Prototek is known for their rapid production rates of precision sheet metal and machined products, but now they are gearing their production techniques to a “sky’s the limit” type of mentality. With Six Sigma in mind, Prototek is planning on improving their sheet metal and machining processes to near perfection.


Six Sigma is a methodology which quantitatively puts each and every process under the microscope to describe statistically how an entire process is performing. By using a Six Sigma calculator, Prototek will be able to study each area to find potential mistakes. To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. A Six Sigma defect is defined as anything outside of customer specifications. The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation reduction through the application of Six Sigma improvement projects. At an average of under 100 opportunities for mistakes for each part, Prototek hopes to achieve near perfection in speed and quality of all sheet metal and machined prototypes and short run productions.


Undergoing Six Sigma qualification is not a simple task, as every opportunity for a defect must be strenuously accounted for and plotted on a pareto diagram to find efficiency and quality enhancing routines to be implemented into every day processes. Each employee will have to understand what it means to achieve Six Sigma, as quality and efficiency has always been Prototek’s niche. Adopting a daunting process like Six Sigma will help solidify Prototek’s commitment to on-time deliveries of high quality parts to the industries they serve, and prove to their customers that they will do what it takes to remain at the top of the precision prototyping industry.
