一．Application & Market Positioning FAQs

Q1: What shoe styles and production scenarios is AB‑680 intelligent heel and side lasting machine suitable for?

A1: AB‑680 is a practical heel‑and‑side lasting equipment, specially developed to replace traditional manual hand‑pull waist‑upper process. It is cost‑effective and fits mass‑production assembly‑line scenarios. It can process various shoe types including children’s shoes, high‑top shoes, sports shoes and casual shoes. It is widely adopted in medium‑and‑large shoe factories with frequent shoe‑model switching requirements, and supports stable single‑shift or two‑shift high‑intensity continuous production.

Q2: What core pain points of shoe factories can this equipment solve?

A2:Conventional manual hand‑pull waist‑heel lasting heavily depends on skilled workers, with unstable finished‑shoe consistency and high reject rate of defects such as heel wrinkles, “double‑eyelid” heel‑edge folds and poor upper fitting. Long‑time running of old‑style hydraulic heel‑side lasting machines easily causes excessive oil temperature, leading to pressure drift, oil leakage and shortened component service life. AB‑680 adopts low‑temperature constant‑temperature hydraulic system and PLC recipe memory function. It lowers operator skill threshold, shortens shoe‑style change‑over time, stabilizes lasting quality and reduces reject ratio in mass production.
