Overview
Non-standard titanium hangers are specialized fixtures used in industrial surface treatment processes such as electroplating and anodizing. Unlike standard hangers, these are custom-designed to hold specific parts during chemical baths, ensuring proper electrical contact and part orientation. Titanium is the preferred material due to its exceptional corrosion resistance in acidic and alkaline environments. These hangers are typically fabricated from commercially pure titanium (Grade 1 or Grade 2) which offers optimal conductivity while resisting degradation from repeated exposure to processing chemicals.
Structure and Working Principle
A non-standard titanium hanger consists of a main frame, contact points, and part-specific holding features. The frame provides structural support while the contact points ensure electrical connectivity to the power supply. Custom hooks, clips, or baskets are designed to securely hold workpieces without masking critical surfaces. During operation, the hanger serves as both a physical support and electrical conductor. Current flows from the power source through the titanium structure to the parts being treated, enabling uniform deposition or oxidation. The open design allows for proper chemical circulation while maintaining part positioning throughout the process.
Key Features
The most notable feature of non-standard titanium hangers is their complete corrosion resistance in harsh chemical environments. Unlike steel or copper alternatives, titanium won't contaminate plating baths or degrade over time. These hangers offer excellent strength-to-weight ratio, allowing for larger fixtures without excessive weight. Titanium's natural oxide layer provides inherent passivation, ensuring consistent electrical performance. Custom designs can incorporate spring-loaded contacts, adjustable elements, or specialized coatings to enhance functionality for specific applications.
Application Areas
Non-standard titanium hangers are primarily used in metal finishing industries including decorative plating, functional coatings, and protective surface treatments. They're essential for aerospace components, medical implants, and precision engineering parts where exact positioning is critical. These fixtures also find use in semiconductor manufacturing for wafer processing, and in the production of automotive components where high-volume plating with consistent quality is required. Any application involving aggressive chemicals or requiring repeatable, precise part handling benefits from custom titanium hangers.
Maintenance and Precautions
Proper maintenance of titanium hangers involves regular inspection for mechanical damage and thorough cleaning between uses. While titanium resists chemical attack, accumulated plating deposits can affect performance and should be removed. Avoid exceeding the hanger's designed load capacity as this can lead to permanent deformation. When not in use, store hangers in a dry environment to prevent contamination. Periodic checks of electrical contact points are recommended to ensure consistent plating quality.
B2B Procurement Guide
When sourcing non-standard titanium hangers, provide suppliers with detailed part drawings and processing parameters. Lead times for custom fixtures typically range from 2-6 weeks depending on complexity. Consider working with manufacturers who offer design assistance and prototyping services. For reference, small simple hangers may cost around $50-$100 while large, complex designs can exceed $500. Volume discounts often apply for repeat orders of identical fixtures. Verify material certifications and request samples when establishing new supplier relationships.
