一．Application & Matching FAQs

Q1: What shoe styles is this toe cap molding machine applicable to?

A1: It supports pre-forming for sports shoes, casual shoes, leather shoes, California shoes and outward-valgus flip shoes. It completes hot softening + cold shaping integrated process for shoe toe caps.

Q2: What is the core advantage of dual-cold dual-hot design compared with single station machines?

A2: Two hot stations and two cold stations work simultaneously, greatly boost daily output up to 1500 pairs per 8-hour shift; continuous hot & cold circulation improves shaping consistency and production efficiency.

Q3: Why is it specially suitable for outward flip valgus shoes?

A3:The mold adopts split independent heating structure for the outward bending area:

二.Core System & Feature FAQs

Q4: How does the hot mold steam heating system perform?

A4:Steam heating modules are arranged on both sides of the machine:

Q5: What’s the performance of the closed direct cooling system?

A5:Independent sealed direct refrigeration system:

Q6: How fast can operators replace molds?

A6: Molds are fixed by quick snap buckles, matched with Teflon binding straps and custom shoe lasts (98% dimensional accuracy based on customer lasts). Skilled workers finish disassembly & replacement of one set of molds within 5–6 minutes.

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

A7: Built-in real-time monitoring sensors automatically adjust beam angles in wide range; accurate positioning eliminates offset during upper feeding, ensuring consistent shaping position for every shoe pair.

Q8: What control system is equipped on this machine?

A8: Full PLC centralized control with touch screen operation interface. All heating temperature, cooling time, pressing pressure and delay parameters can be precisely set and adjusted in one panel for simple operation.

IV. Câu hỏi thường gặp về lắp đặt và vận hành thử

Q11: What preparation work is needed before installation?

A11:

• Lay machine on hard, flat concrete ground;
• Kết nối nguồn điện một pha 220V tiêu chuẩn một cách chính xác;
• Sử dụng máy nén khí có áp suất khí ≥6 kg/cm²;
• Fix the machine firmly and wait 30 minutes before test running.

Q12:What is the correct standard startup sequence?

A12:

• Switch on main power, adjust air pressure to 5–6kg/cm² and check lubrication oil of air triple unit;
• Turn on control panel power, refrigeration compressor, left & right hot mold power;
• Mở van hơi và cài đặt thời gian phun nước;
• Set heating temperature for inner & outer molds, configure hot/cold mold pressing holding time;
• Adjust cold mold gap, lifting height and elevation angle according to shoe last size;
• Bắt đầu sản xuất sau khi khuôn nóng đạt đến nhiệt độ đã cài đặt sẵn.

Q13:What is the standard forming operation flow?

A13:

• Place upper on hot mold station, trigger hot pressing to heat & soften upper;
• After hot mold auto lift, transfer softened upper to cold mold positioning plate;
• Step foot switch to lower cold mold cylinder for cooling shaping with preset time;
• Cold mold auto releases once timing ends, take finished toe cap out.

五.Troubleshooting Common Malfunctions FAQs

Q14: Frost accumulates heavily on cold mold heads after long standby, how to handle?

A14: Shut down the refrigeration compressor to melt frost naturally; wait until frost fully clears then restart the machine.

Q15: Can I restart the compressor immediately after shutdown?

A15: Forbidden. The compressor must stay powered off for at least 5 minutes before restarting, otherwise internal components will be damaged by liquid impact.

Q16: Shaping effect is poor or emergency occurs during running, what to do?

A16: Press the dedicated emergency stop button for left hot, right hot, left cold and right cold stations separately. All mold cylinders will retract automatically, then reposition the upper and restart the procedure.

六.Daily Maintenance FAQs

Q17: What daily maintenance items are required?

A17:

• Daily: Drain water from air three-point combination unit and keep lubricant sufficient; clean refrigeration radiator filter to avoid weak cooling and overloaded compressor;
• Hàng tuần: Bơm dầu bôi trơn cho các cánh tay mở rộng của máy;
• Long-term: Keep surrounding air circulation, maintain machine body and electrical components clean without dust accumulation.

七.Customization & After-sales FAQs

Q18: Can the molds and fixtures be customized for different shoe models?

A18: Yes. All cold mold clamps, Teflon tighteners and shoe last molds are customized strictly according to customer shoe samples. The tightener structure can be freely adjusted, disassembled and replaced to match different toe cap radian requirements.

Q19: Do you supply complete English operation documents?

A19: Full English operation manual, spare parts list, electrical schematic drawing, refrigeration & air circuit diagrams are delivered with the machine. Electronic PDF files can be sent in advance via email.

Q20:What safety protection devices are installed?

A20: Independent emergency stop buttons for each station, overheat protection for heating tubes, compressor overload protection, limit switches for cold mold lifting stroke to prevent collision and hand pinching risks.
