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.

manifold seal and fixture

Manifold is the master parts in hot runner system.Thus,manifold seal and fixture play an important role in the manifold.

Let me talk about samething about the manifold seal and fixture:

If you want to avoid leaking plastic melt from manifold,you should consider the effection of thermal expansion.In cold runner system ,after injecting the plastic melt will solidify quickly so that it is hardly leak.However,in hot runner system,a atate of plastic melt can continual flow .
Under the room temperature,we assemble the manifold seal and fixture of hot runner system to produce the goods.

manifold seal and fixture
 

Manifold seal and fixture--why the manifold leak and the preventive measures

The thermal deformation of manifold expecially the nonuniformity of thermal deformation and the instability of temperature control will cause leakage.The unsuitability of design,fabrication and processing technic of manifold also will cause leakage.The main resons are that the unsuitability of injection process ,the extra-high tension of injection and the exorbitant temperaure impact.The manifold seal and fixture can prevent manifold leak . The places where often have leakage are end face of runner and the joint between manifold and nozzle or manifold and sprue nozzle.
The manifold seal and fixture include metal-o-ring and hollow metal-o-ring.Hollow metal-o-ring mostly used in high temperature and high pressure situation.Metal-o-ring often used in the back of the nozzle which is contact with manifold.

Anole hot runner system is the injection moulding hot runner ,hot runner installation for hot runner mould.This artile will introuduce the Installation for hot runner mould.

1).Check the mould design match to the drawing.sarying the nozzle sealing surface and the nozzle installation benchmark.put in to the mould carefully.After confirm the nozzle oufit in place,take out the nozzle,check the nozzle sealing surface whether in position.Such as bad cooperation or not in the position to find reasons.If it is good,put the nozzle into mould ordinally and confirm with nozzle in place,then use depth indicator measure the nozzle height higher
 than the nozzle mold A plate(the general standard is 10 cm-12 mm)

2) insert center location pins,check turns positioning pin, center pad is, then put in hot runner on the sealing face "O" type ring slot.

3) installed with screws (shunt board,lock shunt board), confined pad is, hot runner shunt board thermocouples.

4) to facilitate the wiring,the power supply will lead wire, hot runner thermocouple heating circle lead wire,with number pipes to mark.

5) after the completion of the assembly,with depth indicator measuring pressure pad is whether with the height of manifold is the same.(the general standard is higher than the bedding block mould plate 10 to 20), confirm the back cover mould plate height and lock screw cover plate.

6) wiring: the power into the slot and line pressing board their fixed, cuts off redundant lines,embedded φ2-3 wiring head. Confirm connectors: HOUTUR standard for the power cord by male connectors,hot runner thermocouple meet female connectors.

7) field wiring is usually have two kinds of situations:one according to the hot runner connection mode of access connectors.Another provide according to the customer the connection mode of access connectors.

8) after the wiring and connectors in the junction box and fixed in the mold.

9) after the completion of the assembly with a multimeter detection (hot runner heater and thermocouple) resistance and insulating value is normal or not.

Hot runner installation,hope this file can help you know more abou the hot runner knowledge.

PET bottle molding solution| preform bottle solution

PET bottle molding solution| preform bottle solution If the cavities is not too many.then PET bottle mold solution is not very difficult at all.PET bottle molding solution preform bottle solution techonology shows as bellow:you need:

1.recycled material is allowed to be used(this is only for using bottle.not for  water bottle or any other  drinking bottles),but you can't use recycled material only .new resin material must be used with it.

2.the size of the preform bottle and the caliber of the size is important.and also whether the prefor bottle caliber has taper is also important.
3.specific injection machine is needed for PET preform bottle molding solution
4. valve gate hot runner system is needed for PET preform bottle molding solution.this is special hot runner system .it doesn't use thermocouple to controller and test the temperatrure of each injection points.but used voltage contorller ,and also the controller box that used for PET preform bottle molding solution is also different than normal temperature controller box.On the other hand.this kind of PET bottle hot runner system is much cheaper than other valve gate hot runner systems.(some countries still use cold runner to inject PET preform bottles and then cut the runner.like some places of India).
5.different thickness and degree must controllered very well. in the later article we will talk about the PET preform bottle injection problems

    Hot runner heater is a crucial part of hot runner system. Hot runner heater has many different ranges, such as hot runner coil heater, spring heater, heating rod, heating pipe, right angle heater etc.

      

hot runner system outline|hot runner injection

Hot runner injection mould is one of the most popular runner less mould. Aggregate exist in pouring system not only waste the raw material and rise the energy consumption of injection machine,but also increase a process of clean runner scraps. If we adopt hot runner injection molding method of no runner scraps, we may cut the producing cost.

Hot runner Injection molding of no runner scraps of themoplasics means that pouring system of mould adopt the method of heat insulation or heating to keep molten plastic.Than,we can get the rid of the aggregate in the pouring ststem. The no runner scraps injection mould of thermosetting plastic is similar to the molding of thermoplastic plastics.They keep the plastic in a flow pattern.

Hot runner injection mould set a heater in order to maintain the plastic in moltenstate. Hot runner system equipments include manifold,nozzle,temperature controller box and so on.Those equipments produced by professional manufacturer because of the difficults of high technique.Hot runner injection mould manufacturer and hot runner system equipments producer working together to finish the design and manufacture of Injection mould,also promise the production of injection molding.

This topic talk about the hot runner system outline.I hope is helpful for you.

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.
