Frequently Asked Questions

Polycase can machine virtually any size or shape opening that you may require, however all drawings will be reviewed by Polycase to ensure manufacturability. All square and rectangular cutouts will typically have a minimum corner radius of 0.031" and tolerance on machined features will typically be +/-0.005". These may increase depending on enclosure selected and feature machined. For components we typically recommend sizing your cutouts to be .040" larger than the component (or .020" for round cutouts). Occasionally, certain features may not be able to be machined or will require a non-standard approach which could increase the machining price. This would be determined when the order is placed. Contact Polycase Technical Support if you have specific questions regarding a machined feature.

We can machine any size or shape holes that you needed, on any surface of the enclosure. Polycase design engineers are happy to help you with the design if you need assistance. Based on the board and connectors you use, together we will be able to determine the best locations and sizes of holes that would work for your product.

Because the enclosure covers are created to fit tightly to the enclosure, once the base is machined down the covers will no longer fit. So this is only recommended for potting boxes or applications that do not require a cover.

Yes, we can machine down the height, or remove, the mounting bosses. Because they are only ¼” tall, often they do not interfere with the desired application, but if they do, they can be machined out or made shorter. Additionally, some of our enclosures are available with or without the bosses.

I just received my first order from you. Machining is perfect. The concept, and execution of your concept, is outstanding. The results of the product exceed my expectations. Extremely happy with the process and the data you provide to result in exactly what I had imagined....Probably one of the more satisfying parts of this [product development] process: when you know exactly what you want and without difficulty can get exactly that.
