A rubber grommet mold contains features that form the part, locate the tooling and support the chosen molding process. The exact arrangement depends on the profile, compound and manufacturing method.
Cavity surfaces and cores define the molded geometry. Locating features help align the mold sections. Vents allow trapped gas to escape, while runners and gates distribute compound where required by the process. Overflow provisions and parting surfaces affect excess material and flash control.
Fasteners, handling features and provisions for monitoring or maintenance support operation. Not every mold requires the same components. Review tooling against the approved drawing, shrinkage allowance, cure process and inspection requirements. Trial parts should be checked before production acceptance.
