Reasons for using hot runner system
Anole is a professional hot runner system which has extensively used in mould maker in china. reasons for using hot runner system can be noticed as follows.
First, Molding cycle is shortened, the channel is the connect of the injection molding machine and the gate of the products making .A cold runner,since the friction and heat loss of fluid moving , will cause the loss of the injection pressure, long cooling time molding, waste form. But all these things do not happened with hot runner system . Because the hot runner can shorten the distance from the nozzle and refined into plastic bits ,to avoid the loss of injection pressure in the flow of the cooling channel, saving cooling time, so that can shorten the molding cycle. Second , hot runner can save material , since all the channel of the system is the hot and, that ensure the material are all in the channel, so that we can save them. Third, hot runner can improve the products quality. plastics in cold runner in the process of filling channel will be damage , since the channel side wall is cold, cold air contact friction, make its head always cold material for a period of very poor quality, the cold material into the mold cavity, injection product will be defected. If you use hot runner these problems can avoid. Last but not the least, using hot runner , we do not need to cut the sprue by ourself. So that can help us improve the working speed and it is benefit for production a large quantity goods .
