A success hot runner system for mould should be guaranteed by many links. And the most important key technology of hot runner applications is as follows:
1. plastic temperature control
In the application of hot runner system mould, plastic temperature control is very important. Many problems appeared during processing and the products quality is rooting in the bad temperature control of hot runner system. Just as using valve gate nozzle to inject the plastic products and turn up the products bad quality of nozzle, the difficulty of the closing valve needle, the quality and inject time of multi-cavities mould is incongruent and so on. If you can, pls choose more temperature controlling to control hot runner system to increase flexible of using and adaptability to change.
2. plastic flow control
The plastic should keep a balance flow in hot runner system. Open the sprue I the same time to fill the cavities. With regard to the differ greatly weight of parts, the mold needs a sprue dimension designing. Otherwise, some parts mold filling pressure maintaining will be not enough, over or has a big pverlap and bad quality and other problems. Hot runner sprue dimension should have a reasonable design, too small will cause losing pressure, too big will damage material property and cause the parts shaped with unsatisfing using demands. There are mould flow soft ware to help customer to set the best hot runner design.
Last week Anole hot runner attends Chinaplas in Shanghai. There are so many exhibitors and visitors come and visit our booth to talk about the key technology of hot runner application and business relationship. If you have any problem of hot runner system, we will try our best to 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.

This article will talk about hot runner function,hot runner advantege in injection mould moulding hot runner,Anole,famous hot runner for mould brand and hot runner supplier in china.

In injection molding process,hot runner used with mould,play an important role.For example,in the production of plastic injection ultra-thin parts (such as the cell phone battery cover),through the use of hot runner can easily produce high precision,high quality products;For the poor liquidity injection molding materials (such as LCP),through the use of hot runner can obviously improve the liquidity of raw materials,ensure injection production running smoothly;For some large injection molded parts,such as car bumper and door plank,TV shell,air conditioning hull,after,through the use of hot runner,make very difficult molding become relatively simple.

In many of cavity mould injection,lack of hot runner simply cannot be forming.That is hot runner is the best technology to ensure the flow balance.In many of the mould cavity injection,lack of hot runner simply cannot be forming.Hot runner is to ensure that the best technology flow balance.Because plastic in port in shear force,no matter how reasonable the geometry of the mould has balance,the products forming out of is difficult to consistent weight,especially concerned for many of the mould cavity is,if do not use hot runner,the products ouside forming out will be lighter than the inside.

To the plastic processing manufacture,as long as there is a certain batch injection production,using hot runner is economical.Because hot runner technology help enterprice deduce the waste material in injection moulding production.In most case,waste material can not used for recycle.Some times the waste material weight is equal to producets.If adop traditional injection type,it mean that the waste material is as manfg as the products.Valuing,use hot runner,can save 30% ~ 50% of raw materials.In addition,would help reduce the wear and tear of mould,extend the service life of mould.Generally speaking,hot runner service life is twice times longer than small gate mould.
