The Protomold Injection Molding Process

1. Design Phase In the initial design phase, product developers create a 3D CAD model that serves as the foundation for the injection molding process. This digital representation defines the geometry, dimensions, and specifications of the part, laying the groundwork for its manufacture.
2. Quoting and Feedback Once the CAD file and specifications are submitted to Protomold, the company provides a detailed quote. This includes cost estimates, lead times, and valuable feedback on manufacturability. The feedback helps optimize the design for efficient production, reducing potential issues during the injection molding process.
3. Tooling Protomold employs high-speed CNC machines for the precise creation of molds. These molds are pivotal in the injection molding process, as they define the shape and structure of the final parts. Meticulous attention is paid to mold design and construction to ensure optimal part quality and functionality.
4. Injection Molding Production Using state-of-the-art injection molding machines, Protomold injects molten plastic material into the mold cavities at high pressures. The molten plastic fills the cavities, conforming to the mold’s shape. Cooling and solidification take place, resulting in the formation of the desired parts.
5. Finishing and Post-processing After the parts are ejected from the mold, they undergo inspection and quality control procedures to ensure adherence to specifications. Depending on the application and customer requirements, additional post-processing steps, such as surface finishing or assembly, may be carried out to enhance the final product’s aesthetics and functionality.
