored to customer-specific requirements. From just six base models, more than six million possible variants can be configured - ensuring maximum flexibility while maintaining consistent standardization. The accurate selection and combination of these components not only ensures stable filling but also enables efficient maintenance, short setup times, and high system availability.

INTEGRATED EJECTOR SYSTEMS

In integrated ejector systems, the injector’s piston rod can assume three positions: injector open, injector closed, injector extended to the front (ejection). The most common reason for using injectors with an integrated ejection function is limited space on the mold or the wish for pneumatic ejection. We offer various designs that can be selected based on the machine control system, the number of injectors on the mold, and the geometric characteristics of the molded part

INJECTOR MAINTENANCE AND REPAIR

Regular maintenance increases the service life of the injectors. For this purpose, we offer a wide range of seal kits and assembly tools. More extensive maintenance or repairs can be carried out at our facility. The injectors will be inspected, and a cost estimate will be provided to assess the economic viability of the repair. In case of an order, the injectors will be restored to optimal condition using original spare parts. Please contact us for more information
