CNC Machining Service

● Heating the workpiece to a high temperature and then rapidly cooling it, typically using water, oil, or air. This treatment is primarily used to increase hardness and wear resistance.

● Applications: Tool steel, bearings, gears, etc

Tempering

● After quenching, the workpiece is reheated to a lower temperature and slowly cooled to relieve internal stresses and reduce brittleness, improving toughness.

● Applications: Tools, molds, automotive parts, etc

Annealing

● Heating the metal to a specific temperature and then cooling it slowly to reduce hardness, improve ductility, and relieve internal stress.

● Applications: Aluminum alloys, copper alloys, etc.

Normalizing

● Heating the workpiece to a specific temperature and then cooling it in air, used to refine the grain structure, increase strength, and improve hardness.

● Applications: Low alloy steel, carbon steel, etc.

Surface Hardening

● Hardening the surface of the workpiece while maintaining a softer core, improving wear resistance without compromising toughness.

● Applications: Gears, shafts, etc

● Depositing a layer of zinc onto steel or iron to prevent corrosion.

● Applications: Automotive parts, appliances, building materials, etc

Chromium Plating

● A layer of chromium is plated onto the surface to enhance wear resistance, hardness, and corrosion resistance.

● Applications: Automotive parts, machine components, tools, etc

Gold/Silver Plating

● Gold or silver is plated on the surface for enhanced appearance and electrical conductivity, commonly used for decorative and electronic components.

● Applications: Electronics, jewelry, etc

Copper Plating

● A copper layer is plated onto the surface, often to improve conductivity.

● Applications: Electrical components, wiring, circuit boards, etc.

Powdered coating material is sprayed onto the workpiece surface and then heated to form a durable, protective layer. This method is often used for corrosion resistance and aesthetics.

Applications: Household appliances, automotive parts, furniture, etc

Painting

Liquid paint is sprayed onto the workpiece surface to provide an even color coating and protective layer.

Applications: Automotive, furniture, appliance exteriors, etc

Thermal Spraying

Metal, ceramic, or polymer powders are heated to high temperatures and sprayed onto the workpiece surface to form a coating.

Applications: Aerospace, energy, molds, etc

Metal layers are deposited on the workpiece surface through a chemical reaction, rather than using electricity. This is used for surface enhancement and corrosion resistance.

• Applications: Electronics, automotive, aerospace, etc.

Oxidation

Anodized

Oxidation reactions are used to form an oxide layer on the surface of metals, enhancing corrosion resistance and durability.

• Aluminum Anodized: Used to form a hard, corrosion-resistant oxide layer on aluminum alloys.
• Black Oxidation: Forms a black oxide layer on steel parts to improve corrosion resistance.
• Applications: Automotive parts, electronics housings, aerospace components, etc.

Black Oxidation

Phosphating

Forms a phosphate coating on the surface to improve corrosion resistance and adhesion for subsequent coatings or paints.

• Applications: Automotive parts, household appliances, etc.

Nitriding

Nitrogen is introduced into the surface of steel, forming a hard nitrided layer that improves surface hardness, wear resistance, and fatigue strength.

• Applications: Molds, tools, automotive components, etc.

● Using abrasives such as sandpaper or polishing cloth to smooth the surface of metals and remove oxidation, improving surface gloss.

● Applications: Decorative parts, appliances, instruments, etc. 

Mirror Polishing

● Fine mechanical polishing to achieve a mirror-like finish, commonly used for high-appearance parts.

● Applications: Stainless steel products, decorative components, etc. 

Electrolytic Polishing

● Using an electrolytic solution to dissolve material from the workpiece surface, improving smoothness and enhancing its appearance.

● Applications: Medical instruments, food processing equipment, electronics, etc.

● Using a flame to melt metallic powder, which is then sprayed onto the workpiece to create a hard coating.

● Applications: Engine components, turbine blades, etc.

Plasma Spraying

● Using a plasma arc to melt coating materials, which are then sprayed onto the surface to form a strong, durable coating.

● Applications: High-temperature alloys, corrosion-resistant coatings, molds, etc.

● A vacuum process in which metal or ceramic films are deposited onto the workpiece surface, enhancing wear resistance, hardness, and corrosion resistance.

● Applications: Cutting tools, molds, decorative parts, etc.

CVD (Chemical Vapor Deposition)

● A chemical process where vaporized chemicals react on the workpiece surface, forming a solid coating that provides high performance under extreme conditions.

● Applications: Semiconductors, aerospace components, tools, etc.

● A high-energy laser beam is used to rapidly heat the surface of the workpiece, followed by cooling to form a hardened layer, often used to increase wear resistance.

● Applications: Molds, tools, mechanical components, etc.

Laser Cladding

● Laser is used to melt both the surface of the workpiece and a cladding material, forming a bonded coating to improve wear, corrosion, or heat resistance.

● Applications: Wear parts, mechanical components, etc.
