TZM Hot Runner Sprue

TZM hot runner sprue

Introduction

Hot runner sprue usually works at high temperature environment, so it should have good corrosion resistance, high temperature resistance and abrasion resistance and other properties. Besides, it is also required that under long term high temperature operation not fatigue and deformation. TZM alloy has high strength, high temperature and good corrosion resistance performance, so it is often as hot runner sprue raw material used for TZM hot runner sprue production.

TZM hot runner sprue is an important part in injection molding and hot runner system. In the injection molding, hot runner system is a heating combination which makes melted plastic inject into the mold cavity, and it is compose of hot runner manifold, sprue (nozzle), temperature controller, and auxiliary parts and so on.

Classification

TZM hot runner sprue has many products types, including: valve system hot sprue, multi valve gates hot runner sprue, single valve gate hot runner sprue, pin-point gate hot runner sprue, sprue gate tip hot runner sprue and so on.

Titanium zirconium molybdenum hot runner sprue has many type and commonly used types are open system sprue, valve system sprue, pin-point gate sprue and edge gate sprue.

Advantages

Optimum temperature transition, thanks to the large contact surfaces between the heat conducting tip and the heated material tube;

Reduction of the processing temperature, thanks to the excellent thermal conduction of the TZM nozzle tips. No loss of heat, since there is no contact with the mould;

Easy mounting and protection against leaks as well as less time spent on installation and removal;

Time savings and reduced tool costs;

Outstanding insulation at the front of the nozzle due to the two-component shaft, thus very little heat loss between nozzle and cavity;

Excellent gate quality, due to the advantageous heat transfer at the gate position;

Wide range of processing temperatures,since the temperature profile is linear;

Easy-to-install, plug-in power and thermocouple connections make assembly and disassembly easy.
