Choose a four-side moulder when profile is the product, not the exception

A four-side planer and moulder earns its place when the same profile is run repeatedly – flooring, cladding, skirting, glazing bead, door and window scantlings. The HOLZMANN VS20PRO dresses all four faces of a workpiece in a single pass, replacing the sequence of surface planing, thicknessing and spindle moulding that a joinery shop otherwise spreads across three machines and three separate handlings of every piece. Where profiled linear metres are an occasional job rather than a production line, a planer-thicknesser plus a spindle moulder stays the cheaper and more flexible route.

Capacity: four heads working at once

The VS20PRO carries four planer heads of 120 mm diameter working the bottom, both sides and the top face, so the machine is set once and the timber passes through once. Head diameter matters twice over on a moulder: a larger head accepts deeper profile knives, and it takes a finer cut per revolution at a given feed speed, which is what leaves a surface that needs no sanding before finishing. Confirm the working width and thickness range against the specification for every profile on your list before tooling is ordered.

Power supply: the VS20PRO is a 400 V machine

The VS20PRO draws 17.1 kW from a 400 V three-phase supply, so a four-side moulder is never a machine to run from an ordinary 230 V socket. The incoming supply, cable cross-section and protection have to be sized by an electrician before the machine arrives. A workshop on single-phase supply should treat the supply upgrade as part of the project cost rather than as an afterthought discovered on installation day.

Floor space, foundation and extraction

A 1000 kg cast structure needs a solid, level concrete floor, and the space that really matters on a moulder is not the footprint but the infeed and outfeed runs: allow the length of your longest workpiece in front of the machine and behind it, plus working room on the feed side. Four cutting heads produce chip volume that no small mobile unit will clear, so a ducted extraction system with adequate airflow at every hood belongs in the same project, and the number and diameter of the extraction ports should be confirmed in the quotation.

Tooling is a separate budget line

The moulder is only half of the investment. Profile knives, a head set for each profile, setting gauges and a knife setting or grinding arrangement are ordered against your own drawings, and they are what turn the VS20PRO into saleable product. Budget the tooling package alongside the machine and name the profiles you actually sell when the quotation is requested.

What the quotation depends on

The quoted figure for a VS20PRO is driven by configuration rather than by the bare machine: the head and knife package, feed and control options, delivery to your site in Georgia, positioning and commissioning, and operator training. Sending your profile list, timber species and target output with the enquiry gets a specification back that matches the work instead of a generic price.
