The Neutec® GrainPro™ is an induction-heated grain-making machine ideal for high-production jewelry casting. The GrainPro uses state-of-the-art technology to dependably produce clean casting grain, consistent in size and shape, for jewelry investment castings, alloying and continuous casting. With this machine, you need not plan your schedule around your grain-making capabilities. Whether you are manufacturing tubing or sheet or jewelry pieces, the GrainPro lets you grain what you need—as you need it—while manufacturing operations continue smoothly and efficiently.

• Neutec® GrainPro™ - An Essential Tool: The GrainPro™ is the perfect tool for making grain—either in batch mode (for alloying) or in continuous mode (for recycling scrap or sprues). The GrainPro streamlines manufacturing processes like never before by creating consistent, fast, high-quality grain for:
–investment casters who depend on consistent alloys for every casting cycle.
–continuous casters who must have homogeneous alloyed metal feeding into their casting crucibles.
–alloy makers who create alloys in wholesale batches.

• Fast Graining Rates and Quick Change-Over: The GrainPro™ is extremely productive, re-graining sterling silver at up to .75kg per minute (45kg per hour), and gold alloys take even less time! When used for making alloys, the GrainPro can be changed from one alloy to another in minutes with no danger of one alloy contaminating another.

• Benefits: The exclusive Neutec® technology engineered into this machine gives it the time- and money-saving benefits you've come to expect from Neutec. The benefits you will enjoy from the GrainPro™ include:
–Consistency—produce homogeneous alloy or grain—batch after batch.
–Quality—make the defect-free, optimal-size grain experts always recommend for a better quality cast.
–Productivity—save time and gain efficiency with high speed continuous grain-making.
–Affordability—less expensive than you might think, the GrainPro begins paying for itself from day one.

–Pulsed Power Stirring™ technology ensures homogeneity.
–Patented AutoValve™ crucible provides continuous operation.
–"Empty crucible" technology ensures complete recovery of metal at the last pour.
–Improved grain-making tank allows rapid alloy changeovers.
–Closed-system with nitrogen or argon gas provides an inert atmosphere.
–Neutec® single-billet graphite crucibles scavenge oxygen dissolved in the metal.
–18-turn induction coil provides superior stirring capabilities and is encased in a ceramic potting that makes the coil extremely reliable and helps to protect against electrical shock.
–Thermocouple types: type-K (2,200°F/1,204°C); type-S (2,700°F/1,482°C)
–Machine weight: 900 lbs. (408.2kg)

Please Note:

IMPORTANT: This item is wired for a 220-volt outlet. Because amperage, outlets and plugs vary widely by location, the power cord ends in a pigtail, allowing you have an appropriate plug installed. To protect the operators and the equipment itself, this work must be done by a qualified professional prior to its use. Rio Grande assumes no liability for improper wiring of the plug.
