Markets We Serve

Aerospace OEM

OEM stands for 'Original Equipment Manufacturer' in aerospace. In the aerospace OEM context, the acronym refers to companies that design and manufacture the original components or systems used in aircraft assembly. These manufacturers are responsible for developing parts such as engines, avionics, landing gear, and other critical systems that contribute to the overall performance and safety of the aircraft.

The aerospace market contributes billions of pounds to the global economy each year, and this process begins with the design, manufacture and assembly of aircraft by the Original Equipment Manufacturer (OEM).

Silmid continues to deliver a wide variety of products approved by major OEMs such as Airbus and Boeing, with a growing portfolio designed to meet changing demands and newer generation aircraft. Partnering with key brands such as AeroShell, PPG Aerospace, 3M, Eastman and many more, we hold large stock volumes to support OEM aerospace companies and their evolving requirements.

Why Silmid for OEM supply? We support production continuity through stockholding across key consumable categories, including lubricants, sealants, structural adhesives, and surface preparation solutions. Our team can also help buyers identify the right product for the application and process, supporting efficient specification and repeat ordering.

OEM Approved Sealants for Aerospace OEM Applications

Sealants are essential in aerospace OEM build and assembly because they support long-term protection, reliable sealing performance, and consistent build quality.

They are commonly used across fuel tank sealing and structural sealing areas such as access panels, seams, and environmental sealing points.

Silmid supports OEM aerospace companies with stocked sealant options from trusted aerospace brands, helping teams source the right approved materials for the application and repeat ordering needs.

Assembly and Anti-Seize Lubricants

Assembly and anti-seize lubricants help aerospace OEM production teams improve process consistency by protecting interfaces, reducing galling risk, and supporting controlled installation during build.

These products are commonly used on threaded fasteners, fitted components, and assembly points exposed to load, heat, or harsh environments.

Silmid holds stock across key aerospace lubricant ranges, supporting procurement teams with dependable supply and simplified repeat ordering for ongoing assembly requirements.

Critical Cleaning for Aerospace OEM Manufacturing

Critical cleaning supports aerospace OEM build and assembly outcomes by ensuring surfaces are prepared properly for bonding and sealing, which helps improve process reliability and consistency.

Cleaning and surface prep are commonly required before applying adhesives, sealants, coatings, or lubricants to remove oils, residues, and other contaminants.

Silmid provides a range of cleaning and removal solutions to help teams select the right option for their process and maintain dependable supply for ongoing production needs.  

Structural Adhesives for Aerospace OEM Manufacturing

Structural adhesives support aerospace OEM manufacturing by improving joint strength and rigidity, and helping reduce rework through consistent bonding outcomes.

They are commonly used to bond composite and metal substrates in aircraft manufacturing processes where mechanical fastening alone is not sufficient.

Silmid supplies a broad range of structural adhesives, with strong availability across leading brands to support specification, production continuity, and repeat ordering.

FAQ: Aerospace OEM

What does OEM mean in aerospace?

OEM stands for Original Equipment Manufacturer. In aerospace, OEMs are the organisations that design and manufacture aircraft and the original systems and components used during aircraft build and assembly.

What is the significance of the OEM market in aviation?

The aerospace OEM market is where aircraft programmes begin. Decisions made during OEM design and manufacturing influence safety, performance, and long-term reliability. OEM production also drives demand for approved materials and consumables used across build and assembly processes.

Why are approvals and quality assurance important for aerospace OEM applications?

Aerospace OEM applications often require materials that align with manufacturer approvals and expected performance in demanding environments. Using the right approved product helps teams maintain consistent outcomes, reduce rework, and support internal review processes using the available product and safety documentation.

How can suppliers support OEM aerospace companies with sourcing and repeat ordering?

Suppliers can support OEM aerospace companies by holding stock across key consumable categories, helping teams identify the right product for specific processes, and maintaining dependable fulfillment. This helps reduce delays, supports production continuity, and simplifies repeat ordering for ongoing requirements.
