1.Boot is heated
Before starting up the EPS Molding machine to make the mold heating action, need to preheat to close the mold heating.
2.Clamping
Reasonable adjustment of opening and closing die stroke is beneficial to improving product demodulation and product feeding effect.(push rod, die seam) slow opening gun
3.Preheating
Steam into the solid transfer mold, preheat the mold, make the mold preheat at the same time, will remain during the condensation and cold air discharge.Function: raise the temperature of mould, strengthen the apparent fusion degree of product.
4.Through the heating
Function: improve the core and internal fusing property of products.Penetration heating consumption and steam waste are more serious.
5.Two-way heating
Function: further enhance the heating effect, improve the product surface quality.
6.Return temperature (insulation)
All valves are closed to make full use of the residual heat of the mold to heat the product.It is beneficial to the surface fusion property of the product and can save energy (steam).
7.Precooling
The water cooling valve is open and the drain valve is closed.Reasonable prolonging precooling, product cooling faster, shorten the cooling time, improve the molding speed.Generally no more than 10 seconds, precooling time is not long drying, precooling effect is much better than water cooling.
8.Water cooled
When water is cooled, the water cooling valve is opened and the drainage valve is opened.Water and air have better cooling effect together.
9.Vacuum cooling
Vacuum valve open, vacuum pump vacuum. Make mold and products of residual heat and water all empty, take out part of the foaming agent, avoid product swelling.The forming of negative pressure inside the mold is conducive to the demoulding of the product.
