In a recent survey conducted by an agency, Weiwan Sealing said that the company’s PPDI new material system products are currently mainly used in high-end application fields such as excavators and breakers. At present, the complete set of seals in the small excavation field are basically in supply, and the medium and large excavation field is still undergoing professional testing, and the test is expected to be completed next year. Small hammers in the field of breakers have been supplied in small quantities around June and July this year, and the test of sledgehammers is still in progress, and it is expected that the test will end soon. The product testing of the PPDI material system in the aftermarket is also progressing smoothly. The company is optimistic about the application of the self-developed PPDI new material products in the field of excavators and breakers.
