二. Core Equipment Feature FAQs

Q3: How is the top-mounted steam hot mold heating system?

A3:

• Rapid heating, hit 120°C within 15 mins;
• Temperature fluctuation only ±2~5°C, stable for all upper materials;
• Even steam softening makes shoe uppers fit lasts tightly with better elasticity and surface gloss.

Q4: What’s the performance of closed direct cooling system?

A4:Equipped with 3/8HP refrigerator unit:

Q5: Is mold replacement convenient? What’s the matching precision?

A5: Molds are fixed by quick snap buckles, matched with customized shoe lasts & Teflon binding straps with 98% dimensional accuracy. Skilled workers finish one set of mold disassembly & replacement within 5–6 minutes.

Q6: Can the fixture tightener be adjusted for different shoe toes?

A6: Yes. The tightener firmly locks shoe upper edges, helps form ideal toe radian. It supports flexible adjustment, disassembly and replacement for easy maintenance.

Q7: What is the function of three-axis red LED positioning lamp?

A7: Built-in real-time sensors automatically adjust beam angles in wide range, realize zero feeding offset and consistent positioning for every shoe pair.

Q8: What control system does the machine adopt?

A8: Full PLC touch screen centralized control. All heating temperature, cooling time and pressing pressure can be precisely set and adjusted on one panel, simple centralized debugging. It supports Chinese & English bilingual operation interface.

四.Installation & Commissioning FAQs

Q11: What preparation work before machine installation?

A11:

• Place machine on hard, flat concrete ground;
• Connect standard single-phase 220V power correctly;
• Match air compressor with air pressure ≥6kg/cm²;
• Fix machine firmly and wait 30 minutes before test running.

Q12: What is the standard startup operation sequence?

A12:

• Switch on main power, adjust air pressure to 5–6kg/cm² and check lubricant of air three-point unit;
• Turn on control panel power, refrigeration compressor and left & right hot mold power;
• Activate steam valve and set water spray timing;
• Set inner & outer mold temperature, configure hot/cold mold pressing holding time;
• Adjust cold mold gap, lifting height and elevation angle based on shoe lasts;
• Start production after hot molds reach preset temperature.

Q13: Two operation modes are available, what’s the difference?

A13:

• Manual Mode: Step foot switch for 1st down → press button manually for secondary shaping;
• Auto Mode: Step foot switch for 1st down, machine auto executes secondary pressing after delay time.

五.Standard Production Operation Flow FAQs

Q14: What is the full toe forming workflow?

A14:

• Place upper on hot station after hot mold reaches target temp, trigger hot steam pressing to soften upper;
• Hot mold auto lifts up after timing, transfer softened upper to cold mold positioning plate;
• Step foot switch to lower cold cylinder for cooling shaping;
• Cold mold auto releases after cooling timing, take finished toe cap out.

六.Common Malfunction Troubleshooting FAQs

Q15: Thick frost accumulates on cold mold heads after standby, how to solve?

A15: Shut down refrigeration compressor completely to melt frost naturally; restart after frost fully clears.

Q16: Can I restart the compressor right after shutdown?

A16: Forbidden. The compressor must stay powered off for at least 5 minutes before restart, to avoid internal component damage caused by liquid hammer.

Q17: Poor shaping effect or unexpected accident during running, what to do?

A17: Press independent emergency stop button for left hot, right hot, left cold and right cold stations. All mold cylinders retract automatically, reposition upper and restart operation.

七.Regular Daily Maintenance FAQs

Q18: What scheduled maintenance items are required?

A18:

• Daily: Drain water from air three-point combination unit, clean refrigeration radiator filter to prevent poor cooling and compressor overload;
• Weekly: Fill lubricating oil for machine extension arms;
• Long-term: Keep machine surrounding well ventilated, maintain machine body and electrical parts dust-free and clean.

八.Customization & After-sales Document FAQs

Q19: Can molds and fixtures be customized for different shoe samples?

A19: Yes. Cold mold clamps, Teflon tighteners and shoe last molds can be tailor-made according to customer shoe styles to meet various toe shaping demands.

Q20: What supporting documents are provided together with machine?

A20: Complete English operation manual, spare parts list, 3D assembly drawings, electrical schematic, refrigeration circuit and air circuit diagrams are delivered. Electronic PDF files can be sent in advance via email.

九.Safety Protection FAQs

Q21: What safety devices are equipped on this machine?

A21: Independent emergency stop buttons for each station, heating tube overheat protection, compressor overload protection, cold mold stroke limit switches to avoid hand pinching and equipment collision.
