Product Overview
O-ring moulds designed and manufactured in our own mould workshop, which also makes a variety of other moulds and tools. The mould is engineered so every O-ring produced from it is of uniform size and quality, is built from materials that resist wear through rigorous production cycles, and withstands high moulding temperatures without deforming. It is compatible with a range of rubber and elastomer materials and designed for easy cleaning and minimal upkeep.
Key Benefits
- Every O-ring from the mould is of uniform size and quality
- Withstands high moulding temperatures without deformation
- Compatible with a range of rubber and elastomer materials
- Designed for easy cleaning and minimal maintenance
- Durable under rigorous production cycles
Problems It Solves
- O-rings varying in size between production batches
- Moulds deforming at moulding temperature and losing accuracy
- Tooling that only suits one compound
- Moulds that are slow to clean between compound changes
Where It Is Used
Applications And Buyers
Application Scenarios
- Producing a non standard O-ring cross section in volume
- Tooling for a compound that is not available off the shelf
- Replacing worn tooling that no longer holds size
- Bringing O-ring production in house
Who It Is For
- Seal manufacturers
- Equipment makers producing their own seals
- Companies with a non standard O-ring in a product family
- Buyers who need both the tooling and the parts

- Cavity count for the production quantity
- Tool steel grade and surface treatment
- Venting and flash line arrangement
- Tooling supplied alone or with production
Compared With The Alternatives
| Using standard AS568 tooling | Standard sizes are already tooled and are quicker and cheaper; a dedicated mould is for cross sections and diameters that no standard dash number covers. |
|---|---|
| General rubber moulds | An O-ring mould is a specific case of rubber tooling, where cavity uniformity across the whole tool is what decides whether the seals are interchangeable. |
Use Guide
- Confirm the compound before the mould is cut, since shrinkage differs by material
- Set cavity count from the annual quantity rather than the first order
- Clean the mould at compound changes to avoid contamination
- Measure first articles from several cavities, not just one
Questions
Questions Buyers Ask About This Product
Do you make the moulds in house?
Yes. We have our own mould workshop and design and manufacture a variety of moulds and tools.
Will every cavity produce the same size?
The mould is engineered so every O-ring produced is of uniform size and quality. We recommend measuring first articles from several cavities to confirm.
Can it be used with different compounds?
Yes, the mould is compatible with various rubber and elastomer materials, though shrinkage differs between them.
How many cavities should the mould have?
It depends on your annual quantity. Send it and we will quote alternatives.
Can you run production on the mould as well?
Yes, tooling alone or tooling plus production can both be quoted.
