There are big difference and discrepancy existed between China’s egg tray machine and that from oversea countries.
In terms of egg tray packaging units, there aren’t too much difference. In terms of molding units, rotary molding solution are used for both China and oversea countries. Chinese egg tray machine had also been exported outwards with stable quantity every year.
In terms of drying units, the technique from oversea has more advantages. According to special parameter of the egg tray, temperature and humidity are supervised constantly during the whole drying process by computer engineering, such technique reduces the consumption of fuel and increases the drying efficiency.
In terms of automation, the labor cost is much more higher in oversea regions where the automation technology had been used commonly. In China, apart from low labor cost, various egg tray, egg box products are produced, the automatic production line doesn’t provides much convenience during molding changing and speed adjustment. Therefore, the automation is used partially in molding and drying. For the hot pressing, manual work and semi-automatic is used.
The mold manufacturing is paid with more attention in oversea countries as the final customer requires egg tray with better appearance and precise accuracy. Also as the environmental protection and plant management are taken care of, the waste water treatment section had been utilized commonly and most of the pulping section adopts stainless steel or anti-corrosion material.
