Diffuser part with multiple action mold

This customer required a plastic diffuser for use in its floor ventilation system. Of somewhat complicated design, the diffuser presented several engineering challenges including heavy point load requirements, flame retardant specifications and multiple undercut features at extreme angles.

Multiple Action Molds

Our Challenge

Our Solution

Working from the diffuser's existing design, Melet's engineering team fine-tuned the part for injection molding, ensuring that it maintained it's specifications for strength. We then identified the best specialty engineering resin for the client's flammability and mechanical specifications.

About the Project

Design of the tool provided the biggest challenge, as it required no less than 16 external slide actions and 32 internal multi-angle lifter mechanisms for completion. The mold assembly itself was manufactured entirely in Melet's toolroom relying heavily on our advanced CNC wire EDM technology capabilities.
