PMMA GPPS sheet extrusion line

PMMA GPPS sheet extrusion line produced by GWELL The main extruder with bimetallic barrel and screw is specially designed for GPPS PMMA processing (also known as PC), mainly concerned with the efficiency of the exhaust system. The gravimetric high-precision feeder guarantees a constant feed rate synchronized with the gear pump and extruder screw speed.

Description

PMMA GPPS sheet extrusion line introduce

At present, most of the PMMA GPPS sheet extrusion line on the market are single-screw models. The system ensures that the water vapor in the material is fully discharged, and the products produced will not have black spots and yellowing. In addition, China GWELL’s new twin-screw main engine improves the shortcomings of excessive twin-screw shearing in the past, and has better transparency. In terms of output, the new twin-screw of the PMMA GPPS sheet extrusion line has a higher output and is more energy efficient. Ensure the light transmittance and haze of the product. In the field of diffuser panels, after more than ten years of production research and continuous innovation, China Plastic Extruder manufacturer – GWELL machines currently account for more than 80% of the market.

  • The main extruder, with bimetallic barrel and screw, has been specifically designed for GPPS PMMA processing (also PC), mainly in what concerns the efficiency of the venting system. The gravimetric high-precision doses guarantee constant feed rates synchronized with the gear pump and the extruder screw rpm.
  • The co-extruder is extruding a thin layer suitable to protect the sheet against UV rays.
  • It is well known how critical is for the calendaring system to obtain high optical quality sheets: in the 3-roll calender, Gwell engineers have applied the best mechanical and technological solutions. The calendar has three rolls with high gloss finishing on the surface with an internal circulation of pressurized water flow at high temperatures.
  • The total width of the rolls is related to the final net width of the sheet. The standard width for this type of machine is 1220mm, 1650mm, and 2100 mm for net width on a sheet.
  • The calendar geometry can be varied: the upper roll turns around the central roll axis. This particular feature permits to adapt of the calendar to the thicknesses required for the sheet.
  • Roll speed transmission, motor, and reducer controls have been particularly studied to guarantee a rotational movement with absolutely no vibration, an unavoidable factor to get the properties required by the optical quality sheet.
  • The extruded sheet is later protected with polyethylene film and cut to size up to 3000 mm length. An automatic vacuum sucker unit picks up the sheets and stacks them at the side. Different configurations are available upon request.
  • Acrylic board has crystal general transparency, with a light transmittance of more than 92%. Acrylic board colored with dyes has a good color development effect.
  • In addition, acrylic board has excellent weather resistance, high surface hardness, surface gloss and good high temperature resistance.
  • The mechanical cutting, scraping and engraving controlled by microcomputer can not only greatly improve the machining accuracy, but also produce more exquisite patterns and shapes than the traditional way.
  • In addition, acrylic plates can be cut and engraved by laser to make products with strange effects.

PMMA GPPS sheet extrusion line control system

 

  1. PMMA GPPS sheet extrusion line adopts Siemens servo control system and Ethernet transmission technology to achieve high efficiency, high precision, high stability and high security.
  2. HMI man-machine interface, centralized control system, one-screen browsing of the whole system parameters, such as current, pressure, speed, temperature, etc., the parameter information is clear at a glance, and the operation is simpler.
  3. Digital equipment enables our equipment to quickly locate errors and perform remote maintenance when faults occur. Channel-level diagnosis and error analysis can be achieved through HMI, which greatly reduces debugging and production downtime. The highly digital and intelligent system makes debugging easier and maintenance more convenient.
  4. The stable and efficient control system makes the pressure and speed of the equipment more stable so that the equipment can improve its overall performance with ease.
  5. Save energy. The resin does not dry out due to the efficient working of the vented extruder. Material alarm device. When the material level is low, the alarm device will give an alarm.
  6. Perfect after-sales service system, from the installation and commissioning of the whole machine to the production of high-quality plates, and provide life-long technical support.

Application

Acrylic board has excellent weather resistance. It is especially used outdoors, ranking the top of other plastics.
It has good surface hardness and luster, and has great processing plasticity. It can be made into various required shapes and products. It has a wide variety of plates and rich colors (including translucent color plates).
Another feature is that thick plates can still maintain high transparency.

Acrylic board is mainly used for carving, decoration and handicraft production. Extruded board is usually used for advertising signs, light boxes and so on. It is also widely used in instrument parts, automobile lamps, optical lenses, transparent pipes and so on.
In architecture, plexiglass is mainly used in daylighting, roofs, sheds, stairs and indoor wall panels. The application of plexiglass in highway and high-grade road lighting lampshades and automobile lamps is also quite fast.
In terms of sanitary ware, plexiglass can be used to make bathtub, washbasin, dressing table and other products.
