One of the challenges for injection molders is efficiency. The cycle times for plastic parts can range from 30 seconds to more than a minute. One of the primary contributors to that time and one of the longstanding constraints is cooling time. It is always a trade off of waiting for the parts to properly cool to avoid warping and shrinking, and maximizing productivity.
The concept of additive manufacturing or what used to be considered or associated with laser sintering, is a way to potentially improve the productivity and efficiency of your mold by taking advantage of conformal cooling.
The additive manufacturing process allows the toolmaker to lay down one layer of the mold at a time, creating the ability to get away from straight line drilling of cooling channels that are not as efficient. By utilizing conformal cooling channels that conform or run closer to the shape of the part allows for more efficient cooling process, and has led manufacturers to realize reduced cycle times by as much as 25-40%!
The creation of conformal cooling channels is something that must be considered when designing the tool, and is often considered an optimization task. In many of the mold software tools, are able to simulate the conformal channels, and their impact on the tool.
Making your operation more efficient is not easy. Additive manufacturing concepts for tool creation is one concept that can potentially have a very positive impact.
