Yantai Donghui Powder Processing Equipments Co., Ltd keeps expanding its global influence by upgrading core powder coating equipment. Among all core components, the twin‑screw extruder has drawn wide attention from overseas buyers in recent overseas project cooperation. Together with high‑speed mixer, ACM grinding mill, powder coating production line and supporting auxiliary equipment, it forms a complete technical chain for powder coating manufacturing.
Many overseas clients face pain points such as unstable melting effect, high energy consumption and frequent component wear in actual production. To solve these industry difficulties, Donghui has carried out repeated tests on material selection, screw structure and temperature control system of the twin‑screw extruder. The optimized equipment achieves stable plasticizing performance for different formulas, whether general‑purpose powder or high‑end special formula powder.
Before extrusion work, the high‑speed mixer completes homogeneous premixing of various raw materials. After extrusion melting, materials go through follow‑up procedures and finally enter the ACM grinding mill for accurate particle size treatment. When matched with complete powder coating production line and different auxiliary equipment, the whole system can realize continuous automatic production. It can meet production demands from large factories as well as small‑scale laboratory research and development.
At present, many overseas partners have adopted Donghui’s full‑set solutions. The company provides one‑stop service covering scheme confirmation, equipment production, remote guidance and after‑sales maintenance. The local feedback shows that modified twin‑screw extruder effectively reduces failure rate and improves finished powder qualification rate.
Donghui states that they will continue to focus on the real demands of global manufacturers. Continuous investment in research and development will be put into powder coating equipment, to deliver more practical and efficient production solutions for worldwide customers.
