Our Surface Finishing Specifications

Part surfacing finishing techniques can either be for functional or aesthetic purposes. Each technique has requirements, such as materials, color, texture, and price. Below are the specifications of the plastic finishing techniques rendered by us.

Bead Blasting

Bead blasting is the process of powerfully propelling, generally with high pressure, a stream of blast media against a surface to remove unwanted coating layers and surface impurities. Can choose Aluminum, Steel, Stainless Steel, Brass, Copper etc. processing.


Electroplated coating preserves the surface of parts and resists rusts and other defects from causing decay by applying electric currents to reduce metal cations. Can choose Aluminum, steel, stainless steel etc. processing.

CNC Machining Overview

What’s CNC Machining?

CNC Machining, or Computer Numerical Control Machining, is a manufacturing technique where computer-controlled devices are used to remove layers from a material, creating detailed parts or components. Through a combination of tooling and precise machine movement, it produces parts to exact specifications.

What’s the CNC Machining Process?

The CNC machining process begins by designing a part in CAD software. This design is then converted into a set of machine commands using CAM software. The CNC machine reads these commands to precisely cut and shape the material, producing a finished part that matches the digital design.

Why Choose CNC Machining?

CNC Machining offers unparalleled precision and repeatability, making it a top choice for industries requiring intricate parts. Its ability to handle a variety of materials, from metals to plastics, combined with fast production times and consistent quality, makes it an essential method in modern manufacturing.

What’s the Difference Between 3D Printing and CNC Machining?

3D printing is an additive manufacturing method, building parts by depositing material layer by layer. In contrast, CNC machining is a subtractive method, starting with a solid block of material and removing sections until the desired part is achieved. While 3D printing is often favored for complex geometries and rapid prototyping, CNC machining excels in durability, precision, and material versatility.

What are your maximum dimensions for CNC machining?

AL Aluminum is proficient in facilitating the production and prototyping of large machined parts, be it metal or plastic. We boast a substantial CNC machining build envelope measuring 2000 mm x 1500 mm x 300 mm. This ensures we can accommodate even sizable parts, including those tailored for furniture or architectural applications.

Absolutely! The exact tolerance we offer is contingent upon your specific requirements. For CNC machining, our metal components adhere to the ISO 2768-m standards, while our plastic parts align with ISO 2768-c standards. It’s worth noting that the demand for higher precision will correspondingly increase the cost.

Of course! AL Aluminum has the capability to produce upwards of 10,000 diverse prototypes on a monthly basis, spanning from simple to intricate designs. Our infrastructure is bolstered by 120 state-of-the-art CNC machines, and we pride ourselves on having a team of over 100 skilled technical experts.

AL Aluminum caters to both one-off prototype and large-scale production runs. Thus, there is typically no strict MOQ. Whether you need a single part or thousands, AL Aluminum aims to provide a solution.

Lead times can vary based on the complexity of the design, the chosen material, and the current workload at AL Aluminum. However, one of the advantages of CNC machining is its speed, especially for simpler parts. Once the setup is complete, machining times can be relatively quick. Parts delivered as fast as 1 day! But for an accurate estimate, it’s best to request for quotes directly.
