Requirements in Producing Custom Moulded Rubber Products
The creation of a products that would include moulded parts would need a design drawing for manufacturers to follow. Specifications will be shown on the design that will enable the production of the custom moulded rubber products and parts. Just like the architectural blueprints, the drawing specifies the pattern and all elements of the design. And so, manufacturers of silicone moulding will refer to the design specification drawing in order to know what the moulded silicone parts would look like once completed. Among the features of the design that will be shown on the specification drawing are the size, shape, colour, thickness, material and pliability of the design.
A computerized program is one of the most common methods that will supply the design specifications of silicone moulding manufacturers. With the aid of some software, the product engineer can create drawings in two dimensional and three dimensional, which are then saved in an electronic file. A real life custom rubber moulded part is being produced by the manufacturer after reading the electronic file format, which was done by converting the digital mechanical designs with the use of a compression moulding or liquid silicone injection processes.
An example of parts is the design of military rubber keypads, of which the dimensions are described and laid out on the specification drawing, and these specifications are the height, width and thickness of the design of the parts. Shown on the specification drawing are the needed materials, colour, printing process, the ink colour and so on. All requirements when manufacturing military rubber keypads are specified to ensure production of all parts are uniform and within tolerance.
If you are new to designing custom keypad technology, the rubber moulding manufacturer’s engineers could help you in the process. These engineers can provide recommendations on the set of standards and design that will serve as guide. It is good for new designers of custom keypad products to have knowledge that the minimum requirement of 0.080 for the key pitch dimension is needed, plus a clearance of 0.012 for key and bezel is also needed. When the mechanical design specifications are followed, a quality custom keypad can be manufactured. Know also that there specific recommendations of the distance from the edge of the matte of the keypad to the diaphragm of the keypad.
If you are the manufacturer, it is also important that you know what are involved in the use of coatings. Depending on the intended use, moulded silicone parts are to be coated with abrasion resistant, chemical resistant or conductive coatings. With these coatings, the parts will be given extra protection from the environment. Coatings can also improve the performance of the parts and make them last longer. Rubber military keypads will be given protection especially in rugged conditions.
The manufacturing of these moulds can then be done by the manufacturer when all the necessary information are supplied.
