Shaped silicone tube customization

According to the characteristics of silica gel, a silica gel extruder is designed. Under normal circumstances, the length and diameter of the screw are relatively short, which can save energy and facilitate the molding of silica gel. In the production of a single-layer extruded silicone tube, an improved silicone extruder is usually used, and then a T-die is equipped to squeeze the extruded silicone tube from the extruder vertically downward to make the extruded extruded silicone tube Directly through the vulcanization equipment located below the die. Adjust the extrusion speed of the silicone extruder and adjust the vulcanization synchronization of the equipment.

The extruded silicone tube produced by this production process has no scratches on the outside, which improves the yield of the equipment and is well received by customers. Silicone rubber products are easy to vulcanize. We choose the length of the vulcanizing equipment according to the size of the extruded product. If the product is too large, the vertical vulcanization section is usually replaced by a high-temperature sizing section, and then vulcanized after high-temperature curing through a vulcanization box. The choice of specific extrusion silicone tube production equipment depends on the specific production conditions of the product.

After extrusion, the product is molded with a mold, and finally the hose with a core is put into a vulcanization box for vulcanization. Some extruded silicone hoses are composite hoses. The production process of composite extruded silicone hoses is more complicated. It depends on the structure of the product and determines which equipment or production process to use. For example, some composite silicon pipes are connected with two composite dies for co-extrusion and vulcanization to complete production.

However, some extruded silicone tubes have interlayers in the middle. The production of such extruded silicone tubes is produced by two silicone extruders for on-line extruder production. Usually, the middle layer is used to extrude the silicone tube. Need to use vulcanization tank for production. The production process of vulcanizing products under pressure with a vulcanizing tank is usually called compression vulcanization. The vulcanization method of extruded silicone tube should be selected according to the formula and structure of the product.
