Surface finish

Item	Description	Materials	Color	Texture
Anodizing	Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used are 2 types:type II anodizing(coating thickness: 12-18μm for black, 8-12μm for clear, and 4-8μm for color) and type III anodizing(hard anodizing, provides excellent corrosion and wear resistance).	Aluminum	Clear, black, grey, red, blue, gold.	Smooth, matte finish.
Powder Coating	Powder coating applied as a free-flowing, dry powder and works as a thin layer of protective polymer on the surface of the part.Unlike conventional liquid paint , powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light.	Aluminum, Stainless Steel, Steel	Black, any RAL code or Pantone number	Gloss or semi-gloss
Electroplating	involves coating a metal part with a very thin layer of another metal or metal alloy, in order to protect from corrosion and oxidation of the base part or to change its cosmetic appearance. Tin, Nickel, Zinc (galvanizing), and Chrome are all common plating metals.	Aluminum, steel, stainless steel	n/a	Smooth, glossy finish
Brushing	Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes.	ABS, Aluminum, Brass, Stainless Steel, Steel	n/a	satin
Polishing	Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection.	PC,PMMA,Aluminum, Brass, Stainless Steel, Steel	n/a	Glossy
Printing & Etching	You can choose silk screening,pad printing or laser etching for different structures ,silk screening can be used for larger surfaces and when mixing multiple colors for even more complex graphics; pad printing can be used for printing on curved surfaces; laser etching is ideal for making precise and permanent marks on metal and some plastics.	Aluminum, Brass, Stainless Steel, Steel	n/a	n/a

Common Post Processing

The easiest way to source your custom parts, with 15+ surface finishing options. Get your parts bead blasted, anodized, or powder coated.

Machined Finish

Machined parts will exhibit tool marks that align with the cutting path. The machined finish is smooth, achieved directly from the machine without additional polishing. Minimal handwork is required to remove any burrs, allowing the parts to be promptly finished and delivered soon after machining.

Blasting

Bead blasting achieves a consistent matte finish on machined parts, effectively eliminating tool and sandpaper marks. This process involves directing a high-pressure stream of abrasive material against a surface to smooth rough textures, roughen smooth surfaces, or remove surface contaminants. Key process parameters include air pressure and the size of glass beads used. Glass beads are available in various sizes ranging from #80 to #220.

Anodizing

Anodizing is an electrochemical process that enhances the surface of metals, typically aluminum, to increase durability, corrosion resistance, and aesthetics. During anodizing, the metal part is immersed in an electrolyte bath and subjected to an electric current. This process forms a protective oxide layer on the metal’s surface, which can be further enhanced with dyes or sealants to achieve different colors and finishes. Anodizing is widely used in industries where protection and aesthetics are crucial, such as automotive, aerospace, and architectural applications.

Painting

Painting is a finishing process where a coating of paint or protective layer is applied to the surface of an object or part. This process not only enhances the appearance of the object but also provides protection against corrosion, wear, and environmental factors.
There are various painting techniques and types of paints used depending on the material of the object, its intended use, and the desired finish. Common methods include spray painting, which uses compressed air to atomize and apply paint evenly, and powder coating, where electrostatically charged powder is applied and then cured under heat to form a hard finish.
Painting is essential in industries ranging from automotive and consumer goods to industrial equipment and aerospace, where both aesthetic appeal and functional durability are crucial.

Frequently Asked Questions

To provide clarity on our services, here are responses to commonly asked questions about prototyping and manufacturing.

How much does metal CNC machining cost?

The pricing for metal CNC machining hinges on several factors: the intricacy and dimensions of the part, as well as the specific metal employed. These variables impact the choice of machinery, production time, and raw material expenses.
Our approach leverages machine learning algorithms to precisely compute costs for any machinable part directly from CAD files, drawing from extensive data derived from millions of CNC machining orders we’ve handled in the past. Upload your CAD file today to instantly receive a customized quote for CNC machining.

How do I get a manufacturing quote?

Besten offers instant pricing and lead time estimates for your custom parts. You have two convenient options to receive a quote and Design for Manufacturing (DFM) feedback from our dedicated sales team:

Upload your 3D CAD file(s) directly on our Get a Quote page.
Email your 3D CAD file(s) to info@bestencnc.com.
Our commitment ensures that in most cases, you will receive a quotation within 24 business hours of submitting your RFQ. Should there be any delay, we will promptly notify you to keep you informed.

What file formats are supported for instant quotes?

For quoting purposes, Besten prefers 3D CAD files in formats such as STEP, IGES, X_T, or STL. For 2D CAD drawings, please provide them in DWG or PDF format with reference dimensions included. Please note that all Besten processes rely on high-quality 3D CAD solid models for accurate quoting and production.

How can I be assured that my design will remain confidential? (Non-Disclosure Agreements)?

At Besten, we uphold our reputation built on handling hundreds of thousands of unique designs over many years, ensuring strict confidentiality of customer information through our established factory policies. For added assurance, we are ready to sign Non-Disclosure Agreements (NDAs) upon request from customers who require this level of documentation.

How does Besten guarantee the quality of my parts?

At Besten, we prioritize addressing our customers’ quality concerns right from the outset. We provide practical and cost-effective advice spanning design, materials, production processes, and manufacturability during initial communications.
