Where are the benefits of shaped waterways?
According to the Bastech success case shared by 3DSystems, it can be known that the improved mold can bypass the ejector pin and the fixing screw under the blessing of the special-shaped waterway combined with the 3D printing technology. Even if the waterway is far away from the area, the ideal cooling quality can be achieved. The benefits of shaped waterways are as follows:
- Manufacturing manpower can be saved by 50%
- Save 14% injection mold production cycle
- 75% reduction in mold design time
- 16% savings in manufacturing costs

Of course, not all molds need special waterway design, because the price of special waterway is more expensive than traditional waterway. In general, products with complex shapes that cannot effectively dissipate heat, thin walls, and other products that are sensitive to abnormal temperatures and require high product quality all require molds with special waterways.
What are the manufacturing methods of shaped waterways?
Traditional CNCs for special-shaped waterways cannot be manufactured. At present, common manufacturing methods include 3D metal laser sintering and diffusion welding.
The 3D metal laser sintering method is DirectMetalLaser-Sintering, which uses high-energy laser beams to melt stacked metal powders to obtain products with specific shapes.
Diffusion welding is a planar welding technology in which two (or more) mold parts are connected under high temperature, high pressure and vacuum environments.
Compared with 3D metal laser sintering, diffusion welding has lower time and cost for making molds; but the more complicated the profiled waterway, the more time and number of parts are required for diffusion welding, and the 3D metal laser sintering method is theoretically almost unaffected. Therefore, diffusion welding is suitable for a special-shaped waterway with a simple structure.
