Hot runner function

Date:2012-02-21

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.
 
Although the composition of hot runner is simple,but its every part plays a very important role.Usually,good quality,structural design and material requirements of hot runner are very high,that is the premise to ensure the quality of hot runner and hot runner function.
