What is EPS block making machine


EPS block making machine is a kind of machine used to produce EPS blocks. EPS blocks are widely used in construction, packaging, insulation and other fields. EPS block making machine is composed of four parts: raw material feeding system, heating and cooling system, molding system and cutting system. Raw material feeding system: This part is mainly responsible for conveying the raw material (expandable polystyrene) to the heating and cooling chamber in a certain proportion.


 Heating and cooling chamber: This part is mainly responsible for heating the raw material to a certain temperature (usually around 150 degrees Celsius), so that the raw material can be fully expanded and then cooled to room temperature. After cooling, the expanded polystyrene will become solidified blocks. Molding system: This part is mainly responsible for molding the heated and cooled expandable polystyrene into blocks of various shapes and sizes according to customer requirements. Cutting system: This part is mainly responsible for cutting the molded EPS block into smaller pieces according to customer requirements.


EPS block making machine is a kind of machine which can make EPS blocks from EPS beads. The machine can make different shapes and sizes of EPS blocks according to your requirements.EPS stands for Expanded Polystyrene, which is a type of plastic that is used in many different applications. The machine works by heating up the EPS material and then shaping it into blocks.





Advantages of EPS block making machine


EPS is short for expanded polystyrene. It is a lightweight, rigid foam that is used in a variety of applications, including packaging and construction. EPS block making machines are used to produce EPS blocks, which are then used in the construction of buildings and homes. EPS blocks are made by expanding polystyrene beads with steam. The beads expand and harden to form blocks. There are several advantages to using EPS block making machines:


 - EPS blocks are strong and durable. They are resistant to fire, water, and pests.


 - EPS blocks are easy to work with. They can be cut, drilled, and shaped easily. 


- EPS blocks are lightweight and easy to transport. 


- EPS blocks have a high R-value, which means they are good insulators.


EPS block making machine is very popular in the market because of its many advantages. It is very easy to operate and maintain. EPS block making machine can produce high quality blocks with precise dimensions. The machine is also very versatile and can be used to produce a variety of shapes and sizes of blocks.


Production process of EPS block making machine


EPS block making machine is a kind of equipment which can produce EPS blocks with different densities and sizes according to customers’ requirements. The whole production process of EPS block making machine can be divided into three parts, they are pre-expansion, main expansion and cooling.


 1. Pre-expansion: In this stage, the raw material (EPS beads) is added into the pre-expander through the feeder. Then, under the action of stirrer, the raw material is fully mixed with steam and evenly expanded in the pre-expander. The purpose of pre-expansion is to make sure that the raw material is fully expanded and has good roundness, so as to facilitate the main expansion in next stage.


 2. Main expansion: In this stage, the expanded raw material from pre-expansion stage is transported into main expander through pipeline. Under the action of stirrer, it will be further expanded and formed into blocks with required density and size. 


3. Cooling: After main expansion stage, the blocks coming out from main expander are still in high temperature (about 70℃). 


The production process of EPS block making machine is mainly divided into two steps, pre-expansion and molding. Pre-expansion: The raw material (EPS beads) is sent to the pre-expander by the material conveyor, and then pre-expanded and dried in the pre-expander. The pre-expanded beads are sent to the silo by the belt conveyor for temporary storage. Molding: The expanded bead is weighed by a quantitative feeder and sent to a molding machine for molding.
