Requirements in Producing Custom Moulded Rubber Products
Manufacturers would need a design drawing in order to produce a product with some moulded parts in them. Specifications will be shown on the design that will enable the production of the custom moulded rubber products and parts. The pattern and all elements of the design are shown on the specification similar to that of an architectural blueprints. Therefore, the design specification drawing is what these manufacturers of silicone moulding would look at so that they will have an idea on what the moulded silicone parts would look like once done. Features of the design, such as the size, shape, colour, thickness, material and pliability, are shown on the specification drawing.
Silicone moulding manufacturers are supplied with design specifications through computerized programs. 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. On the specification drawing, the required materials, colour and printing process involved like the ink colours, are placed. All requirements when manufacturing military rubber keypads are specified to ensure production of all parts are uniform and within tolerance.
The assistance from the rubber moulding engineers of a manufacturer could help new designers of products like custom keypad technology. These engineers can provide recommendations on the set of standards and design that will serve as guide. If you are new to designing products involving keypad technology, know that a key pitch dimension of 0.080 and a key and bezel clearance of 0.012 are recommended. 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.
The use of coating is the other important information needed by a manufacturer to know. Depending on the intended use, moulded silicone parts are to be coated with abrasion resistant, chemical resistant or conductive coatings. These coatings will provide extra protection of the parts against the outside world. Further importance of the coatings would be that it improves the performance of the parts plus making 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.
