How to find hot runner material leakage
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.

Hot runner mould design procedure
Hot runner mould design procedure
Hot runner mould design procedure,first ensure the feeding port according to the plasic parts and the using requirement.As long as the plastic parts structure allows,set block nozzle and nozzle head in the mould with molding structure would not constitute interference.Hot runner system feeding port can be placed on any position of plastic parts.Plastic injection molding feeding port of the position usually choosed according to experience.For large and complex plastic parts,injection molding feeding port can be applied to the position of computer aided analysis (CAE) simulation molten shaped plastic mold cavity flow situation, analyzes the cooling effect of each part of the mould, ensure the ideal feeding port position.Hot runner mould
Second, ensure the type of the hot runner nozzle head.plastic material and the using charater is the key factor to choose the nozzle head type.Also the
Plastic parts production batch and mould manufacturing cost is the important factor for nozzle head choice.Hot runner mould
Third, according to the production of plastic parts batch and injection equipment tonnage size, ensure each of the mould cavity number. Hot runner mould
Fourth, according to the feed of the position of each mode and the mouth cavity to determine the number of nozzle number. If choose one charging hopper, only need a nozzle, namely choose single head hot runner system; If choose a model more cavity or a cavity exactly two or more charging hopper to forming a product, then must need more nozzles, namely choose more hot runner system, but in some ways except for the cross-flow mould structure.Hot runner mould
Fifth,according to the plastic parts weight and the nozzle number, make sure the nozzle of the size of the radial dimensions. At present the same form of nozzle have multiple size series, respectively satisfy different weight within the scope of the plastic parts forming requirements. Hot runner mould
Sixth, according to the plastic parts structure to determine the mould structure size, again according to the set of mould set and the thickness of the template size selection nozzle length series standard size, finally decided the thickness of the template trim size and other and hot runner system related size.

Why hot runner mould need testing mould?
Why hot runner mould need testing mould?
Most formed products drawback is cased by plasticzing and injection processing,and sometimes relevent to the mold design.The impact factors include:the cavity number, cold/hot runner system design,type of inject portal.location and dimension,and the structure of the product.hot runner mould
In order to aviod bring the drawback from the mold design,we need analysis the mold design and the technological parameter when we need to produce the mould.
After obtain the result of testing mould,(Hot runner mould),the operator usually need to assess the specific situation of mould and avoid to increasing the unnecessarily cost and timedie in the modified process.hot runner mould
In most cases, the evaluation also includes the machine in the process parameters Settings.That is,in order to make up the deficiency of the mould design, the operator may unknowingly was not correct Settings. (hot runner mould)In this case, the production equipment operation process is not normal, because production qualified products the needed parameters Settings range is very small, once the parameters set any small deviation, may result in the end product of quality far beyond the range of error allowed, and the resulting actual production cost often beforehand than the mold optimal costs of much higher.hot runner mould
The purpose of the testing mould is to find out the optimization process parameters and mold design. So, even materials, machine set or environmental factors have changed, still can ensure a stable and continuous mass production of the environment, and not just to get a good sample. That's very important.hot runner mould

Hot runner mould
Hot runner mould
Only after the development of hot runners for thermoplastics did that section of the industry which was still involved with thermoset molding try to develop an equivalent method for thermosets.However,the range of products that would lend themselves economically to "runnerless"molding(as hot runner molding is somtimes called)is very limitied and mainly includes only small products made from phenolics.alkyds,and some rubbers.As a result,the development of hot runner molds is lagging behind,and there is little published in this field.
1.Themperature control from extruder to gate must be very accurate to prevent scorching of the material.
2.Accessibility to the hot runner system to remove hot runners and the end of a production run(or in case of interruptions)must be easy.
3.Thermal insulation is necessary from the relatively cold machine platen and from the heated mold.The mold is heated to a much higher temperature to achieve fast curing in the cavity;this could influence the runner system.
4.Nozzle area is of particular importance because of the unavoidable contact of two elements with differment temperatures.The nozzle forms part of the hot runner system;the gate is part of the mold.
5.Plastic Flow:Because of the higher viscosity of thermosets,the passages must be larger than those used for thermocouplastics.
