Extrusion is a simple process that is used in nearly every product or prototype that has specific shape needs. The extrusion process itself is simple, the plastic is melted down and formed into the specific shaped required for the prototype. The plastic is pressed through a die, extruding out into the desired shape. There are multiple materials that can benefit from the extrusion process. Materials related to prototypes include ceramics, metals and plastics. These materials can all be used in various prototypes. Extrusion is important for prototypes because of the manufacturing process that will follow. Prototypes that are going to be turned into mass-produced products need to have solid manufacturing plans. Extrusion can be an important part of these various processes, as it provides a quick and easy way for manufacturers to create exact replicas of a part. One of the most important things for inventors and manufacturers to consider when creating their prototype is the shape of the pieces needed. Prototypes should attempt to design pieces that could also be mass-produced; inventors need to think about the die that would be used in the extrusion process when creating the pieces for the prototype. There are various factors that will determine the shape and size of the die. There are a couple tips that can help inventors and manufacturers to create foolproof dies. Attempt to create pieces that have consistent wall thickness. This will keep the die from creating uneven and unexpected thicknesses in the product. Inventors should also avoid small, sharp corners as these corners can often be difficult to create through extrusion dies. Inventors should work with their manufacturers to better understand the extrusion process. The prototype will be able to be altered to fit the profile of the extrusion manufacturing process, allowing the prototype to be mass-produced. Extrusion is a solid process that is reliable for inventors who are looking to take their ideas to the next level.
