Three compounds of varying hardness are available, the choice of compound depending on the type of feature to be measured. Metro-FORM is a silicone based polymer that can be injected into blind holes, internal cavities and threaded components. Where conventional techniques would involve the destructive testing of a component, Metro-FORM allows a highly accurate internal representation of the component to be made, leaving the original test piece intact. The moulding can then be easily removed and measured using standard non-contact gauging equipment.
Green is the softest compound, suitable for complex internal features or where the most flexibility is needed to remove the moulding from the component.
Red is the hardest compound, suitable where little manipulation is needed to remove the moulding.
Compounds can be mixed in applications where a range of properties are required.
Each Metro-FORM kit consists of:
Rugged carry case
Two cartridges of each compound type:
2 x ZA912 (soft green)
2 x ZA914 (orange)
2 x ZA916 (red)
Assorted nozzle types
Micro-funnel set (for small orifices)
Detergent bottle for grease removal
Putty to seal off open channels & create hand-holds
