FSC OEM-Compact Design - Flat Screen Changer for Processing of Plastics

Oct 3, 2026

Upload by Eliana

FSC OEM-Compact design presents an ultra-compact flat screen changer for plastics processing lines, engineered to reduce equipment footprint and residence time while improving residence time distribution. Short, flow-optimized channels minimize pressure drop, support uniform product temperature, and maintain precise flow at high discharge pressures. The complete package cuts pressure loss and material consumption, increases production rate, improves product quality and energy efficiency, and extends equipment life. It also emphasizes maintenance-friendly access to the sealing package, with defined technical limits for viscosity, temperature, and pressures.

FSC OEM-Compact Design Optimized ﬂat screen changer for processing of plastics The ﬂow optimized new version of MAAG´s FSC hydraulic and manual screen changers assist operators of plastic extrusion lines in achieving a reduced equipment footprint, reduced residence time and improved residence time distribution. The ultra compact design is maintenance friendly, and provides precise ﬂow even at high discharge pressures. The ultra short ﬂow channels reduce pressure drop, promote a more uniform product temperature, allowing this generation of screen changer to perform where others have reached their limits. Superior performance beneﬁts compared to existing designs Holistic design of the complete screen changer package results in many major improvements: 􀂃 Reduction in pressure loss, residence time and residence time distribution due to shorter, ﬂow optimized channels 􀂃 Increased production rate, product quality, energy efﬁciency and equipment life span 􀂃 Elimination of pressure ﬂuctuations allowing a signiﬁcant reduction in rate of material consumption 􀂃 Maintenace friendly due to easy access to the sealing package FSC OEM Flat screen changer for processing of plastics Technical speciﬁcations screen changer: Housing, cover: Alloy steel | Slide plate: | Hardened alloy steel | | | --- | --- | --- | | Breaker plate: | Hardened alloy steel | | | Heating: | Electric / liquid | | | | | | | Application limits: | | | | Viscosity: | | from 10 to 10,000 Pas | | Temperature: | | up to 325°C | | Operational pressure: | | up to 700 bar | | Diffential pressure: | | up to 200 bar | breaker plate channel insert sealing ring slide plate sealing ring expandable ring Typical range of products 􀂃 Polymer melts such as: LDPE / HDPE / HIPS / ABS / PET / PP / PS / PC / PBT / PLA / PA6 . 􀂃 Speciﬁc melt density range of 0.73-1.7 􀂃 Special materials, like silicon rubber or ﬂuorinated polymerson request Accessories 􀂃 Base and support cart 􀂃 Adapter ﬂanges standard 􀂃 Pressure and melt temperature transducers 􀂃 Drive systems, controls and complete system solutions Sealing technology Different application in melt ﬁltration require ﬂexible sealing systems which can manage low viscosities and challenging high operation temperatures.
