OEM finishing is an important part of the production process for manufacturers that need consistent protection, appearance, and performance across finished components. A reliable finishing partner must do more than apply a coating. The process must integrate with production requirements, meet specifications, and deliver repeatable results across recurring orders.
Rhinehart Finishing provides OEM finishing services for manufacturers across demanding industrial markets. As a family-owned company with an ISO 9001:2015-certified quality management system, we provide the equipment, processes, and quality controls needed to support ongoing OEM production.
OEM Metal Finishing Methods and Capabilities
Our OEM metal finishing capabilities extend from pretreatment through coating, detailing, and inspection. Conveyorized and batch systems provide flexibility for different component sizes, geometries, production volumes, and finishing requirements.
Powder Coating
Powder coating uses an electrostatic process to apply charged powder particles to a prepared surface. The coating is then oven-cured to create a hard, continuous finish. This process provides fabricated metal components with consistent coverage and resistance to corrosion, abrasion, chemicals, and regular handling.
Liquid Spray Painting
Liquid spray painting provides additional flexibility when coating requirements, part geometry, substrate, or finish specifications call for a wet-applied system. Rhinehart uses environmentally controlled spray capabilities and offers color matching to help manufacturers achieve required performance and appearance standards.
Pretreatment and Military-Grade Coatings
Effective OEM finishing begins with proper surface preparation. Rhinehart offers zinc phosphate pretreatment certified to TT-C-490 Type I to support coating adhesion and corrosion resistance. We also provide CARC to MIL-DTL-53039 and MIL-DTL-64159, along with other military-spec coatings. Rhinehart is ITAR registered.
Part Identification, Masking, and Detailing
OEM components may require more than a standard coating. Rhinehart provides custom masking to protect specified surfaces and assembly areas, along with stamping, stenciling, silk screening, character filling, and other detailing capabilities. These services can support identification, branding, assembly, and customer-specific requirements.
When Is OEM Finishing Used?
OEM finishing solutions can be incorporated after stamping, welding, machining, fabrication, or other manufacturing processes and before final assembly or shipment. Rhinehart finishes components for heavy truck, construction equipment, agriculture, military and defense, and other industrial applications.
How Rhinehart Customizes OEM Finishing Solutions
Each project begins with the component and its requirements. Part size, geometry, substrate, end-use environment, drawings, tolerances, coating specifications, masking needs, production volume, and applicable standards can all influence the finishing plan.
Rhinehart coordinates pretreatment, coating, application, detailing, and inspection requirements around these factors. Production schedules and recurring orders can also be considered to help OEM finishing services fit efficiently into the customer’s broader manufacturing workflow.
Supporting Consistent OEM Production
Repeatability is essential when the same components are produced across multiple runs. Controlled processes help maintain coating quality, appearance, and performance while reducing variation that can create problems later in production.
Rhinehart can also coordinate detailing, assembly, packaging, and transportation when required. Our integrated fabrication-to-finishing workflow with sister company Rhinehart Development further helps manufacturers reduce vendor handoffs and simplify production by bringing complementary manufacturing and finishing capabilities together.
Why Choose Rhinehart Finishing for OEM Finishing?
Rhinehart operates a 100,000-square-foot production facility with conveyorized coating systems, large-part capabilities, and an in-house quality testing lab. Our ISO 9001:2015 certification, TACOM certifications for zinc phosphate and combat-grade powder, and in-house testing support OEM finishing where consistent quality and documented processes matter.
