Pre-forming: According to mold and product requirements, pre-form the film with the same size, shape and reset, and beware of various possible contamination during the pre-forming process. Next: The oil seal compound in the fluorine rubber compound rubber series has fully considered the adhesion to the metal skeleton during production, and the surface treatment of the metal skeleton is necessary, such as phosphating or sandblasting. Recommended Adhesives: Thixon 300/301, Chemlok 5150
Molding: The mold is preferably chrome-plated or high-hardness. Appropriately spraying release agent on the mold during molding will get better demoulding effect. The molding temperature is 160°C to 190°C, and the molding time is generally 3 to 7 minutes, depending on the thickness of the product.
Vulcanization: Fluorine rubber products need to be vulcanized in two stages to achieve the best physical and chemical properties. The usual vulcanization conditions are 230℃@16～24H. If the parts are bonded to metal, 200℃@16～24H is recommended. The second-stage vulcanization oven should be equipped with a blower device, so as to maintain a uniform and constant temperature, and discharge the second-stage vulcanization in time. The volatiles of segment vulcanization.
