一．Product Overview & Application

Q1: What shoe styles and materials can this machine process?

A1: It is a premium dual cold & dual hot heel shaping machine equipped with black silicone hot molds and airbag cold molds, designed for high-standard TPU heel counter forming. It fits men’s shoes, women’s shoes, casual shoes and all complex shoe types with strict heel appearance requirements.

二. Core Mechanical Adjustment System FAQs

Q2: What advantages does the full-range adjustable clamping claw have?

A2: Independent multi-directional large-stroke clamping mechanism, which locks uppers at the optimal fixed position, fully meets the positioning demands of special and complicated heel structures.

Q3: How to adjust the pull-down travel of clamps?

A3:The clamping pull-down stroke can be freely set according to shoe lasts; a dedicated rocker provides fine pull-down compensation during operation, simplifying adjustment steps and boosting production efficiency greatly.

三. Interchangeable Airbag & Silicone Mold System FAQs

Q4:What’s the highlight of the dual-purpose mold design?

A4:

• Combines airbag’s full-surface tight wrapping advantage and silicone mold’s high temperature resistance, long service life;
• Silicone hot molds and cold airbags can be quickly interchanged without replacing the whole mold frame;
• Realizes one machine for multiple shoe styles, reduces customer equipment procurement cost

Q5: What convenience does 180° rotatable cold mold bring?

A5:Both inner and outer cold molds support 180° rotation, easier mold disassembly, cleaning and maintenance, more flexible for multi-style mixed production.

四.Exclusive Functional Design FAQs

Q6: What is the sewing line beautification massage function for?

A6:Unique auxiliary massage structure smooths heel stitching lines after cold forming, eliminates uneven thread marks, upgrades finished shoe appearance and product pass rate.

Q7: What’s the function of LED cross positioning lamp?

A7: Provides accurate positioning reference during feeding, avoids heel forming offset caused by manual misplacing uppers, stabilizes product consistency.

五.PLC Intelligent Control & Refrigeration FAQs

Q8: How flexible is the touch screen control?

A8:PLC bilingual touch screen supports independent parameter setting for each cold/hot station: heating temperature, cold holding time and all function switches can be customized for different upper materials.

Q9: Refrigeration system configuration?

A9: Matched with standard 3/8P refrigeration unit, fast uniform cooling, stable long-term continuous forming.
