Throgh this article let's talk about the hot runner material leakage,good hot runner design make the good hot runner protection for hot runner mould.

Commonly,It's hard to find out the hot runner material leakage phenomenon,because just form the mould performance can find it.But If careful observation,we can also find some leakage phenomenon.Generally speaking,when settle a new hor runner system,the operator are very clear for how much shot capacity time for the melt runner.For example,If the melt runner can contain 3 times shoy capacity(Each shot capacity is the volume of melt runner/mould cavity).So when inject
three times,there would be melt plastic left in the mould cavity.If without the melt plastic,maybe the melt plastic has leak into the manifold slot.When using the hot runner,we must ensure the that injection quantity in the machine is set correctly.

when In the operating process, another sign of material leakage is part of the cavity or filling material products not completely. This is because the injection of molten material part leak to the manifold solt,caused the product of injection not sufficiently.In the control of the injection molding machine interface, this show for a sudden change in the process parameters.

If the operator doubt the exist of the leakage,should turn off the injection machine right now,After cooling the machine,then we can start the examination.
After cleanning the system and detect the leak reasons,we should asl check with all the parts.This is because the temperature of the overheating or cleaning process is likely to cause damage to the parts. If found parts was damaged, should instant replacement parts.

What deserve to be mentioned that high quality mould of hot runner brings the operation advantages than operation process of the possibility of hot runner material leakage problems with material.so when the customer buying the hot runne,should deal with all kinds of hot runner of the design and performance fully understand, to make sure the important parameters of the machining accuracy, and for the relevant personnel to provide the necessary technical training.

temperature controller box china|hot runner temperature control system

Compare with cold runner,hot runner should heat by heating system first and keep the temperature .Temperature controller box china --Anole hot runner can maintain the temperature precisely.We realized that if the temperature is too low,the plastics will not melt or not melt completely.If the temperature is too high that decompose plastics and carbonize plastic.It will get a big problem in plastic part or the plastic part will be scrapped.Therefore,you should control the temperature of hot runner.Particularly,with the diversification of raw material and the strong sensibility of temperature of raw material ,we should think more about the temperature control system (temperature controller box china).If you do these, we can guarantee the injection moulding or the quality of the plastic part.

In addition to hot runner adjustment,i want to give you some tips about injection.Firstly,you should heat the mould beforeinjecting .Then you 'd better inject in the air for about 4 times. According to this injection situation ,you can check whethwe the shot weight and speed of injection are in proper operating condition.Lastly,injector inject about 4 times for clamping mold,next you should reduce the temperature and continue to inject.The total times of injection is about 15 .After doing these steps you will find problems or perfect in your products.If you have any other questions about hot runner adjustment or injection please contact me.

It is important to make a choose of hot runner and nozzle,hot runner nozzle types can be dividded into three types,such as pin point gate nozzle,direct gate nozzle,valve gate nozzle. Choose standard has been taken shape with so many years develop.Anole hot runner,professional manufacturer in China.
It is the best choice that complete use cross overlapping and has the system integration thermal conductor in hot runner system. Only then a ring-like overlapping central heating system will have the high pressure loss, to give in the possible situation to avoid. The hot runner should design perfect as far as possible for the daicel, the being flame-resistant rank these high fever sensitive material .The spray nozzle should use the complete cross overlapping open style external heating system. The melt should not divide into several melts in the runner region. The feeding connection's distributed form should adapt the inserting condition, thus may obtain the average temperature distribution. If must use the wear-resisting material to make the head of nozzle, may use the head of nozzle which may exchange, this is a merit. Moreover, may also use a small torpedo head of nozzle. When processes the  daicel ,generally should not use enclosed spray nozzle. If other plastic stipulation use needle valve spray nozzle, the spray nozzle needle's union should reduce the pressure loss as far as possible. If has followed the above suggestion, it will helps to make a high efficiency in the injection process.

make you a fully introduction.

In the injection molding processing, hot runner played more and more important role in injection, hot runner system application has been widely and widely. Correct application helps to save the plastic material also help to improve the productivity.

In the injection molding processing, hot runner and mold used coordinated, and playing very important role. For example, in the be ultra-thin injection molding production (for example handset battery cover), through uses the hot runner easy to produce high accuracy high grade product; Regarding the bad fluid injection molding material (for example LCP), through uses the hot runner to be able to improve raw material fluidity obviously, guaranteed that the injection molding production carries on smoothly; Regarding some large-scale injection moldings, after like automobile's bumper and shutter, television, the shell, the air conditioner outer covering and so on, through use the hot runner, make the difficult injection molding becomes the relative simplification. In the multi-die space's mold injection molding, lacks the hot runner unable to take shape radically. It can be said that the hot runner is the best technology guarantees the runner balanced. Because the plastic has the shearing force in the hot runner, regardless of the mold has the reasonable geometry balance, takes shape the product weight which comes out to be difficult consistently, specially speaking of the multi-die space's mold, if does not use the hot runner, will take shape the product flank which will come out the inside to be lighter. 　　

