Manufacturing Process
The linear molecular structure of plastic rubber is transformed into a three-dimensional network structure with a three-dimensional network structure, the inner layer is colloidal, the middle layer is reinforced with SNT series nylon 66 ultra-high-strength industrial wire cord fabric, and the rubber curved ball with outer rubber layer composite is vulcanized by injection pressure method, and is composed of cast iron and forged metal flanges.
