一．Application & Market Positioning FAQs

Q1: What shoe‑making scenarios is AB‑918A wall‑type sole pressing machine suitable for?

A1: AB‑918A is hydraulic wall‑type sole attaching press equipment for shoe factories. It is used for sole‑upper bonding & pressing procedure. It is widely applied for leather shoes, casual shoes, sports‑style footwear. It fits medium‑and‑large shoe‑making assembly‑lines and sample workshops, supports stable single‑shift or two‑shift continuous production. Different shoe‑last sizes can be adapted via simple mechanical adjustment.

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

A2: Conventional pressing equipment often brings problems such as uneven pressing force, poor sole fitting, easy delamination / bubble defects. Some old‑model machines are complicated to adjust when switching shoe styles and highly rely on skilled operators. AB‑918A adopts multi‑cylinder hydraulic driving structure, independent adjustment for pressing‑head, edge‑pressing and clamping‑tightening movements. It reduces operator skill requirement, improves sole‑upper fitting compactness and lowers reject ratio caused by poor pressing effect.

五.Standard Startup & Production Operation SOP FAQs

Q8: What is the complete standardized operating procedure from power‑on to mass‑production?

A8:

1. Pre‑startup inspection: Remove anti‑rust grease; check power‑supply grounding; confirm hydraulic‑oil liquid level; test emergency‑stop button function; lubricate all lubrication nozzles; clean rubber‑block residues;
2. Power‑on: Switch on main power supply; set each timer for action‑duration; select working‑mode via selector switches;
3. Idle test run: Perform multiple empty cycles without shoe workpiece; check for abnormal noise, oil‑leakage and each‑group action coordination;
4. Sample debugging: Place shoe last + assembled shoe on work station; run test pressing; adjust pressure, time and mechanical‑position parameters until pressing quality meets factory internal‑standards;
5. Formal mass‑production: Put shoes in place, trigger dual‑hand start‑buttons to execute pressing cycle; carry out random sampling inspection of finished shoes each shift;
6. Shift‑end shutdown: Clean rubber‑block and station dirt; stop main motor; cut off main power for long‑time stand‑by.

⚠️ Safety warning: Do NOT put hands into the space between shoe box and pressing‑head during machine running. Do NOT set working pressure above 50 kgf/cm².
