一．Application & Production Scenario FAQs

Q1: What production stage is this machine used for? What shoes can it process?

A1: This intelligent 4-cold air bag heel shaping machine works before formal heel molding. It uses high-temperature hot air to quickly activate hot melt glue inside shoe counters, suitable for mass production of men’s shoes, women’s shoes, sports shoes and all footwear with hot melt heel liners. Multiple mold specifications are optional to match different shoe last styles.

Q2: What is the biggest output advantage of 4-station design compared with 2-station models like ACH-720-2CH?

A2: Equipped with four independent cold forming stations, one operator can handle four pairs of shoes at the same time. The 8-hour capacity reaches 2500 pairs, far exceeding dual-station equipment, perfectly matching large-scale shoe factories with high daily order volume.

二. Integrated Airbag Cold Mold FAQs

Q3: What are the strengths of the integrated airbag outer cold mold?

A3:

• Only replace inner cold molds when switching shoe styles; the outer airbag component stays unchanged, greatly cutting mold change downtime;
• Omni-directional air wrapping pressure fits heel radian fully without hard mold indentations or partial incomplete shaping;
• Uniform extrusion eliminates heel wrinkling, improves finished shoe appearance yield.

Q4: Is the airbag easy to replace after aging?

A4:The airbag adopts high elastic wear-resistant silicone material. We supply spare airbags at factory cost, and disassembly & replacement only takes a few minutes without dismantling the whole mold frame.

三. Full-Range Adjustable Claw System FAQs

Q5: What adjustment functions does the independent clamping claw system support?

A5:Each group of clamping jaws supports large-range all-direction fine-tuning (front, back, left, right, up, down). Operators adjust clamping tension and position according to heel height and radian, making uppers closely attach to lasts and avoid edge folds during cold setting.

Q6: What material are the clamping fixtures made of?

A6:All adjustable clamps adopt stainless steel + aluminum alloy composite material, high hardness, rust-proof and anti-abrasion, long service life under long-term continuous clamping.

四.-15℃ Rapid Refrigeration System FAQs

Q7: What refrigeration configuration does this machine adopt?

A7:It is fitted with imported energy-saving & eco-friendly compressor matched with environmental refrigerant:

五.30° Adjustable Cold Mold Tilt FAQs

Q8: What refrigeration configuration does this machine adopt?

A8:It is fitted with imported energy-saving & eco-friendly compressor matched with environmental refrigerant:

六.PLC Touch Screen Control FAQs

Q9: Can each station set parameters independently?

A9: Yes. The PLC touch screen allows separate setting of cold mold temperature, forming holding time and function switches for every station based on leather, fabric and hot melt materials.

Q10: Does the control panel support bilingual language switching?

A10: Standard Chinese & English bilingual interface, convenient for overseas factories and foreign operators to operate and debug.

七.Three-Axis Red LED Positioning Lamp FAQs

Q11: What is the function of the three-axis energy-saving red positioning lamp?

A11: It supports wide-angle adjustment with real-time sensor monitoring, accurately locks heel placement position of all shoe types, effectively avoids offset shaping caused by manual misplacing uppers and guarantees consistent finished heel shape.

八. Custom Expansion Module FAQs

Q12: Can I add extra functional modules according to production demands?

A12:Yes. Before order confirmation, customers can flexibly select and install optional expansion modules including single hot mold, dual hot mold and four hot activation units to match diversified production processes.
