Plastic Modification---ABS/PC；PA/ABS；PPO/PS Compounding Pelletizing line.

1. High output. Twin screw extruder adopts high torque high rotation speed gear box, matched with novel wear-resistance barrel and screw, torque grade 9~11T/A3, the maximum torque grade can reach as high as 15 T/A3.

2. High degree of automation of complete set of production line. Automation includes material storage and conveying, weighing mixing and metering feeding, compounding and pelletizing, automatic packing, finishing the whole process from material to product granule.

3. Multiple equipment large-scale and integrated production. The automatic centralized control system is adopted to share capital construction and environmental protection facilities, effectively reduce various production and operation costs (such as raw material procurement and transportation cost, labor cost, equipment procurement, capital construction cost, etc.)

Process description:

The compounding modification of more than two kinds of resins is mainly aimed at the modification of processing flowability and mechanical properties. The two resins of alloy modification have good compatibility, close processing temperature and complementary characteristics, such as ABS/PC alloy, PPO/PS alloy, PA6/ABS alloy and so on. The raw materials are often premixed, and after uniform mixing, the feeder is fed into the twin-screw extruder, and some formulas require the addition of liquid additives in the middle of the barrel. Then finish the process requirements of compounding dispersion, liquid injection, exhaust/vacuum, etc.

The common pelletizing mode is water strand pelletizing.

The core extruder equipment includes parallel twin screw compounding extruder, reciprocating

compounding kneader, double rotor compounding extruder, SCP high viscosity self cleaning

reactor and large capacity devolatilizer, etc.

At the same time, based on the above main extruder, the design and manufacture of a

complete set of compounding pelletizing production line equipment and compounding

extrusion forming production line equipment can be realized. It is mainly used in the fields

of engineering plastics, modified plastics, wire and cable materials, rubber, packaging,

building medical chemical industry, chemical fiber textile, household appliance and other

industries (see the application case for details).

The existing factory area of the company is 46500 m2 (of which the parent company is

38000m2, and the subsidiary (Nanjing Cenmen) is 8500m2), The core parts and system

of the extruder are designed and manufactured by the company, such as barrel, screw,

gear box, etc. The company has advanced NC machining center, NC screw grinder,

CNC machine tool and other machining equipment. Equipped with Swiss imported

three-coordinate detector and Japanese imported spectral detector and other

advanced inspection and testing equipment. There are complete quality control means

and system from processing to testing, which fully ensure the stability and reliability of

product quality.

The extruders produced by Cenmen company are exported to nearly 40 countries, such as

Germany, Russia, belarus, Japan, Korea, Israel, Ukraine, magiddon, Iran, Thailand, Indonesia,

Brazil, India, Mexico, South Africa, etc.
