open nozzle

open nozzle include pin point gate and direct gate.The open nozzle also can divide into two parts.The one is drop gate ,the other one is adiabatic bin in nozzle.

To the direct gate of open nozzle
This kind of nozzle can keep the high temperature and prevent from freezing.The direct gate with smaller pressure drop should be well deliver the hold pressure .Besides,it can be used in injecting large-scale,long process,thickened wall and deep cavity components.The direct gate of open nozzle is suitable for replacement of heat-sensitive plastic and colouring plastic .Because this style of nozzle is easy to clean that we recommend to process the secondary use of plasic material.

To the pin point gate of open nozzle
The gap of heat insulation is made up of nozzle and the hole in manifold.Pin point gate will decrease the wire drawing and flash.It apply to amorphous plastic and the plastic of slower crystallization such as PP,PE and thermoplastic elastomer.You'd better not select the pin point gate of open nozzle to inject the material of heat insulation and the plastic material which need change the colour.

These information od open nozzle i told stop here.I hope it will help you!

A successful hot runner mold application project needs many links to safeguard. And most important two technical factors: plastic temperature control and plastic flow control.
1. plastic temperature control
 It is great importance of plastic temperature control in hot runner mould applicaion.The product quality question originate directly from hot runner system temperature inaccurate control in many production processes. such as hot needle type injection product bad quality question, when valve type runner needle closure difficult question, polymorphism cavity die has the components packing time and the quality inconsistent question and so on. If possible should choose multi-regions to control the warm hot runner system separately, increases the use flexibility and strain capacity.
2. plastic flow control
The plastic should flow balance in hot runner system. The runner must simultaneously open to fill various die spaces synchronization. Must balance design running size of family mould which components weight phase difference.Otherwise will present some components sufficient mold guarantee presses insufficiently, some components actually sufficient mold guarantee presses excessively,edge oversized bad quality and so on questions. The hot runner size design must be reasonable. The size too small the sufficient mold pressing power lose oversized. The size too large,hot runner volume oversized. plastic resident time excessively long in hot runner system,material performance will damage causes the components formation cannot satisfy the operation requirements.

Hot runner system must work under the sistuation of heat balance,the lose temperature in the injection process must through heat to  compensate.We can see that it is important to control the temperature in the hot runner system.especially the hot runnerl nozzle and the nozzle spray is extremely sensitive to the temperature change,several degree temperature changes possibly cause the plastic products unqualified. Accurate temperature control takes an important role in hot runner operation system.The temperature control meter used the PIDD structure,it can control the temperature change  within 1℃.
The install position of the hot runner thermocouple is the key of temperature control.One is the runner, this place temperature conditions is important to pressure continues and melt fluidity; Other one is the heating output biggest spot, here plastic existence thermal decomposition danger. Therefore, the thermocouple must install in the anticipated temperature roof, can not be put in the heat loss place, such as adds nearby the pressure ring, the seal ring, or hot runner flank region. At present can carry on the thermal equilibrium through the computer simulation analysis, may basically determine the high spot on the spray nozzle and the divergence board .
The hot runner spray nozzle's heating generally uses the external heating method, with screw tubular heater set in spray nozzle's outside. Also has selects the internal heating way, with heats up the stick to insert in spray nozzle's. The hot runner board's heating generally uses the tubular heating stick, loads to the two surfaces of hot runner mannifold after board shape curving.

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.

