Rubber raw material itself is non-toxic and tasteless, but after vulcanization and high temperature molding, rubber silicone products will have a little smell, which is a normal situation, and in natural ventilation for two or three days, the smell will naturally disappear, does not affect the quality of silicone products. Since the raw material of pure silicone is tasteless, how does the smell come from?
Rubber raw material itself is transparent and tasteless, but after adding and mixing toner and vulcanizing agent, and then through the compression process, the smell will be produced in this process, but this smell does not affect the quality of the product, but also can be eliminated by itself. But if the smell of the products is very pungent, it needs to pay more attention, the factory may used unqualified rubber raw materials or vulcanization agent.
How Is the Silicone Keypad Made??
1, Materials preparation: including raw rubber mixing, color matching, raw material weight calculation, etc
2, Molding processing: the use of high pressure vulcanization equipment, so that the silicone raw material into solid forming.
3, Edge Removal: the silicone product out of the mold will have some useless burrs and residual hole materials, which need to be removed; This process is processed by manul, or use the punch machine.
4, Silk screen printing: this process is only used in some silicone keypads with patterns on the surface, such as the letters, number or etc. on the silione keypad. In order to facilitate the user to operate it, it is often to screen printing the corresponding characters of the keypad in the corresponding position.
5, Surface treatment: surface treatment including dust removal with air gun.
6, Oil printing: silicone keypad in the ordinary state is easy to absorb the dust in the air, and has a certain viscosity. Spray a thin layer of Silicone oil on the surface of the silicone key, which can prevent dust and ensure the feel.
7, According to the requirements: Glue, Laser etching, Key life detectiono, optimization of packaging, etc.
Rubber keypads may seem simple, but their production involves precision engineering and material science. Whether you’re designing a new product or just curious about how everyday objects are made, understanding this process reveals the hidden complexity behind a tiny but crucial component.
