Some of the new brand products developed by customers are powder materials. The traditional Apron dryer is not suitable for drying powder materials. In order to solve this problem, we have been studying and comparing this situation with studying from Italian Microwave Engineering Technology company. The customer's materials have been tested in this process from time to time. The feedback from the customer has been favorable. The Walsun Electromechanical will promote the commercial application of the new microwave drying technology in the synthetic rubber industry to solve the practical difficulties of customers.
