For more than a century, American Casting & Manufacturing (AC&M) has been at the forefront of the security seal industry, providing innovative solutions that protect businesses, government agencies, and individuals alike. Our commitment to quality, precision, and customer satisfaction has remained unwavering since our founding in 1910. Security seals are more than just a product, they are a critical component of trust, compliance, and operational efficiency.

Every seal user has unique requirements. The variety of seal types, sizes, and applications is nearly endless. This diversity makes sourcing the right seals a challenge for many organizations. AC&M has turned this complexity into an advantage, offering direct factory access that ensures every customer, whether a small business or a multinational corporation, receives the exact solution they need. Our approach combines speed, accuracy, and a deep understanding of security protocols to deliver superior results.

Personalized and Efficient Seal Solutions

AC&M’s dedication to customer satisfaction begins with personalized service. As a security seals manufacturer, every client benefits from our experienced team, who carefully evaluate individual requirements to provide recommendations that maximize security and usability. The goal is simple: high-quality seals delivered quickly, with minimal effort from the customer.

Our operations are centered in New York, where manufacturing, sales coordination, and order handling are all overseen in-house. This setup allows our team to maintain tight quality control and offer the level of personal attention that clients expect. No matter the size of the order, every customer receives the same professional service. Our staff ensures that every detail, from material selection to packaging, aligns perfectly with your needs, helping you maintain operational efficiency and compliance.

Custom Marking Options

AC&M understands that the effectiveness of a seal often depends on how well it communicates important information. Custom markings transform standard security seals into tools for accountability, identification, and safety, particularly in programs that rely on tamper evident seals to meet compliance and inspection requirements.

ID Customization: Seals can display logos, user IDs, warnings, or instructions. Metal FC1 seals use stamped text, while plastic AP-50 seals allow detailed printing. Alerts like “440 VOLTS” or biohazard symbols provide instant hazard awareness. These markings help protect tamper evident seals from duplication and improve inspection accuracy.

Numbering Options: Serial numbers enhance traceability and accountability through stamped, printed, or barcode-based identification. Letter prefixes can indicate departments or status, such as whether a valve is open or closed with CL-99 cable seals. Unique numbering simplifies inspections, reduces errors, and strengthens security programs built around tamper evident seals.

Color Coding: Color coding improves both security and organization. Plastic seals come in multiple colors, with custom options for larger orders. Different colors can indicate cargo type, route, or truck load status. Regularly changing colors prevents unauthorized reuse, and modern techniques allow metal seals to be color-coated for added distinction.

ID customization, unique numbering, and strategic color coding ensure every seal performs effectively and securely. These features allow organizations to maintain accountability, prevent unauthorized access, and streamline inspections, making custom seals an essential part of any security strategy.

Custom Packaging and Handling

AC&M not only focuses on the security features of the seals, but also on their packaging and handling, including specialized products such as cable seals. Proper packaging can streamline inventory management, facilitate distribution, and improve operational efficiency.

We provide standard packaging solutions, but we also offer custom configurations for organizations with specific needs. This includes inner packs of bags or boxes, mixing different seal models or colors within a single carton, and special labeling for easier identification. For resellers, plain packaging is available, while bulk clients can request custom pallet quantities. These solutions ensure that every seal arrives organized, easily identifiable, and ready for immediate use.

Our modern warehousing capabilities support a range of logistics needs. We can schedule pre-arranged shipments, drop-ship products to multiple locations, maintain reserve stock, and monitor consumption to recommend optimal shipping dates. This comprehensive approach ensures that clients receive the right products with the right support for their operational needs.

Expert Guidance in Selecting Seals

AC&M’s century of experience ensures clients receive expert guidance tailored to their needs. We help organizations across government, utilities, transportation, military, and commercial sectors select the right seal for cargo integrity, infrastructure protection, or supply chain security, including specialized solutions like container seals. Our team knows how different seal types, plastic, metal, cable, and bolt, fit various operational environments, providing practical solutions backed by ISO‑9001 standards.

Support extends beyond product selection. AC&M experts advise on seal application, inspection, and program design, helping organizations streamline security, reduce risks, and ensure consistent performance. Staying up-to-date with the latest technologies and global standards, we act as a trusted partner who enhances both security and operational efficiency.

We also provide guidance on customization options such as numbering, color coding, and ID marking to meet regulatory requirements and operational preferences. This ensures every seal not only performs its security function, but also aligns with an organization’s workflow, making audits, inspections, and inventory management more efficient. Our expertise transforms standard sealing solutions into a comprehensive security program tailored to each client.
