CNC Turning Services

Huili offers metal surface finishing services for guaranteed machine accuracy, surface smoothness, and corrosion resistance. Some of these services include:

• This service uses paints of various colors to create the desired appearance of the product. It also forms a protective layer that prevents corrosion and damage from chemicals or elements in the environment.
• Heat Treatment. This service offers a wide range of thermal treatment options, including tempering, hardening, annealing, normalizing, and stress-relieving. It helps with improving the hardness and wear resistance levels while at the same time balancing better ductility and toughness.
• Sand Blasting. This service is used to produce a roughened surface on the metal part by blasting it with glass beads or other abrasive material. It can be used to remove coatings and paint, which provides improved adhesion for new coats of paint or other coating materials.
• Laser Marking. This process uses lasers or bright lights to mark the product. It can be used to produce visible marks, copy a machine-readable code, or etch characters onto the surface of the metal part.
• Acid Etching. This service provides an even coloration and uniformity across all cases because it does not require masks as other processes such as engraving and stamping do.
• This process is used to remove any residual contaminants from the metal part by exposing it to an alkaline solution. It ensures better adhesion of primer and paint coatings, which extends the life of these materials.
• This service uses chemical or electrochemical methods to deposit a metal on the CNC turning part. Electroplating is used for decorative purposes, corrosion prevention, and wear resistance purposes.
• The anodizing process is used to create a porous surface that ensures improved adhesion of oil and paint on the metal part. It also forms an electrically insulating layer that prevents corrosion and increases resistance to chemical reactions.
• Chrome Plating. This service provides greater protection against corrosion and wears due to its shiny, reflective nature. However, it is not commonly used on metal parts because it requires expensive equipment, materials, and chemicals.
• Powder Coating. This service provides a protective layer that is resistant to chemicals, weathering, and abrasion. It has high humidity resistance since the particles are thermally fused. It creates a finish that is tougher than your conventional paint. However, it is not suitable for metal parts with small or intricate details because it can spread through these gaps. It is ideal for bicycle parts, household appliances, drum hardware, automobile, and other aluminum extrusions.
• Black Oxide. This service is used to produce a matte black color on the metal part that offers protection from oxidation and corrosion. It can even be used on stainless steel, cast iron, and other metals with low carbon content.
