Equipment composition of GPPS Sheet Extrusion Line

Extruder

According to the GPPS Sheet material property , a roots vented single-screw extruder is selected. The screw adopts a special mixing function and a precise temperature control system to ensure stable plasticization and no burning problem happening.

Die Head

The hanger-type die head with elastic lip which is convenient for adjusting the sheet thickness and maintain flow distribution to be uniform, and the thickness of the extruded sheet is adjusted more accurately.

Three-roll Calender

According to the thickness and glossness of the sheet, a 45° inclined three-roller calender is used. The temperature control of the three rollers is independent of each other, the gap between the rollers can be adjusted freely and have hydraulic quick openning system.

Cooling Roller Bracket

Equipped with corresponding water cooling rollers to achieve better cooling effect and avoid the sheet bending. It is also equipped with a trimming device to ensure the fixed width and edge quality of the sheet.

Haul-Off Unit

The haul-off unit provides consistent traction to pull the sheet through the production line. Its synchronized operation with calendar ensures smooth movement and prevents deformation.

Edge Punching Collection Unit

The edge punching unit removes excess material from the sheet’s sides, providing a clean and efficient way to collect wastage materials.

Knife Cutting Machine

The knife cutting unit with top and bottom knife unit and braking unit can reach non-dust custting and be SYNC speed control with Tractor unit. It’s unique technology give the highlights of the lines.

Auto Stacking System

The stacking system organizes finished sheets for easy handling and storage. It ensures efficient stacking without scratching or damaging the surfaces. It can also reach left and right stacking which is easy for workers calculate the quantities of sheets.

GPPS Sheet Production Line Workflow

Material Feeding

Raw materials GPPS pellets are fed into the hopper of the extruder by vacuum loader and hopper dryer. The feeding system ensures precise measurement and continuous supply for uninterrupted production.

Extrusion and Melting

The extruder heats and melts the raw materials while mixing them evenly. The screw rotation ensures homogeneous material flow and prepares it for shaping.

Shaping and Surface Finishing

The melt material is extruded through a die head to form a flat sheet. It is then passed through calender rollers to achieve uniform thickness and the desired surface finish, such as glossy or matte or embossing.

Cooling and Laminating (Film Coating)

The sheet is cooled using water and air both cooling system to stabilize its structure. After cooling, a protective film is laminated onto the surface to prevent scratches during handling.

Cutting and Edge Trimming

The cooled sheet is cut to the desired length using a cutting machine. Simultaneously, excess edges are trimmed to ensure uniformity and precise dimensions.

Automatic stacking

The cut plates are neatly stacked on pallets using automated robots.

Characteristics and applications of GPPS Sheets

Characteristics of GPPS plastic：

GPPS is colorless, odorless, tasteless, shiny, transparent particles. It is light, cheap, has low water absorption, good colorability, dimensional stability, good electrical properties, transparent products, and easy processing.

Application of GPPS plastic：

General-purpose polystyrene can be used in daily necessities, electrical appliances, instrument housings, toys, lamps, household appliances, stationery, cosmetic containers, indoor and outdoor decorations, fruit plates, optical parts (such as prisms, lenses), lens windows and moldings, car lights, telecommunications accessories, electric frequency capacitor films, high-frequency insulation materials, TV containers, waveguides, chemical containers, etc. Suspension polymer resins can be made into foam plastics of different densities, used as insulation, sound insulation, shockproof, floating, packaging materials, cork substitutes, pre-foamed bodies can be used as water filtration media and to prepare lightweight concrete, and low-foamed plastics can be made into synthetic wood for furniture, etc.
