Highlights:1. The heating system adopts real digital control, which features stable heating, easy adjustment and zero-phase switch of electric furnace for the purpose of reducing impacts of voltage shock, in order to meet stringent requirements of more demanding products. 2. The upper and lower mold cylinders have fast and strong exhaust function, which can rapidly and timely match vacuum forming and accurate demolding. 3. The pulling system adopts Omron frequency converter and PLC control, which result in more accurate pulling precision, prevent materials waste, and better adapt to the demand of high-speed and stable production.
