thermocouple probe|thermocouple probe types|thermocouple types for hot runner

what is thermocouple probe?
hot runner thermocouple probe types A thermocouple is a sensor that used for meansuring the temperature of a product.it is a device consisting of two different conductors that producea voltage to a temperature difference between both ends of the pair of conductors. Thermocouples are widely used in science and industry; applications nclude temperature measurement for kilns, gas turbine exhaust, diesel engines, and other industrial processes.
how many different thermocouple probe types?
There are many different thermocouple probe types but mostly common used are J、K and E types,and like other thermocouples such as R S C and GB,there are used for really high temperature calibrations,Each thermocouple probe type can control different temperature range and environment,and for hot runner system.the most commonly used thermocouple probe types are J and K types,that is,a very thin thermocouple may no treach the full temperature range.
How do i choose a right thermocouple types for hot runner?
It can be many reasons,like countries、companies.and it has to be matched with the hot runner temperature controller box wire connection.
defferent thermocouple probe types should have different wire connections ,and because a thermocouple probe measures in wide temperature ranges and can be relatively rugged.when we are choosing the right thermocouple types for hot runner,we need to take the following aspects into consideration:
temperature range chemical resistance of the thermocouple or its material. vibration and abrasion resistance. installation requirements  here we put the perameters of J and K type thermocouple types for hot runner

multiple cavities cap hot runner|multiple cavities hot runner mould

multiple cavities cap mould hot runner
Hot runner system is widely used in multiple cavities hot runer especially in multiple cavities hot runner cap mould .because for bottle makers they want the caps have higher appearance ,also,as well as save the material of the plastic.Thus,a good designing of these hot runner system for multiple cap mould seems more and more important for all the cap makers.
 
16 cavities hot runner cap mould
 
16 cavities cap mould hot runner
Usually,cap mould will choose full hot runner to inject which means the number of nozzles is the same as the cavities number.and of course according to a lot of important aspects such as the mould maker capacity、the injection machine parameter、the requirement of the customers etc.the hot runner system designer will make a decision of how many cavities should choose.besides,the designer will also suggest the best way for all the location of the cavities.
usually the cavities for cap mould hot runner system has 6、8、12、16、24、32、48、64、and some good hot runner system manufacturers will have the ability to produce cap mould hot runner system with 72、96、128cavities.and of course different number cavities cap mould hot runner has different configuration of the injection position.for more cavities cap mould hot runner system the main problem is how to balance the melt flow to each injection points.Basically,a good hot runner system supplier will do M-FLOW for the customer firstly to decide whether the approvaed injection location is the best way to do.
Nozzle for cap mould hot runner system
Mostly,i would say 95% of the cap mould hot runner system use point gate nozzle(see the iamge1) as this kind of nozzle will have very small mark on the prodcuts,but meanwhile the price is very acceptable compare to how much material will waste if choose cold runner and the cycle time.but sometimes,if as the customers' wish and they need really high quality on the surface of the caps,then the valve gate nozzle for cap mould hot runenr system(see the image 2) will be choosen because when using valve gate hot runner .the surface of the cap will be totally smooth but meanwhile of course the price will be much higher than open gate nozzle.

Usually,the manifold will according to the requirement of the mould maker or the plastic prodcts maker .like how many the cavities ,but for hor to locate all the injection nozzles.it is the hot runner supplier's business.
 

hot runner technology|hot runner system technology

Date:2012-01-11

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.

hydraulic locking core pulls cylinder

Date:2012-01-09

hydraulic locking core pulls cylinder

hydraulic locking core pulls cylinder is used in more highly technology injection molding for pulling or sliding the inejction mould core.one of the most advancement of a hydraulic locking core pulls cylinder is it can improves efficiency and speed for a injection mould.Thus,the mold maker can use the hydraulic locking core pulls cylinder to reduce overall cost but increase the quality of the plastic products .

