: Parts naturally deform under minimal force compared to steel or aluminum. Structure of the ISO 20457 Tolerance Groups TOLERANCES

For flatness, ISO 20457 provides standard tolerances based on overall part dimensions: iso 20457 tolerance table pdf

The bridges this gap. It establishes standard tolerance blocks and surface profile criteria within a defined Geometrical Product Specification (GPS) datum framework. It helps stakeholders explicitly delineate between "general tolerances" (applied broadly to non-functional attributes) and "direct tolerances" (assigned to hyper-critical, tight-fit assembly dimensions).

The serves as the definitive international benchmark for specifying dimensional and geometrical tolerances in molded plastic parts . Replacing older localized frameworks like DIN 16901, this standard governs processes like injection molding, compression molding, and rotational molding for non-porous thermoplastics, thermoplastic elastomers, and thermosets. The overall tolerance for a specific feature size

The overall tolerance for a specific feature size depends on two distinct manufacturing factors: dimensions and Tool-Variable (NW) dimensions.

That stance paid off in unexpected ways. A hospital purchasing manager came by, impressed by their documentation and careful QA. Medical device components and precision instruments followed—products where a near-micrometer variance could mean the difference between success and failure. Contracts that required adherence to standards were awarded to shops that could prove they understood them. Ana's shop was one such place.
