◆
thermoforming machines are recommended which can automatically load and unload with the processes of loading, heating and forming。
◆
For loading, vacuum cups shall pick up the sheet and put them on centering units, which shall ultimately be transported with chains on the guard rails. Since the sheets are moved atop the chains, there is no friction with the chains, no powder shall be produced and, as a result, the sheet will not be scrapped during transportation。
◆
The heaters are composed of quartz radiators which can be adjusted upward and downwards. Far infrared thermo-detector (Raytek) can directly detect the sheets’ temperatures and avoid the influence of ambient temperatures。
◆
At forming, the air for producing bubbles and mould removing are adjusted with pneumatic angle valve and proportioning valve; and high sensitive sensors shall be used to fix the height for forming and ensure the production uniformity。
◆
Mould platforms are raised or lowered with servo motors, the gear has good rack structure, which can accurately be speeded up and positioned, with good mould removal effect and stability, low breakdown rate and easy to maintain。
◆
Motor controlled structure can make the equipment clean, low noise, stable mould table running and good quality。
◆
By incorporating the Germany Siemens HS716 heating cards, energy consumption is reasonably controlled, unit energy consumption for each cabinet liner can be as low as 1.5kwh, resulting in very low production cost。
◆
Product quality is stable and qualified rate can be as high as 97%。
◆
The inner liner thickness can be reduced to 3.0-3.2mm, which can save 20% of raw material cost compared with the sheets of thickness of 3.6-3.8mm。
