MM 150 Automatic Molding Sprayer

Note: The MM 150 is now sold under the SP-12 name, click here for details.

The High Performance coating capability of the Dubois MM150 automatic sprayer increases production, lowers costs and virtually levels the playing field for small and medium size companies. A throughput speed set at 150 feet per minute will produce a mile of moulding an hour with consistent quality. The chemical resistant chassis, and yellow zinc-plated articulating gun mounts are indicative of the quality that will provide years of dependable service and satisfaction. The 1-hp hazardous location motor is equipped with a variable speed inverter which provides 110v single phase plug-in convenience. The MM150 is designed to accommodate 29” minimum lengths, and 12” maximum widths.

System Components:

THE GUNS

The MM150 is equipped with three of Graco’s newest automatic air-assisted airless spray guns, manifolds and GG5 tips. The automatic guns work in conjunction with an air logic controller, which controls the opening and closing operating times of the spray guns.
The Spray guns are both solvent and waterborne compatible and fully satisfies the California South Coast Air Quality Management Districts HVLP requirements.
Thanks to their simple operation and maintenance, MM150’s guns do not require expert or skilled operators.

PAINT BASKET

The swing out basket provides convenient access for loading 5-gallon containers of coating. The basket then swings back beneath the machine when in use.

THE PUMP

Coating product is fed to the spray guns by means of the dependable Graco 10:1 Severe Duty piston pump. The design provides a 10:1 fluid ratio to compressed air pump supply. It is multi-gun capable and delivers material on demand at operating fluid pressures to 1200 psi. The stainless steel body is chemically compatible with today’s finishing materials and solvents.

TRANSFER EFFICIENCY

Paint transfer efficiencies to 75% or more are common in controlled systems like the MM150. The reason’s are higher volume of atomization air at lower pressures, timely gun triggering, and the most accurate and efficient angle of gun position relative to the part being sprayed.

THE DENIBBER

The oscillating abrasive quick discs are, in just half a revolution, moving 120 mm sideways in one direction and back again in the second half of the revolution. Altogether the travel of the abrasive on the surface is more than 4”. This means that the fibers on the surface will be attacked alternately from the right and left side up to 20 times per second. As a rule, the rpm will do more to the aggressiveness than the grit.

It should be understood that the MM150 denibber is not a sander per se.
You can expect it to:

Brush small fibers off the surface of the wood without creating new ones. This means the wood will look brighter.
Break sharp edges. The edges still look sharp but the color pigments in the stain, sealer, or topcoat will stay on the edges and protect them instead of falling off.
Used as a sealer “sander”, the discs not only smooth the surface but matte the sealer to make the topcoat adhere better.

MOBILITY

Placed in the spraying zone of a functional spray booth, the booth’s face velocity offers sufficient protection against overspray pollution for the operator and the work area as well. The mobility (it’s on wheels) provides roll away storage convenience when not in use.
