Specialization in Sintered Rings
Sintered rings are unique self-lubricating rails for high speed rotating travelers to wind diverse yarn on bobbins for spinning and twisting. These are made by Daeyoung’s proprietary powder metallurgical technology to guarantee excellent quality and highly efficient production of yarn.
In the initial start-up, one can use high-performance sintered rings more effectively when carrying out warmingup operations for excellent fitting of the sliding surface between the ring and the traveler. The inside surfaces can be wiped with a soft and clean cloth to prevent yarn stain before applying ring oil.

Specialization in Sintered Vents
Sintered vents are unique venting plugs with a large number of straight, parallel and uniform pores made by Daeyoung’s proprietary powder metallurgical technology.
Their characteristics include high venting efficiency, longlasting durability, reduction of casting defects, high casting productivity, etc. First, their porosity rates are 5-30 times higher than ordinary venting plugs. And they work with thin products with high thermal conductivity and rust prevention.
