O-Ring Moulds
An O-ring mould decides whether every ring coming off it is the same.

Rubber Moulds
We have our own mould manufacturing workshop and experienced structural design engineers, so we can independently design and develop rubber moulds rather than pass the work on. That matters because a tool designed by a shop that will never run it optimises for ease of cutting, not for ease of moulding, and every flash and parting line problem afterwards belongs to somebody else.

Why It Wins
Key Benefits
- Mould design and mould manufacture both carried out in our own workshop
- Intricate detail captured accurately so the moulded part matches the specification
- Tools built to withstand repeated production cycles without degrading
- Scalable from small runs to large scale production
- Reduced production cost over the life of the tool
The Brief
Problems It Solves
- Tooling quoted by a shop with no stake in how the tool runs
- Design changes that restart a whole supplier chain
- Flash and parting line problems nobody will own
- A moulded part whose detail is lost because the tool was never designed for it
Audience
Who It Is For
- Equipment builders who need a tool and the parts from one source
- Companies moving a design from prototype into repeatable tooled production
- Buyers whose existing mould maker cannot support moulding problems
- Manufacturers who want to own the tool for use elsewhere
In Service
Application Scenarios
- Automotive seals gaskets and moulded components
- Medical flexible instruments and equipment parts
- Consumer goods including household items and toys
- Construction seals gaskets and insulation components

How We Check
Quality Control
- Part structure reviewed for mouldability before the tool is designed
- Trial moulding run on the finished tool before it is released
- First article samples sent for customer approval
- Tool maintained here where production also runs with us
Made to Order
Customisation Options
- Tool designed from your drawing or reverse engineered from a sample
- Cavity count chosen against your annual volume
- Compression or transfer construction according to the part
- Tool retained here for production or shipped to you as agreed
Honest Comparison
Where This Is the Right Choice and Where It Is Not
Compared With A separate mould maker
A mould maker who never runs the tool has no reason to design out flash or a difficult parting line. We run what we cut.
Compared With Injection tooling
Injection gives the shortest cycles at the highest tooling cost. For modest volumes compression or transfer is usually the better commercial answer.
Compared With Prototype soft tooling
Soft tools are fast and hide the problems production tooling will have. We will say when a soft tool is genuinely enough.
Use Guide
How to Specify and Order This Part
Send the part drawing or a sample before discussing tool cost
State the annual volume so cavity count and tool type can be chosen
Agree tool ownership and storage in writing before work starts
Approve the first article physically, not from photographs
Keep the tool in production use where possible rather than storing it idle

Compression Transfer and Injection Moulding for Rubber Parts
The moulding process decides tooling cost, cycle time and how much detail a part can carry. Choosing it is a commercial decision as much as a technical one.

Why Rubber to Metal Bonded Parts Go Wrong and How to Buy Them
Bushings, mounts and anti vibration parts fail at the bond far more often than in the rubber. Split sourcing is the reason, and it is fixable at the purchase order stage.

Rubber Moulds Questions
Do you design the mould or only cut it?
Both. We have experienced structural design engineers and can independently design and develop rubber moulds.
Which mould types do you build?
Compression moulds for larger simpler parts and transfer moulds for intricate designs and over moulding applications.
Can I take the tool away after production?
Yes, if that is agreed in writing before we start.
Can you build a tool from a sample part?
Yes. We will produce a drawing for your approval before cutting.
How long does tooling take?
It depends on the part and cavity count. We quote a firm tooling lead time with the price.
Do you also run the tool in production?
Yes. Running the tool ourselves is how moulding problems get solved rather than escalated.
