Introduction
Off-the-shelf connectors are suitable for many applications — but not all.
In industries such as aerospace, defense, medical devices, and high-speed telecommunications, every connection counts. These sectors often require connectors that can handle unique geometries, tight tolerances, or harsh operating conditions.
That’s where custom connector pin and socket design becomes essential.
At AVF Decolletage, we don’t just manufacture components — we engineer connectivity solutions. Each custom pin or socket is designed to meet a specific mechanical, electrical, or environmental challenge, ensuring unmatched performance and reliability.

Why Custom Connector Pins and Sockets?
Every industry faces unique performance and compliance requirements. A standard design might meet the basic fit, but not the functional precision needed.
Here’s where customization makes the difference:
⚙️ 1. Application-Specific Geometry
Custom shapes allow for optimized mating pressure, insertion depth, and locking retention.
AVF Decolletage engineers socket and pin designs to improve signal transfer while preventing deformation or wear over repeated cycles.
2. Tailored Materials for Function
We select materials that balance strength, conductivity, and corrosion resistance:
-
Brass alloys (C36000, C17300, C54400) – high electrical performance and machinability.
-
Stainless steels (303, 316, 416) – for structural strength and durability.
-
Aluminum (6061, 2017) – for lightweight or aerospace-grade connectors.
3. Custom Plating for Every Environment
Plating isn’t cosmetic — it defines performance.
We partner with qualified suppliers in Singapore and the USA to provide:
-
Gold plating – for conductivity and corrosion resistance.
-
Nickel plating – for wear and temperature stability.
-
Tin plating – for cost-effective protection and solderability.
4. Industry-Specific Compliance
Our custom designs ensure compliance with:
-
ISO 9001:2015 quality standards.
-
Aerospace and defense specifications (AS, MIL, DFARS).
-
Medical-grade traceability and REACH/RoHS compliance.
How AVF Decolletage Develops Custom Designs
Our strength lies in collaboration. We partner with customers from concept to production to ensure every design performs perfectly from the start.
1. Engineering Consultation
We begin by analyzing your technical drawings, mating assemblies, and electrical requirements. Our engineers then provide design feedback for manufacturability and cost optimization.
2. Rapid Prototyping & Validation
Using Swiss CNC & CAM machining, we deliver prototype samples in days — not weeks. These samples undergo fit, insertion force, plating adhesion, and signal continuity tests to confirm real-world functionality.
3. Production Scaling
Once validated, designs transition seamlessly to full production using automated Swiss-type CNC lines with ±0.005 mm tolerances and real-time SPC monitoring.
4. Inspection & Documentation
Our ISO-certified quality system provides full traceability, dimensional reports, and plating certificates for every batch.

Custom Connector Design in Action
✈ Aerospace & Defense
Lightweight, gold-plated brass pins for avionics systems that endure extreme vibration and temperature shifts.
Medical Devices
Miniature sockets with smooth, burr-free finishes for sterilizable diagnostic and surgical instruments.
Telecommunications & 5G
High-frequency sockets and RF pins engineered for GHz-level signal integrity and minimal contact resistance.
⚡ Automotive & EV Systems
Custom hybrid connectors combining power and signal contacts for electric drive and sensor modules.
Marine & Renewable Energy
Corrosion-resistant stainless-steel connectors for underwater sensors and offshore equipment.
Each solution reflects the same philosophy — no two applications are identical, and neither should be the connectors that power them.
Why Partner with AVF Decolletage?
