Nöbelpür GS-523 fourside planer moulder machine with control panel and extended outfeed table
  • Nöbelpür GS-523 fourside planer moulder machine with control panel and extended outfeed table

    Fourside Planer Moulder GN-5S23, GN-6S23

    Soukup
    A cast iron four-side moulder built for medium-to-high volume production, where consistent profile quality and repeatable setup matter more than anything else. Available in 5, 6, 7, or 8 spindle configurations to match your profile complexity.

    Typically chosen by

    • Timber processing operations running consistent profiles at volume who need a reliable, repeatable finish without constant re-setup
    • Joinery and furniture manufacturers who require fine surface quality straight off the machine, reducing downstream sanding or finishing time
    • Workshops stepping up from lighter-duty moulders who need independent spindle control and variable feed speed to handle a wider range of section sizes and species

    Key specification considerations

    Spindle Configuration
    5, 6, 7, or 8 spindles
    More spindles allow additional profile passes in a single run, reducing the need for multiple passes or secondary operations — worth discussing against your profile complexity before specifying.
    Feed Speed
    6–40 m/min (variable)
    Variable feed speed allows you to adjust for different species and section sizes without changing the machine setup, which matters when your production mix changes regularly.
    Working Width
    10–230 mm
    If your maximum section exceeds 230 mm, speak to us about the GL-645 (450 mm capacity) or GL-630 (300 mm capacity) before specifying.
    Total Installed Power
    Varies by spindle count (see full spec)
    This machine requires a three-phase supply; confirm available amperage at your distribution board before ordering.

    SpecificationValueNotes
    Model Variants
    GN-5S23 (5 spindle), GN-6S23 (6 spindle); 7 and 8 spindle configurations also available
    Number of Spindles
    5 to 8 (buyer's choice)
    Each additional spindle adds a working head — useful if your profiles require multiple moulding passes or if you want a dedicated spindle for thicknessing separate from profiling.
    Spindle Adjustment
    Vertically and horizontally adjustable, independent drive per spindle
    Thickness Spindle
    Adjustable independently from the feeder
    Independent thickness adjustment means you can fine-tune the finished dimension without altering your feed settings — useful when working to tight tolerances.
    Spindle Setup
    Mechanical digital readouts on all spindles
    Digital readouts allow repeatable setup when returning to a previous profile, reducing downtime between production runs.
    Feed Unit
    Variable speed; steel and rubber feed wheels under pneumatic pressure
    Short/Narrow Workpiece Handling
    Side front pressure plate on left vertical spindle
    This assists smooth feeding of short or narrow sections that would otherwise chatter or stall — relevant if your production includes smaller mouldings or window components.
    Working Table
    Chromed cast iron; powered roller after last spindle
    Lubrication
    Centralised lubrication system
    Air Pressure Regulation
    Centralised
    Control Layout
    All spindle control levers located at front of machine
    Frame Construction
    Cast iron
    Certification
    CE certified
    CE certification confirms the machine meets European machinery safety directives — a baseline legal requirement for use in the UK and EU.
    Working Width (max)
    230 mm (min 10 mm)
    Working Height (max)
    160 mm (min 7 mm)
    Feed Speed Range
    6–40 m/min (variable via frequency inverter)
    The inverter-driven feed allows smooth stepless adjustment across the full range — no mechanical speed changes needed when switching between species or section sizes.
    Spindle Speed
    6,000 rpm
    Total Installed Power
    Varies by spindle count; individual spindle motors typically 7.5 kW each (confirm with IWM at enquiry stage)
    Confirm three-phase supply and amperage availability at your site before ordering; total draw will depend on the spindle count you specify.
    Machine Dimensions (L × W × H)
    Contact IWM to confirm — varies by spindle configuration
    Allow additional clearance at the infeed and outfeed ends for full-length stock, and overhead clearance for extraction ducting.
    Machine Weight
    Contact IWM to confirm — varies by spindle configuration
    Floor loading capacity should be checked before installation; cast iron construction machines of this class typically exceed 500 kg.
    Extraction Connection
    Contact IWM to confirm connection diameter and quantity
    Noise Level

    Is this the right
    machine for you?

    Choose the Fourside Planer Moulder GN-5S23, GN-6S23 if...

    • Your production is at medium-to-high volume and you need a machine that will hold up to consistent daily use — the cast iron construction is a meaningful step up from lighter fabricated-frame moulders
    • You're running complex profiles or multiple section sizes and want the flexibility of 5 to 8 spindles with independent adjustment on each head
    • Fine surface finish off the machine is important to your process and you want to reduce time spent on downstream sanding or finishing
    • You need repeatable setup across multiple profiles — the mechanical digital readouts on each spindle make returning to a previous setting straightforward

    Consider an alternate model if...

    • Your volume is lower or your profile range is simpler — the Soukup GS-423 or GS-523 may be a more appropriate and cost-effective starting point; talk to us about where the crossover is
    • You need a wider working width than the GN series offers — the GL-645 (450 mm capacity) or GL-630 (300 mm capacity) may be worth considering depending on your maximum section size
    • Your requirement is primarily straightforward four-side planing rather than complex moulding profiles — the Four-Sided Planer Model 180 PSE may be better suited and easier to maintain
    • You are running a smaller joinery workshop with intermittent rather than sustained production — the GH-623 Moulder may better match your throughput and floor space constraints
