The filter’s design features more than 1,000 holes, making it unique on the market. It reduces shear, helping to preserve the mechanical properties of the plastic while minimising pressure loss. Thanks to its sophisticated structure with angled holes, melt flow is optimised, shear stress is reduced, and pressure drop is kept to a minimum. The conical geometry ensures the melt is evenly distributed across all the holes. Sediment can be removed from the outside with ease — reducing maintenance, extending service life, and minimising machine downtime during production.

At Magnetfabrik Bonn — one of Germany’s leading manufacturers of high-quality magnets — the new Hasco hole filter H5055/... is already in successful use.

“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.” This performance was achieved under extreme conditions. The moulding compounds used at Magnetfabrik contain abrasive metallic fillers, with filler content exceeding the typical levels found in MIM and CIM injection processes.

Filter cleaning has also been simplified: impurities collect on the outside and can be removed easily. “The new design convinced us. We are now gradually converting our production to the new model,” adds Mohr.

Magnetfabrik Bonn has worked successfully with Hasco for over two decades. Sales Manager Frank Burilov highlights the strength of the partnership: “Hasco supports us with innovative products and practical solutions, helping us to stabilise our processes and further enhance quality.”

With the hole filter H5055/..., Hasco adds a high-performance, low-maintenance, and long-lasting solution to its comprehensive product range. The filter delivers excellent results with low pressure loss, high efficiency, and reliable performance — even under challenging production conditions.
