Abstract
The HST MWW-50E is a Wood-based Board Universal Testing Machine built on a 50kN four-column, two-ball-screw frame: a 0.001-1000 mm/min crosshead, closed-loop control of force, displacement and deformation, and a standard fixture set of seven grips that covers the classic wood-based panel tests - internal bond, surface glue strength, static bending strength, elastic modulus, screw force, surface bond strength and compression. The software displays the test curve and data results on the computer with editing, superposition, zooming and printing at any time, and the report format is editable for Excel or Word output. It is built for medium density fiberboard (MDF), particleboard, plywood, joinery board, fiberboard and agglutination joinery board, and the sheet states test methods per GB/T 17657-1999 and GB/T 4897-92, with data also available per GB, DIN, ISO, JIS and ASTM according to customer requirements.

What the MWW-50E is for
Wood-based boards are engineered materials, and their quality is declared in a small set of strength numbers: the internal bond that holds the panel together, the surface bond and surface glue that hold a finish or a veneer on, the static bending strength and elastic modulus that declare how the board spans, and the screw force that declares how it takes fixings. The MWW-50E is the machine that measures those numbers.
- The sheet names medium density fiberboard (MDF), particleboard, plywood, joinery board, fiberboard and agglutination joinery board.
- It automatically calculates the planar strength properties - static bending intensity, elastic modulus, surface combination, screw force, bonding strength, hardness and shear performance - with the corresponding fixture selected per customer requirement.
- The machine strictly complies with the GB/T 16491-1996 Electronic Universal Material Testing Machine inspection standard, meets the GB/T 17657-1999 test method for physical and chemical properties of wood-based panel and veneer wood-based panel, and the GB/T 4897-92 test method for particleboard.
- Beyond those methods, the sheet states it can test and provide data per GB, DIN, ISO, JIS and ASTM and other international standards according to customer requirements.
For a board producer or a lab that inspects board lots, the value is simple: the fixtures, the frame and the software arrive as one suite, so the panel test program runs on a single instrument.
One frame, seven fixture sets
The standard accessories list is where the machine earns its "universal" name for board work - seven test grips ship with it, selected according to the customer's sample:
- The internal bond strength fixture (a 10-piece set) for the panel's internal cohesion.
- The surface glue strength fixture (a 6-piece set) and the surface bond strength fixture (a 6-piece set) for the panel surface and its bonded layers.
- The static bending strength fixture (Ø30) for the bending properties of the board.
- The elastic modulus fixtures for the stiffness measurement.
- The screw clamp grip for the screw force test.
- The compression test fixture with a Ø100mm compression plate for the compression direction.
That combination carries the whole suite - a different board property, a different grip, the same frame and the same software underneath.
How a board test is set up and read
- The 450mm test width between the columns takes full board specimens; the max. tensile testing space and the max. compression testing space are both 770mm, with a 1000mm crosshead travel behind them.
- The crosshead runs from 0.001 to 1000 mm/min at ±0.5% of set speed, so a fast compression check and a slow bending run share the same drive.
- The USA high-precision Load Cell reads ±0.5% within the 0.4-100% FS range at 1/500,000 FS resolution, and the built-in measurement control system runs the force, displacement and deformation closed loop over USB to the computer.
- Constant force, constant deformation and constant displacement control are available across 0.5-100% FS - within ±1% of the set value below 10% FS and ±0.1% at 10% FS and above.
- The Delta AC servo drive with the Japan BEITO reducer moves the crosshead; position limit lights mark the upper and lower positions.
- Safety is layered: stroke protection with machine and computer double protection against over-set, force protection by system setting, and the emergency stop device for handling emergencies.
- The four rubber shock-absorbing pads level the frame and reduce vibration during the test.
- The handheld unit controller (320 x 240 LED display) shows load, displacement and speed at arm's reach and handles test start, test stop and zero clearing.
What the software keeps for you
- Full digital control, with digital adjustment of the zero point and gain of load, deformation and displacement.
- Parameter storage, setting and loading, so several test configurations share one load frame.
- Close-loop control with the reference curve shown while the operator adjusts the close-loop parameters.
- Graphic functions: redisplay, amplification, reduction, self-adaptation, lapping of the curves, printing in the appointed range, and test-point coordinates.
- Automatic analysis of the results, multilevel identity management with different functions per identity level, and test data stored as text files in a database with commercial report forms.
- Multi controlling channels: displacement, force, deformation, stress and strain control, plus constant stress and constant strain.
- Multilanguage support - English (standard), Russian, Turkish, Spanish and more - with the language file editable.
- The report: Excel, Word and template test report output, editable to show the test person, test standard, test curve, test max load, your company logo and company name.

Selection guide: where the MWW-50E fits
- Your program is the panel suite - internal bond, surface bond, bending, modulus, screw and compression on MDF, particleboard, plywood or joinery board - and the seven fixture sets keep one frame across the whole suite.
- You need customization: extra wide and/or extra height frames are available, and the power supply system, tensile space, test width and speed are completely customizable.
- In the HST catalog, the wood-based panels testing machine page sits in the Electronic Universal Testing Machine family - the MWW-50E is the board-dedicated member of that line.
- If your lab also runs general-purpose tensile and compression work outside the board range, the Material Tensile Compression Tester is the wider sibling of the same family.
Total cost of ownership
- Power is single phase AC 220V±10% at 50/60Hz - an ordinary lab circuit.
- The 850 x 550 x 1824mm footprint and 420kg weight make it a floor-standing unit that parks on a standard bench position.
- Consumables are the ordinary wear of grips and plates; the standard seven-fixture set means the first tests run out of the box.
- The computer and printer are part of the standard accessories (HP), so no separate data logger or report station is needed.
- The rubber shock-absorbing pads reduce floor vibration during the test, which protects the readings as much as the fixture choice does.
