Rapid-Fire Method for Faster Part Production

Our Rapid-Fire Method can cut production time per part by 50%.

Initially, we started 3D-printing face shields but couldn’t meet the demand. To optimize production, we built a small injection machine. However, each face shield frame required a wait of 7 to 8 minutes due to the heating of plastic flakes.

To address this, we developed the Rapid-Fire Method. By using our extruder, we produce and process heated material immediately.

  1. Instead of filling the injection machine with flakes, use your extruder to produce hot material. Remove the nozzle to extrude thick strips. Immediately fill the injection barrel with these strips.

    In the extruder, the plastic is well-mixed and heated, making it ready for processing in the injection machine.

  2. Insert the heated material into the injection machine barrel. Extrude until slightly thinner than the barrel's diameter for optimal loading. If too thick, loading becomes difficult; if too thin, it compromises capacity.

  3. Position the mold under the injection machine and inject the melted plastic. Here, we utilize a professional mold for face shields. To optimize efficiency, assign one person to reload the machine while another manages the mold. This process results in a cycle time of approximately 2 minutes per part.