With the widely use of hot runner system,hot runner technology has been more mature and optimizes day by day.It has reached the achievement of high technology  application,advanced injection molding technology,also high hot runner technology production.
Compares the hot runner mold with the ordinary runner mold , it has the advantage of high injection molding efficiency,good quality of formation models, and saves merits raw material and so on. Along with the polymer industry's development, the hot runner technology is developing consummates unceasingly, its application scope is also getting more and more widespread. The hot frunner is through the heating means guaranteed that the runner and the runner plastic maintains the molten state. Because it is equipped with stick and the heating coil nearby the runner or the center ,it keeps high temperature from the sprue of injection machine to the nozzle,keeps the plastic in molten state.after the engine off,needn't to open the runner to take out the congeals material, only need to heat up the runner to its necessary temperature  when starting again.The hot runner injection molding methods was appeared in the 1950s, after having experienced a period of long time promotion, its market share rises year by year , in the mid-80s, US's hot runner mold accounted for the injection mold total 15%~17%, Europe was 12%~15%, Japan was 10% approximately . But to the 90s, in the plastic injection mold which the US has produced the hot runner mold  accounted for above 40%, accounts for above 90% in massive article's injection mold. The hot runnerl system's superiorities are saves raw material, to reduce the product cost is the hot frunner mold most remarkable characteristic. In the ordinary gating system must produce the massive material handle, when produces the small product, the gating system congeals the material weight possibly to surpass the product weight. Because the plastic has been at the molten state in the hot runner mold, the product cannot prune the runner, basically is the non-waste material processing, therefore may save the massive raw materials. Because it does not need working procedures and so on. waste material recycling, choice, smashing, dyeing, therefore the labor saving, time-saving, the energy conservation falls consumes. , because the runner material which no longer mixes in passes through processes repeatedly, therefore the product quality obviously enhances.
because the gating system plastic maintains fusing simultaneously,  the pressure loss is small when flowing, thus easy to realize the multi-runners, polymorphism cavity die to have and the massive article low pressure injection. The hot runner favors the pressure transmission, to a certain extent can overcome models as a result to make up hollowly, flaws , shrink hole , distortion and the material insufficient forms.  resin applicable scope is broad , the formation hypothesis condition is convenient. Because the hot runner system technology warm consummation and development, now the hot runner not only use in fusing the temperature wide polyethylene, the polypropylene, can also use in the processing  heat-sensitivity plastic which temperature scope narrow, like polyvinyl-chloride, metaformaldehyde (POM) and so on. To easy to produce salivates gathers amide (PA), through selects  hot runner nozzle valve type also to be able to realize the hot  runner formation. Moreover, the operation simplifies, the reduction formation cycle is also a important characteristic of hot runner mold's . Compared with the ordinary runner, reduces molds opened the matched schedule, not only reduced workpiece's drawing of patterns and the formation cycle , moreover advantageous in realizing the automated production. Statistics indicated that compares with the ordinary runnerl, after changing to the hot runner formation cycle to be possible to reduce 30% generally.

With the fasten development of mould technology,hot runner technology also along with consummation.

Hot runner system

                                               -----------------Anole hot runner
 
 

The working priciple of hot runner system:Install the heaters in the plastic mould,Controll the heating and the temperature to keep the mould sprue in a molten state.This looks like the injection molding machine extends its fort to the product cavity's plastic point,make the products more direct relaxed to shape.

Generally speaking,hot runner system contains:
Internal heating system(COOL ONE)
External heating system:1.single point nozzle hot runner system (HOT SPRUE BUSHINGS)
2.multipoint nozzles hot runner system (HOT ONE/GATE-MATE)
3.valve gate nozzle hot runner system (POLYVALUE)

Why there comes hot runner system technology?
What advantages would hot runner system technology bring to us?Most people who acquainted with injection craft knows conventional injection moulding would appear disadvantages usually as follows:
1.Difficulty in filling mould
2.Thin wall deformation of the big parts
3.Waste of raw materials
4.different quality of the cavities mould injection molded parts
 

With the development of the hot runner,these problems are provide a relatively complete solutions.In general,Adopt the hot runner will bring the following advantages:
1.Save the raw material,reduce the cost.
2.Decrease the molding cycle,develop the working efficiency
3.Improve the products surface quality and the machanical property                             
4.Use the pin point gate without the three board type mould
5.Make it economical through side gate molding single product
6.Increased automation.
7.Available valve gate control gate frozen
8.consistently cavities mould injection molded parts quality
9.Improve the beauty degrees of injection products surface

 

However every technology usually exist its shortcoming,let alone the hot runner system.
1.The complex structure of mould,high cost,so the high maintenance cost
2.Begin to work need some time to process to be stable, cause more waste.
3. Appear the melt leak,heating element fault, make big effects on the product quality and production progress

For these three shortcomings,we should pay more attention,through purchase superior quality heating element,manifold and nozzle.using carefully,can reduce the appearance of these unfavorable condition.
