O ring molds designed and manufactured in an in-house mold workshop that builds a variety of molds and tools. The tooling is cut so that every o ring produced meets its specified dimensions and each ring in the run comes out uniform in size and quality, which is the difference between a seal that fits and one that has to be sorted on the assembly bench. The molds are built from durable materials so they resist wear through rigorous production cycles, they withstand high molding temperatures without deforming, and they are designed for easy cleaning and minimal upkeep. They are also compatible with various rubber and elastomer materials, so one tool can serve more than one compound.
Uniform ring size across the run removes the sorting step before assembly
Tooling that resists high molding temperature holds cavity dimensions instead of drifting during long runs
Compatibility with several rubber and elastomer materials lets one tool cover multiple compounds
Easy cleaning shortens the changeover between compounds on the press
In-house mold workshop means a cavity correction does not have to be negotiated with an outside toolmaker
Rings that vary in size within a batch have to be sorted before they can be fitted
Tooling that deforms at molding temperature produces out of tolerance rings midway through a run
Molds that are difficult to clean make compound changeovers slow and costly
Tooling tied to one compound blocks a material change without new tooling
Outsourced tooling means every cavity correction goes through a third party

View Details →Yes. There is an in-house mold workshop that designs and manufactures a variety of molds and tools, including o ring molds.
The tooling is designed so that every o ring produced is uniform in size and quality and meets the specified dimensions.
Yes. The molds withstand high molding temperatures without deformation, which is what keeps the cavity in specification through long runs.
The molds are compatible with various rubber and elastomer materials. Tell us which compounds you plan to run so shrinkage is allowed for at design stage.
It is designed for easy cleaning and minimal upkeep, which keeps compound changeovers on the press short.
The ring dimension and tolerance, the compounds to be run, the volume and your press details. Price and lead time are confirmed in writing with the quotation.
Send the drawing, capacity or duty cycle you need and we will come back with the factory match, the build detail and the commercial terms.
