Plastic machine(pre-expander) characteristics:

1  This machine applies PLC and touch screen,automatic feeding,electronic weighing,temperature control,material level control to realize automatic production.

2  Electronic weighing system and material level control system assure the density of the foamed material, which make the bead uniform and keep the density tolerance within±2.5%.

3  High precise guiding pressure reducing valve controls the temperature and steam pressure of the closed barrel, ensure the outcome pressure of the valve constant and the inner temperature controled within ±1%,which keeps the foamed material equal and prevents the bead agglomerate because of the bad temperature control.

4  Automatic material charging system improves efficiency and reduces labor intensity.

5  The closed constant pressure foaming barrel has high heating efficiency. It can save more than 50% energy compared to the continuous pre-expander.

6  Hot air drying system to dry the foamed material inside the barrel without fluidized drying bed.

7  Automatic discharging from the pre-extender,which can automatically filter, crush the ball material and transport the foamed material to aging silos.

8  Most of the main components are of world-famous brands,with reliable performance,stable quality,long service life and low maintenance cost.

9  This machine applies automatic discharging system,the high pressure fan facility improves the speed of discharge.

10         The computer has memory function, which can record all information such as brands, specifications, expanding foam techniques and parameters of EPS material manufacturers. When customers want to use the materials that ever been used before just press the touch screen of computer to quickly go back to the original technique.

This machine is applicable in plateau oxygen depletion area,the production efficiency of continuous pre-expander machine is quite low under such circumstance.

plastic machine(block molding machine) characteristics:

1This machine applies PLC controller and touch screen control system to finish the autocycle process of opening-closing mould, feeding, heating, heat preservation, cooling, demoulding and releasing.

2This machine is welded from high quality square profile steel and steel plate, which is subjected to heat treatment to ensure the machine  has no deformation,and has high durability after being assembled.

3This machine applies unique and advanced EPS heat penetration process,which make high quality plates whose six faces and interior are the same perfect.It also reaches remarkable energy saving effect.

4Advanced EPS heat penetration technique,reasonable pipeline system and unique design construction, which improve productivity,and make this machine leading in domestic EPS industry.

5Most of the main components are of world-famous brands,with reliable performance,stable quality,long service life and low maintenance cost.

6This machine applies hydraulic pressure transmission, hydraulic ingot stripping,which makes steady running and tight locking.

7High production efficiency.The production cycle of each plate is 4-8min.Automatic pneumatic charging shorten the production time.

8This machine applies high-efficient vacuum system and cooling device to improve moulding speed and reduce the moisture content. Vacuum supported machine is high efficient for making high-density thick plate.

Main features:
  1. Use PLC programmable controller and touch screen to finish the autocycle process of opening-closing mold, feeding, heating, heat preservation, cooling, demolding and releasing.
2. According to different products wanted, choose different feeding methods such as common, pressure and vacuum to ensure feeding speed and uniformility.
3. Hydraulic system used in the machine can save 30% energy. Its operation and locking mold are used by the main and auxiliary cylinder respectively.
4. Use digital encoder to control the travel distance of operation and locking mold, ensure the uniformility of each feeding.
5. Balance valve of the machine, used in heating, ensure the same steam pressure and temperature during each mold.
6. Vacuum system, mainly including vacuum storage tank, vacuum cooling tank, and high water-cycle vacuum pump, ensure fast molding, uniform cementing and low moisture content.
7. For production techinical memory and quantity statistic, operator can find and set the different foam parameter by themselves. 

We can provide vacuum and cooling tank according to different size of products

Usage:
1.The machine is used to make PP,PE and PS sheet , which are used to produce drinking cups, ice-cream cups, yogurt cups,packing boxes and so on plastic products .

2.This machine is with extruder ,calender ,winder ,and electric control console.The screw and the cylinder are made of high quality alloy steel (38CrMoAlA)with optimum hardness,strong corrosion resistance and long service lifetime after nitrogen treatment. The flow channel in die head is of coat-hanger design and it ensures the even thickness and the smooth surface of the sheets. The circular wate inside the calender brings perfect cooling Effect,mesh changer and the cylinder are separately controlled.
