One of several challenges with using silicone rubber keypads may very well be that the custom keypads do not stick to acrylic surfaces. When a stationary silicone rubber keypad is very important to the design and use of the acrylic solution, new technology can be used to resolve this problem. A special adhesive coating may be applied for the custom keypads to ensure that they stick to the product's acrylic surface.
One of the attributes of liquid silicone injection molding is its durability. For the reason that a rubber keypad has some give to it, it performs properly with tough objects, including acrylics. During the assembly procedure of all parts should be lined up precisely in order for the design to function. Following the rubber keypad has been made, the unique adhesive coating is applied. During the assembly process, the custom keypads are placed and secured. Other components, for instance covers or frames, can then be added.
Bonding silicone rubber molding and acrylic became an issue with all the elevated use from the membrane switch sector. The underside on the silicone rubber array does not bond effectively with all the surface, which created numerous styles inefficient. Equivalent to applying a piece of cellophane tape to a brick or liquid surface, the item would not stick together. The creation of a new and contemporary adhesive coating fixes this difficulty, enabling bonding involving liquid silicone injection molding elements and acrylics. It truly is resistant to higher humidity, intense temperatures and quite a few solvents. Consequently, membrane switches may be applied much more extensively.
The use of this bonding coating on custom rubber keypads has been adapted to several distinct types of items, such as these in telecommunications, automotive, laboratory instrumentation, industrial equipment, customer electronics and aerospace. Because the technologies was created by a business that is International Site visitors in Arms Regulations (ITAR) certified, it might also be applied in a lot of military-related products.
When building a design and style that utilizes silicone rubber keypads and acrylic components, the designer could wish to use colors, as an alternative to have a clear product. Liquid silicone injection molding can be color matched to practically any shade making use of specially developed inks. Because of this, the product can be any color requested, using a second colour of printed lettering around the rubber keypad showing up clear and legible, unaffected by the adhesive coating.
