Anodizing equipment from the Sandford Processing Corporation should be your first choice when you are looking for a quality finish to your aluminum parts. The Sanford Low Voltage System provides the precise levels of current needed for greatest efficiency at various stages of each of the Process variations (Sanford + Plus and Sanford – Quantum). Several control units are generally used for the Process: Remote control box and Diagnostic unit, for discovering and identifying trouble, Transformer units, Saturable Core Reactor units and a Safety box.

“Anodizing equipment from Sanford combined with the proper process leads to the best finish”.
Sanford Processing offers three (3) Process options to cover the broadest possible range of hardcoating applications for prospective users of hardcoating:
*SANFORD CLASSIC PROCESS™ ; using Sanford's additive "Sanfran" conventional high voltage hard anodizing can be successfully performed on all alloys.
*SANFORD + PLUS PROCESS™ uses a patented low voltage D.C. current, with superimposed A.C. current to provide state-of-the-art hard anodized finishes of extraordinary thickness;
*SANFORD QUANTUM PROCESS™ is a room temperature process that uses a low voltage D.C. current with A.C. current superimposed to hard anodized in any desired color.
ANODIZING EQUIPMENT MAINTENANCE
Operation and routine maintenance of Sanford Processing equipment does not require technical or electrical knowledge or ability. In addition to extensive, practical training of operation and maintenance personnel, licensees receive a comprehensive instruction manual. Each part of the Process equipment is labeled with a specific part number, to identify it for maintenance and replacement. Almost any additional information needed for occasional adjustments and repairs to the equipment can be received by phone or fax conference from Sanford’s representatives.
ABOUT ANODIZING EQUIPMENT AND THE SANFORD PROCESS
The Sanford Process™ is the leading technology in the global hard anodizing market. What is hard anodizing? Developed more than forty years ago, hard anodizing is an electrochemical process that involves placing an aluminum part into an electrolytic bath and applying electrical current through the bath. This process forms an oxide coating (sapphire-hard) on the aluminum part. This oxide coating can be harder than casehardened steel and provide excellent abrasion resistance; it is protective to the aluminum part and can be very durable.
However, a number of factors can affect the quality, durability and density of the coating. This electrochemical process generally creates polarization of the cathode and anode in the electro-chemical process. This normally generates large amounts of oxygen at the anode and hydrogen at the cathode. This polarization fills the pores of the oxide coating and builds resistance to the electrical current. As a result, progressively more voltage has to be applied in order to maintain adequate current densities. These high voltages generate dangerously high temperatures and the potential for catastrophic dissolution of parts being hard anodized.
But the Sanford Process™ solves this electrochemical problem with its unique additive "Sanfran" and its unique applications of power to the aluminum parts, permitting the Sanford Process™ to be the "Finest Hard Anodize Process in the World." |
