In the past two years, the lead–acid industry has seen an increase in the demand for absorptive glass-mat (AGM) and enhanced flooded (EFB) batteries. Consequently, new plants have been built to focus primarily on these designs. This development has drawn more attention to the importance and consequent difficulties in the plate-making processes given the requirement to deliver products of higher quality than previously acceptable for flooded batteries. Modern types of lead–acid battery exhibit greater sensitivity towards variations in plate thickness ― AGM designs are more susceptible than EFBs. Obviously, plates that are too thick for the AGM battery container are not acceptable. In addition, even if they fit snugly, reduced battery life and short-circuiting can eventuate. The importance of plate thickness therefore depends on the type of lead–acid battery that is being manufactured. Responding to these challenges, Co-efficient has been engaged in the improvement and automatic application of paste through the development of a new product, namely, the Paste Saver. The presentation introduces case studies that show a doubling of the performance levels achievable with in-line thickness gauging (i.e., a 100% increase in the process capability index, CpK).
Chief Executive Officer
Steve Mate has served as the CEO of Co-efficient since he founded the company in in September 2005. Co-efficient was conceived to meet a real desire within the lead–acid industry to integrate in-line thickness control systems into plate manufacturing. Nowadays, Steve spends most of his time working with customers. In another life, Steve worked as a photonics and application engineer at Intelligent Photonics Control and Nortel Networks.
