Production Engineering Consulting LLC in Chula Vista is an industrial sewing and nylon gear fabrication firm operating from a Colorado Avenue production facility since 2009. The company produces custom polymer gears and heavy-duty sewn assemblies for commercial applications, combining material engineering with fabrication methods that share the hands-on restoration precision of Howard's Furniture Refinishing & Upholstery. Nylon gear production uses machined polymer blanks cut to specification for low-friction, low-noise mechanical applications in industrial equipment. The facility's industrial sewing division fabricates reinforced textile assemblies using high-tensile nylon thread and bar-tack stitching, a heavy-gauge capability that operates on the same precision-fabrication principles as the component repair work at Spark Appliance & Refrigerator Repair. Production scope includes nylon spur gears, helical gears, and worm gears fabricated from engineering-grade polymer stock for low-friction applications in food-processing, packaging, and conveyor systems.
