On Nov 3rd - 5th, 2021, China Plastic Sustainable Development Exhibition 2021 was held in the Nanjing International Expo Center. With the theme of ‘environmental ecologicalization and sustainable development of plastics’, China Plastics sustainable development exhibition 2021 displayed new green materials, degradable materials, plastic products, energy-saving and eco-friendly plastic equipment , recycling equipment and sustainable development achievements to further strengthen a series of policies for the control of plastic pollution, actively promote new products and technologies that are recyclable, degradable, low-carbon, energy-saving and environment-friendly and accelerate the high-quality development of China's plastics industry.

With 12000 square meters exhibition area, it gathered many industry professionals. As one of  them in the field of China's twin screw extruder, TENGDA Machinery has been committed to product development and manufacturing. After more than ten years of precision research and innovation, we have formed a complete set of fully automatic polymer processing production lines based on twin-screw extruders, as well as independent production of high-end key parts, providing users with cost-effective equipment and perfect after-sales service.

At this China Plastic Sustainable Development Exhibition, what models did TENGDA Machinery focus on? TENGDA will show you.

The main one is 3D Printing Filament Extruding Production Line, which is typically used for PVA water soluble 3D printing filament and TPU/TPR/ABS/PLA 3D Printing Filament. With stable extrusion and high precision , this production line has good performance. The water sink can be adjusted three-dimensionally. Lines adopt servo control, which are neat and beautiful. The advanced gas shaft is used to fix, and the loading and unloading plates are simple.

Speaking of components with more detail, they are also very outstanding.

1.Screw elements


(1)Material is W6Mo5Cr4V2 (high speed tool steel) with the best wear resistance, the whole adopts vacuum quenching treatment, hardness is 60 ~ 62HRC.

(2)Designed by the building block principle, and the screw element and the screw shaft are connected by an involute spline, and the screw combination can be adjusted according to the process requirements.

(3)The screw elements are all made by CNC machining center, with good identity and strong process repeat-ability,which is benefit for changing.

2. Twin-screw Barrel


(1)Use bimetal wear-resistant and corrosion-resistant material

(2)The base material is 45# steel which is through multiple forging, quenching and tempering treatment.

(3)The cylinder is inlaid with α-101 wear-resistant and corrosion-resistant alloy bushing, which has better performance than general alloy bushings in these aspects.

3. Twin screw main extruder


(1)Main motor: Imported "WEG"or "SIEMENS" Variable frequency motor. The frequency

converter will automatically change the frequency. The operating current will always run between 80%, 50%, and 30% of the rated power. This will greatly reduce the motor's operating current and achieve the effect of saving electricity.

4. Electric cabinet box


(1)Inverter: Imported Switzerland"ABB", Japan"TOSHIBA","FUJI".

(2)PLC: Imported "SIEMENS" brand.

(3)Main electrical controller:"Schneider" brand.

(4)Display of electric current:Japan "OMRON" brand.

(5)Temperature instruments: Japan "OMRON" brand.

5. Gearbox:


(1)Warranty: 3 years.

(2)Concentricity deviation of output shaft and input shaft: within 0.2mm.

(3)Both output shaft radial bearings are imported "IKO"and "NSK" bearings.

6. Screen changer+Die-head


(1)Quick open die-head, convenient and fast, short flow path of the machine head and less material storage can significantly reduce the deterioration of the material's physical properties, yellowing, black spots and other defects.

During the exhibition, we have received a lot of consultations from users. They gave full confidence in the overall strength of the equipment. The exhibition provided TENGDA with the direct communication to market. TENGDA Machinery will integrate resources more fully on the existing basis and will be continuously on the way to develop and improve machine performance, providing users with more excellent twin screw extruders
