Mecelec Design has designed and built a machine that checks for porosity in aluminium castings following machining operations.
A purpose-designed and built conveyor carries the casting from an industrial wash plant to the leak test machine.
The casting is located and lifted into the leak test area of the machine, where open cavities are closed with special/purpose-designed polyurethane seals.
A pressure decay leak test is carried out on the casting using a high precision pressure transducer with a programmable temperature compensation feature that caters for varying component temperatures following the wash process.
A pass mark is applied to the component following successful testing by this fully automatic machine.
