As machining capabilities become more and more sophisticated, mold manufacturers are moving towards machining parts as close to near net shape as possible in the milling process. Grinding and polishing can be time-intensive and expensive operations. The more we can shorten these processes, the more we drive manual work and cost out of an operation.

Traditionally, ball nose tools have been used to try and finish parts as close to near net shape as possible. This is accomplished by using the radius at the end of the tool and taking small step over tool paths to minimize the scallop to an amplitude that fits within the surface finish specification. The advantages of this approach are that it eases programming, makes it possible to reach deep into cavities and allows the inclination angle to be versatile. The main disadvantage of using this process is that it requires many tool passes, resulting in very high cycle times.

The Effect of Pressure and Temperature on Part Quality and Dimensions

To start, let’s review how plastic makes a journey from pellet form to a liquid or a sliquid (a semi-scientific term that identifies a substance that is neither a true liquid or solid) in the injection unit.

For those unfamiliar with British Thermal Units (BTU), it represents the amount of thermal energy necessary to raise the temperature of one pound of pure liquid water by one-degree Fahrenheit. To melt plastic, there’s a certain amount of BTU content that must be added to a semi-crystalline, like polypropylene, to break that structure down and turn it into an actual liquid. Breaking these crystal structures takes an enormous amount of energy in comparison to amorphous resin. Amorphous materials, like polycarbonate, technically never melt, they only get softer.
