What are Foam Extrusions?

Foam machinery refers to the machinery for making polystyrene foam, that is, EPS foam machinery. The complete set of foam machinery and equipment includes a pre-engineer, a sheet forming machine, an automatic forming machine, a cutting machine, a recycling granulator and auxiliary equipment.

Foam machinery

1. Among them, the pre-fired machine is divided into intermittent pre-fired machine and continuous pre-fired machine.

2. There are many types of plate forming machines, which can be roughly divided into single-door plate forming machines, adjustable plate forming machines, translation plate forming machines, vertical plate forming machines, and oyster plate forming machines.

3. Automatic molding machines include SPZ100-200A / B series automatic molding machines, SPZ100-200T series automatic molding machines, SPZ100-200E series energy-saving and high-efficiency automatic molding machines, and SPZ100-200F series automatic molding machines. Manufacturing electrical foam packaging, fruit foam boxes, vegetable foam boxes, aquatic product foam boxes and many other types of packaging products, with a wide range of uses.

4. Foam cutting machine is a device that uses electric heating wire to cut foam products of various shapes. There are A type foam cutting machine, C type foam cutting machine, and two-dimensional and three-dimensional foam cutting machines.

5. Among them, the recycling equipment consists of foam crushing, plasticizing, pumping and pelletizing, which are respectively composed of foam crusher, foam granulator and pelletizer. It is made of foam waste foam into particles so For recycling equipment.

1. Foamed or extruded part. The raw materials are put in, and the raw materials are foamed by steam high temperature or electric heating, etc., to be formed.

2. Molding part. Feed the foamed material into the molding machine to form the product.

3. Cut or dry the product. The product produced by the molding machine is conveyed into a cutting machine or into a drying system.

1. Check whether the screws are loose and whether each spindle is flexible.

2. Install each motor and its circuit correctly. The motor uses a three-phase 380V heating chip with a 220V current.

3. Make good ground protection for each machine.

4. Check whether the main shaft of the test machine is turned correctly.

5. The heating sheet is pre-heated until the barrel shell melts the foam. Note that each time the extruder starts, the raw materials in the upper and lower barrels must be completely dissolved, which is used to rotate the big wheel flexibly. Because the residual raw material of the head dissolves, it is recommended to use a torch to strengthen the preheating of the upper and lower heads.

6, flexibly grasp the length of the draw bar, depending on the temperature and water temperature, cool the draw bar by water about 1.1-1.7M, so that the draw bar is not brittle, and does not stick after cutting.

7. Observe the color and shape of the material, and flexibly grasp the supply and stop of the power supply of each heater.

8. For those with more impurities such as ash and soil, you can add 20 mesh -40 mesh, 1-3 layers of sieve before the sieve to ensure the color and purity of the particles.
