Tingyi (Master Kong) Technical Visit – Food-Grade Sealing Solutions

This week we had the pleasure of welcoming the technical team from Tingyi (Master Kong) Holding to our Guangzhou facility for an in-depth technical sharing session on rubber materials for the food and beverage industry.

Our engineers walked the visitors through a complete five-part program: an overview of our key customers across the F&B sector, a walkthrough of our full production workflow from drawing to delivery, a systematic comparison of seven sealing rubber materials — NBR, HNBR, EPDM, FKM/Viton, PTFE, AFLAS and HPU — with temperature ranges, hardness profiles and application guidance for each, a practical methodology for selecting the right elastomer based on media, temperature, pressure and static/dynamic service, and finally our storage guidelines to protect seal integrity over time.

It was followed by a lively technical discussion between the two engineering teams and a hands-on tour of our production and inspection areas.

At Lepu, we believe the best technical conversations happen face to face. When a global F&B leader like Tingyi sends its engineers to your facility, that is not a sales pitch — it is a real engineering review, and we treat it as such. This kind of direct collaboration with end-user manufacturers is what keeps our seal designs grounded in real-world application needs.

If you are working on food, beverage, dairy, or pharmaceutical process equipment, we would love to talk about how our 27+ years of sealing experience can support your operation.
