Achieve Precision, Performance and Aesthetics with Strategic Metal Surface Finishing
From aerospace alloys to industrial components, metallic parts demand rigorous quality control. However, metal finishing elevates build quality to the next level through specialized surface treatments. This guide explores how partnering with experts in metal surface finishing services optimizes functionality, properties and appearance of CNC-machined metals.
An Introduction to Metal Finishing Processes
Metal finishing techniques prepare metallic surfaces for harsh operating environments or critical specifications through various physical and chemical metal finishing processes. Services enhance properties like corrosion/wear resistance, hardness, cleanliness and aesthetics post-machining operations.
Outsourcing to a full-service finisher unlocks sophisticated technologies along with process expertise previously difficult to develop independently at desired quality levels and turnaround times.
Evaluating a Finishing Provider's Capabilities
Consider these factors when selecting a trusted partner:
Treatment Technologies
Inspect plating, passivation, anodizing, thermal spray, paint booths and more.
Quality Management
ISO-9001 shows commitment to defect-free, on-spec treatments meeting industry certs.
Materials Experience
See examples of finishing specialized alloys like stainless, titanium or inconel.
Secondary Processes
Services like polishing, buffing, testing complement primary surface enhancements.
Turnaround Times
Evaluate throughputs for rapid prototyping or high-volume production needs.
Leveraging Core Metal Finishing Processes
Top service providers deliver techniques like:
Plating
Hard chrome, nickel, titanium coatings protect against wear and corrosion.
Anodizing
Aluminum anodizing increases durability and provides customizable colors.
Passivation
Chemical treatments enhance stainless steel's corrosion resistance qualities.
Ceramic Coatings
Thermal sprayed alumina-titania provides low-friction hardness up to 98%.
Painting
Powder, wet paint or e-coats ensure functional and matching custom metallic colors.
Industries Leveraging Metal Finishing Expertise
Given properties enhancements, key sectors include:
Aerospace
Corrosion prevention on airframe alloys extends asset lifetimes.
Oil & Gas
Harsh offshore treatments withstand corrosion in rig environments.
Medical
Sterilizable finishes meet biocompatibility for implants and tools.
