A1: It is used for hot & cold heel shaping of men’s, women’s and sports shoes, especially suitable for inner & outer fold forming of hot melt adhesive heel counters.

Q2: What is the stable 8-hour output of ACH-720B-2C2H?

A2: The dual hot & dual cold station design supports a capacity of 1200 pairs per 8-hour shift, matching small and medium-volume shoe factories.

二. Hot & Cold Mold Core Design FAQs

Q3: What is the advantage of integrated airbag cold outer mold?

A3:The cold mold adopts one-piece airbag structure:

Q4: What material is used for hot molds and what are its strengths?

A4:Hot outer molds are made of industrial eco-friendly silicone: fast temperature rise, stable constant temperature, high forming efficiency, wear-resistant and long service life.

三. Claw & Positioning System FAQs

Q5:What adjustment range does the clamping claw system support?

A5: Independent multi-directional full-range adjustable clamping jaws, can be finely tuned front/back/left/right/up/down according to different heel sizes, making uppers closely attach to shoe lasts and eliminate heel wrinkling defects.

Q6: What’s the function of three-axis red LED positioning lamp?

A6:Wide-angle adjustable sensor positioning lamp, accurately locks heel placement position for all shoe types to avoid offset shaping and unqualified products.

Q7: What material are all adjustable fixtures made of?

A7:Full set of clamps adopt stainless steel + aluminum alloy composite material, sturdy, rust-proof and abrasion resistant for long workshop use.

四.Refrigeration & Cold Mold Structure FAQs

Q8: What cooling configuration does this machine adopt?

A8:Equipped with imported energy-saving compressor and environmental refrigerant, it can quickly cool down to -15°C with even cold distribution and stable long-running performance.

Q9: Why are cold molds designed with 30° adjustable tilt?

A9: Operators can adjust the tilt angle based on shoe lasts or operation habits, easier to load and unload uppers and prevent slipping during cold pressing.

五.PLC Touch Control FAQs

Q10: Can each station set parameters independently?

A10: Yes. The bilingual PLC touch screen supports separate setting of heating temperature, cold holding time and function switches for every hot/cold station, adjustable for leather, fabric and hot melt materials.

六.Customization FAQs

Q11: Can extra functional modules be added on this machine?

A11: Yes. Optional expansion modules including single hot mold, dual hot mold and four activation units can be installed according to customer production demands before order confirmation.
