  • Low Machining Cost: Due to its excellent physical properties, aluminum alloy is easy to be machined, and the aluminum machining can be cheap cost effectively.
  • Fast Machining Timing: Fast machining speed that bring fast machining timing to satisfy fast delivery requirement.

Steel is a material that is used in various industries, and it is also an important metal material for CNC milling.

There are many types of steel, but the most commonly used steel in the industry is carbon steel. Carbon steel has a lower cost and can be machined easily. It can also be welded and bent to shape, which makes it easy to fabricate. Carbon steel is also corrosion resistant, so it’s much easier to maintain than other types of metal.

The brass material is the most common material for cnc machining. It is a copper-zinc alloy that contains between 60 and 90% copper, with the remainder consisting of zinc. Brass is a metal made from two different types of metal: copper and zinc.

Brass is also used in some alloys, such as bronze and brass steel.

It has been used for centuries and it has many uses in everyday life, like coins, door handles and doorknobs. It can be made into pipes for water supply systems or gas lines for heating systems.

Titanium is a material that has been used for the purpose of making cnc machining and cnc milling tools. This is because titanium is a very hard material. It can be used for making tools that are used for cutting harder materials like steel, aluminum, and stainless steel.

It is also an expensive material to work with as it costs around $1,000 per pound in order to purchase it from the seller. But there are many benefits to using titanium as it can be used in both the medical industry as well as aerospace industries.

Surface Finishing:

Here is a list of standard surface finishes. For custom surface finishes such as electroplating or polishing.


The As-machined surface is the surface of a machined object that has been ground to its final form.

There are two types of as-machined surfaces: the as-turned surface and the as-ground surface.

The as-turned surface is created when a turner turns a bar into a cylindrical shape. The as-ground surface is created when an engineer grinds a flat, square or hexagonal bar into its final form.


Our standard finish is “as machined” finish. It has a surface roughness of 3.2 μm (126 μin). All sharp edges are removed and parts are deburred. Tool marks are visible.

Bead blasting is a surface treatment process that removes material from a metal, glass, or plastic surface. It is used to remove paint, rust, and corrosion from the surface. The process is also known as bead-blasting or bead blasting.

The process of bead blasting involves propelling beads at high velocity against a hard surface in order to remove material from the surface. The beads are propelled with compressed air through a nozzle called an air gun. The air gun can be used with different nozzles for different applications and can be fitted with an abrasive nozzle for more aggressive abrasion


Anodizing is an electrolytic passivation process that grows the natural oxide layer on aluminum parts for protection from wear and corrosion, as well as for cosmetic effects. and corrosion, as well as for cosmetic effects.


Anodizing is a process that converts the surface of an aluminum alloy into a dense, hard, and wear-resistant oxide coating.

This process is done by immersing the aluminum part into an electrolyte solution heated to about 85 degrees Celsius. The electricity from an electric current is applied to create this oxide layer on the surface of the metal.

The Anodizing Process:

1) The metal object is cleaned and etched 

2) It is immersed in an electrolyte solution heated to about 85 degrees Celsius 

3) Electricity is applied from an electric current to create this oxide layer on the surface of the metal

Electroplating is a technique that uses electric current to reduce dissolved metal ions in water to produce a thin layer of metal on an electrically conductive surface. It is used to provide a decorative, protective, or functional coating to items such as jewelry, coins, cutlery and other household items.

Electroplating is one of the most important industrial processes for producing a variety of metal parts that would be difficult or uneconomical to manufacture by other methods. The technique has been known for centuries and was probably first applied in the second half of the nineteenth century.

Polishing is the process of smoothing a surface by abrading it with an abrasive material.

Polishing is a common finishing process for metals, and other hard materials such as stone, plastics, and composites.

It may also be used to remove oxidation from metal surfaces. The finish may be either matte or glossy.

Polishing is often done by machine, but can also be done by hand using an abrasive pad or a polishing cloth.

Powder coating is a process that is used to provide a tough, durable and sustainable finish on metal products. It can be applied by dipping the metal object in a powder or spraying it with the powder.

Powder coating is popular for its durability, which makes it suitable for outdoor use. It also provides a range of colors and finishes without requiring any additional surface preparation.

brushing finishing

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.

Painting is a visual art form in which colors are applied to a surface (usually canvas) and allowed to dry. The application of the paint can be by hand, or it can be done mechanically. The process of applying the paint has been called painting since medieval times, but this term is not very accurate because it includes other methods such as drawing, printmaking and sculpture.

Black oxide is a conversion coating similar to Alodine that is used for steel and stainless steel. It is used mainly for appearance and for mild corrosion resistance.

Chromate conversion coating, more commonly known by its brand name Alodine, is a chemical coating that passivate and protects aluminum from corrosion. It is also used as a base layer before priming and painting parts.

New Product Development

The new product development processes including of part drawing, sample, trial run production, mass production, we need to co-operate step by step:

Our engineer designers working with your product team to complete product design to create CAD/3D drawings based on your concept design sketch, sample, picture etc.

A prototype sample is essential step to review your custom water bottle design concept, then make drawing modification to complete final product drawing before invest big money for  high-volume production or custom toolings.

All unique design parts which need to make custom tooling, it’s a big money investment and related to product quality in mass production, working with a professional and reliable supplier can save your money also timing, some information you must know before start tooling manufacturing process:

  1. tooling material
  2. tooling cavity
  3. tooling lead time
  4. tooling analysis report
  5. tooling structure 
  6. tooling cost
  7. product unit cost (details)

First time samples FAI report from supplier is must, and require enough samples from supplier to do inspection and test to work out issue list, discuss with supplier to solve all issues and require second time samples to do inspection & test again until all is good before place an order.

A trial-run production order is necessary before you place big volume order, because some problems may not be found at the sample evaluation process, a trial run production could help to find all issues during production and fix these issues without big lost.

Finally you are happy with the product quality and services from the supplier, it’s time to work out the mass production order quantity, confirm the production lead time, product shipment cost & lead time, customs duty tax cost, then start to issue PO to supplier for mass production.
