Prototype Injection Molding
Prototype injection molding is a form of injection molding that is used to make short run batches, or single products used for prototype purposes. These prototypes are made in the same fashion as long run batches, but they are used to show clients and consumers an example of the product in order to work out more design details or to get approval before spending the time and the money on the long run batch of injection molded parts.
Materials Used for Prototype Injection Molding
As stated before the prototype injection molding process works the same as the injection molding process in that it is used to manufacture parts through the process of injecting a molten plastic material into a mold where it hardens and goes through secondary processes until it is in the final finished product form. There are a number of different materials that work with this type of process, however, thermoplastics are the most common due to their versatility and useful properties.
The thermoplastic material passes through a heated barrel where it is mixed and then forced into the mold; once the mold is filled the material is cooled and hardens in the shape of the mold. The mold is designed in order to fit the specifications and requirements of the applications; this is where the prototype comes in handy because if there is something wrong with the mold it will show on the prototype.
Applications for Prototype Injection Molding
Prototype injection molding can be utilized for a number of different applications such as:
- Wire Spools
- Packaging
- Bottle Caps
- Automotive Parts
- Musical Instruments
- Tables and Chairs
- Mechanical Parts
- Gears
