Product use: The ring press can be used for all-round testing with various materials. In terms of paper packaging materials, it can perform a variety of paper quality tests, that is, five kinds of tests, such as ring pressing (RCT), flat pressing (FCT), edge pressing (ECT), bonding (PAT) and general compression resistance (CMT). It is a testing equipment that combines multiple functions. Product parameters: 1. capacity: 10,20,50,100,200kg (optional); 2. Accuracy: ≤1% 3.
