Runners - Subchannels that branch off from the sprue and into the part cavities. These are used for mold tools that contain multiple part cavities.

It may take some time to learn how much pressure to apply to the handle when filling a mold. If you press too hard you will end up with lots of plastic flash on your finished piece as material will ooze out between the mold halves. If you don't press hard enough you could end up with an air pocket left in the mold.

Low volume injection molding finds applications in diverse industries. It benefits prototyping, allowing for iterative design improvements before full-scale production. Niche markets benefit from the flexibility of low volume production, enabling customized products for specific customer segments. Furthermore, low volume injection molding caters to limited production runs, addressing demand fluctuations and reducing inventory costs.

For the injection molder demonstration, a pre-existing mold will be provided and the person must successfully injection mold the part. They should demonstrate proper adjustment of height to fit the mold, setting up for injection (filling the hopper, setting the temperature, and aligning the mold under the nozzle), injecting, and removal of the mold and part from the mold.

Once the mold is ready, the injection molding process begins. It comprises several steps, starting with material selection, where the appropriate resin is chosen based on the desired properties of the final part. The material is then heated and injected into the mold cavity, following which it undergoes a cooling phase. Finally, someone opens the mold and ejects the finished part.

Quality control is paramount in low volume injection molding to ensure the production of high-quality parts. Inspection techniques, such as dimensional analysis, visual inspection, and functional testing, verify the part’s conformance to specifications. Testing procedures, including mechanical, thermal, and chemical testing, further validate the part’s performance.
