Mold designers face a challenge when determining how to best eject a part with undercuts. A lifter is often the preferred solution but there is always an element of the unknown. Thermal expansions of the mold plates or any misalignment of the tool either during manufacturing or through the tool’s lifecycle can result in plate movement placing pressure on the lifter causing the lifter to bind or possibly even break. With its unique multi-axis self- aligning capabilities, the new DME Accualign Lifter solves this problem providing the mold design with more flexibility and peace of mind. These lifters have been designed and engineered to encompass most undercut applications with the use of off-the-shelf components. The Accualign Lifter is available in round rod with a guide bushing (and optional keeper key to secure the lift head) or a square/rectangle bar with roller guides, for support.
