epp foam moulding machine

Description

used to mold to different kinds of EPP product.EPP foam material/product is widely used in car parts, such as core material of bumper, anti-collision block, car roof and so on. Also it is used in the package area, such as the package of Electronic products, medical devices, food, etc.
 

1. Structure of machine frame

1. Whole equipment frame is welded by *6Mn(high manganese steel Q**5)
2. we make Zinc spraying layer and spray layer on the surface of whole equipment frame, which guarantees the best capability and long lifetime for anti-corrosion.
3. Frame formwork is made of 4 pcs of guide posts, every post can be independently removed and replaced, so you dont need to make an disassemble of whole equipment.
4. Adding the Balance guiding system on the movable mold, to ensure the parallel degree of movable mold running while loading the weight of movable weight, in order to  ensure the distance between movable mold and fixed mold is equality, so that the thickness and size of identity mode are same.
5. equipment use double independently feeding system, can independently work
6. Full range of security surrounded, to ensure. that workers cant touch with equipment working are and make them safe.

1. pipeline system

1. steam pipeline system: the steam feeding of movable mold use the ways of combined rotary assembly type, which reduce the hose using, to reduce the using cost.

1. Air system: the machine is equipped with air drying degreasing system, to ensure the common using and using life of air element. and all valves in air system use Germany GEMU brand.  
2. Water system: Equipment is equipped with quantitative water cylinder, to not affect the cooling efficient of equipment when the pressure of plant water system is too low.
3. Vacuum system: having separated-working high efficient cooling system, working Negative pressure can reach to be *7bar.

1. Control system

1. PLC and touch screen all use Siemens brand.
2. The controlling of steam pipeline valve all use Germany COSYS electro pneumatic digital proportional valve(with Tape positioning controller),use all Digital Proportional Pulse flowing control, pulse feeding, pulse heating.
3. parameters setting is easier, which improve production efficiency and reduce energy consumption
4. when the safe system having fault and safe door is open, the single safety control circuit will cut the PLC output power and working power of AC contactor, so the machine cant run, which ensure the safety of maintenance personnel.

1. Other advantages

1. Whole equipment frame is welded by *6Mn(high manganese steel Q**5)
2. With more large-diameter inlet steam pipes, to achieves evenly heating.
3. Special mold-locking Structure, to ensure enough mold-locking force.
4. There is an balance guiding bar in the movable mold chamber so that it can locate the position of open/close the mold, to ensure the accuracy of mold seam.
5. Set an high efficient condenser as an independent vacuum cooling system.
6. Equipment control system use full digital proportional control, having an precise control of production energy consumption.
7. Using big diameter valve can offer enough supplying capacity in an instant, to short the molding cycle time.
8. Steam room use special Thermal insulation material; realize the insulation, heat insulation of mold cavity.
