Thermocouple

Most of the hot runner injection molding molds are provided with surrounding circulating water cooling pipes to control the mold base temperature, and the high-speed circulating water will cause conti

Vacuum magnesium oxide filling is the basic method to determine the internal insulation performance, anti-drift ability and service life of armored thermocouples. At present, there are two major produ

Thermocouple extension wire outer jacket is the outermost protective covering of internal alloy wires and shielding braiding. With long term exposure to high temperature radiation, chemical corrosion,

Many injection molding workshops store spare thermocouples at random in tool cabinets, ground storage boxes or near hot runner maintenance stations. Ignoring improper storage environments will cause b

In rush shift replacements, operators typically confuse the positive and negative poles of the thermocouple due to poor workshop lighting, faded wire color markers and damaged plug terminals. Reverse

Portable reference contact thermometers are the primary tools for onsite testing of hot runner thermocouple accuracy. Most workshops do not perform the periodic calibration and daily maintenance of th

During the long term high temperature operation of hot runner thermocouple measuring heads, constant accumulation of carbonized plastic residues in form of dense carbon layers blocking the heat conduc

The mold trial run phase is a period with high incidence of thermocouple overheating burnout damage, which is mainly caused by excessive setup of process parameters, wiring errors, and uncalibrated co

The outer insulation layer of thermocouple extension wires is subject to long-term high temperature radiation, chemical corrosion, bending friction near hot runner molds, etc., the service life of the

In most hot runner shops, the real-time thermocouple temperature readings are used for on-site process adjustment, while ignoring the huge historical temperature fluctuation data kept by the controlle

Persistent mechanical vibration from high speed injection machines, stack mold clamping movement and frequent ejection cycles slowly degrades thermocouple assemblies, resulting in drifting resistance,

Hot runner temperature control systems are divided into independent single zone thermocouple controller and multi-zone integrated mainframe controller with different signal processing performance, col
