The main extruder, with bimetallic barrel and screw, has been specifically designed for PC PMMA processing (also PET-G, GPPS), 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: GWELL is a China Plastic Extruder manufacturer， in the 3-roll calendar China Gwell engineers have applied the best mechanical and technological solutions. The lender has three rolls with high gloss finishing on the surface with the 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 the adaptation 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 a size of up to 3000 mm in length. An automatic vacuum sucker unit picks up the sheets and stacks them at the side. GWELL a China Plastic Extruder Supplier, different configurations are available upon request.

Introduction to PC PMMA solid board extrusion line

• Extruder: Special design of screw, temperature control system, ensure good plasticization of rubber and stable extrusion with high output.The casting roller adopts integral machining of the inner runner to ensure the temperature control plus or minus 1 degree and the rolling surface control accuracy plus or minus one wire to ensure the thickness of the casting film.
• Net change and mould: The hydraulic quick-change device ensures the effective screen change process. The hanger-type die adopts a multi-channel design so that the glue is evenly distributed throughout the mould width, and the mould lip gap control is adjustable.
• Three-roll calendar: According to the characteristics of the rubber, flat three-roller, oblique three-roller, or vertical three-roller, three-roller temperature control is independent of each other, and the gap is adjusted freely to ensure the calendering effect.
• Cooling guide roller bracket: Equipped with a corresponding cold guide roller and multiple intense standing fans so that the cooling effect is good. It is also equipped with a trimming device to ensure the quality of the sheet edge.
• Cutting machine: alloy edge, imported bearing, to ensure sheet cutting quality and long-term stable cutting action.
• Rewinder: Using a torque motor and four-axis automatic tension control, the speed, and winding tension can be adjusted to achieve the purpose of sheet winding and leveling.

PC boards are also called polycarbonate boards, and the substrate is polycarbonate (Polycarbonate). PC sheet is an amorphous, odorless, highly transparent colorless, or yellowish thermoplastic engineering plastic. The plastic industry is called a sheet from 0.1 mm thick to 3.0 mm wide. It is a colorless and transparent amorphous thermoplastic material whose name comes from the CO2 group inside it.

The PC Solid Board Extrusion Line is a high-performance machine that is designed to produce high-quality polycarbonate (PC) solid boards. These boards are widely used in applications such as construction, automotive, and electronics due to their excellent transparency, impact resistance, and heat resistance.

Product advantages and features of PC PMMA solid board

1. Impact resistance and flame retardancy

The impact strength of an endurance board is 80 times that of glass, and a solid plate is 200 times that of glass. At the same time, endurance boards can prevent breakage problems during use, installation, and installation. In addition, the most prominent feature of the PC solid board is that it is not like ordinary glass. Breakage occurs to avoid hurting people. The spontaneous ignition temperature of the PC solid board is 630°C. It was tested by the National Fireproof Building Materials Quality Supervision and Inspection Center. The flammability of the board reaches GB (8624-1997 flame retardant B1 grade), which is a flame retardant engineering material.
