First, hardware is divided into many types, and silicone overmolding technology, such as bonding is not strong, most likely because of the hardware and adhesive can not be bonded, usually the benefits of bonding is to have hardware, glue and glue and treatment agent and other several methods to practice, and the type of hardware is divided into different materials need to choose different chemical glue and bonding process processing, such as anodization of aluminum and its alloys, copper plating of steel treatment, need to use chemical method. After treatment of the metal surface, the treated surface should be promptly coated with adhesive, affixed with silicone rubber or immersed in inert solvents.
Second, the glue and treatment agent selection, glue is an important auxiliary material for the hardware package, different materials choose different glue, and silicone tableware and hardware bonding requires a relatively strong liquid glue, need to stick to silicone and hard metal materials at room temperature, the treatment agent is certainly more than important, hardware above such as treatment agent for uniform coating, will lead to long-term use of silicone kitchenware local sliding and other phenomena.
Third, the bonding method of the product, different silicone tableware choose different bonding methods, silicone kitchenware is usually divided into hot-pressure curing as well as cold bonding process, molded solid talk method is mainly to brush glue in the mold after high temperature molding, the product curing to achieve the bonding effect, cold bonding method is to choose to use liquid glue manual or mechanical bonding after the static or high temperature drying method, different methods for this different silicone products The main relationship with the structure of silicone products!
Fifth, the structure and positioning of the product, silicone products, the bonding effect and the structure of the product, as well as the fixed position is very relevant, so try to increase the bonding area, improve the bearing capacity of the bonded joint, the bonding length in the direction of the force should not be too long, should try to increase the bonding width, to know that angled bonding is better than right-angle bonding, plane is better than the angled surface, so the product in the design of the time such as the need to bond as much as possible The best bonding point of the product to find.
To sum up, if the businessman custom hardware wrapped kitchenware, in order to manufacturers to produce products more in line with the required standards, you need to choose the right quality manufacturer. Because quality silicone products manufacturers in the production of silicone cookware, generally will use food-grade FDA or LFGB standard silicone raw materials, through high-temperature vulcanization molding or encapsulation refined from, in the production process, processing and production experience is more.
