El proceso de estampado en frío es uno de los nuevos procesos de mecanizado a presión de menor o ningún corte
metal. Es un método de transformación que utiliza la deformación plástica del metal bajo la acción de
fuerzas externas y, con ayuda de moldes, redistribuye y transfiere el volumen de metal para formar
las piezas o formatos necesarios. El proceso de estampación en frío es el más adecuado para producir piezas estándar.
elementos de fijación como pernos, tornillos, tuercas, remaches, pasadores, etc.
Here’s a structured overall description of pernos de seguridad 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
-
Resistencia a la corrosión: Yellow chromate layer enhances protection against rust.
-
High Visibility: Bright yellow color aids quick inspection in machinery or aerospace applications.
-
Durabilidad: Withstands harsh environments (e.g., automotive, marine, or aerospace).
4. Applications
-
Aeroespacial: Engine components, landing gear.
-
Automoción: High-vibration areas (e.g., race cars, motorcycles).
-
Maquinaria industrial: 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
-
Resistencia a las vibraciones: Prevents bolt loosening.
-
Chemical Protection: Electroplating shields against oxidation.
-
Color Coding: Yellow may indicate specific torque or maintenance requirements.
7. Limitations
-
Sensibilidad a la 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.

10. Common Specifications
-
Thread Standards: UNC/UNF, METRIC.
-
Grades: Class 8.8, 10.9 (steel); A2/A4 (stainless).
