冷镦加工是一种少切削或无切削的压力加工新工艺
金屬。它是一種利用金屬在下列因素作用下產生塑性變形的加工方法
外力作用下，在模具的幫助下，重新分配和轉移金屬的體積，以形成
所需的零件或坯料。冷镦工艺最适合生产标准的
螺栓、螺絲、螺帽、鉚釘和銷等緊固件

Here’s a structured overall description of 安全線螺栓 with yellow electroplating:

1. Definition & Purpose

• Safety Wire Bolts: Fasteners designed with holes or notches to allow the threading of safety wire, preventing loosening due to vibration or rotation.

• Yellow Electroplating: A surface treatment providing corrosion resistance, aesthetic appeal, and visibility (often for identification or safety marking).

2. Electroplating Process (Yellow)

• Base Material: Typically steel, stainless steel, or titanium.

• Plating Layer:

  • Undercoat: Often zinc or cadmium electroplating for corrosion resistance.

  • Topcoat: Yellow chromate conversion coating (for zinc) or yellow dye/paint (e.g., zinc-nickel alloy with yellow passivation).

• Standards: Compliant with ASTM B633 (zinc plating), MIL-DTL-45204 (cadmium), or AMS 2468 (yellow chromate).

• Safety Wire Bolt electroplating yellow

3. Key Features

• 耐腐蝕性: Yellow chromate layer enhances protection against rust.

• High Visibility: Bright yellow color aids quick inspection in machinery or aerospace applications.

• 耐用性: Withstands harsh environments (e.g., automotive, marine, or aerospace).

4. Applications

• 航太: Engine components, landing gear.

• 汽車: High-vibration areas (e.g., race cars, motorcycles).

• 工業機械: Critical bolted joints subject to dynamic loads.

5. Safety Wire Compatibility

• Pre-drilled holes or wire grooves accommodate stainless steel safety wire (e.g., 0.032″ diameter).

• Wire wrapping follows ANSI/MSNAS standards to ensure secure locking.

• Safety Wire Bolt electroplating yellow

6. Advantages

• 抗震性: Prevents bolt loosening.

• Chemical Protection: Electroplating shields against oxidation.

• Color Coding: Yellow may indicate specific torque or maintenance requirements.

7. Limitations

• 溫度敏感性: Some yellow dyes degrade at high temps (>250°C).

• Wear: Plating may wear off under friction; lubricants or additional coatings (e.g., PTFE) can help.

8. Compliance & Certifications

• ASTM/SAE: Standards for plating thickness/adhesion.

• RoHS/REACH: Compliance for hazardous substance restrictions.

9. Maintenance

• Regular inspections for plating wear or wire integrity.

• Avoid abrasive cleaners to preserve the yellow finish.

• Safety Wire Bolt electroplating yellow

10. Common Specifications

• Thread Standards: UNC/UNF, METRIC.

• Grades: Class 8.8, 10.9 (steel); A2/A4 (stainless).
