Manufacturing and Molding Weekly Meeting
Dec 31,2025
Recently, during inspections of the manufacturing and molding sites, senior company officials identified numerous issues. These findings clearly highlight many shortcomings in on-site management and also reveal certain gaps still present in our daily management practices. Therefore, at the weekly molding meeting, we briefed all vulcanization personnel on these identified issues, laid out plans for the next phase of work, and put forward the following requirements:
Starting from the source, striving for excellence.

May they enjoy good health and a fulfilling life in the days ahead, and may they have another chance to “try their luck again” in a brand-new chapter of their lives.
Finally, someone has clearly explained how to improve the “compression set” of rubber products.
Nov 28,2025
Compression set is a key indicator for assessing the ability of rubber materials to recover their original shape after being subjected to compression at a specified temperature and for a given period of time. It comprehensively reflects the viscoelastic properties of rubber, its vulcanization state, and its resistance to aging. This article delves into the mechanisms underlying the formation of compression set and the relevant testing standards. Focusing specifically on nitrile rubber, ethylene-propylene rubber, silicone rubber, and fluororubber, it systematically proposes concrete formulation adjustments and process improvements aimed at reducing compression set, thereby providing practical guidance for rubber formulation engineers.
