What is high-precision plastic injection molding?
When it comes to plastic injection molding, it is important to have a clear definition in mind.
Therefore, high-precision plastic injection molding can produce components with tolerances as strict as 0.01 millimeters. In order to achieve such a result, the entire process is carefully controlled, from mold design to material selection and machine operation.
With this type of procedure, the main goal is to obtain accurate pieces with materials displaying low shrinkage rates. Thanks to this feature, the size of the parts is exact, and even the most intricate details can be replicated.
To ensure product quality at all times, high-precision plastic injection molding is performed using automated machines that, thanks to multi-axis control and accurate dosing system, can carry out real-time monitoring for delivering consistent quality outputs.
How does it work?
What are the key phases to ensure the creation of dimensional accurate high-precision injection molding?
Let’s discover how the process is performed.
- First, it is crucial to choose a design which can deliver perfectly smooth surface finish. At Idea Stampi, we always discuss the aesthetics and functional features of the mold with our customers to meet their expectations. In this co-design part of the process, we choose the most suitable material to execute high-precision injection molding flawlessly.
- Once we have customized the mold based on the customers’ requests, it is time to start designing the mold. Thanks to advanced technologies (CAD/CAM/CAE software), Idea Stampi’s skilled technicians can guarantee the utmost quality of every high-precision plastic injection molding project. Furthermore, using the VISI Flow simulation system, it is possible to craft the component and perform several test to outline the performance of the mold throughout time, optimizing the parts that are not working properly.
- The manufacturing phase is crucial, as the operator set up the parameters for the production of the high-precision plastic injection molds, such as pressure, melt temperature, and mold temperature. This configuration must be done impeccably because it could compromise production.
- The plastic material previously selected is injected into the mold cavity. High pressure is maintained through the course of the process in order to reduce every possible shift that could prevent the cavity to be properly filled.
- Once the mold it is filled, it is time for the plastic material to cool and solidify. At the end of the procedure, high-precision injection molding plastic parts are thoroughly inspected to ensure that all dimensional specifications are met.
