Product Description:

Polystyrene xps foam board/sheet/plate extrusion line


 XPS foamed sheet, also named as Polystyrene Extrusion Plastic Sheet (XPS for short) has a perfect closed-pore alveolate structure. Its density, water absorption, coefficient of heat conducting and the coefficient of steam pervasion are all lower than those of other sheet heat insulating materials and they have the characteristics of strong intensity, light material, airtight, anticorrosion, ageing resistance, low cost, etc. It has been widely used in the fields of heat preservation in the construction industry and the highway, railway, airport, square of the heat preservation and household fitment. It is the generally acknowledged and the best heat insulator in the market at present.

Part One: Quick Details for XPS production line

First, PS solid granules are fed into the primary extruder, heated and melted into viscous fluid, which is injected foaming agent (HFC, carbon dioxide, butane are optional) at the secondary extruder.

Then, under careful controlled heating and pressure, the fluid is forced through a die head where forming and shaping occurs.

Finally, the rigid foam board is cut and trimmed into required dimensions.


PART Two: XPS Production machine

1. Capacity Range: 180 - 500cubic meter per day

2. Thickness: 20 - 100mm

3. Width: 600mm,900mm,1200mm

4. Material: new GPPS, recycled EPS material, recycled PS, GPPS material

5. Vesicant: Freon:F22, F142, F143; CO2; Vacuum

6. Type: Freon type with density from 28 -40kg/m3

             CO2 type with density from 25-33kg/m3

             Vacuum type with density from 26 --31kg/m3

7. XPS prevails in insulation, moisture proof, compresive strength, durability and convenient installation.

8. We also can afford some second-hand working equipments in China market. It's more

   economical and convenient for new investors.

Q:Is there any pollution in the processing of plastic raw materials?
Yes, we have.The plastic itself contains chemicals, in the production process, will react with other substances, produce some odor and so on, so in the production environment must be ventilated, and will produce gas in the process of mechanical production, in production and after the residue, waste water and so on, these are the production of pollution.
Q:Method for producing plastic product
The plastic processing method can be used for rubber processing. In addition, there are liquid monomers or polymers as raw materials such as casting. In these methods, extrusion and injection molding are the most widely used and the most basic molding methods. The mechanical processing of plastic products borrows plastic processing methods such as metal and wood, and makes plastic products of very accurate size or small quantity, and can also be used as the auxiliary process of forming, such as the sawing of extrusion sections. Because the plastic properties and different thermal conductivity of metal and wood, plastics, thermal expansion coefficient, low elastic modulus, when the fixture or tool pressure is too large, easy to cause deformation, cutting heat melting, and easy adhesion on the cutter. Therefore, the plastic processing, the tools used and the corresponding cutting speed, etc., should be adapted to plastic characteristics. The commonly used mechanical processing methods are sawing, cutting, punching, driving, planing, drilling, grinding, polishing, thread processing and so on. In addition, the plastic can also be used laser cutting, punching and welding.
Q:Is there a unit for processing plastic products in Hangzhou, Xiaoshan?
It's easy to come out of the classified trade ads in the newspaper magazines in Hangzhou
Q:What kind of problems do we need to know about the new waste plastics recycling process?
There is, HDPE, LDPE, PP membrane is not clear, PET, PVC bottles are not clear, and so on.When the quality is not up to standard, or the production is low, or the production rate is low, I don't know what to do next. It is not easy to ask for advice, but some of them are still conservative and ask for advice.The above situation is often encountered by the company friends ask questions, of course, vary from person to person, can not be generalized. However, there are still some representativeness. In view of the above problems, we put forward some suggestions for reference only, and we welcome colleagues to discuss together, to help the new line of friends, that is, our future counterparts better development.
Q:How does a lathe process a plastic flowerpot mold?
Therefore, the plastic mold making is not a simple mechanical processing, but needs to be completed from a series of processes, such as drawing design, mechanical processing, fitter polishing, assembly and die testing.
Q:The manufacturing process of plastic products? Who knows?
(4) blow molding: hollow blow molding or hollow molding. Blow molding is resin parison with compressed air pressure in the heat of the closed mold blowing for a method of hollow products, including blow molding and blow molding hollow blown film products two methods. By blowing method can produce film products, all kinds of bottles, cans, pots and containers of children's toys.(5) calender is resin processing is expected to close by various additives (kneading, filter etc.) through the calender of two or more in favor of the opposing calender roll gap is processed into a film or sheet, then from the calender roller peeling off, and then by a molding method for cooling and shaping. Calendering is mainly used in the molding process of PVC resin. It can make films, sheets, plates, artificial leather, floor tiles and other products.(7) foaming material (PVC, PE and PS etc.) adding proper foaming agent to make plastic produce microporous structure. Almost all thermosetting and thermoplastic plastics can be made into foam plastics. According to the pore structure is divided into open celled foams (feel most connected with each other and closed cell foam pores) (most pores are separated from each other), which is mainly composed of manufacturing methods (including chemical foaming, physical foaming and foaming machine) decision. I hope it helps, thank you
Q:I want to open a small plastic particles processing factory,
No cleaning, no cleaning equipment. Then, granulation, granulation machine granulator. There is pollution, smell must be yes, in the living quarters, certainly you can not go on. Remember, there must be three-phase electricity, in less people place production, third, cleaning sewage discharge.There are many details, specifically you learn it yourself. You can sell it. It's sure to make money.
Q:I want to do a medium-sized recycling plastic particle processing plant.
See how you do, I think Pe high profits, Zhejiang Ruian machine good, thirty thousand or so... We are all over there on the machine... I advise you better not do this, dirty, tired... You can't make much money...
Q:I would like to ask you how to produce plastic products, the need for mold, but also the need for large machinery, thank you all
Depending on what you do, different products have different requirements. Plastic products are injection molding, extrusion, injection blowing, extrusion and blowing equipment.
Q:What are the plastic products used in heavy trucks, and how do they form?
5 、 blow molding, blow molding, used in thermoplastics. This is the molten plastic in the mold, under the compressed air pressure, the plastic blow up, close to the mold surface. But, by punching and demoulding products. The production of various types of hollow containers, also can produce thin film, and thin. The land, forming a plurality of heating heating molding thermoplastic. This is the plastic sheet is heated into elastic state, and then subjected to pressure to attach to the mold molding. Multi disc products. Production of dishware, paint, plastic foam molding foaming foot add foaming agent, foaming and foam injection mould making, solidifying products. The utility model is used for making cushioning packages for precise instruments and meters. It is used for molding, molding the thermosetting plastic. This is a powder, flake or granular thermosetting resins and additives, directly close mold in mold, heating, pressurizing, plastic and liquefaction, chemical reaction and curing, cooling after the products. Production of lumber and electrical appliances, machinery parts, 9, casting molding casting molding for jade. The thermosetting plastic molding powder is placed in the material barrel heating to heat plasticizing, pressed into the mold, and the product complete solidification under pressure. Complex products production needs. A metal block 0, casting casting for forming solid thermal plastic. It will plasticized thermosetting plastic injection mould, curing under normal pressure, cooling and demoulding to obtain the products. The production of electronic, electrical and metal insert element
