From election voting machines to ballot boxes to voting security products in general, American Casting and Manufacturing has companies covered with security seals for elections. These come in a wide range of sizes and categories, including seals, security tape, and tamper evident labels. With these, elections on different levels will be secure.
Security seals on election equipment provide documented, tamper-evident evidence that voting machines, ballot totes, and ballot boxes have not been accessed between authorized points in the election process. They are a critical component of chain-of-custody documentation, helping election officials demonstrate to candidates, observers, and the public that equipment integrity has been maintained from pre-election setup through post-election canvass.
The election line includes pull-tight plastic seals, plastic padlock seals, cable seals, wire seals, and tamper-evident labels in multiple sizes. This range supports sealing of voting machine access ports, memory card compartments, ballot totes, ballot boxes, and election supply cases at the precinct, county, and state level, covering every physical configuration used in modern election operations.
Single-use, irreversible seals are essential for election integrity because they cannot be removed and re-applied without leaving permanent visible evidence of tampering. Any unauthorized access between authorized checkpoints, whether to a voting machine access port or a ballot tote closure, is immediately detectable. Reusable seals cannot provide this guarantee and are not appropriate for chain-of-custody programs that must withstand public scrutiny and legal challenge.
Every seal number is recorded on an official chain-of-custody form before it is applied, and again when it is verified and broken at the authorized access point. Any discrepancy between the logged number and the seal on the equipment triggers an investigation before the unit is opened. Most seals in this line are available barcoded for scanning directly into electronic records, eliminating manual transcription errors that can create documentation gaps.
Inspect the seal body for any signs of cutting, cracking, forced separation, or chemical attack. Verify that the serial number on the seal exactly matches the number on the chain-of-custody form for that specific piece of equipment. Any seal that is physically damaged, shows signs of attempted removal, or carries a number that does not match the documentation should be flagged and reported to the responsible election official before the equipment is accessed.
Tamper evident labels for election use are available in 1 x 2 inch and 1 x 4 inch sizes, with or without adhesive residue. Custom sizes and larger stock labels are also available. Labels with residue leave a visible void pattern when removed, making interference immediately apparent on voting machine panels, memory card doors, and equipment cases. No-residue labels are used where adhesive damage to the equipment surface is not acceptable. Confirm your jurisdiction's equipment specifications before ordering.
Yes. Custom colors, sequential numbering ranges, and custom printing are all available. Many election offices use different seal colors to differentiate between election types, such as primary, general, and special elections, or between equipment categories. This makes seal verification faster for poll workers and canvass staff who may be handling hundreds of pieces of equipment in a short time window.
Not always. Voting machines typically require seals sized for small-diameter access ports and memory card compartments, while ballot boxes use hasps and handles better suited to padlock or pull-tight seals with a larger shackle. Many jurisdictions specify different seal models for each equipment type, with matching serial number ranges logged separately in their chain-of-custody records.
