\u4e00\uff0eProduct Application FAQs<\/strong><\/span><\/p>\n<\/div>

Q1: What production\u2011process is the AS\u2011775M high\u2011speed chiller machine used for?<\/span><\/strong><\/p>\n

A1:AS\u2011775M is an inline high\u2011speed freeze\u2011setting machine for footwear mass\u2011production lines. It is applicable for rapid cooling and shape\u2011fixing of sports shoes, casual shoes, work boots and other footwear styles. It is especially well\u2011suited for high\u2011grade shoe manufacturing that demands high shaping speed and dimensional precision. After rapid cryogenic treatment, shoes can be de\u2011lasted immediately, shortening last occupation cycle and improving the turnover efficiency of shoe lasts.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

\u4e8c. Core Features & Advantages FAQs<\/strong><\/span><\/p>\n<\/div>

Q2: What are the highlights of its intelligent multi\u2011mode conveying system?<\/span><\/strong><\/p>\n

A2: Equipped with automatic photo\u2011electric eye sensing unit to realize seamless workpiece conveying and reduce manual intervention. Four selectable conveying modes are available: auto photo\u2011eye fast feed, photo\u2011eye feed, manual fast feed and manual feed. Operators can switch modes flexibly to match different production rhythms, which helps boost line throughput.<\/p>\n<\/div>

Q3: What is the performance of its closed refrigeration system?<\/span><\/strong><\/p>\n

A3:It adopts imported French compressors with closed\u2011loop cooling architecture. It features powerful cooling capacity, low energy consumption and environmental\u2011friendly operation. The internal circulating fans distribute cold air evenly inside the cavity, and the minimum achievable temperature can reach \u201120\u2103. Integrated automatic defrost device regularly melts frost accumulated on condenser surfaces, prevents frost buildup from degrading cooling performance and lowers routine maintenance workload.<\/p>\n<\/div>

Q4: What benefits does ultra\u2011fast freeze\u2011setting bring to shoe\u2011making workshops?<\/span><\/strong><\/p>\n

A4:It greatly cuts cooling cycle time. Finished shoes can perform de\u2011last operation right after coming out from chiller. It reduces shoe\u2011last occupancy time significantly, so factories can reuse shoe lasts more frequently and cut the quantity of lasts required for production. Precise temperature control avoids shoe\u2011body deformation and rebound defects, raising finished\u2011product qualification rate and customer satisfaction.<\/p>\n<\/div>

Q5: About operation and comprehensive\u2011cost advantages?<\/span><\/strong><\/p>\n

A5:It supports one\u2011touch operation together with intelligent automatic defrost function, lowering operating difficulty and staff training cost. Combined effect of automated conveying, flexible speed adjustment and high\u2011efficient last reuse shortens overall production cycle, increases daily output and reduces comprehensive manufacturing cost.<\/p>\n<\/div><\/div><\/div><\/div><\/div>

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

A8:<\/p>\n

    \n
  1. Pre\u2011start\u2011up inspection<\/strong>: Check power supply for phase loss risk; inspect conveyor chain condition; test emergency\u2011stop button; confirm no foreign objects inside cooling chamber.<\/li>\n
  2. Power\u2011on & parameter setup<\/strong>: Turn on main power, activate control\u2011panel power switch, start\u2011up switch and run switch. Set target cooling temperature according to shoe\u2011material requirements. Select proper conveying mode among four available options.<\/li>\n
  3. Idle test\u2011run<\/strong>: Run several empty conveying cycles. Check conveyor movement, fan rotation, refrigeration unit status and automatic defrost triggering logic. Observe temperature reading until cavity temperature stabilizes.<\/li>\n
  4. Sample debugging<\/strong>: Feed sample shoes onto conveyor inlet. Evaluate freeze\u2011setting effect, check whether shoe deforms or rebounds after de\u2011lasting. Fine\u2011tune temperature and conveying speed to meet factory internal quality standards.<\/li>\n
  5. Formal mass\u2011production<\/strong>: Continuously feed shoes at machine inlet. Conduct random sampling inspection each shift. Monitor indicator lights on control panel for abnormal alarms.<\/li>\n
  6. Shift\u2011end shutdown<\/strong>: Stop feeding workpieces, wait for all shoes to finish conveying. Shut down refrigeration system first, keep internal\u2011circulation fan running for a period. Cut\u2011off main power afterwards. Clean conveyor and inner\u2011chamber residues; empty water container generated by defrosting.<\/li>\n<\/ol>\n

    \u26a0\ufe0f Safety warning: Do not open chamber access doors during low\u2011temperature refrigeration operation to prevent frost\u2011bite injury. Operators must receive relevant operation training before using this machine.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
