EPS (Expanded Polystyrene) shape moulding machine is a type of equipment used in the manufacturing process of EPS foam products. EPS foam, also known as Styrofoam, is a lightweight and versatile material widely used for insulation, packaging, and construction applications.
The shape moulding machine is specifically designed to produce various shapes and sizes of EPS foam products, such as blocks, sheets, panels, and custom molded products. It uses steam and pressure to expand and mold the EPS beads into the desired shape.
Here's a general overview of how an EPS shape moulding machine works:
Pre-expansion: The process begins with the pre-expansion of EPS beads. The beads are fed into a pre-expander, where they are exposed to steam and heat. The heat causes the beads to expand and fuse together, forming expanded beads with low density.
Aging: The expanded beads are then transferred to an aging silo, where they are allowed to cool and stabilize for a certain period. This aging process helps to improve the performance and consistency of the EPS foam.
Main features :
1.The rack configuration with high strength improves the useful life of equip- ment by high annealing aging heat treatment,derusting by sandblast,galvani- zed surface and spraying heavy-duty paint on the surface.
2.Adopted with two-part light replaceable guide bushing and wearable self- lubricating copper bushing to resolve the problem of difficulty to replace guide bushing of the equipment and improve the lubricating effect atthe same time .
3.The hydraulic pressure System of the equipment is adopted with the design scheme of high speed and high pressure.The opening&clamping mold speed of conventional pumping unit is 150mm/s and the maximum opening&clamping mold speed of energy-saving machine can reach at 250mm/s.The automatic machine is adopted with clamping mode with two points each in both sides, which can clamp mold preferably to reduce leakage.
4.Technique application of pilot-operated steam valve:the valve is adopted with cylineder actuator of DN 80 to control large-diameter valve with accurate sensi- tive control.The input steam pressure stabilizes in 0.1-0.15Mpa with the error of±0.01Mpa.The heating time of the same type of equipment shortens by 30% and the energy consumption decreases by 25-30% on year -on year basis.
