Insert moulding · Metal insert moulding

Metal insert moulding.

Anti-vibration mounts, bonded seals, grommets with metal sleeves. Metal insert moulding creates a permanent bond between rubber and metal inside the tool.

The detail

A good bond starts at the metal

Rubber-to-metal bonding depends on the metal surface: clean, roughened where appropriate, and coated with a bonding agent matched to the rubber. Skip a step and the bond is only as strong as the weakest patch.

We manage surface preparation carefully, record which bonding agent batch was used, and pull-test samples from each batch.

The rigid part goes into the tool and silicone is moulded around it, so you get one finished part.

Questions

What people usually ask.

Which rubbers bond to metal?

Most common rubbers, including silicone, bond well with the right agent. We'll recommend a system.

Can you recover metal parts from failed mounts?

Sometimes, if the metal is valuable. We'll assess samples.
