What Thermocouple Differences Exist Between European and Asian Hot Runner Brands?

Global hot runner brands from Europe, North America, and Asia adopt different thermocouple standards, designs, and specifications. European brands such as HASCO, DME, and EWIKON follow strict DIN standards, using grounded MI thermocouples with standardized connectors. North American brands like Mold-Masters and Synventive emphasize durability and anti-interference performance. Asian leaders including YUDO focus on compact design, fast response, and cost-effective compatibility. Differences appear in sheath material, cable length, connector type, and calibration methods. Understanding these variations is essential for correct replacement and maintenance. Many molds use mixed-brand components, requiring cross-compatible thermocouples. This article compares thermocouple design, standards, and application characteristics among major regional hot runner brands, helping users select compatible replacement parts.
