Overmold direct attach mold assemblies: NikeRecent Research Landscape

Traditional footwear assembly suffers from adhesive inconsistency and labor-intensive layering, which is mitigated by using conformal films and specialized molds to integrate outsoles directly. This approach reduces manufacturing cycle times and eliminates the need for manual bonding stages.

What technical problems is Nike addressing in Overmold direct attach mold assemblies?

Inconsistent midsole bond strength

(6)evidences

Irregular geometries and material variations during direct attachment cause weak or uneven adhesion between the sole and upper. Eliminating these interface voids ensures structural integrity and reduces manufacturing rejects.

Inconsistent component bonding alignment

(3)evidences

Inconsistent adhesion and structural separation between multi-part outsole layers during assembly. Eliminating delamination ensures structural integrity and durability of complex composite footwear structures.
