Melt Bolt Thermocouple

Shanghai Zhaohui Pressure Apparatus Co., Ltd. is one of the leading manufacturers and suppliers of melt bolt thermocouple in China, also supports customized service and 1 year warranty. Welcome to wholesale bulk durable melt bolt thermocouple in stock here from our factory.

A melt bolt thermocouple is a specialized temperature sensor designed for direct immersion in molten polymers, plastics, or viscous fluids during extrusion and injection molding processes. Its rugged bolt-style housing enables easy installation through adapter fittings or thermo wells, providing reliable, real-time melt temperature measurement at the nozzle or barrel. The melt temperature thermocouple typically uses grounded or ungrounded junction types with fast response times, ensuring accurate process control. Constructed from corrosion-resistant alloys, the melt bolt thermocouple withstands high pressures, abrasive flow, and temperatures up to 400°C or more. Optional integral transmitters offer 4–20 mA outputs for remote monitoring. Proper installation depth and thermal contact are critical for repeatability. Regular calibration verifies accuracy. These thermo couples are essential for product quality, energy efficiency, and equipment protection in continuous polymer production lines.

Serving plastics, rubber, and polymer processing industries including extrusion, injection molding, blow molding, and film production. Also used in compounding, recycling, and hot-melt adhesive manufacturing where direct molten material temperature sensing is essential for quality and efficiency.

Rugged bolt-style housing for direct immersion, fast thermal response, corrosion-resistant alloys, high-pressure tolerance up to 400°C, grounded or ungrounded junctions, easy adapter installation, and reliable real-time sensing in abrasive polymer flows, tip customization option and OEM service available.
