In the plastic injection process,hot runner takes important role,error wii be happened in the processing,such as hot runner nozzle jamming.Usually the hot runner nozzle jamming, majority result of runner plastic melt temperature excessively low. For example: The hot runner nozzle structures, the mold transport water, thermocouple quality, heating coil density portion and so on. Also has or installs the period in the manufacture the mistake. For example:hard foreign matter in the hot runner, plastic raw material to have the metal to truncate and so on.
Below simple introduction some runner jamming reason and nozzle jamming solution.
different nozzle type:Ordinary -runner jamming:
1. the runner gate temperature is too low. Reduces the runner place cooling rate, to crystal plastic hot mouth model whether to choose appropriately, whether mold's heat insulation cavity does suffice enough.
2. the hot sprue's front end temperature is too low. Reduces the area between hot sprue sealing compound  and mold's contacted. Must have the heat insulation gap in hot sprue's front end.
3. the quantity of runner heat is insufficient. Enlarges the diameter of heat insulation cavity, reduces the sprue point's length, checks the spure point in the runner concentricity.
4. the nozzle temperature is too low. Increases heating coil's power. Checks the hot runnerl controls temperature.
5. foreign matter jamming. The heat of dissociation flow channel system, eliminates the foreign matter.
Pin valve type runner jamming:
1. the valve needle is too short or distortion. Check up or replacement.
2. the runner damage, checks the valve needle length  whether too long.
3. the cylinder, air/oil leak. Check up cylinder connection place and in examination cylinder's seal packing collar.
4. the valve needle and the runner place contact is inappropriate, reduces the runner place mold temperature,lengthens the valve needle.
5. the cylinder pressure is unsuitable, to increase/ reduce pressure.
6. pressure maintaining time too long. reduce pressure maintaining time.

Hot runner heating elements usually called hot runner heaters,In Anole we use heating coil and heating strip to control the hot runner temperature.they are also called nozzle heater and manifold heater.

Hot runner heating elements is the main part of hot runner system,the heating precision and the working time plays great influence on injection processing control and the hot runner working stability.Generally speaking,hot runner heaters contains heating coil,heaing strip,tube heater,spiral heater (heating rod) and so on.

 

To keep the plastic stay molten state,we must use hot runner heating elements to heat the hot runner nozzle and the manifold. Demand for heating element, small size, big power (warming faster), when using, easy to change and safe, reliable, and the stability of the heating element and durable service life of hot runner technology is the most important.

Choose hot runner heaters is the key to choose hot runner.Anole hot runner system suggest you use the most durable and most stable heating system to suit for your hot runner mould.

hot runner temperature adjustment

First of all,i want to introduce some useful information about hot runner temperature adjustment ,hope this article can be used for any of Anole's customers in the world.hot runner temperature adjustment is about the technology for the hot runner system of  injection molding and inejction moulds.

• hot runner temperature adjustment - thermocouple

The theory of hot runner temperature adjustment is based on thermocouple's thermoelectric effect. The thermoelectrical potential E produced by thermocouple will change according to the  change of the temperature we  measured.Therefore,we use thermocouple feel the temperature and use the temperature as the information .

• hot runner temperature adjustment -temperature controller

Temperature controller also called  master controller. Meanwhile,every heating zone has a temperature adjuster.Each temperature adjuster has self-governed switch, safe and alerting,besides, it also has a intact set of operating system about temperature control.

The effect of hot runner temperature controller :   measure the temperature of monifold and nozzle also keep the temperature we given.

The reasons of  errors made by temperature adjustment system: 

1 The mistakes of design and manufacture about temperature adjustment system.

2 The mistakes of design and manufacture about hot runner 's pouring system. 

 We talked about all these technical information for hot runner temperature adjustment

Hot runner color change operating procedures

Plastic hot runner injection mould contain hot runner system.Anole is the famous china hot runner brand.Injection molding hot runner
best application for hot runner mould.

After hot runner mould design,choose injection machine is the most important.All the automatic cycle ability of injection machine,should adapt to thr hot runner system.when choosing the injection machine there are some factors need to take consideration:
1.Due to hot runner mould with hot runner,add a manifold,so the thicness of the mould should increase correspondingly.choose the injection machine,we need concern the installation height.
2.For the hot runner mould depreciation.we suggest continuous operation of injection moulding machine,with multistage start to reduce demage.
3. Control the plastic parts movement and reduce the start time.
4.Heating plastic injection mould before let the injection machine start working.
5.Reduce set the hot runner mould time, reduced cooling water pipes, pneumatic, circuit and hot runner temperature control box, etc of the link of time.

Plastic hot runner injection mould in china,anole hot runner system is popular to oversea customer,welcome to negotiation.

Hot runner plastic material

 
 

               

manifold filter net|filter met for manifold
There is a transfered area between the screw rop head and the injection mould sprue.manifold filter net is used because when the melt flows through this area,the way how it moves changes.and for adjusting this changing,there should be something that can decide the size of the screw rod and dimensions.filter met for manifold.for high viscosity material,the angle usually smaller than30°，and for low viscosity material.the angle usually bigger than45°。
the fuction of the manifold filter net
it usually put a manifold filter net between the injection mould sprue and the screw rod
 

hot runner valve injection solution

The magnetic needle valve hot runner systems is used in connection with the hot runner nozzles that require spcial requirements such as difficult flowing material like PC、POM、too many ribs on the products that require higher pressure and fast speed.good out surface requirements etc.for controlled closing and opening ofthe gate.

the magetic valve controls the air tank to open or close thus the needle starts shut-off moving.

The feature and advantages of magnetic needle valve hot runner system：

1.Very suitable for applications in medical technology(clea room technolovy)and food industry because it has a lubricant-free drive.

2.Maitenance-free.

3.Robust and long-lasting because it has few moving parts

4.Ideal combination with full electric machines.

5.Control by 24v/12v signals-international standard voltage signal.

6.Cascade control by injection molding machine possible

7.Low energy consumption.

8.Easy installation because no supply holes drilled.

9.Manual,Mechanical stting of the needle position without dismantling the drive unit.

10.Compact dimensions.

we believe that the best features are not just aboves showed for magnetic needle valve injection system.
