Mid-Atlantic Rubber Inc
CNC Machining & Custom Metal Fabrication
Precision Machined and Fabricated Parts in Metal and Plastic. One Shop. Full Capability.
CNC Machining & Custom Metal Fabrication
When your project calls for machined or fabricated metal and plastic components, you need a shop that combines precision equipment with real manufacturing experience. At Mid-Atlantic Rubber (MAR), our CNC machining and custom fabrication capabilities give you access to milled, turned, and fabricated parts produced to tight tolerances from a wide range of metals and engineering plastics.
What sets MAR apart is that CNC machining is just one part of a much larger manufacturing operation. We also run water jets, lasers, tube cutters, and injection molding equipment in the same facility. That means when your project requires both machined metal components and cut gaskets, molded seals, or fabricated enclosures, everything comes from one shop. One point of contact. One quality standard. One shipment.
Our CNC & Fabrication Equipment
MAR’s machine shop is equipped with CNC mills and supporting fabrication equipment capable of handling a broad range of part sizes, geometries, and materials. Our equipment lineup includes:
CNC Milling Centers
Multi-axis CNC mills for producing complex 3D geometries, pockets, slots, holes, and precision surfaces in metals and plastics.
Water Jet Cutting
For flat metal profiles, plate cutting, and parts that benefit from a cold-cutting process with no heat-affected zone. Handles material up to 8 inches thick.
Laser Cutting
Tube Laser Cutting

Case Study
Machined Aluminum Housings and Matching Gaskets for an Aerospace Sensor Manufacturer
Client Name
Apex Avionics Group
Industry
Aerospace
Location
Manassas, VA
The Challenge
Apex Avionics Group designs and assembles environmental sensor modules for commercial and military aircraft. Each module consists of a precision-machined aluminum housing, internal mounting brackets, and a set of silicone gaskets that seal the housing against moisture, dust, and pressure changes at altitude.
Apex had been sourcing these components from two separate suppliers: a machine shop in Maryland for the aluminum housings and brackets, and a gasket supplier in Pennsylvania for the silicone seals. The arrangement worked, but it created ongoing coordination problems. Dimensional inconsistencies between the two suppliers meant that roughly 12% of gasket sets didn’t seat properly in the machined housings. That led to rework on the assembly line, delayed deliveries, and increased inspection costs. When Apex needed an engineering change, they had to coordinate revisions with both vendors independently, which added weeks to every design iteration.
Their engineering manager wanted one vendor who could produce both the machined housings and the matching gaskets, ensuring dimensional consistency and eliminating the coordination overhead.
The MAR Solution
Apex found MAR through a recommendation from a fellow aerospace subcontractor in Virginia. After reviewing the part drawings and assembly requirements, our team proposed taking over both the machined components and the gaskets as a single program.
Here’s how we structured the work:
CNC-machined housings
CNC-machined brackets
Water jet-cut gaskets
Kitted shipments
We delivered first article samples within two weeks. Apex’s quality team inspected and approved them on the first submission with no dimensional deviations outside of tolerance.
The Results
After 12 months of running the consolidated program with MAR, Apex saw clear improvements across the board:
12% to 0.5%
2 Vendors to 1
3 Weeks Faster
Beyond the quality and lead time gains, Apex appreciated the simplicity of receiving complete, kitted assemblies ready for their production floor. Their purchasing team went from managing two vendor relationships, two sets of POs, and two incoming inspections down to one. That freed up time they redirected toward new product development.
“The biggest win wasn’t just better parts. It was knowing that the gaskets and housings were made from the same model, in the same shop, by people who understand how they fit together. We stopped finding problems at assembly and started focusing on building product.”
