Self-Adjusting Precision Lifter
DME’s Accualign lifter features a multi-axis self-adjustment system that compensates for misalignment.
DME has redesigned its proprietary Accualign lifters created to accommodate undercuts and allow for the successful ejection of parts. With older designs, any flaws in the original manufacture of the tool or plate movement caused by thermal expansion during molding can cause misalignment and put pressure on the lifter, ultimately leading it to bind or even break.
DME says its multi-axis self-adjustment system compensates for misalignment. The 3D movement is accomplished by applying a carbide ball adapter that rides in a hardened shoe. This allows the rod and bar to self-adjust to the correct non-binding position vertically. DME says this design is complemented by a dovetail connection between the rod/bar and the ball adapter to adjust horizontally.
Accualign lifters are available in both imperial or metric dimensions; rod with a guide bushing (and optional keeper key to secure the lift head); or square/rectangle bar with carbide roller guides for support and long life.

Demands to create smaller, lighter parts have made thin-wall molding one of the most sought after capabilities for an injection molder.
A poorly designed profile die—one that does not permit the part to be extruded with the same dimensions from run to run—coupled with a lack of understanding of the extrusion process, is a recipe for scrap generation.
Producing plastics parts with undercuts presents distinct challenges for molders.
