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

- Q:What mechanical products do you use to make this plastic product?! The more detailed, the better!
- I'm not sure about the mold design. You can find a device and ask for advice. Generally, they will be responsible for design and training
- Q:Such as "computer embroidery processes" - Programming - sample preparation, shipment packing production computer
- Process flow of plastic products1. Preparation before moldingA, grain preheating and drying: if the grain is affected with damp, it should be dried;B, insert preheating: in order to reduce the gap between the cooling shrinkage value of metal and plastic, the larger metal insert should be preheated.C, barrel cleaning: when changing the product, changing the raw materials, cleaning cylinder is required.2, injection molding process feeding - plasticizing - injection - holding pressure - cooling - die opening piecesA, feeding: each feeding should be quantitative, in order to ensure uniform plasticization;B and plasticization: the grains are heated to a molten state in a barrel;C and injection: the injection molding machine uses a screw to inject molten plastic into the mold cavity;D, keep pressure: after the mold is finished, maintain the pressure for a certain time;E and cooling: keep cool for a certain time in the mold cavity;F, mold opening parts: mold open, take out the product.3, plastic parts after treatment: plastic parts after treatment:A, remove the fly edge, material handle.B, inspection and packing.
- Q:ABS plastic processing flow
- ManufacturabilityABS is an amorphous polymer with no apparent melting point. Because of its grades, grades, in the injection molding process should be based on the different grades to formulate the appropriate process parameters, generally in 160X: above, 270C can be formed below. Because the temperature is too high, there is a tendency to destroy the rubbery phase in ABS and begin to decompose over ZTOC. In the process of molding, ABS has better thermal stability, wider range of choice, and it is difficult to degrade or decompose. Moreover, ABS melt viscosity is moderate, its fluidity is better than the polyvinyl chloride, the polycarbonate and so on, moreover, the melt cooling solidification speed is relatively quick, generally in 5 ~ 15S can be cold solid. The mobility of ABS is related to both injection temperature and injection pressure, where the injection pressure is slightly more sensitive. Therefore, in the process of forming hand from the injection pressure to reduce the melt viscosity, improving the filling performance. ABS because of the different components, the performance of different water absorbent and adhesion, the adhesion and absorption of water between 0.2 ~ 0.5% and sometimes up to 0.3 ~ 0.8%, in order to get the products ideal for the drying process, before molding, the moisture content below 0,1%. Otherwise, the surface will appear on the silver bubble,.
- Q:How are the plastic products made of this texture processed?
- FormingKey links in plastic processing. The various forms of plastic (powder, granular, solution or dispersion) made products or blank of desired shape. As many as 30 kinds of molding method. Its choice is mainly determined by the type of plastic (thermoplastic or thermosetting), the starting form, and the shape and size of the product. The commonly used methods for processing thermoplastics are extrusion, injection molding, calendering, blow molding and thermoforming. Thermosetting plastics are generally molded, delivered and molded by injection molding. Lamination, molding and thermoforming are the processes of forming plastics on a flat surface. 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.MachiningThe use of metal and wood processing methods, such as the manufacture of very accurate or small amount of plastic products, can also be used as molding auxiliary processes, such as extrusion section sawing. Because the thermal conductivity of plastic and metal and wood properties of different 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 difference in melt index before and after processing?
- If no additives are added during processing, the melt index is the same as that before processing.
- Q:Where has the machine which sells the plastic processing, wants the true, begs the answer
- There is one in Hebei, TangshanTangshan plastics machinery
- Q:Which kind of plastic is good for machining?
- Generally can be processed, mainly in the tool and process control
- Q:Where are home plastic products, plastic products for daily use, plastic products processing, plastic products, mold
- You are looking for people to give you the processing mold, is it, then you go to the hook online to find ah, above doing this factory a lot
- Q:I don't know how much money it needs! Raw materials are used plastic baskets!
- Production of this material, a basic set of machinery and equipment investment of about 70 thousand, if the amount of large, you can choose to configure the machine at around 200 thousand.
- 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.
