Magnesium

· Magnesium is lightweight yet strong, commonly used in aerospace and automotive sectors where weight reduction is crucial. Its machinability allows for complex shapes, and it is also used in various electronic devices due to its excellent conductivity.

Titanium

· Titanium is a strong and lightweight metal, ideal for aerospace and medical implants. Its corrosion resistance and biocompatibility make it promising for harsh environments, and its high strength-to-weight ratio suits various industrial applications.

Tool Steel

· Tool steel is a high-hardness, wear-resistant, and high-heat-strength alloy steel specially used for manufacturing tools. It is widely applied in molds, cutting tools, stamping dies, and precision mechanical parts. Tool steel can be categorized into cold work, hot work, and high-speed tool steels based on its application.

Alloy Steel

· Alloy steel is made by adding one or more alloying elements (such as chromium, nickel, molybdenum) to carbon steel to enhance its strength, toughness, wear resistance, and corrosion resistance. It is widely used in structural components, machinery parts, gears, and high-strength bolts, suitable for high loads and harsh environments.

Surface Treatment

Surface treatment processes that meet diverse application needs

Anodizing

An electrochemical process that forms a dense oxide film on the surface of aluminum or titanium alloys, classified into Type II (decorative, thickness 4-25μm) and Type III (hard, thickness up to 125μm).

Treatment Colors: Supports dyeing in transparent, black, gold, red, blue, and more, with diverse color options.

Effects Description: Enhances corrosion resistance, hardness, and wear resistance; the surface is smooth and non-conductive. Type III is suitable for high-strength applications (e.g., aerospace), while Type II is mainly for decorative purposes.

Electroplating

Deposits a layer of other metals (such as chromium, nickel, copper, gold, etc.) on the metal surface to enhance functionality or aesthetics.

Treatment Colors: Chrome (silver-white), nickel (silver-white), copper (pink/gold), tin-cobalt (light rose), copper-tin alloy (pink/gold/silver-white).

Effects Description: Improves corrosion resistance, conductivity, or magnetism; the surface is smooth and can be multilayered. Tin-cobalt alloy is suitable for complex parts, while copper-tin alloy provides both decoration and protection.

Sandblasting (Shot Peening)

Forms a matte or satin finish by high-speed jetting glass beads or corundum, a mechanical treatment.

Treatment Colors: Maintains the original color of the substrate; requires subsequent treatments (e.g., anodizing) for color effects.

Effects Description: Removes tool marks and burrs, increases surface roughness or uniform texture, purely visual improvement without chemical protection.

Powder Coating

Electrostatically sprays dry powder and cures at high temperatures to form a protective layer, compatible with all metals.

Treatment Colors: Supports various color customizations with strong coverage.

Effects Description: Wear-resistant and impact-resistant, suitable for outdoor or military equipment, but the coating is thick (18-72μm), which may affect tolerances.

Passivation

Removes iron impurities through acid pickling (nitric acid/citric acid) to form a chromium/nickel protective layer, mainly for stainless steel.

Treatment Colors: Maintains the original color of the metal or slight discoloration, no dyeing function.

Effects Description: Rust-proof, improves cleanliness, suitable for medical and food equipment, does not add thickness.

Chemical Nickel Plating

Deposits a nickel-phosphorus alloy layer on the surface through a chemical reduction reaction, providing uniform coverage on complex structures.

Treatment Colors: Silver-white, hardness can be adjusted through heat treatment.

Effects Description: High hardness and wear resistance, suitable for precision parts (e.g., medical devices), but cost is relatively high.

PTFE Coating

Coats with Teflon material to form a non-stick, low-friction surface, suitable for high-temperature environments.

Treatment Colors: Mostly black or gray, limited color choices.

Effects Description: Resistant to chemical corrosion, good insulation, but durability is lower than other coatings, and cost is higher.

Polishing

Mechanical or chemical grinding to achieve a mirror-like smooth surface, commonly used on stainless steel, aluminum, and brass.

Treatment Colors: Retains the original metal color, enhances gloss.

Effects Description: Improves aesthetics, reduces friction, but labor-intensive and difficult for complex geometries.

Oxidation Coloring

Applies color through dyeing or electrolytic processes after anodizing, specifically for aluminum.

Treatment Colors: Customizable in various colors (e.g., antique bronze, gold, blue), vibrant hues.

Effects Description: Combines the protective and decorative qualities of anodizing, suitable for lighting fixtures and electronic product casings.

Painting/Spray Coating

Sprays liquid coatings that cure to simulate anodizing effects, suitable for metals and plastics.

Treatment Colors: Realistic colors that can mimic metal textures.

Effects Description: Scratch-resistant and colorfast, but requires high-temperature curing, and plastic parts may deform.

Machining Processing

Three-Axis Machining Center

A three-axis machining center is a common high-precision CNC milling machine where the table and spindle move in X, Y, and Z directions, enabling efficient machining of flat and three-dimensional profiles.

Basic operations include face milling, drilling, tapping, chamfering, and slotting; suitable for parts requiring high precision in hole positions or profile control; high machining accuracy and good repeatability, ideal for mass production.

Four-Axis Machining Center

A four-axis machining center adds a rotational axis to the three-axis design, allowing the workpiece to rotate automatically for multi-surface machining, improving precision and efficiency.

Can perform all three-axis operations while facilitating multi-surface machining; suitable for parts that require drilling, tapping, and milling on multiple faces; flexible programming adapts to complex shapes or irregular parts.

CNC Lathe

A CNC lathe is a high-precision machine used for machining rotating parts, where the tool moves in the X-axis (radial) and Z-axis (axial) direction, completing automatic turning processes through program control.

Suitable for batch processing of shafts, rings, and sleeves; capable of machining diameters up to φ500mm and lengths within 800mm.