Slide movement example using an angle pin and locking with a heel block

Slide movement example using a standard cylinder to actuate the heel block

Slide movement example of a hydraulic locking core pull cylinder

hydraulic locking core pulls cylinder 

Compare to the traditonal slide assemblies, a hydraulic locking core pulls cylinder has the followeing advantages:
hydraulic locking core pulls cylinder advantage 1-Accommodate Smaller Mold Bases.
As usual if use the traditional method way to pull the slide core when the mould has small mould base,then the mould designer always have to fit all traditional componets in a small mould base.Usually ,the mosre commonly used way is putting horn or angle pins(see Figure 1)to pull the core slide,and there usually a heel bolcks used behind slide core to hold the inejction pressure which not only occupy the mould space but also back off the platen movement.if not using hydraulic locking core pulls cylinder but typical traditional slide way just a waste of mould space and added the cost.
An alternative method is to use a hydraulic locking core pulls cylinder ,it uses a seperated rings that presses into an internal groove inside of the cylinder assembly .it closed when the oil come inside from one port and when it reachs the end,the slide locking part will start working and lock the piston at one postion,and when the inejction is finished,the other oil port start letting the oil in.and it is unlocked .Thus,if using a hydraulic locking core pulls cylinder, the injection pressure from the cavity acts to the seperated ring,locking the slide without needing a heel block.so all these will get a smaller mould base size which resolves mould designs、reduce materail cost and of course overall cost.
hydraulic locking core pulls cylinder advantage 2-lessen material shrinkage.
Another important advantage for using hydraulic locking core pulls cylinder advantage is that the opening movement operates independently and the piston can be retracted before the mould opens,which means it can reduce injection cycle time.hydraulic locking core pulls cylinder .

hot runner vs cold runner

Date:2012-01-07

 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.

hot runner injection mould

For using hot runner system,we gotta make full use of the auto cycling and controll capacity.Thus,there are tree chracters that we need to take into considerations.hot runner injection mould
1.The hot runner injection mould needs more mould claming height.
2.when injecting,we need to consider  when it is under high presure,there will be a lot of compression of material in the runner.
3.we recommond the sequence manufacture process to cotnroller the temperature step bystep.hot runner injection mould
when using hot runner injection mould,sometime the bellowed equipmetns are needed for hot runner injection mould.
1.put a filter net in the main runner ,this is especially used when the plastic manufactuer use recyceld material like when inject crate and big trash bucket.
2.use water system or oil system temperature controller system to control the mould temperature.
3.put a magnet board in the material place of injection machine.
The controlable manipulator can make sure the successfully molding,it helps the insert to install into the mould and then quick taking out to resemble.this is very important equipement for big hot runner injection mould,The hydraulic power of manipulator comes from the injection machine.,and the operation signal comes from the micro control system of the injection machine.And also as well as some other equipments on injection machine can make sure the useful of hot runner injection mould ,increase the efficiency.

Hot runner manifold balance

Date:2011-12-28

Two important balances of manifold:
First, manifold heat balance. The heat balance mainly refers to the manifold heat installation distribute evenly, now majority uses two ways of heating, one kind is inserts the preheater pipe on the hot runner manifold; Another kind is adds on the heating block directly on the manifold. The former heating effect is more obvious. But the thermal equilibrium refers to the evenly of heater pipe and the heating block on manifold detouring and lays aside, the distance between main sprue, the spray nozzle and pressure meson should be considered.

    
 

 
Second, manifold flow balance. Manifold's flow balance is the most important consideration question for designer, this point is important, manifold's even distribution directly influence mold product formation quality and cycle. Regarding the multi-cavity product, this is the attention question, when each runner is an independent product,it request absolute equilibrium

Assortments of nozzle
1.    Heating type:
The nozzle has two heating methods: heating internal and hating external, or mix the two. Short nozzle may use heat conduction, the material is beryllium copper and the temperature comes from manifold. The main runner nozzle’s temperature also comes from injection nozzle.
Assortments of nozzle
2.    Function:
The difference between main runner nozzle and injection nozzle is the former is connected to injection machine and the latter is connected to manifold, the latter has many kinds of output sprues. If the main runner nozzle injects plastic to cavity or cold runner, it is called single-tip nozzle. It also has many kinds of output sprues.
Assortments of nozzle
3.    Sprue type (in the line of hot runner, we always use sprue type to name nozzles)
A.    Open type nozzle: just like the picture a, it is pin point gate nozzle, this nozzle will leave a small trace. Generally, we always classify dia. Below 1.8-2.0mm as pin point gate nozzle. Picture b is direct gate nozzle, this nozzle will leave big inverted triangle trace. We should cut it.
B.    Valve gate nozzle: just like pic. c and d, there is few trace on products.the noral valve gate nozzle biggest dia. Is 2.5-3.0mm.
Assortments of nozzle
4.     Nozzle passage:
The nozzle axes direction is the same as runner direction is called straight line nozzle. On the contrary, it is called abgle nozzle.
Assortments of nozzle
5.    Nozzle NO.:
Besides single-tip nozzle, the others are multi nozzle. There are 2-8 or more nozzles. Decrease nozzle number and smaller manifold dimension can save cost when you choose multi nozzle.
