GL-630 Moulder

Gau Jing
A heavy-duty four-sided moulder built around a 300mm working width, designed for structural timber, beams, and large-profile mouldings that push beyond the capacity of standard four-sided planers. If consistent surface finish on wide or irregular section is a priority, this is the machine to discuss.

Typically chosen by

  • Timber frame and structural joinery manufacturers working with oversized section sizes beyond the capacity of standard four-sided planers
  • Workshops producing large-profile mouldings or beam components where vibration-free cutting and surface finish quality are critical
  • High-volume operations that need the option of high-speed feed rates to sustain production throughput on wide-section material

Key specification considerations

Max Working Width
300mm
A 300mm working width accommodates structural beam and glulam sections that would exceed the capacity of standard four-sided planers, which typically top out at 230–260mm.
Spindle Configuration
6 spindles, dynamically balanced with hydraulic outboard bearing support
Hydraulic outboard bearing support on the horizontal spindles stabilises the cutting head under heavy load, which is what keeps surface finish consistent when moulding wide hardwood or structural sections.
Feed Speed
Standard 36 m/min; optional 60 or 80 m/min
The high-speed feed options are significant for volume production — specify at point of order, as they affect feed motor sizing and may influence extraction requirements.
Spindle Speed
6,000 RPM

Spindle Speed

Spindle Balance
Dynamically balanced
Dynamic balancing reduces vibration at the cutting head, which directly improves surface finish quality on wide or structural sections.
Outboard Bearing Support
Hydraulic
Hydraulic outboard bearing support stabilises the spindle under heavy cutting loads — particularly relevant when moulding large-section beams or hardwoods.
Feed Speed (Standard)
6–36 m/min (variable)
Feed Speed (Optional)
60 m/min or 80 m/min
High-speed feed options should be specified at point of order — confirm whether they affect spindle motor sizing or extraction requirements.
Pressure Roller System
Pneumatic, multiple-stage control
Multi-stage pneumatic pressure control maintains consistent hold-down across the full width of the workpiece, which is especially important on wide or irregular-section stock.
Automatic Position Control
Optional (computerised)
Computerised position control reduces manual setup time between profiles and improves repeatability on production runs.
Straight Jointer Device
Optional
Profile Jointer Device
Optional
Motor Power (Total)
Confirm with IWM at point of enquiry — varies by spindle count and high-speed feed option selected
This machine class requires a three-phase supply at significant amperage; verify your incoming supply capacity before specifying.
Electrical Supply
Three-phase — confirm voltage and amperage with IWM at point of enquiry
Confirm three-phase supply availability and amperage capacity at your premises before specifying this machine.
Machine Dimensions (L x W x H)
Confirm with IWM — contact us for the current factory dimension sheet
Allow additional clearance beyond the machine footprint for in-feed, out-feed support, and extraction ducting.
Machine Weight
Confirm with IWM — a machine of this class and construction is likely to be substantial
Floor loading should be assessed by a structural engineer before installation of any heavy-duty wide-section moulder.
Extraction Connection
Confirm with IWM — will depend on spindle configuration and high-speed feed option
Noise Level
Confirm with IWM — acoustic treatment of the installation area may be required depending on working conditions
CE Marking
Available — CE compliance is an option at point of order; confirm requirement when specifying
CE marking confirms the machine meets European machinery safety directives, which is required for lawful use in the UK and EU.

Is this the right
machine for you?

Choose the GL-630 Moulder if...

  • You are working with wide-section or structural timber — beams, glulam, or large-profile mouldings — that exceeds the capacity of standard four-sided planers
  • Surface finish consistency is critical and vibration from heavy cutting passes has been a problem with lighter machines
  • You need high-speed feed options (60 or 80 m/min) to sustain throughput on volume production
  • Your operation would benefit from optional computerised position control to reduce setup time and improve profile repeatability

Consider an alternate model if...

  • Your typical section sizes fall within standard ranges — the GN-5S23 or GN-6S23 four-sided moulder may be a more proportionate and cost-effective choice
  • You are working primarily with smaller hardwood or softwood joinery profiles where the GL-630's capacity would be largely unused — the GH-623 Moulder may be better matched to your throughput
  • You are considering a European-built alternative for particular quality assurance or service support reasons — the Soukup GS-423 or GS-523 or the Four-Sided Planer Model 180 PSE may be worth discussing with us
