Custom OEM molded medical silicone rubber parts

Molded medical silicone rubber parts are custom components developed for integration into a particular device. Their geometry, size and color can follow the assembly, while the silicone formulation must be selected for the intended contact and operating conditions. The molded part should be assessed within that device rather than treated as a universally suitable medical component.

Begin with the surfaces that locate the part and the function they serve. A sealing region, hand-contact surface and flexible moving section impose different requirements. Distinguish the dimensions that control those interfaces from areas whose main purpose is appearance or clearance.

Include the device's processing and cleaning conditions when selecting the formulation. Where patient contact or sterilization applies, evaluate the exact material and finished component for that use. These requirements belong to the specified device and cannot be inferred solely from silicone construction.

During assembly development, check the part with the actual mating components and intended fastening conditions. Keep handling contamination controlled and preserve the identity of different formulations or revisions. Inspect for pinching, deformation or incomplete seating before the assembly proceeds. A later change to the silicone compound or mating geometry should be reviewed as a device component change, even when the new part has the same outside color and broadly similar shape.

Material options

Custom silicone or rubber formulation, with dimensions and color adapted to the mating component.

Hardness range

Silicone: 20–80 Shore A; rubber: 30–90 Shore A. Assess the grade against this fit requirement: A sealing region, hand-contact surface and flexible moving section impose different requirements.

Custom profile & fit

Their geometry, size and color can follow the assembly, while the silicone formulation must be selected for the intended contact and operating conditions.

Assembly considerations

Inspect for pinching, deformation or incomplete seating before the assembly proceeds.

Design check

Include the device's processing and cleaning conditions when selecting the formulation.
