Hasco has developed the H5055 hole filter for demanding filtration tasks in mouldmaking. The component, produced from corrosion resistant stainless steel, is intended for installation in machine nozzles and sprue bushings. According to the company, the solution targets efficiency, durability and process reliability in injection moulding operations that are sensitive to contamination and pressure losses.
The design incorporates more than 1,000 holes and is distinguished by angled bores that guide and stabilise the melt flow. This geometry is intended to reduce shear, helping to maintain the mechanical properties of the processed polymer while minimising pressure drop across the filter. A conical layout distributes the melt evenly across all openings, which supports uniform flow and mitigates localised stress. In addition, the arrangement enables contaminant particles to accumulate on the outer surface, from where they can be removed without disassembling the filter. This feature is aimed at simplifying routine maintenance, extending component life and reducing unplanned downtime during production.
In practice, the H5055 is positioned as a high performance, low maintenance option for applications that run filled and potentially abrasive compounds. By combining corrosion resistant materials with a flow optimised internal structure, the filter seeks to maintain stable processing conditions over longer intervals, particularly where melt cleanliness and consistent pressure are critical to part quality.
Proven performance at Magnetfabrik Bonn
At Magnetfabrik Bonn the new Hasco hole filter H5055 is already in use under challenging conditions. The processor runs moulding compounds with abrasive metallic fillers, with filler content higher than levels typically encountered in MIM and CIM injection processes. In this environment, the company reports reduced processing loads and longer service intervals.
"The results speak for themselves," says Marcus Mohr, Head of the Toolmaking Division at Magnetfabrik. "We were able to reduce injection pressures by around 20 percent while maintaining high part quality and significantly extending service life." Filter cleaning has also been simplified, with impurities collecting on the outside for easy removal. "The new design convinced us. We are now gradually converting our production to the new model," adds Mohr.
Customer feedback and process stability
Magnetfabrik Bonn has collaborated with Hasco for more than two decades. Sales Manager Frank Burilov underscores the practical impact of the latest development: "Hasco supports us with innovative products and practical solutions, helping us to stabilise our processes and further enhance quality." In line with this feedback, Hasco positions the hole filter H5055 as a durable, efficient and reliable addition to its product range, particularly where low pressure loss and repeatable operation are required in everyday production.
