    Q6: What is the overall structure and drive system configuration of the RB-A12 press?<\/span><\/span><\/strong><\/p>\n

    A6:The machine adopts a frame structure with strong rigidity and high-pressure resistance. The drive system uses a\u00a0<\/span>high and low pressure dual-pump parallel design<\/span><\/strong>, driven by a 20HP high-power motor. The low-pressure pump provides large flow for fast clamping, while the high-pressure pump pressurizes to the set value, ensuring both fast clamping speed and stable molding pressure. The main motor brand is Siemens.<\/span><\/p>\n<\/div>

    Q7: What is the heat source system and temperature control method of the RB-A12 press?<\/span><\/span><\/strong><\/p>\n

    A7:The equipment uses\u00a0<\/span>heat transfer oil circulation heating<\/span><\/strong>. An electric heating tube heats the thermal oil, and a circulating pump delivers the hot oil to the hot plates for uniform and stable mold heating. The temperature control system is precisely regulated by a PLC with a K-Type thermocouple, ensuring constant vulcanization temperature and effectively reducing the sole forming defect rate.<\/span><\/p>\n<\/div>

    Q8: What brands of core hydraulic components are used in the RB-A12 press?<\/span><\/span><\/strong><\/p>\n

    \u56db.Standard Operation Process<\/strong><\/span><\/p>\n<\/div>

    Q9: What is the standard working process of the ASFROM RB-A12 press?<\/span><\/span><\/strong><\/p>\n

    A9:The operation process is divided into 4 core stages:<\/span><\/p>\n

      \n
    1. \n

      Clamping & Pressurization<\/span><\/strong>: Low-pressure large flow drives the piston up for clamping. After clamping, low pressure releases, the high-pressure pump pressurizes to the set value (commonly 150kg), the motor stops, and the PLC starts vulcanization timing.<\/span><\/p>\n<\/li>\n

    2. \n

      Pressure Holding & Vulcanization<\/span><\/strong>: During timing, if the pressure drops 10% below the set value, the system automatically activates pressure compensation to ensure stable product quality.<\/span><\/p>\n<\/li>\n

    3. \n

      Opening & Descending<\/span><\/strong>: After timing ends, a signal triggers the descending valve. Oil pressure and flow return to the tank, and the piston descends rapidly (540mm\/3 sec).<\/span><\/p>\n<\/li>\n

    4. \n

      Mold Loading\/Unloading<\/span><\/strong>: A hydraulic motor drives an in-line gear to move the mold in and out. During retraction, the arc-shaped rail lifts the mold cover 90\u00b0 for safe material removal and loading.<\/span><\/p>\n<\/li>\n<\/ol>\n<\/div>

      Q10: \u00a0How does the RB-A12 press achieve automatic pressure compensation? What is its working principle?<\/span><\/span><\/strong><\/p>\n

      A10:The pressure compensation function is based on the\u00a0<\/span>differential pressure principle<\/span><\/strong>. During pressure holding, if the system pressure falls below the set value (e.g., set 150kg, drops to 135kg, i.e., 10% lower), the pressure switch sends a signal to the control system to automatically start the high-pressure pump for instant compensation until the set value is restored. This effectively compensates for pressure drops caused by material overflow or minor leaks, ensuring consistent vulcanization quality for the entire batch of soles.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>

      Q11:What are the core components of the ASFROM RB-A12 press?<\/span><\/span><\/strong><\/p>\n

      A11:The machine mainly consists of the following 8 core systems\/components:<\/span><\/p>\n

        \n
      1. \n

        Frame-type main frame<\/span><\/strong>\u00a0(load-bearing body);<\/span><\/p>\n<\/li>\n

        Hydraulic piping and cooler<\/span><\/strong>\u00a0(including anti-heat hoses, valves).<\/span><\/p>\n<\/li>\n<\/ol>\n<\/div>

        Q12: \u00a0How do the hot plate area and interlayer distance parameters affect production?<\/span><\/span><\/strong><\/p>\n

        A12:The hot plate area is 460mm \u00d7 460mm \u00d7 50mm. The 50mm thickness ensures excellent heat storage and temperature uniformity. The\u00a0<\/span>interlayer distance is 180mm<\/span><\/strong>, which accommodates molds with large lasts or complex structures while also considering operator convenience for loading\/unloading. The 3-layer structure allows operators to vulcanize multiple molds simultaneously in a single cycle, significantly improving output per unit of time.<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>
