TOLERANCE TABLE FOR MOLDED RUBBER PRODUCTS DRAWING DESIGNATION "A2" (PRECISION)
“A2” tolerances are the norm for RT/Dygert custom molded parts, and indicate a precision industrial grade product. Molds must be precision machined and kept in good repair. Measurement methods are generally less complex than those required for “A1” products
