High hardness beryllium copper alloy MoldMAX HH is equivalent to standard mold steel with strength and hardness, but MoldMAX HH thermal conductivity is 4 to 6 times that of steel. MoldMAX HH is widely used in injection molding cores and mold cavities, blowing neck molds and cutting positions. MoldMAX HH hardness is more durable than other high conductivity copper alloys. MoldMAX HH's anti-seize properties are particularly suitable for sliding and mating with other mold materials, even with MoldMAX HH materials.
Therefore, hot runner inserts will be produced using MoldMAX HH to improve the quality of the product, shorten the molding cycle, the most important thing is to save raw materials to reduce costs, but also help to greatly increase the life of the mold. But MoldMAX HH copper alloy prices are expensive, Hot runner mold costs may increase significantly. If the part yield is small, the mold tool costs a high proportion of the cost of the economy. Therefore, the use of MoldMAX HH copper alloy is relatively small. With the wide application of this hot runner system in injection molds, MoldMAX HH copper alloys are gradually being used.
In the injection mold, hot runner system can not be separated, because the hot runner system can improve the quality of the product, shorten the molding cycle, the most important thing is to save raw materials to reduce costs, but also can help greatly improve the service life of the mold. With injection molding With the continuous improvement of technology and people's pursuit of high-precision plastic products, the traditional cold sprue mold can no longer meet the needs and can not meet the precision requirements of modern products. When using cold runners, it will produce mainstream ductile aggregates. When the mold is opened, the distance between the molds is large and it is not easy to demold. If the hot runner system is used, the resin will always melt on the product and will not produce the main channel aggregate, thus shortening the mold gap and facilitating demoulding after molding.
Hot runner system, also known as hot runner system, is mainly composed of hot sprue bushing, hot runner plate, and temperature-controlled electric box. Our common hot runner system has two types: single hot runner and multiple hot runners. Single point hot sprue is to use a single hot sprue bushing to directly inject the molten plastic into the cavity. It is suitable for plastic dies with a single cavity and a single gate. The multi-point hot sprue is used to branch the melt through a hot runner plate. Each sub-heat sprue set into the cavity, it is suitable for single-cavity multi-point feed or multi-cavity mold.
Hot runner features:
(1): no water mouth material, no post-processing, so that the entire molding process is fully automated, saving work time and improve work efficiency.
(2): The pressure loss is small. The temperature of the hot runner is equal to the nozzle temperature of the injection molding machine, which avoids the loss of raw materials.
(3): The repeated use of the outlet material will degrade the plastics performance, while the use of the hot runner system has no outlet material, which can reduce the loss of raw materials and thus reduce the product cost. In the cavity, the temperature and pressure are uniform, the plastic parts have little stress, and the density is uniform. ,In the shorter injection molding time, injection molding products than the average injection molding system better products. For transparent parts, thin parts, large plastic parts or high demand for plastic parts can show its advantages, and Can use smaller models to produce larger products.
(4): The hot nozzle adopts the standardization and series design, equipped with various nozzle heads to choose from, good interchangeability. The unique design and processing of the electric heating coil can achieve uniform heating temperature and long service life. Hot runner system Equipped with hot runner plates, thermostats, etc., exquisite design, variety, easy to use, stable and reliable quality.
(5): During the injection process, the molten material in the pouring system will not be solidified, and it will always be in a molten state without generating casting aggregates. After the first molding, the process of taking out the casting material and cleaning the gate is not necessary.
Hot runner advantages:
(1): to achieve no waste processing, eliminating the need to remove the casting mold structure and removal of the cumbersome process, easy to achieve automatic high-speed injection molding, greatly saving the manpower, raw materials.
(2): In the injection process, the plastic in the gating system is always in a molten state, the flow path is unobstructed, the injection pressure loss is small, and it is conducive to pressure transmission, and can achieve the low pressure of multi-gate multi-cavity molds and large-scale plastic parts. injection.
(3): Because no casting material eliminates the time required for the runner to cool and remove the aggregate, the mold opening distance and the closing of the mold are shortened, thereby shortening the molding cycle and increasing the production efficiency.
(4): Improve the quality of plastic parts to avoid defects such as dents due to insufficient feed.
(5): A wide range of molding temperatures, easy to mold at low temperatures.
(6) Hot runner system can be used for all thermoplastic resins.
What material can improve the quality of the product and shorten the molding cycle?
MoldMAX Beryllium Copper Alloy has been widely used in the injection molding and blow molding industry. This is due to the fact that MoldMAX combines thermal conductivity and strength to shorten production cycles and improve product quality.
