Surface Finishes
Metal and Plastic
As Machined
Standard finish, surface roughness of 3.2 μm (126 μin), removes sharp edges and deburs parts cleanly.
Sand Blasting
Powerfully propels blast media against surfaces to remove coatings and impurities.
Tumbling
Utilizes barrel or vibratory processes with abrasives to smooth and polish the surface of parts.
Electropolish
Electrochemical process that smoothens, polishes, and deburrs metal surfaces to a high gloss.
Heat Treatment
Alters the physical (and sometimes chemical) properties of a material to achieve desired mechanical properties.
Alodine
Chemical treatment process providing corrosion protection and surface preparation for paint adhesion.
Anodizing
Electrochemical process that forms a durable, corrosion-resistant oxide layer on the surface of metals.
Teflon Coating
Applies a protective layer of PTFE to reduce friction and enhance corrosion resistance.
Black Oxidize
Chemical bath that creates a black oxide coating on metal to improve corrosion resistance.
Electroless Plating
Deposition of a metal coating on substrates using an autocatalytic chemical process.
Electroplating
Uses electric current to reduce dissolved metal cations to form a coherent metal coating.
Painting
Application of paint for aesthetic improvements and protective coatings.
Passivation
Chemical treatment to enhance the corrosion resistance of metals by removing free iron from the surface.
Powder Coating
Dry finishing process using powdered paint to provide a high-quality, durable finish.
Electrophoresis
Coating process using charged particles suspended in a solvent, typically for uniform finishes.
Brushed Finish
Mechanical polishing that produces a unidirectional satin finish.
SPI Finish
SPI Finish standardizes surface textures on plastic parts, offering finishes from high-gloss to matte, ensuring consistent aesthetics and functionality in injection molding.
