Case Study: Precision Metal, Plastic, and Silicone Components for Optical Connectivity Systems

Project Background

A Europe-based industrial connectivity and optical interconnect solutions provider required a long-term manufacturing partner capable of producing high-precision metal, plastic, and silicone components for use in fiber-optic and MT-based connector systems.

The customer faced several challenges:

Tight dimensional tolerances for MT ferrule–related components
Mixed-material production (metal, plastic, and silicone) under one supply chain
Stable quality for high-volume production
Reliable export capability for global deployment

INTERTECH was selected as the manufacturing partner due to our integrated tooling, injection molding, metal processing capabilities, and proven OEM experience.

Manufactured Components Overview

Precision Metal Components

INTERTECH manufactured a range of metal parts used for mechanical fixation, electromagnetic shielding, and structural stability within optical connector assemblies.

Ferrule Fixation & Clamping Components

Metal ferrule fixation
MT ferrule fixation
Ferrule clamp
Metal ferrule clamp
MT ferrule clamp
OBT MT ferrule clamp

These components require high concentricity, consistent clamping force, and surface integrity, ensuring precise fiber alignment and long-term mechanical reliability.

EMI Shielding Components

EMI plate (100 μm)
EMI shielding spring
EMI shielding plate
Housing EMI shielding plate

Manufacturing Challenges & INTERTECH Solutions

1. Multi-Material Integration

The project required metal stamping/machining, plastic injection molding, and silicone molding under one coordinated production system.
INTERTECH reduced supply chain complexity by managing all processes internally.

2. Tight Tolerance & Quality Stability

Ferrule-related components demand micron-level consistency.
Our engineering team implemented process control, tooling optimization, and in-process inspection to ensure repeatable quality across production batches.

3. Export-Ready Production

All components were produced with export compliance, traceability, and packaging control, supporting smooth international logistics.
