One Liangyu’s partner, is one of the 20 most famous enterprises in the world, with hundreds of history in US. As Liangyu provides a better mold quality and innovative manufacturing services of the respirator face shield, this customer finally chooses Liangyu as long-term business partner for remaking the face shield mold,  although they already have the current mold for mass production.

It not only has strict requirement for the airtightness in assembling, but also has requirement for international standard. What’s more, during  the tension test, the face shield should not get cracked after inserting copper nuts.  Therefore,  this is a typically high level  product which requires multiple strong manufacturing technologies.

After the most  vigorous verification process, from mold design to product mass production, Liangyu finally develops a customized mass production standard of this model, in line with all requests of the customer. Thanks to this successful project, Liangyu not only gains recognition from the customer, but also establishes a long-term strategic cooperation relationship.
