Product Overview



Product Description


The SHJ series twin-screw extruders hasve screw threads made of high grade steel with a five-axis machining tool to reduce clearance and wear.

This twin screw extruder is equipped with PLC controllers and high-level touch screen panels for manual or automatic operations. The extruder’s operating parameters are input and displayed on the touch panel. Designed by CAD, the closely intermeshed screw elements have excellent self-wiping characteristics, and can be interchanged with each other easily. Besides, twin-screw compounding extruder is installed with the newly designed torque distribution system, high-precision grinding of hardened gear teeth, and imported high-quality key bearings.

Furthermore, the system is capable of remote control. This twin screw extruder can be extensively used in many fields, such as polymer blending, homogeneity, plasticization, filling modification and granulation, engineering polymer and glass fiber reinforcement, master batch, functional parent granule, special material, power coating material and cable material reactive extrusion, degassing and devolatilization, etc.

All SHJ series twin-screw compounding extruders meet or exceed CE and international safety standards. Tianhua can also design an entire twin screw extruder production line to meet customers’ specifications

Thermo-setting electronic packaging material extrusion technology

    With the rapid development of electronic and information techmology, the integration level of integrated circuit improves continually. The requirement for chip manufacturing is better.Packaging plays an increasingly important role in the chip manufacturing. So the electric packing is becoming an independent industry with rapid development and its market demand is
increasing rapidly.
    The electric packaging material includes metal and non-metal. The former is used for spaceflight and navigation. The latter is also called plastic packaging which is becoming dominant because of its low cost and simple process, The epoxy resin plastic is  the optimum which accounted for about 95% of the total material.
    As the processing base of eloctric product and integrated circuit, our country has a rapid demand for epoxy resin packaging material. According to the market demand,TIANHUA Co., Ltd.Combines 50 years of expertise of manufacturing co-rotating Twin-screw
extruder and makes special equipment, like openable barrel Twin-screw extruder,table press, cold brand granulation equipment and etc. Through continuous optimization and development, we have developed series production line which reached 15-1500 kg/h. The
performance of the equipment keeps up with the advanced levels of the same products abroad.
    Compare with the more applied double roller open mill, the openable barrel twin-screw extruder has superior compounding performance, uniform heat transfer, closed continuous production, steady quality, self-clean function and narrow resistance time distribution. It does not need clean the equipment to replace the material with different color. So this kind of extruder adapts to a variety of materials to extrude steadily and continuously. In addition, the equipment can react accompanied with polymerization and chemical combination which is beneficial to new product development.

    SHJ series is the extruding line used for general-purpose polymers processing, it is one of competitive products of TIANHUA. I can be used for compounding, flling, reinforcement, degradation, coloration, grafting,crosslinking etc. lt can also process retardant master batch,filled master batch,master batch, biaxially oriented film, flame retardant sheet, automobile compounding. thermo-plastic elastomer,rubber & plastics blending,etc. It is also has advantages like stable performance,mature technology. flexible operation,wide range of application etc.
    TIANHUA owned thedesign technology of completely self-cleaning screw, with uniformed screw clearance and excellent mixing effects,can process all kinds of polymer. TIANHUA has been used finite element analysis method to simulate the material flow in channel during the design.This can help us to know well of the working conditions and to justify the final performance of processed materials.
    TIANHUA used special design flow channel of barrel,which can ensure the same deformation and pretend unusual deformation under high temperature.The multi-channel design can enhance the heat transfer capacity effectively and improve the accuracy of the temperature control.
   The series of SHJ(H)and SHJ(S) are high performance and super high performance extruding line with wide die, high performance transfer system and screw shafts.SHJ(H),SHJ(S) machines have higher performance with lower price.
