The reason behind this is so that the customer can receive their prototype as quickly as possible in order to either make changes to the design or approve it for mass production.
Rapid injection molding is also used in a number of other applications where time may be a factor, as rapid injection molders can generally produce a prototype in about 2-5 weeks from the start of the design phase.
The overall process of rapid injection molding does not differ much from the standard injection molding process; it is simply a more rapid approach to the process in order to get a prototype shipped faster. The process is still accomplished by injecting a molten plastic material into a mold that is designed based on the final product, where it is allowed to cool, harden, and take the shape of the mold. Once the material is hardened and removed from the mold the product goes through a series of secondary finishing processes to ensure that all customer requirements are met.
Thermoplastics are some of the most common materials used in injection molding due to their versatility and diverse physical properties. This allows them to perform well in a broad range of industrial applications. As stated before the mold is designed with the final product in mind, so it is crucial that the customer receives a prototype quickly to ensure that the final product will fit their standards and specifications.
As a customer it is important to understand your application and to communicate all of your needs, requirements and specifications to your rapid injection molding company. This is why we recommend that you consult a trusted rapid injection molding manufacturer that has years of experience and understanding, so that they can work with you to develop a product that not only meets your expectations but fits into your process and application as best as possible.
