What parts use surface finishing techniques
The standard finish of any part is the basic cosmetic appearance of the part immediately it is manufactured. It refers to the state of the part when ejected, machined, printed, or cast. This finish will have visible tooling marks, resin, or powder remnants as applicable to the production method.
CNC Machined Parts
CNC machined parts require surface treatment to enhance corrosion resistance, improve wear resistance, and achieve a polished aesthetic. Treatments like anodizing, plating, or powder coating protect against environmental damage, reduce friction, and extend lifespan, ensuring precision components perform reliably in demanding applications, such as aerospace or automotive industries.
Rapid Tooling Parts
Rapid tooling benefits from surface treatments to increase durability and reduce wear during high-speed production. Coatings like nitriding or chrome plating minimize friction, improve mold release, and enhance surface hardness. This ensures consistent quality, prolongs tool life, and maintains precision for prototyping or short-run manufacturing processes.
3D-printed Parts
3D-printed parts often have rough surfaces, requiring treatments like sanding, coating, or chemical smoothing to improve finish and strength. Surface treatments enhance resistance to moisture, UV, and chemicals, while also improving aesthetics. This ensures parts meet functional and visual standards for applications like medical devices or consumer products.
Die-casted Parts
Die-casted parts need surface treatment to prevent corrosion, enhance durability, and improve appearance. Processes like electroplating or powder coating add protective layers, increase hardness, and ensure smooth finishes. This is critical for high-volume components used in automotive or electronics, where performance and visual appeal are essential.
Sheet Metal Fabrications
Sheet metal fabrications require surface treatments to protect against rust, improve paint adhesion, and enhance durability. Galvanizing, powder coating, or anodizing create barriers against environmental factors, ensuring longevity in applications like construction or HVAC systems, while also providing a professional, aesthetically pleasing finish.
Extruded Parts
Extruded parts, often made from aluminum or plastics, need surface treatments like anodizing or powder coating to boost corrosion resistance and surface hardness. These treatments also enhance aesthetic appeal and improve wear resistance, making extrusions suitable for architectural, automotive, or industrial uses where durability and finish are critical.
