Customization Overview FAQs for Enclosures

Customization Overview


Polycase does not provide first articles. Instead, you submit your drawings with your order, and our engineering team reviews them and creates production drawings for your approval. Production will not begin until those drawings are approved, ensuring the final product is manufactured to your specifications.


If you'd like to test a prototype before moving forward, you can order a single piece since we have no minimum order quantities. We guarantee the final product will conform to the approved production drawings.


Need help ensuring your components align with your design? We also offer fit-to-sample services, where you send us your components and our engineers create the production drawings for you, eliminating uncertainty before production.

While Polycase strives to avoid overages, we reserve the right to over-ship your order by 1 unit for orders under 25 units, or up to 5% for orders over 25 units, with a maximum of 25 additional pieces. If your order includes compatible accessories, their quantities may also be adjusted to match any overages.

When a customized enclosure is revised, the original version becomes obsolete and cannot be ordered. If you later decide you need to order the original version, we’ll need to set it up as a new custom part.

This means:

• A new part number will be created

• The one-time fees will apply

A fit-to-sample is a reverse-engineering service where you send Polycase your physical components, and our team custom-designs the enclosure to fit them perfectly. We highly recommend this option if you are unable to provide exact drawings or are uncertain about your current designs.

The cost typically ranges from $150 to $600. In rare occasions, the cost may extend above this range. The quote surfaces and features may change depending on the submitted components. We’ll ask you to send all relevant components, including circuit boards, custom-machined enclosures, and panel mount connectors. Once we receive your items, we'll confirm the price and proceed with your custom order, returning your parts along with the completed enclosure.

During the fit-to-sample process, we will submit drawings for approval along with any additional notes or questions. You will need to confirm that all the features you believe are required are accounted for. You will also need to acknowledge any notes or questions. Please note that sometimes these sizes and locations will change after approval.

Production drawings are created after a custom order is placed. Polycase will create production drawings from your drawings, upload them to your account for review, and require your approval before starting production. Production will strictly follow our production drawings, so it is critical to verify their accuracy before approval. For the standard 3-week lead time, production files are typically completed within 1-2 weeks. We do not provide first articles.

To find all your custom quotes, log in and navigate to your Polycase account. There, you'll find your quotes under "My Quotes & Custom Parts."

If you're part of a company account, your personal quotes will still be under "My Quotes & Custom Parts," while quotes created by your colleagues will be listed under "Company Quotes & Custom Parts." This system helps you easily distinguish between your quotes and those created by your colleagues

These are setup charges applied to the first order of a new custom project. They cover the setup work required by our engineering team to review your drawings, create production drawings, and generate programming files for the machines. You won’t be charged these fees again after the initial order unless you revise the machining or graphics. Any revisions that require engineering involvement will result in new setup charges.

A new custom part is a stock product with your requested machining or graphics, assigned a unique part number and one-time setup fees.

A revision updates an existing custom part and also includes one-time fees. Important Note: Once ordered, the existing version becomes obsolete and can't be reordered.

To order a custom product on behalf of your customer, you need their Polycase custom part number, quote number, or Polycase drawings. Alternatively, your customer can contact Polycase directly to authorize you as the purchaser for future orders. Polycase values and protects our customers’ privacy. 

Polycase's tandard lead time for customized enclosures is three weeks, provided the unmodified item is in stock. One and two week expedite options are available at an additional cost and are shown on your quote.

Mounting bosses are built directly into the mold. so Polycase cannot change the mold, but we can supply the cases without bosses or machine the bosses out. We offer adhesive standoff's so you can place your mounting bosses in the exact location you need.

Alternatively, we can machine countersunk holes in the locations that the bosses are needed. You would then fasten stand-offs to the enclosure with countersunk screws in the machines holes. Then your PCB can be screwed to the top side of the stand-offs inside the enclosures.

We do not offer any custom molding or tool building, we sell off-the-shelf enclosures and we cannot change the shape or size of the enclosures. However, we do offer secondary services to customize your enclosure to fit your needs. We offer CNC machining and digital printing.
