Vacuum Impregnation

Vacuum impregnation sealing at Magna-Tech Manufacturing is most effective on porous substrates such as metal castings and powdered metal components required to meet pressure retention specifications, or to improve machinability or finish quality of the part. Candidates for impregnation include parts manufactured to contain gases or liquids and parts that will be plated or coated with a surface finish. Parts can be impregnated in the as-cast or in the machined state.

Electronic Components Division

Vacuum impregnation sealing provided by the electronic components division of Magna Tech is effective for wire harnesses, terminated connectors, thermistors, over-molded coil windings, and insert and injection mold components that are exposed to harsh environmental conditions. The sealing process ensures part integrity. There is no change in the appearance or dimensional attributes of the components.

Rust and Corrosion Removal Services

Magna-Tech Manufacturing offers processes to remove rust and corrosion from ferrous materials. Production parts that cannot be used, or may be considered scrap due to corrosion, are candidates for Magna-Tech’s de-rusting services.

Thermal De-Burr

Magna-Tech Manufacturing provides Thermal Deburring services for applications that typically have inaccessible burrs such as internal and external flashing burrs, rough edge finishes and applications that have threaded holes.

Chromate Conversion Coatings

Magna-Tech Manufacturing offers Iridite Conversion Coating, also known as Chromate Conversion Coatings. Conversion Coating is conductive and is designed to improve corrosion resistance for unpainted aluminum surfaces as well as increase adhesion of paint finish for aluminum and aluminum alloys.

Patriot CNC

When you are looking for an industry-best solution for your machining needs, look no further than Patriot CNC.

From transportation to aerospace to oilrelated industries, Patriot delivers! On time, on budget, to your specifications and to the highest standards in the industry.

Heat Treating Services

During casting, at least some of the hardening atoms remain in solution. If the part is elevated in temperature, the rate of nucleation and growth of these precipitates can be accelerated. This treatment is called artificial aging (T5) and improves strength through precipitate hardening. Some T5 treatments are performed for the purposes of stabilization rather than improving strength.

Ultrasonic Cleaning

Magna-tech provides ultrasonic cleaning services to optimize the removal of soils from certain parts. Cleaning occurs when high frequency bursts of ultrasonic energy are applied to a heated liquid cleaning solution that surrounds the parts. This energy produces a three-dimensional wave pattern of alternating positive and negative pressure areas within a cleaning tank. The alternating pattern creates bubbles during periods of negative pressure and implodes them during periods of positive pressure in a phenomenon known as “cavitation.” The implosion creates a microjet action that penetrates and cleans areas impossible to reach with brushes, sprays or dips.

Dunnage Washing

Shipping containers often become contaminated from repeated use or from machining oils and other debris. Magna-Tech provides dunnage washing services to clean these contaminants from shipping materials. We utilize a fully automated system to provide fast and cost-effective service.
