\u4e00\uff0eApplication & Market Positioning FAQs<\/strong><\/span><\/p>\n<\/div>

Q1: What shoe styles and production scenarios is AB\u2011727A hydraulic automatic heel lasting machine suitable for?<\/span><\/strong><\/p>\n

A1: AB\u2011727A is a practical pure\u2011hydraulic heel\u2011seat lasting machine, without touch\u2011screen intelligent memory function. It applies to shoes with ordinary or soft midsoles, for shoe lasts height below 180\u202fmm. It is widely used for mass\u2011production of children\u2019s shoes, sports shoes, ladies\u2019 shoes and boots. It is suitable for medium and small shoe factories, sample workshops and production\u2011line stations, adapting to single\u2011shift or medium\u2011intensity two\u2011shift continuous production.<\/p>\n<\/div>

Q2: What core pain points of shoe factories can this equipment solve?<\/span><\/strong><\/p>\n

A2:Traditional manual heel\u2011lasting heavily depends on skilled workers, bringing unstable heel forming quality. Common defects include uneven heel flatness and folded heel\u2011edge. Many low\u2011end hydraulic heel machines have complicated height adjustment and poor positioning repeatability. AB\u2011727A adopts gear\u2011rack\u2011ratchet adjustment structure, supporting precise micro\u2011adjustment of lasting height. It is equipped with supporter two\u2011stage ascending pressing plus wiper heating device, improving heel flatness, lowering operator skill threshold and reducing reject rate of heel\u2011position defects.<\/p>\n<\/div>

    Q4: What are the five\u2011group core special\u2011skill functions of AB\u2011727A?<\/span><\/strong><\/p>\n

    A4:<\/p>\n

      \n
    1. Lasting\u2011height micro\u2011adjustment device<\/strong>: Realize fine tuning for supporter working height, stable positioning for different\u2011height shoe lasts below 180\u202fmm;<\/li>\n
    2. Chain\u2011type forming band mechanism<\/strong>: Chain\u2011wrapped tensioner structure, excellent wrapping performance for various shoe\u2011heel shapes; abundant replaceable wiper & forming\u2011band accessories;<\/li>\n
    3. Gear\u2011rack ratchet\u2011type supporter height adjustment<\/strong>: Fast, reliable adjustment of auxiliary supporter position;<\/li>\n
    4. Supporter two\u2011stage ascending pressing function<\/strong>: Secondary pressure\u2011holding action cooperates with wiper heating (about 70\u2103 for leather \/ PVC uppers), improve heel flatness, prevent corner\u2011fold defects;<\/li>\n
    5. Modular hydraulic\u2011circuit layout<\/strong>: Independent solenoid\u2011valve control for each executing cylinder (supporter forward\u2011backward movement, forming band, wiper, supporter lifting), convenient inspection and component replacement.<\/li>\n<\/ol>\n<\/div>

      Q5:What practical production value do these core functions bring?<\/span><\/strong><\/p>\n

      A5:\u00a0Two\u2011stage ascending pressing plus heating greatly improves heel\u2011surface flatness for leather and PVC\u2011material uppers. Ratchet\u2011type height adjustment shortens shoe\u2011model change\u2011over debugging time. Simple hydraulic\u2011mechanical structure lowers maintenance difficulty, suitable for factories pursuing high\u2011cost\u2011performance heel\u2011lasting equipment.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

      Q7: What power, space and environmental requirements before installation?<\/span><\/strong><\/p>\n

      A7:<\/p>\n

        \n
      1. Power supply: Stable three\u2011phase 380V power source is required; reliable grounding connection must be completed for electrical\u2011safety protection; professional electrician shall verify motor rotation direction; reverse two wires if pressure gauge cannot reach 40KG\/CM\u00b2;<\/li>\n
      2. Hydraulic oil: Fill with approx. 50L 68# anti\u2011wear hydraulic oil before commissioning;<\/li>\n
      3. Space: Reserve at least 1.2\u2011meter operating clearance around the machine for operator movement and consumable\u2011part replacement;<\/li>\n
      4. Environment: The workshop shall maintain good ventilation; avoid heavy\u2011dust and high\u2011humidity circumstance to protect hydraulic valve blocks and electrical components;<\/li>\n
      5. Ground: Installation ground shall be flat and solid to bear machine weight, preventing equipment offset induced by long\u2011time vibration.<\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div>

        Q8: What is the complete standardized operating procedure from power\u2011on to mass\u2011production?<\/span><\/strong><\/p>\n

        A8:<\/p>\n

          \n
        1. Pre\u2011startup inspection: Clean anti\u2011rust oil for new\u2011machine commissioning; check power\u2011supply grounding condition; confirm hydraulic\u2011oil level stays within normal scale; test emergency\u2011stop function; check wiper \/ forming\u2011band matching degree with shoe\u2011last heel contour; remove nail debris on supporter surface;<\/li>\n
        2. Power\u2011on: Switch on main power supply; inject lubricant to all lubrication nozzles; adjust lasting\u2011height, timer\u2011sequence parameters; turn on wiper heating for leather \/ PVC uppers, set temperature about 70\u2103;<\/li>\n
        3. Idle test run: Execute multiple empty cycles without shoe last, check for abnormal noise, oil\u2011leakage and cylinder jamming; verify supporter two\u2011stage ascending action;<\/li>\n
        4. Sample debugging: Place shoe last and upper on supporter platform; fine\u2011tune lasting height, supporter travel and timer parameters; produce test\u2011sample piece until heel\u2011lasting flatness meets factory\u2011internal\u2011quality standards;<\/li>\n
        5. Formal mass\u2011production: Launch batch production; operators conduct random\u2011sampling inspection focusing on heel flatness and edge fitting; Do not pull nails out on the machine, to prevent nails dropping into hydraulic cylinder and causing oil\u2011leakage;<\/strong><\/li>\n
        6. Shift\u2011end shutdown: Clean nail debris and glue residues on mechanical surfaces; turn off heating function firstly, then stop main motor; cut off total power supply for long\u2011time off\u2011duty.<\/li>\n<\/ol>\n<\/div><\/div><\/div><\/div><\/div>
