What is a combined heat flow system and what are its advantages?
In the combination of hot runner system, nozzle, shunt plate to form a simple single melt flow into the nozzle directly from shunt plate, so that it can't be skewed flow and death through the threaded nozzle are embedded into the shunt board, eliminates the eliminate such leak between the nozzle and plate on particularly effective.Leakage phenomenon.The conventional liner system is designed to generate thermal expansion, and the combined system is particularly effective in eliminating such leakage.
Picture: combined heat flow channel system
The combined heat flow channel system is located in the center of the mould and has little connection with the mould. Its manufacturing materials do not require high thermal conductivity, nor do they require pretension on the die.This minimal connection provides a high precision and stable temperature curve, so the energy consumption is much lower than that of a conventional heat flow path system.The combined heat channel system can directly preinstall the hydraulic circuit independent of the mould.The valve port directly driven by the hydraulic equipment can also be directly installed on the system, so as to omit the control valve on the traditional machine and make the injection molding more flexible.In addition, electrical and hydraulic lines can also be configured according to customer requirements.Because the system will experience before delivery of electrical, temperature, hydraulic or pneumatic testing, so the customer will be pre-installed system, which can be easily carried out within the mold installation and put into production immediately.
When the mold or systems require regular maintenance, combination can also try to hot runner system USES simple steps removed from the mold, thus can be independent of the mold repair and detection.
In general, the combined heat flow system reduces the maintenance cost.The complete heat flow channel system is based on a modular preset design and installation, in which the wires of the heater or thermocouple are removed during assembly.The wires that connect the heater to the distribution box are placed in a specially designed conduit, which is beneficial for disassembly of the mold or heat flow channel system.At the same time, the integrated heat flow channel system can perform routine maintenance without disassembly, thus saving time and reducing installation
The probability of a mismatch error.
The advantages of the heat channel system are as follows.
No water inlet material, no need for after processing, so that the entire molding process completely automated, save working time, improve working efficiency.
Potassium pressure loss is low.The temperature of the hot runner is the same as that of the injector nozzle, which prevents the material from condensing on the surface of the runner and reduces the injection pressure loss.
The reuse of water inlet materials will degrade the plastic performance, and the use of heat runner system without water inlet materials can reduce the loss of raw materials and reduce the product cost.In the cavity temperature and pressure are even, the plastic parts stress is small, the density is even, in the small injection pressure, the shorter molding time, the injection molding system can be better than the general injection products.For transparent parts, thin parts, large parts or high demand parts, it can show more advantages, and can produce larger products with smaller models.
The standardized and serialized design is adopted for thermal nozzles with various nozzle heads available for selection and good interchangeability.The specially designed and processed electric heating ring can achieve uniform heating temperature and long service life.The heat flow channel system is equipped with heat flow channel board, temperature controller, etc
