Compare with cold runner system, hot runner suystem has many advantages. But every coil has two side we should know that the disadvantages of the hot runner mold. To study from that, we will make the hot runner system better.

The first is that the cost of the hot runner mold is higher then the cold one. Hot runner component is more expensive then cold runner , hot runner mold cost may be greatly increased. So it is not economic to used hot runner mold to product small amonunt products. But for produting a large quantity of good , hot runner mold can be a nice choice. The second point is that Hot runner mold need high technic machine and professional workers to make. Hot runner mold needs to guaranteed by precision processing machinery. hot runner mold has extremely stringent requirements, otherwise mold will be a lot of serious problems in the production process. Anole applicate imported precision machines and professional workers to ensure the quality of the mold. The third point is the complex repairment. Compared with the cold runner mold, hot runner mold repair ment is more complex . Since the use of improper operation is very easy to damage the hot runner components and may cause great economic losses . Anole has worked in this line for more than 15years, we can make it nicely. Even the hot runner mold got troubles we can repir it nicely. And these are some disadvantages of hot runner system.

Anole is a professional hot runner system maker in china, we have many experience in this line. We have solved all the problems that appear in the hot runner system. And among these troubles the most familiar one that we have faced is the leaking of the system. Here i want to show the solution of hot runner leaking.

The leaking in the hot runner systemm can be divuided into two parts. First is the leaking of the nozzle. In this condition we should first check the sealing a diameter to ensure it is good. The second is that enaure the mold processing size to meet the need of the nozzle. The third point is that, we should know that whether the lack of guide disc diameter of cap damaged due to making. The we should check that whether the hot nozzle is seted in the prople tempersture. The second poing is that the Gate is dripping, flow saliva or outgoing wire. To solve these problems, we should set the temperature of hot runner in a prople one. And then made the gate size in the exact size , not too big. Also we should make sure that if the hot nozzle head is not contact too little (gate too hot), we should to strengthen the mold coolling water. We should check A thickness analysis and the hot nozzle length is in the proble temperature. We should selection the correct, hot nozzle change. Here are some solutions of hot runner leaking.

When in the runner making of hot runner system manifold ,the runner of Hot runner manifold should be reasonable optimization. An optimization design of runner is to ensure that the hot runner system has reasonable plastic pressure, reasonable shear rate and shear stress, reasonable runner to reduce the time when the volume of plastic stay in the hot runner system and speed up the color change, and reasonable friction to heat produced by the plastic melt temperature change, etc. The running making mostly made by drilling (gnu DRILL) of finish machining method, the productivity is higher. But this method of drilling can only make linear runner. In this way the most important thing is to notice when the place is two SPR intersect to light the whole round, also need to polish the sprue tube wall, to avoid runner corner solution for a long time thermal metamorphism, eventually lead to produce inferior products.

Another way to make a runner board is processed with milling method. The runner is composed of upper and lower two pieces of steel block. first, with the milling method respectively in the two and a half piece of steel piece of work out side runner, then put the up and down through the special welding or other mechanical methods appeared. The benefits of this runner is it can be made within any shape is not just straight sprue form, to increased the flexibility of plastic flow control, and there is no flow corner. but users are not easy to clear the runner system directly. Here is the ways of Runner making of hot runner system manifold .

Temperature control box is an important part of the hot runner system. The stability it catches many people’s eyes. Here i want to show you the factor which influence temperature control box stability.

First, temperature measurement, sampling the cycle parameters and data processing temperature measurement circuit to measurement precision. Second, PID control, by regulation reflects the proportion of output current, and the relevant parameters have proportion, integral differential time.
Third, Automatic adjustment. through analysis the capacitance of hair hotline and mould thermal constants, provide its functure of dominant factor ( including the Latent heat and cooling regardless )nomatter How the environment changes , it would contribute to the precise temperature control. Fourth, output mode: according to the environment can be changed . There are two out put modes . First , SSR (PIDD) mode: can achieve accurate temperature control, but the noise of power is much bigger than PWM mode. Another one is PWM (PID) mode: current noise is small, but the specific temperature control ability is worse than SSR mode. Here are the forth factors which influce the Temperature control box stability.

Anole is a professional hot runner system maker in china. Temperature control box is an important part of hot runner system. here i want to show you the Misunderstanding of temperature control box to help you choice it.

First, some people may think that the if the temperature control box do not move ,it indicate it is stable. This is totally wrong understand. Mold opening and closing cause air flow, and the temperature will change. And if the temperature control digital display does not change, it dees not means the temperature does not change, but the change of temperature is hidden, namely the termperature is showed are not real . The stability of temperatiure control means in the practical work, the system into temperature fluctuation is smaller, the better the stability. The second point is that Many people think the temperature soon will be able to rise to the set value, the thermostat is better. In fact this is a very serious misunderstanding. Heating to meet the heat conduction and heat distribution which should have good temperature curve. Not the sooner the better, excessive heat can not only increase the production efficiency, but also will cause the damage of hot runner and related components. Here are the two main misunderstanding of temperature control box.

Anole is a high quality hot runner system maker in china , we have three main styles of this. Those are pin point gate, direct gate and the valve gate . Here are want to show you the valve gate hot runner system application.

Valve gate hot runner can control the time for the nozzle to open to en sure the cavitity being filled smoothly and tyhe melt can be flow banlancedly. In this way the weld lines can be eliminated and the products can be nicely. That is why valve gate hot runner system is widely applicated in injection the products with high surface quality requirements. The sencond point is that the valve gate hot runner applicate the larger diameter gate, can make the melting liquid flow quickly , so as to shorten the molding cycle time and better protect pressure. And also valve gate hot runner system can Effectively reduce the internal stress of products to improve the stability of the parts. Those are reasons why valve gate hot runner system are application in the moulds.

Anole is a durable hot runner system maker in china. Here i would like to show you the benefits of hot runner system.

Exclude saving the material, shorting the cycle time, hot runner system can realize injection plastic in the side way of the mould. When need this ideas, the mould uauslly need three plate, in this way ,the heavy mother template must be sliding on the guide pin when injection, and this will lead to shorten die life .but when applicate hot runner system, the mould structure will be simple, easy forming, high forming speed, reduce the material when forming the head. The second advantage is it can form Object which is difficult to forming such as: high viscosity, low viscosity, high molding temperature....the third point is that it can Achieve high speed injection molding. Since the runner has been in the molten state.So high speed molding forming is not only Improve the efficiency of forming. it Is obbligato to make the forming thickness products , such as containers , glass... Here are three benifits of hot runner system.
