we should consider and pay attention to many questions,such as hot runner system refuelling problem ,hot runner system color changing.
Therefore,get to know the hot runner mould notice will help us successful apply hot runner mould technology.
A good hot runner system color changing solution is very necessary for a plastic products manufacturer.
hot runner system color change process is refer to new material directly pushing out all stranded materials
in the runner and whole move forward. So it’s easy to clean . In contrary,if new material viscosity is lower the
material is easy to run into the stranded materials center and separate the stranded material is step by step.
Therefore,hot runner system color change process is more trouble.
If stranded material viscosity is much more sensitive for temperature.
In operation,worker can appropriate rise the temperature to reduce viscosity in order to speed up hot runner system color changing.

traditional mould and hot runner mould



Hot runner mould is so widely used at present, mainly because it has the incomparable virtues than the traditional mold:
1, expanding the scope of the injection molding process application.
Many advanced plastic forming technology is developed based on hot runner technology.
2, save the plastic materials.
In pure hot runner mold because there is no cold runner, so there is no waste.
This is especially important significance for reduce raw material costs.
In fact, the main international hot runner manufacturers have the violent development in the period of the oil and the raw plastic material are expensive.
Because of hot runner technology can reduce the waste is an effective way to reduce the cost of raw materials;

3, eliminate the follow-up process, be helpful for production automation.
Parts after molding mould of hot flow path is the finished product, do not need to trim the gate and recycling processing cold runner and other processes. Be helpful for production automation;
4 shorten the molding cycle.
Because there is no limit to the gating system, cooling time, the plastic products after curingcan be out in a timely manner.Many hot runner used thin-wall parts the molding cycle time can be under 5 seconds.
5, reduce the waste, improve product quality.
In the process of hot runner molding, plastic melt temperature in the runner system was controlled accurately. Plastic can flow uniform state of each cavity, so as to produce consistent parts.
In addition, the gate of hot runner molding parts are of good quality and low residual stress after demoulding, deformation small.
So a lot of high quality products on the market are manufactured by hot runner mould.

Thermocouple installation requirements


Thermocouple installation requirements

Thermocouple is a temperature measurer that common used in temperature measurement instrument. Thermocouple is directly measure temperature and convert temperature signals into thermoelectric emfs signal. Thermocouple working principle is ease,but we should notice thermocouple installation requirements.
Thermocouple installation requirements is accurate temperature measurement,safety examination and convenient maintenance. In the same time,thermocouple installation required that don’t affect the equipment operation and production operations. To meet the above requirements,in selection of thermocouple of the installation and insertion depth,we should pay attention to the following points:

  1. In order to make the measurement end of thermocouple has sufficient heat exchange between the measured medium. We should choose a reasonable measuring location and try to avoid installing in the valve,elbow and pipe.


German heating elements
  1. With a protection casting thermocouple has function of heat transfer and heat loss . In order to reduce the measurement error.thermocouple should have insert in enough depth.
  • For measurement of pipeline center fluid temperature,we generally inserted thermocouple measurement end into pipe center. Just for a example,if measured fluid pipe diameter is 200mm,the thermocouple should be inserted depth should choose 100mm.
  • For high temperature and high pressure and high velocity of temperature measurement (such as main steam temperature). In order to reduce cases of fluid resistance and protection to prevent break under the action of the fluid. We can use hot thermocouple or shallow insert thermocouple. Shallow insert temperature protection tube,its depth into the steam pipe should be no less than 75mm; hot set standard thermocouple insert depth is 100 mm.

Thermocouple installation requirements is thermocouple measurement end insert in a certain depth.Anole hot runner is a professional hot runner manufacturer in China.We use GC&HOTSET heating elements and we are the agent of GC&HOTSET.

hot runner thermocouple


 Thermocouple is one of the most commonly used temperature detecting element in industry, the working principle of the thermocouple are two different components of conductor on both ends of the connection circuit, such as two different connection end temperature, then produce thermoelectric potential physical phenomena within the loop.
The hot runner thermocouple have below advantage:
1.high measurement precision.
2.Because of thermocouple directly contact with the object which is being measured, so not 3.affected by the medium .
4.the thermocouple measuring range is very widely.
The commonly used thermocouple can measure the temperature range from - 50 ~ + 1600 ℃, some special thermocouple minimum measurable to - 269 ℃ (e.g., gold iron nickel chrome), up to + 2800 ℃
5. simple structure, easy to use.
Thermocouple is usually composed of two different kinds of metal wire, and is not limited by the size and the beginning, the outside has protective casing, which are very convenient.

hot runner thernocouple

The basic principle of thermocouple temperature measurement
Welding the conduct of semi-conductor A&B together,form a closed loop.
When conductor A and B presisstent points 1and 2 and the temperature is different ,so the electromootive force happen,this kind of phenomenon called the thermoelectric effect.Thermocouple is in using this effect to work.
The kinds of thermocouple
Commonly used thermocouple can be divided into two categories, thermocouple and non standard thermocouples.

hot runner system classification


 hot runner system classification


There have two ways of hot runner system classification.One type is classified by heating ways.
This type has external heating,internal heating and heat insulation.
We major use external heating and rarely use internal heating and heat insulation.
Another type is the convey ways of melt plastic.

As we all know,most of small and medium size plastic products always need hot runner plus
cold runner from mould design and economy. The convey ways of melt plastic has two types,
main runner nozzle injection molding without manifold and nozzle and injection molding with
manifold and nozzle.Main runner single nozzle is belong to easiest hot runner gating system
without manifold. Single main runner nozzle replace the function of primary main runner cup and bush.
Main runner nozzle can be direct gate,pin point gate or other type gate. In the single cavity mould,we also use hot nozzle.

Hot runner system classification is easy,but hot runner system is complicated.
Hot runner system is both the extension of injection machine nozzle and mould runner system.
Compare to cold runner,it expand process injection quantity and reduce the pressure loss.

According to melt plastic run through main runner nozzle into nozzle under manifold ,
hot runner system classification still has many series.
Anole hot runner is specialize in hot runner system.
