Maintain Uniform Wall temperature The temperature of the molded parts at the time of ejection mould is a complex function of the molded part design,cooling line design,material properties,and processing conditions.While high heat transfer rates are desired,an overly aggressive colling system design can actually cause quality problems.As the cooling lines approach the plastic injection mold cavity surface,the heat transfer path between the surface and the cooling line becomes more direct.As a result,there can be a great variation in the temperature across the cavity surface unless the cooling lines are also placed very close together. if you need help, pls contact me, I am Tea, my email is injectionmold2006@163.com whatsapp+8615958816137  skype：injectionmold2006@163.com