With the fasten development of mold,hot runner been used widely and widely.It is better to use hot runner in some sistuation,we make a brief descibtion.  

situations need to choose hot runner as below:
1.In product heat sensitive situation
2.product big or in wall thin situation
3.in runnerl excessively long situation
4.in production output big situation
5.to product outward appearance or accuracy requirement high situation
Hot runner system's merit,hot runner advantage is far bigger than the disadvantage .
1st,product thin thickness, guaranteed that the melt can arrive fully, reduces the product distortion degree greatly, improves the product surface quality and the product uniformity greatly;
2nd,the hot runner internal pressure loss is small, the good melt fluidity,density easy even, avoids the injection molding distortion, as well as the size unstable and flaws and so on chromatic aberration;
3rd,completely or eliminates the majority of material(drainage opening material), does not need the artificial cutting drainage opening, does not need to crush again, enhances the material use factor, saves the energy, raised the production efficiency (common shrinkage, packing insufficiency, fusion mark, irregular color, edge, the warp phenomenon also to be possible to improve obviously or to eliminate);
4th,eliminated the additional heat which waste material brings, mold's coolling-off period is only the plastic cooling time, reduced the processing cycle;
5th,hot runner is automatic turnoff runner, improve runner outward appearance, enhanced the automated work degree;
6th,control melt plastic temperature accuracy, eliminated the material degeneration,  guarantee pressure time to be more reasonable, reduces the product internal stress.
7th,reduces the injection molding pressure, advantageous in protects the mold, extension service life.

 The runner used in mold,can be simply divided into cold runner and hot runner.The obvious advantages of hot runner helps easily distinguish from cold runner in the mold injection.Because of amounts disadvantages cold runner has been eliminated day by day in the plastic injection process.

The hot runner through heating  guaranteed  the runner and the plastic maintains molten state. The hot runner system composed by nozzle, manifold, temperature controller box and so on several parts. The nozzle includes two kinds generally: Open style hot runner nozzle and pin valve type hot runner nozzle. Because the hot runner nozzle form directly decided the hot flow channel system selects with mold's manufacture, thus often corresponding divides the hot flow channel system into the open style hot runner sysunner system.
Cold runner system create the wast each time die sinking cane, when injection molding spare part, the multi-die space cold runner system will create the massive raw material waste, this will enable the pattern making profit space suffer injury seriously. The cold runner merit is easy to use,  also can meet certain artistic needs well. The cold runner can reduce injects uses for diaphanous transparent parts and so on acrylic ester perhaps polycarbonate, avoids injecting in certain parts creates the obvious belt-shaped effect. But regarding the cold runner's shortcoming, besides raw material waste, the cold runner's flaw including caused the entire automation process increased the step. The cold runner mold's partial remove, needs the robot or the worker separates these part from runner. According to runner's size, the waste material value possibility amount to hundred and thousand of US dollars, specially regarding polycarbonate and so on expensive material.
 Regarding the more die space's systems, the cold runner is impossibly entirely as desired. In the multi-die space's situation, the runner plastic would surpass the injection molding part total quantity. At this time, the runner cooling time will surpass the injection molding part cooling time, will cause the mold user's cycle time control by the runner cooling time, this kind of processing situation will be very difficult satisfying. But hot runner can solve this problem, it can effectively increase the total quantity of single die space , because the runner in molten state in the entire processing process.tem and the pin valve type hot runner system.

Why hot runner with low penetration rate in china?

In this respect,hot runner supplier and the mould enterprise need to do more work,in another respect,they need to teach customers how to use the hot runner in correct way.Most customer(including mould enterprise and the injection enterprise)after purchase the hot runner,because of the improper use,usually make the heating elements burn out,even the temperature controller box.In light degree,it will tend to decrease the product quality,in heavy degree,it will cause the mould demaged,the injection machine stalled,and so on.

            
 

Under these circumstance,customers would be mistaken for hot runner is a bad thing.Therefore,develop hot runer technology in china, is a heavy responsibilities to the client of the propaganda and make the injection enterprise accept and really learn to use the hot runner technology is the future main work for the hot runner supplier.

Wide application for hot runner technology is the reformation of plastic mould.in injection moulding,it has quite a number of in comparable advantages,it can be said that,with further development of technology for mature and the manafacuring cost cut,hot runner technology will more and more show its huge advantages.Make hot runner components of the national standards, the high quality of positive producing cheap components, completes the hot runner technology promotion, is the key to develop the mould of hot runner.
