New deflashing system from C.S.I. (Centro Servizi Industriali) removes need for cryogenic pretreatment.
C.S.I. - Centro Servizi Industriali has recently introduced the MF-15L macrofinishing machine, an innovative system that removes runner and overflow flashing from injection-moulded elastomer parts automatically, without the need for prior cooling in liquid nitrogen. This energy-efficient process reduces both production costs and environmental impact.
Traditionally, elastomer components such as O-rings
and other moulded parts required manual removal of flashing along the parting line and gates, or a classical cryogenic tumbling process. With the MF-15L, this step is now fully automated, eliminating the need for liquid nitrogen and significantly reducing finishing effort.
The modular system operates largely autonomously. After placing one or more raw parts onto the feeder belt, no further manual handling is required. Once processed, the parts emerge largely free of gating material and coarse flash. Parts are batch-fed into the rotating, studded container, which mixes the material intensely. This separates the parts from the gating material while removing excess flash. The process takes 20 to 40 seconds, after which parts and separated flash are transferred to a downstream sieving section. Any minor remaining flashes can then be removed in a secondary step using mass finishing or nitrogen deflashing, if necessary.
“The MF-15L operates solely on electricity, requiring around 5 to 8 kW. This reduces process costs and environmental impact by avoiding nitrogen production and polycarbonate blasting media. Our customers also benefit from a lower carbon footprint,” has stated Dieter Adamkiewicz, Managing Partner at C.S.I.
