High-speed aerodynamic filament stretching onto high-porosity forming belt conveyors
Thermal bonding calenders with micro-adjustable roll nip pressure and surface thermal zones

Alignment and Cleaning Protocol for EVO Blown Film Die Heads

Uniform thickness distribution in Reifenhäuser EVO blown film extrusion systems relies on meticulous cleaning of the coextrusion die head and precision calibration of spiral mandrel gaps.

During scheduled servicing or resin grade changeovers, the tooling is freed from polymer degradation using soft brass scrapers at molten polymer temperature. Die head assembly bolts are tightened using calibrated torque wrenches following an opposing criss-cross pattern.

The dual-lip external air ring and internal bubble cooling (IBC) plenums are purged with dry shop air to eliminate turbulent air swirls that induce film gauge variations across the bubble.

Radial Clearance and Flight Geometry Inspection of Reiloy Screws

Minimizing mechanical abrasive degradation and preventing melt backflow inside Reifenhäuser extruders requires periodic measurement of Reiloy screw flights.

During comprehensive inspections, the screw shaft is pulled hot using designated puller fixtures and positioned on precision roller v-blocks to verify radial runout with a dial gauge.

Hard-facing ridge thickness and radial flight-to-barrel clearance are measured with micrometers across metering and barrier sections. Timely detection of wear along ReiMix-HS mixing elements enables plant managers to schedule laser cladding refurbishments or replacement shaft fabrication.

Maintenance of Reiloy Bimetallic Extruder Barrels

Reiloy bimetallic plasticizing barrels produced via specialized centrifugal alloy lining require systematic inspection of their internal bore and liquid cooling circuits.

During preventative shutdowns, technicians perform borescope inspections of the inner lining to detect flaking, corrosive pitting, or groove wear. Temperature conditioning channels are flushed with descaling solutions to prevent mineral build-up and maintain design heat transfer rates.

The replaceable grooved feed bush is examined for scoring along intake grooves, which would otherwise disrupt resin feeding into the compression zone.

Calibration of Planar Dies with Rapid Flex and PAM Systems

Homogeneous melt flow across wide extrusion widths on Reifenhäuser planar die heads depends on precise setting of Rapid Flex flexible lips and PAM automated actuator drives.

Prior to production startup, the die body is preheated through controlled thermal ramp-up stages to equalize internal metal temperatures. Motorized PAM actuator tuning works in closed-loop operation with non-contact beta or x-ray thickness gauges to correct narrow-band gauge variations.

Regular cleaning of polished die exit lips using high-purity copper blades prevents die lines and optical defects on the cooling film web.

Diagnostic Procedures for Grooved Feed Zones and Extruder Drives

Consistent pellet feeding and steady pressure generation in Reifenhäuser single-screw extruders rely on optimal operation of the grooved feed housing and synchronous powertrain.

Maintenance routines include monitoring feed throat cooling jacket temperatures to prevent premature polymer melting and hopper bridging.

Drive train maintenance encompasses periodic analysis of synthetic gear oil, inspection of heavy-duty spherical thrust bearings absorbing screw backpressure, and flexible shaft coupling alignment checks. Preventative vibration monitoring detects early gear mesh degradation prior to line stoppages.

Cleaning Protocol for Reicofil Spinning Beams and Calenders

Producing uniform spunbond and meltblown webs on Reifenhäuser Reicofil nonwoven lines requires pristine cleanliness of micro-capillary spinneret beams and thermal bonding calenders.

Extrusion spinning packs are dismounted and cleaned in vacuum pyrolysis ovens followed by ultrasonic cleaning baths to dissolve residual polypropylene without damaging fragile capillary holes.

On the thermo-bonding calender, hydraulic cylinder nip pressures and oil-heated roll surface temperatures are verified with infrared pyrometers. Calender roll finishes are inspected regularly to maintain tensile web bonding properties.
