O processo de encabeçamento a frio é um dos novos processos para a maquinagem sob pressão com menos ou nenhum corte
metal. É um método de processamento que utiliza a deformação plástica do metal sob a ação de
forças externas e, com a ajuda de moldes, redistribui e transfere o volume de metal para formar
as peças ou os espaços em branco necessários. O processo de encabeçamento a frio é o mais adequado para a produção de
elementos de fixação, tais como cavilhas, parafusos, porcas, rebites, cavilhas, etc.

Here’s a structured overall description of safety wire bolts 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
  • Resistência à corrosão: Yellow chromate layer enhances protection against rust.

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

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

4. Applications
  • Aeroespacial: Engine components, landing gear.

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

  • Máquinas industriais: 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
  • Resistência à vibração: Prevents bolt loosening.

  • Chemical Protection: Electroplating shields against oxidation.

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

7. Limitations
  • Sensibilidade à temperatura: 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).
