Custom Moulded Products and the Importance of Design Specifications in Producing Them
The creation of a products that would include moulded parts would need a design drawing for manufacturers to follow. Custom moulded products and products can be manufactured through the specifications that the design would provide. A specification drawing will show the elements and patterns of the design just like the architectural blueprints. A silicone moulding manufacturer will have an idea on what a moulded silicone part looks like when finished by looking at the design specification drawing. Features of the design, such as the size, shape, colour, thickness, material and pliability, are shown on the specification drawing.
A computerized program is one of the most common methods that will supply the design specifications of silicone moulding manufacturers. A product engineer will be able to create a two dimensional and three dimensional drawings with the sue of some software, and then these drawings are saved in an electronic file. The parts manufacturer will read the electronic file format, converts the digital mechanical designs into a real life custom rubber parts, and this is done with the use of compression moulding or liquid silicone injection moulding 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. To ensure the production of all parts are uniform and within tolerance, each requirement is spelled out.
New designers of custom keypad technology may need assistance from the rubber molding manufacturer’s engineers. These engineers can provide recommendations on the set of standards and design that will serve as guide. Know that in designing products that include keypad technology, you would need a minimum key pitch dimension of 0.080, and that the clearance between a key and a bezel could be 0.012. By following these mechanical design considerations, the manufacturer can then create a quality custom keypad. Be aware also of the distance from the edge of the keypad’s matte to a key’s diaphragm that is specifically recommended.
The use of coating is the other important information needed by a manufacturer to know. Abrasion resistant, chemical resistant or conductive coatings, are to be coated on the moulded silicone parts depending on the purpose. These coatings will provide extra protection of the parts against the outside world. Aside from making the parts last longer, coatings would improve also the performance of the parts. On military rubber keypads, coatings are especially helpful in rugged conditions.
In order for a manufacturer to create the required moulds, all of these necessary information have to be supplied.
