In today’s rapidly evolving electronics industry, the demand for high-performance, miniaturized, and durable connectors is greater than ever. At the heart of producing these components is one key element: the connector mould. The quality of the mould directly impacts the precision, stability, and lifespan of the connector, which in turn affects the reliability of everything from smartphones to EVs and industrial systems.
At Hongxin, we specialize in the design and manufacturing of custom connector moulds tailored for high-efficiency production, consistent output, and long tool life. With decades of industry expertise and cutting-edge CNC and EDM technology, we deliver mould solutions that meet the exacting standards of global electronics manufacturers.
What is a Connector Mould?
A connector mould is a precision-engineered tool used to shape the plastic or metal housing and internal features of electrical connectors. These connectors can range from USB ports and power plugs to complex multi-pin interfaces used in automotive or data center applications.
Typical connector moulds include:
-
Single cavity & multi-cavity designs
-
High-speed connector moulds
-
Overmolding and insert moulds
-
Micro-precision connector core & cavity inserts
Why High-Quality Connector Moulds Matter
1. Micro-Level Accuracy
Connectors often have intricate internal structures, tiny pins, and tight tolerances. A slight defect in the mould can lead to poor fit, electrical failure, or signal loss. Hongxin ensures micron-level accuracy using high-speed CNC and fine EDM processing.
2. Material Compatibility
Whether you’re working with glass-filled nylon, LCP, or PBT, our connector moulds are engineered for thermal stability and dimensional control during high-volume injection molding.
3. Cycle Time Optimization
Our moulds are designed with advanced cooling systems and optimized parting lines to reduce cycle time, minimize warpage, and maintain consistent output — critical for mass production.
4. Durability & Maintenance
We use hardened tool steel (like H13, S136) and offer surface treatments such as nitriding or PVD coatings to extend mould lifespan. Modular design also ensures easy maintenance and part replacement.
Connector Mould Applications
Hongxin’s connector moulds are widely used in:
-
