To successfully mass produce a consumer product, there are several important manufacturing challenges that must be overcome. Prototype models have to be molded and then tested. After the prototype, models from custom materials are made in small quantities. At such a stage, the products are ready for a test market. Actual consumers may be surveys on their experiences with using products that are in the preliminary stages of production.
One major challenge with producing a good for the consumer market is selecting the type of manufacturing techniques. For instance, some parts could be made separately and then assembled together. The costs of dividing up the parts and labor can add up and hurt the budget of a company.
Therefore, product designers and manufacturing engineers need to figure out how to mass produce an item in a single body design. In other words, a single continuous process can be used to make an entire product. Extrusion is a very effective production method of creating three dimensional products from a two dimensional design. MoldedExtrudedSpecialties.net and other sites are examples of companies that offer extrusion manufacturing solutions.
First, a flat plane is laid out to define the boundaries of the top view of a product. Then, the two dimensional cutout is filled with plastic in an extrusion process that involves injection molding. In another words, the 2D shape is vertically stretched out to yield a 3D creation. All holes and other openings are then made when a three dimensional plastic model is produced.
