Elastomeric components are toleranced based on the chosen process and in accordance with prevailing international standards. It should be noted that elastomers are flexible and deformable, rendering standards for plastic and metal parts inapplicable.
For drawing preparation, centered tolerances are recommended. Due to the molding process, mold fabrication, and material shrinkage, material savings cannot be achieved through eccentric tolerances.
Techné's technical service prefers to work with client's 3D drawings (centered dimensions) in STEP/STP format for tooling development.
