GH-623 Moulder

A six-spindle, high-speed four-sider built for sustained production runs in hardwoods and larger section sizes. Where throughput, surface finish, and reduced manual handling matter most, this is the machine most operations step up to.

Typically chosen by

  • Timber and joinery operations running long production runs of profiled or dimensioned material at volume
  • Workshops where labour costs are a pressure point and the priority is reducing manual handling between passes
  • Buyers stepping up from a lighter four-sider who need greater rigidity and feed performance for hardwoods or larger section sizes

Key specification considerations

Working Width
10–230 mm
Covers the majority of UK joinery and dimensional timber sections — confirm your maximum section width before specifying.
Number of Spindles
6
Six spindles allows simultaneous profiling on all four faces in a single pass, which is where the throughput advantage over a four- or five-spindle machine is realised.
Feed Speed
200 / 250 m/min
Variable feed speed via frequency inverter allows the operator to match feed rate to timber species and cutting depth, which matters when switching between softwood runs and dense hardwoods.
Working Height
7–160 mm

Spindle Speed
Contact IWM for confirmation
Spindle speed data is not published in Gau Jing's accessible specification material — speak to us directly and we will obtain the confirmed figure before you specify.
Feed Speed
200 / 250 m/min
Frequency inverter control allows stepless adjustment — useful when moving between timber species or section sizes without stopping the line.
Feed Motor
Contact IWM for confirmation
Gearbox Transmission
Yes
Gearbox-driven feed maintains consistent feed force under load, which reduces the risk of snipe or chatter when cutting heavy sections.
Hydraulic Outboard Bearing Support
Yes (horizontal spindles)
The outboard bearing support reduces spindle deflection during cutting, which is particularly relevant when running full-width profiles or working in dense hardwoods.
Straight Jointer Device
Available as option
Profile Jointer Device
Available as option
Computerised Automatic Position Control
Available as option
Automated spindle positioning reduces setup time between profiles and lowers the skill threshold for changeovers — worth specifying if you run multiple profiles regularly.
Total Motor Power
Contact IWM for confirmation
A six-spindle high-speed machine of this class carries a substantial connected load — confirm three-phase supply capacity and available amperage on site before ordering.
Machine Dimensions (L × W × H)
Contact IWM for confirmation
Allow additional clearance beyond the machine footprint for infeed and outfeed support, extraction ducting connections, and operator access to all spindle positions.
Machine Weight
Contact IWM for confirmation
A machine of this class is likely to exceed 1,000 kg — floor loading should be checked with your building surveyor before installation.
Electrical Supply
Contact IWM for confirmation
Three-phase supply should be assumed for a machine of this output — confirm available amperage and supply configuration with your electrician before ordering.
Noise Level
Contact IWM for confirmation
High-speed moulding operations typically exceed 80 dB — acoustic treatment or hearing protection will very likely be required; confirm the measured figure with us before installation planning.
Extraction Connection
Contact IWM for confirmation
A six-spindle high-speed moulder generates significant chip and dust volume — extraction system capacity and duct sizing must be matched to the machine before commissioning.

Is this the right
machine for you?

Choose the GH-623 Moulder if...

  • You are running consistent, high-volume four-sided work and need a machine built for sustained production rather than occasional use
  • Spindle rigidity and surface finish quality are priorities — particularly if you work in hardwoods or run deep profiles
  • You want the option to add automatic position control to reduce changeover time and operator dependency as your operation grows

Consider an alternate model if...

  • Your working width requirement exceeds 230 mm — the GL-645 handles material up to 450 mm wide and may be the more appropriate specification
  • Your production volumes are lower or your section sizes smaller — the GL-630 Moulder or GN-5S23/GN-6S23 may represent a more proportionate investment
  • You require European manufacture or specific compliance documentation — the Soukup GS-423 or GS-523 may better suit those procurement requirements
