Fixed vs. Closed Dimensions for Rubber Molds
When manufacturing rubber parts, understanding fixed dimensions (machined cavity spaces) and closed dimensions (where mold halves meet) is crucial for proper mold design. Engineers must consider various factors including shrinkage, tolerances, and flash formation to create parts that meet functional requirements while following industry standard tolerance classifications.
