Engineering selection of plasticizing screws and barrels

Selection of replacement plasticizing screws and alloy barrel sets for Fuyang Horong machines relies on original machine nameplates or technical drawings of worn assemblies.

When molding abrasive polymers reinforced with 30% glass fibers like PBT-GF30 and PA6-GF30, bimetallic barrels with tungsten carbide internal lining and screws with welded flight tops reaching 58 to 64 HRC are recommended.

For standard unreinforced polymers including polyethylene, polypropylene, and ABS, ion-nitrided 38CrMoAlA alloy assemblies providing 950 to 1050 HV surface hardness ensure long operational lifespan.

Assemblies include the barrel cylinder, plasticizing screw, mixing tip, check ring, and injection nozzle.

Inspection and maintenance of direct hydraulic clamping units

Direct hydraulic clamping units on Fuyang Horong HR-160 through HR-2500 vertical molding machines deliver uniform clamping distribution without toggle linkage deflection.

Routine preventative maintenance involves inspecting tie bar alignment, checking bronze guide bushings on the moving platen, and replacing hydraulic piston seals on the primary clamping cylinder.

If locking pressure drops below setpoints, technicians check piston cup packings and proportional pressure valve calibration. The low-pressure mold safety system prevents high-pressure platen closing whenever inserted metal terminals shift, protecting expensive tooling dies.

Adjustment of shuttle and rotary indexing tables

Vertical machines from Horong featuring HR-S shuttle platen tables and HR-R rotary indexing tables demand precise alignment of mechanical stops to avoid mold shift during injection.

In shuttle machines, table traversal force is supplied by a hydraulic cylinder with position feedback from magnetic switches or linear transducers.

In rotary HR-R units with dual or triple station indexing platens, smooth deceleration of the rotary drive and solid engagement of tapered locating pins before platen closure are critical. Regular lubrication of slideway gibs and proportional throttle calibration prevent pressure spikes.

Processing parameters for thermoset and Bakelite machines

Molding components from phenolic resin, Bakelite, and polyester BMC compounds on Fuyang Horong HR-550BMC machines requires strict thermal separation across zones.

The plasticizing barrel is fluid-cooled via thermal oil recirculation to maintain melt temperatures between 70 and 90 degrees Celsius, preventing premature resin polymerization within screw flights.

Tooling heaters conversely maintain mold temperatures between 150 and 175 degrees Celsius for rapid curing. Thermosetting production relies on a specialized shallow-flight screw with minimal compression ratio and an open reverse-taper nozzle.

Hydraulic circuit maintenance and proportional valve calibration

The hydraulic system of Fuyang Horong vertical injection molding machines runs on Shell Tellus 46 or Mobil DTE 25 industrial fluid under working pressures up to 140 bar.

Ensuring repeatable shot metering and smooth platen movement requires dual proportional electrohydraulic valves for fluid pressure and volume regulation.

Maintenance schedules require annual oil replacement, monthly cleaning of suction strainers, and scheduled replacement of 10 to 15 micron return filter elements. Hydraulic oil temperatures above 55 degrees Celsius accelerate vane pump wear, making oil cooler performance essential.

Microprocessor control system and thermal regulation

Microprocessor controllers on Fuyang Horong machinery handle digital sequence execution for platen clamping, injection phases, holding pressure profiles, and screw decompression.

Multi-zone PID temperature controllers keep barrel zones regulated within one degree Celsius via solid-state relays and type J or K thermocouple probes. When temperature drift, cycle timeout, or light curtain interruptions occur, the operator interface displays diagnostic fault codes.

Upgrades for machine fleets include modernized input-output modules, touchscreen operator terminals, and proximity limit sensors.
