Before preforming and molding, it should be heated on a clean open mill. There is no need to thin and pass during the heat smelting, and the rubber material can be produced after the softened roll is well formed. The rubber material of the just-out piece cannot be overlapped, and can be placed on top of each other after cooling to room temperature.

Pre-forming: According to the requirements of molds and products, the film is pre-formed with the same size, shape and reset. Rubber parts manufacturers should beware of all possible pollution during the pre-forming process. Next: The oil seal compound in the fluorine rubber compound series compound has been fully considered in the production of the adhesion to the metal skeleton. The surface treatment of the metal skeleton is necessary, such as phosphating or sandblasting.

Rubber moulding: The mould is preferably chrome-plated or high hardness. Spraying release agent on the mold during molding will get better release effect. The molding temperature of rubber parts is 160℃～190℃, and the molding time is generally 3～7 minutes, which depends 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 blast device, so as to maintain a uniform and constant temperature and discharge the second Stage vulcanized volatiles.

Packaging form of rubber products: Fluorine rubber compound series packaging form: 180*290*340 carton. Each piece of rubber material is separated by PE film and packed in a sealed PE bag. Each carton has two bags totaling 25 kg. The product code, batch number, box number and manufacturing date are printed on the label on each packaging box on.
