About Project

In the realm of modern manufacturing, precision and efficiency are paramount. The first photo showcases an impressive array of injection mold prototypes that embody these principles through the innovative use of conformal cooling designs. These prototypes highlight the synergy between advanced 3D printing techniques and thoughtful engineering, offering a glimpse into the future of mold making.

On the left, we have a transparent plastic mold prototype. Created using the SLA (Stereolithography) 3D printing technique, this clear resin model provides an invaluable window into the internal structure of the mold. The visibility of the conformal cooling channels within the prototype is particularly noteworthy. These channels are meticulously designed to follow the contours of the mold cavity, ensuring uniform cooling throughout the molded part. This results in reduced cycle times and enhanced part quality by minimizing warping and internal stresses. The clear resin prototype serves as a vital tool for designers and engineers to verify the accuracy of their cooling channel designs before moving on to metal molds.

The middle and right items are metal mold components, both crafted from ss316L stainless steel using Direct Metal Laser Sintering (DMLS) 3D printing techniques. These components are a testament to the precision and durability that DMLS offers. The conformal cooling channels, though not visible from the outside, are integrated within these solid structures, following the complex geometries of the mold cavity. This ensures optimal thermal management during the injection molding process, leading to improved efficiency and part consistency.

The right component features a protruding core, which is crucial for forming specific features in the final product. The middle component, with its machined surfaces and integrated cooling channels, exemplifies the intricate design capabilities enabled by DMLS technology. These metal prototypes not only demonstrate the effectiveness of conformal cooling designs but also highlight the robustness and accuracy of ss316L stainless steel in demanding manufacturing environments.

  • Step 1: A 3D model of the injection mold with conformal cooling channels was created using CAD software.
  • Step 2: The 3D model was sliced into thin layers and converted into a format that can be read by the 3D printers.
  • Step 3: The transparent prototype was printed using SLA 3D printing technology and SLA Clear Resin. A laser beam was used to cure the resin layer by layer according to the 3D model.
  • Step 4: The transparent prototype was post cured with UV, and then the supporting structures were removed with pliers. It was then sanded and polished with fine-grit sandpaper, sprayed with clear acrylic oil.
  • Step 5: The stainless steel prototype was printed using DMLS 3D printing technology and SS316L. A laser beam was used to melt and fuse the metal powder layer by layer according to the 3D model.
  • Step 6: The printed prototypes were removed from the build platform and cleaned of any excess material.
  • Step 7: The transparent prototype was injected with yellow dye solution to make the conformal cooling channels more visible.
  • Step 8: The stainless steel prototype was left with its raw grainy surface, and the layer lines on the bottom face were obvious without sanding and polishing.
