AC&M: Your Go-To Custom Seal Manufacturer

AC&M: Your Go-To Custom Seal Manufacturer

Posted by Steve Diebold

For over a century, American Casting & Manufacturing has been a top seal manufacturer, so we've made it easy and convenient for customers to purchase seals straight from the manufacturer. We think that all consumers, no matter how big or small, should be able to buy seals from the manufacturer at their convenience. We want every customer, no matter how big their order is or what they need, to have a pleasant and easy shopping experience.

In order to use seals efficiently, you must pay close consideration to a great number of specifics. It could also be as simple as needing to have brand new seals shipped out as soon as possible with as few complications as possible. AC&M takes pride in the fact that we can accommodate a wide variety of consumers and always deliver results that are satisfactory or better.

So that our customers can always get the seals they need, we have made a thorough program for the quick supply of marked and bundled seals for production that can be delivered quickly. The experienced professionals at AC&M work out of a building with state-of-the-art equipment for engineering, sales coordination, production, and order processing. This enables us to provide our diverse clientele with the utmost individualized service.

ID Customization

After choosing the seal's style and size, the most common method of personalization is having plastic seals lettered with the user's ID or other information. However, the degree to which individual seals can be marked depends on their structure.

For instance, our FC1 flat metal strap seals are stamping types. While the stamping process's variations are nearly endless, it's not a good fit for images with a lot of fine detail or complicated printwork. Plastic pull-up closures, like our model AP-50, can be printed with intricate designs and extensive custom markings and information via laser or roller coating.

Company logos and other distinctive identifiers are often used as print subjects. However, it is not uncommon to also incorporate data for instruction, safety, or seal control. Our model 8001 padlock seal prominently displays the caution, "440 Volts of Electricity," while the PS360 bag seal can be ordered with a hazardous, flammability, or radioactive substance warning icon printed on it.

You can choose from a wide variety of other distinctive marking choices not listed here. We strongly recommend personalization for safety and other reasons, so don't be afraid to ask questions or make requests about how you want your items marked. Remember that a seal's distinctive design helps prevent accidental replication or misidentification during inspections.


The serial numbers on most security seals can be displayed in a few different ways. Numbers that are stamped or engraved are the most basic. However, the codes can also be included in a QR code or barcode alongside the dates and other information.

The organization's goal, location, or division can be seen from the first letter of the prefix on its seal. For instance, our CL-99 cable security seals can be installed on a valve with lettering to demonstrate whether the valve is either open or shut and what kind of fluid is passing through it.

Prefixes not only add to the number of possible ways to number something, but they can also help with inspection by making it easy to tell the difference between seals that look the same otherwise.

Color Coding

Most seals come in at least two standard hues, and custom colors can usually be produced in a short amount of time. When manufacturing smooth pull tight seals in large quantities, a unique color can be created per customer request. When it comes to the seal coatings we provide, a color scheme is an absolute must.

Differentiating seals through color helps with inspection, monitoring, and documentation. A plastic truck seal, such as model 4001, might be colored differently to distinguish between empty and full vehicles. Each truck path or type of cargo could be assigned a unique color by the user. Color coding is used on labels across all sectors.

If you want your seals to be even more secure, you should switch up their hue occasionally. It discourages making duplicate seals or using broken seals again. Those who are trying to steal covertly often resort to using old, broken seals that have been discarded as makeshift replacements. After closing a door or container, they make it look like the seal is still in place. The color of the seals in use may have been altered, rendering obsolete any previously used seals of a different color.
