热流道的优点及常见问题热流道技术的优点1.节省塑料原料由于热流道无冷凝料。
或很小的冷料柄，基本上无冷流道浇口料不用回收，尤其是价格昂贵，不能用回料加工的塑料产品，可大大的节约成本。
应用热流道如果正常生产一般2-3个月，就可收回热流道成本。
2.提高产品质量与双分型面的三板模相比，热流道系统内的塑料溶体温度不易下降，保持恒湿，不需要像冷流道模具，以提高注射温度来补偿塑料溶体温度的下降，所以热流道内的塑料溶体更易流动，对于大型，薄壁，难以加工的塑料产品更易成型，脱模后产品残余应力低，产品变形小，热流道系统使浇口更小，选用针阀式热流道进浇点就只能看阀针痕。
3.提高生产率，实现自动化生产塑料产品经过热流道模具成型后，无需修建浇口，取冷凝料柄工序，有利于浇口与产品的自动分离，便于实现生产过程自动化，缩短塑料产品成形周期。
4.强化注射机功能热流道系统中塑料溶体有利于压力传递，流道中的压力损失较小，可大幅度降低注塑压力和锁模力，减小了注射和保压时间，在较小的注射机上更容易成型长流程的大尺寸塑性，可选择较小的注射机和减少注射机的费用，强化了注射机的功能，改善了注塑工艺。
5.提高产品一致性和平衡性6.热流道系统可按流变学原理人工平衡，通过温度控制和可控喷嘴实现充模平衡，自然平衡的效果也很好，对浇口的精确控制，保证多腔成型的一致性，提高了塑件的精度。
2温度控制器常见故障1 温度控制器显示不正常，显示“、HHH”，航空插头没有插好或热电偶线接触不良，或热电偶合断路。
显示“LLL”热电偶线反接。
2 温度控制器跳闸，一般是加热元件漏电或内部短路。
3 温度控制器温度显示已达上限，但温度还一直上升，加热器继续工作，故障一般由可控硅或固态继电器损坏引起。
1. Less plastic raw materialsAs the runner without condensing material. Or a small cold material handles, basically no gate cold runner material without recovery, in particular, is expensive, can not return material processing of plastic products, can be a big cost savings. If the normal production of hot runner applications usually 2-3 months, you can recover the cost of hot runner.2. Improve the product qualityParting with the two-mode three-panel, compared hot runner system plastic melt temperature drop is not easy to keep constant humidity, do not like the cold runner mold, to improve the injection of plastic melt temperature to compensate for the temperature dropped, so the hot runner plastic melt flow more easily, for large, thin, hard to process plastic products easier to shape, mold release, low residual stress after the product, product deformation is small, smaller gate hot runner system to choose the needle into the pour point of the hot runner valve needle marks can only look.3. Increased productivity, automated productionThrough the hot runner molding plastic products, the need to build the gate, take condensing material handles processes conducive to the automatic gate and product separation is easy to realize automation of production processes, shorten the plastic molding cycle.4. Strengthen the function Injection MachineHot runner system plastic melt pressure is conducive to transfer, flow pressure loss in the small can greatly reduce the injection pressure and clamping force, reducing the injection and holding pressure time, smaller injection molding machines on the long process easier The large size of the plastic, choose the smaller injection machine and reduce the cost of injection machines, injection machine features enhanced and improved injection molding process.5. Improve product consistency and balance6. Rheological principle of hot runner system can be manually balanced, controlled by temperature control and the filling nozzle to achieve a balance, the effect of the balance of nature is also very good, precise control of the gate, to ensure the consistency of multi-cavity molding, to improve the precision plastic parts.2 Temperature Controller Fault1 shows abnormal temperature controller, display ", HHH", Aviation plug not plugged in or thermocouple, poor contact, or the thermocouple circuit together. Display "LLL" reverse thermocouple wire.2 temperature controller trip, usually leakage or internal heating element circuit.3 temperature controllers have reached the maximum temperature display, but the temperature has been rising and the heater to work, failure generally silicon or damage caused by solid-state relays.。
