we areSilica Sol Mould Factory, It can be known that silicone products can be divided into three categories according to different molding processes.
Molded silicone products
Molded silica gel products are usually molded by high-temperature molds, after putting solid silica gel raw materials added with vulcanizing agents, pressure is applied through a vulcanizing machine, and high-temperature sulfur is solidified. The hardness of molded silica gels is usually 30°C-70°C. The raw materials are matched with the color paste to adjust the color according to the Pantone color card number. The shape of the mold determines the shape of molded silicone products. Molded silicone products are currently the most widely used in the silicone industry. Mainly used to make silicone industrial accessories, buttons, silicone gifts, silicone bracelets, silicone watches, key cases, mobile phone cases, silicone kitchenware, silicone mats, ice trays, cake molds, etc.
Extruded silicone products
Extruded silicone products are usually formed by extruding silicone through an extrusion machine. Generally, the shape of the extruded silicone is long and the tubular shape can be cut at will. However, the shape of the extruded silicone has limitations and is widely used in medical equipment and food machinery. use.
Liquid silicone products
Liquid silicone products are injection-molded by injection molding of silicone. The products are soft and have a hardness of 10°C-40°C. Because of their softness, they are widely used in simulating human organs, medical silicone breast pads, and so on.
Special silicone products
Special silicone products are based on the chemical properties of silica gel or the addition of some auxiliary materials. Special silicone products can also have high temperature resistance (up to 330 degrees), food grade (fully comply with US FDA, LFGB standards), medical grade, and flame retardant grade. , By adding auxiliary materials, it can also have luminous, negative ions, discoloration, and other characteristics.
