What are some common brands of hot runner temperature sensors

Most of the well-known brands of hot runner temperature sensors are used in industrial automation, measurement and control, and plastic injection molding. These sensors are very accurate, stable over time, and respond quickly. They also work well in harsh manufacturing situations where they are exposed to high temperatures, vibrations, and corrosive conditions. The following brands are well-known and widely used around the world. They are roughly sorted by their technical strength, level of innovation, and reputation in the industry. Leading international names like Husky, Mold-Masters, Synventive, Günther, Watlow, Athena Controls, PCS Company, and DME dominate with their advanced thermocouple designs and integrated solutions. Reliable options from Yudo, INCOE, and HRSflow also have a strong market presence and are widely used by professionals.

I. Well-Known Brands Around the World


OMRON is a well-known Japanese brand of automation control. Its hot runner temperature control cards and matching sensors are notable for being able to control temperatures with an accuracy of ±0.08℃. They use imported high-precision thermocouple elements and are designed to resist electromagnetic interference, which makes them great for precision injection molding applications like creating car parts and electrical components.

Kistler is a high-end Swiss sensor maker. Its 4004A micro melt pressure and temperature sensor can directly monitor temperatures up to 350°C and pressures up to 2500 bar in hot runners. It has a front-end diameter of only 3mm, so it can fit into small nozzles. It is commonly used in intelligent molds and medical-grade injection molding production.

Honeywell, a large American company, makes high-stability platinum resistance thermometers (PT100) and thermocouples that are great at controlling drift over time. These are often used in aerospace and energy areas where it is very important to be able to repeat temperatures.

TE Connectivity, a top global manufacturer of sensor solutions, makes armored thermocouples just for hot runner systems. These thermocouples are very resistant to vibration and corrosion, may be indexed and packaged in a variety of ways, and are commonly used in complex mold systems with several cavities.

Texas Instruments (TI) doesn't make sensor probes directly, but its analog signal conditioning chips are widely used in hot runner temperature control modules to make temperature measurement signals more accurate and less sensitive to noise. These chips are a key part of high-end temperature control systems.

II. Top Brands in the US

HGTECH is a high-tech company with ties to colleges in China. It uses its experience with lasers and sensors to make high-response thermistors that work well with hot runner systems. These parts have their own intellectual property rights and have already been made in large quantities and sent to some domestic makers of injection molding machines.

For more than 20 years, Changzhou Huibang Electronics Co., Ltd. has been working on the research and development of temperature control devices. Its hot runner temperature control cards use a self-developed PID algorithm and high-precision sensors that it makes itself to control the temperature with an accuracy of ±0.1℃. We make everything in the production chain ourselves, which guarantees stability and consistency.

Suzhou Huichuan Technology Co., Ltd. is one of the best companies in China that sells automation solutions. Its hot runner temperature management systems include smart diagnostic features that allow for online sensor status monitoring and early notification of faults. This helps to improve intelligent manufacturing.

III. Sensor Makers Who Are Professionals

SHIBAURA: A Japanese company that has been making thermistors for a long time. Its NTC sensors, which are protected by glass, provide particular benefits for controlling hot runners at low temperatures.

TKS is a well-known Taiwanese brand of circuit protection parts that offers complete solutions for detecting and protecting against high temperatures.

Huanya and Subote are domestic suppliers of thermocouple probes. They sell inexpensive K-type and J-type hot runner-specific temperature sensors that work with most temperature control equipment.
