Injection molding process: mold clamping, injection, pressure holding, cooling, mold opening, and product removal.
a.Mold clamping:The mold clamping device is used to open and close the mold to perform the demoulding operation. One method is to use a toggle lever and another method is that opens and closes the mold directly by using a hydraulic cylinder.
b.Injection:The function of injection device is to melt the resin by heating and then injection it into the mold.Spin the screw,and let the resin which put into the hopper stay at the front of the screw.Injection after storing a certain amount of resin.
c.Pressure holding:When the resin flows in the mold, controlled by the moving speed of the screw and after full of resin,will use the pressure to control,when the screw reach a certain position or a certain pressure,the speed control will change to pressure control.
d.Cooling mold opening and product removal:Next,through the cooling process and the demoulding,the brand new product will be pushed out.
2.Application of Plastic tray
a.Used for Pasta:It can be used for the pasta’s drying or packaging.Pictures as below.
Maybe you will ask,does it food grade or is it good for food?The answer is ‘YES’!
Features:The material of our plastic drying tray is 100% new PP(polypropylene) or PE(polyethylene),food grade,non-toxic and tasteless, safe and environmentally friendly, could be cleaned in high temperature, repeated use.
b.Used for Extruders and Sheeters
The sheeters mainly refers to a research on the tablet technology that used in the medical industry. It is a device for manual or automatic continuous production that make the granular into a diameter of no more than 13mm, round, irregular, and text, symbols, and graphic tablets.
Features:It can stand -20°C-120°C, durable with good corrosion resistance to normal kinds of acid and alkali.
So it also can be used for the seafood freezing.
c.Fruit and vegetable’s draining
Features:Rib design with many holes on it, make overall stronger, increase bearing capacity, longer service life.
The hole design make the wet fruit or vegetable dry.
