Do you know how styrofoam formed? Styrofoam molding machine can process all kinds of bubbles, from this page you will know what EPS shape molding machines are.EPS machine is refers to polystyrene foam manufacturing. Whole set of EPS machine equipment includes presets, sheet and automatic forming machines, cutting machines, recycling granulators and auxiliary equipment.The EPS machine can be divided into intermittent and continuous preset. And
automatic shape molding machine

is divided into SPZ100-200 - A/B series, SPZ100-200 T series, SPZ100-200E energy saving high efficient series, and SPZ100-200 FHS series. They form variety of models, widely used in electric foam packaging, fruit and vegetables foam box, bubble chamber of aquatic products and various packaging products.Method of EPS machine is to put raw material into the material foamed by steam or electric heating.Then foaming material is transported into plastic molding machine and molded products. Finally, product is cut or dried, and EPS machine products are sent to cutting machine or drying system.When using this machine with good grounding protection, check whether screws loose, spindle rotating flexibly, motor and wiring installed correctly.EPS Shape Moulding Machine system adopts multiple heating method, adopts solid and shifting balance valve system, control instrument and control valve parts to complete the cycle, thus making the machine more steam saving. The unstable factors of product quality caused by unstable steam source are solved and the quality is greatly improved. Steam and cooling water valves are imported components, safe operation, stable performance, foam molding machine can operate 2-3 machines.
The working principle of foam molding machine is similar to the principle of syringe, it is by virtue of the thrust of screw, the plastic has been plasticized into the molten state of injection into the mold cavity, after curing and shaping the product process.Injection molding is a cyclic process, one cycle mainly includes: quantitative feeding – melt plasticizing – pressure injection – mold cooling – mold opening and taking. After the product is taken out, the mold is closed again for the next cycle.
EPS Shape Molding Machine can change different Mould to produce different foam products, EPS Mould can be customized, the most common foam vegetable boxes, foam fish boxes, seedling trays, ICF Blocks and So on
The need to reduce energy consumption and CO2 emissions is leading to a boom in building insulation using expanded polystyrene (EPS). Not only in the Northern regions, but also in very hot areas, such as North Africa and the Middle East, the market for the insulation of residential buildings is showing a steady increase. German headquartered company Erlenbach has been offering systems for processing particle foams (EPS and EPP) for over 50 years and has delivered more than 8,000 machine units worldwide. The company also offers a special kind of block mould technology to eliminate the bending of EPS boards.
Faster cycle times with electrically driven shape moulding machines
Erlenbach’s main objective is to provide efficient technology for the processing of particle foam applications. As a supplier of the complete application range (block moulding, shape moulding, pre-expanders, recycling units, cutting lines) the company offers electrically driven shape moulding machines with a lower energy consumption, faster cycle times and higher precision than traditional hydraulic driven machines.
Production of EPS insulation boards is carried out in several stages
The EPS block moulding is the main technology to produce heat insulation boards. The production of an EPS insulation board is carried out in the following stages:
1. Pre-expansion of the EPS raw material to the required density
2. Storing the expanded material
3. Foaming the EPS blocks
4. Post treatment of the foamed EPS block
a) Block pressing
b) Storage of the EPS block for drying and to reduce
the residual stresses
5. Cutting the blocks into insulating boards and packaging
Specially developed “Antibending” avoids the bending of EPS boards
The residual stress in the foamed EPS blocks causes the bending of the cutting sheets. Factors such as a reduction in throughput time, material savings, and increase in production volume are crucial for the EPS board production. Erlenbach has invested a significant amount of resources to develop and verify a new kind of block mould technology. The “EMTower antibending” technology is said to be able to combine all requirements in one new block mould.
Due to high temperatures in the block mould, EPS is not evenly compressible on its entire width, and an optimal density distribution can only be achieved therefore by symmetrical steaming and symmetrical compression. Furthermore the EPS pearls will be converted into an oval form by compression. This compression affects the numbers of cell walls/beads at the same thickness and density of a board. An improvement in thermal conductivity at the same density, which results in material saving for ?–based products up to 10%, can be achieved.
EPS block molding machine also called has two working modes: normal feeding and pressure feeding. The two modes can be switched according to the structure and form of the mold. Can choose automatic, semi-automatic and manual operation mode.

EPS Foam Shape Molding Machine Description
The EPS block molding machine is driven by hydraulic pressure and a fast/slow differential system to ensure precise time saving and stable operation for opening and closing the mold.
EPS foam shape molding machine has two working modes: normal feeding and pressure feeding. The two modes can be switched according to the structure and form of the mold. Can choose automatic, semi-automatic and manual operation mode.
Various heating methods can be selected according to the product form to ensure product quality. The vacuum negative pressure system can ensure low water content, fast forming, and short drying time (or no drying).
By steam heating and air cooling, the eps foam bead becomes a large foam board. The PLC English touch screen is adopted to realize the fully automatic production of various shapes of foam boxes for feeding, heating, air cooling, mold opening, mold closing, and ejection.
● EPS Foam Shape Molding Machine adopts Japan, imported touch screen, full English display, intelligent graphical interface control, realizing man-machine dialogue.
● EPS Foam Shape Molding Machine can be fully automatic and semi-automatic.
● Taiwan AIRTCA hydraulic system runs smoothly, with low noise and large clamping force.
● The vacuum system speeds up the product forming speed, shortens the cooling time, and reduces the moisture content of the product.
● The optimized design is clear and generous, with high strength and high cost performance.
● This EPS Block Molding Machine can perform processes such as heating, cooling, feeding, stripping, etc., to adapt to different EPS products.
● Complete fault detection system and motor protection system to ensure the safe operation of equipment.
