Precision CNC Machining

Auto lathe parts

Automatic lathe machining is a lathe with a mechanically automated controlled cutting process. It has high performance, high precision, and low noise. Suitable for the processing of material cooper, aluminum, steel, and plastic. The wide application of automatic lathe saves labor and high-volume production.

CNC(computer numerical control) turning is a machining process a cutting tool with a single cutting edge used to remove material from a rotating workpiece to generate a cylindrical shape. Suitable to processing copper, aluminum, steel and plastic, and so on. The processing is stable and efficient which is widely used for mass production for some turned parts. CNC turning is a highly-skilled, high-precision engineering process.

CNC milling is a machining process the cutting tool rotates to bring cutting edges to bear against the workpiece. The milling cutter often with multiple cutting points. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations. It is one of the most commonly used processes for machining custom parts to precise tolerances.

Aluminum Die Casting/Cooper Die Casting/Zinc Die Casting/Steel Die Casting
Die casting is a precision casting method. The dimensional tolerances by die casting are very small, and the surface accuracy is very high. In most cases, die castings can be assembled and applied without machining again. Parts with thread can also be cast directly. From small parts such as general camera parts, typewriter parts, electronic computing devices, and decorations, as well as complex parts of vehicles such as automobiles, locomotives, and airplanes, most of them are manufactured by the die-casting method.
The most common aluminum for die casting is A383, A380. For Zinc material, we can make hinges, locks and motorcycle parts and etc. Cooper material is also widely used for medical devices, communication devices and motorcycle parts, and so on. We also do surface treatment including CNC machining, heat treatment, sandblasting, powder coating, etc. We have the high technical force and can also machine the part after die casting to make it more precise for assembling.
  1. The surface of the castings is smooth.
  2. Good casting performance, it can die-cast precision parts with complex shapes and thin walls
  3. Surface treatment: electroplating, spraying, painting, polishing, grinding, etc.
  4. High output


  1. A higher MOQ can save cost.
  2. Materials choice is limited.
  3. The porosity of die casting parts.

Stamping is an efficient production method. Using compound dies, especially multi-station progressive dies, multiple stamping processes can be completed on one press, and the whole process from strip uncoiling, leveling, punching to forming and finishing can be achieved. Automatic production. The production efficiency is high, the working conditions are good, and the production cost is low. Generally, hundreds of pieces can be produced per minute. Stamping is very widely used processing for many parts, such as car body, chassis, fuel tank, radiator fins, container shells, motors and household appliances, and so on.

 1. Stamping is a processing method with high production efficiency and low material consumption. Easy to operation
2. No need for another machining process again and with high accuracy.
3.Stamping parts have better interchangeability. Stability of stamping process is better, the same batch of stamping parts. Can be used interchangeably without affecting assembly and product performance.
4. Stamping processing can obtain parts with high strength, high rigidity, and lightweight.
5. Low cost and high production
6. Stamping can produce parts with complex shapes that are difficult to process by other metal processing methods.

Плазменная резка/лазерная резка/гибка/сварка

Sheet metal is a comprehensive cold working process for metal sheets (usually below 6mm), including shearing, punching/cutting/compounding, folding, riveting, splicing, forming, etc. Its notable feature is the uniform thickness of the same part. There are many different metals that can be made into sheet metal, such as aluminum, brass, copper, steel, tin, nickel and titanium. We can supply the service for all these materials. Sheet metal is widely used, such as automobile and truck bodies, airplane fuselages and wings, medical tables, roofs for buildings, and many other applications. Our sheet metal service included plasma cutting/laser cutting, bending, welding, and surface treatment.

Впрыскивание пластмассы

Injection molding is mainly used to process and produce some plastic parts. At a certain temperature, the completely melted plastic material is stirred by a screw, injected into the mold cavity with high pressure, cooled, and solidified to obtain a molded product. This method is suitable for the mass production of parts with complex shapes and is one of the important processing methods. With the advantages of fast production speed, high efficiency, automatic operation, various design types, simple shape, small size, accurate product size, convenient product update, complex shape, etc.

Surface Treatment

During the machining process, surface treatment is also a very important process. This process will directly influence what we look at the parts. The surface treatment is always for beautifying the machining parts surface and also protect the parts from damages in a special use environment. Huili Precision can do most of the surface treatment, like polishing, brushing, sandblasting, anodizing, powder coating, painting, silk printing and laser engraving and so on.
