Portenga Manufacturing Company has been building quality precision tooling for over 30 years. We take pride in giving our customers great timing and accuracy with every job we do. Portenga Manufacturing will take any 2-D print, 3-D model or existing part and make it a working piece of tooling. High production, short run or one-off patterns can be built with a variety of options to keep cost and timing feasible. Deep, multi-level offset patterns with multiple piece, offset cores or flat back straight core patterns are no match for this experienced shop and keep us driven to produce the best tooling in west Michigan.
