Corners

Two key points to keep in mind when designing part corners: the mold is machined from steel, and it’s easier to machine a radius than a square corner.

Therefore, whenever possible, the part should display round corners when viewed from the top. When viewed from the side, the edges should be square.

Also, due to the flow characteristics of the molten material during the molding process, square corners tend to be weaker than rounded corners. To ensure dimensional stability, we recommend a minimum radius of 0.010 (0.254mm).
