DFM & Moldability Review
Design for Plastic Injection Molding
Injection molding DFM reviews complex undercuts and moving mold features before mold design and steel cutting. Slider and lifter analysis helps define release direction, travel, clearance, shut-off conditions and ejection sequence.
Tooling Engineering Review
Slider & Lifter Mold Construction Review
Slider and lifter mechanisms are reviewed during DFM to confirm undercut release, movement direction, shut-off conditions, insert structure and sufficient space for reliable mold operation.
The review helps identify tooling risks before mold design and steel cutting, especially for parts with side actions, deep undercuts or complex release requirements.
