Injection molding relies on precise temperature control to produce high-quality plastic parts, and hot runner systems are at the heart of this process. Hot runner connector (also known as heavy-duty connector) plays a key role in ensuring that these systems operate reliably under extreme conditions. This article will explain their applications and advantages.
What is a Hot Runner Connector?
A hot runner connector is a specialized heavy duty electrical component designed to deliver power, signals, and data within hot runner systems. These connectors link heaters, thermocouples, and control units, maintaining consistent heat distribution across the mold.
Applications in Hot Runner Systems
Power supply for heaters
Temperature Control
Sensor Integration
Data Communication
Key Advantages of Heavy Duty Connectors in Hot-Runner Systems
1. Extreme Temperature Resistance
Operate continuously at 200°C–250°C near heaters.
UL 94 V-0 rated housings prevent melting or deformation.
2. Sealed Against Contaminants
IP675/IP68 protection resists dust, humidity, water, or other fluids such as cleaning and cooling agents, oil, etc.
Silicone gaskets maintain sealing at high temperatures.
3. Stable Electrical Performance
Gold-plated contacts minimize resistance drift.
EMI shielding (360°coverage) protects low-voltage signals.
4. Mechanical Durability
1,000+ mating cycles with stainless steel locking levers.
Vibration-proof design for press-side mounting.
