Necessary Things in Specifying Custom Moulded Parts
The creation of a products that would include moulded parts would need a design drawing for manufacturers to follow. Through the design, specifications are identified that are important in producing the custom moulded rubber parts and products. A specification drawing will show the elements and patterns of the design just like the 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.
A computerized program is one of the most common methods that will supply the design specifications of silicone moulding manufacturers. There are several software that help the product engineer to create two dimensional and three dimensional drawings ,a and then these drawings are saved in electronic files. 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. Through the specification drawing, the description of the required material, colour, printing process like ink color, are shown. A uniform manufacturing of all parts and within tolerance level are ensured as military rubber keypads are products since each requirement is spelled out.
If you are new to designing custom keypad technology, the rubber moulding manufacturer’s engineers could help you in the process. By provide set of standards and design recommendations, these engineers can help guide new designers. 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. 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. The moulded silicone parts, depending on their intended use, are to be coated with abrasion resistant, chemical resistant or conductive coatings. The parts will be given extra protection from the outside world because of the coatings. Aside from making the parts last longer, coatings would improve also the performance of the parts. Rubber military keypads will be given protection especially in rugged conditions.
All the necessary information needed are therefore to be provided to a moulded silicone manufacturer to enable them to create the required moulds.
