If it is an old mold, it is possible that the hot runner heating pipe is broken, please find an electrician to solve it. Just fly the new mold to see if the nozzle is vertical, if there are any chamfers that have not been avoided, if the hot runner is not properly installed, and if the glue inlet has been deformed by the nozzle. If all of these are ruled out, it is because the internal water inlet is too small and the glue injection pressure is excessive. These are the only ones on the mold. If the beer maker is inexperienced and the nozzle temperature is not adjusted properly.

Two key factors in hot runner technology

The use of hot runner in the field of molds has gradually matured, and the two main key factors of hot runner technology are the key to measuring the quality of hot runner technology. Below is an analysis and analysis for everyone:

The first key technology is: control of plastic temperature

The control of melt temperature in hot runner technology is very important, and most of the product quality problems that occur during the production process are due to poor temperature control, such as needle valve typehot runner systemQuality issues and difficulties in closing during gate injection molding, inconsistent filling times for parts in multi cavity molds, and uneven filling quality. If possible, try to choose a hot runner system with multi zone temperature control to improve the flexibility of use.

The second key technology is the control of plastic flow

The flow of molten material in the hot runner operation needs to be balanced, and each gate must be opened simultaneously to ensure that the molten material synchronously fills each cavity. Therefore, in cases where there is a significant difference in weight, it is necessary to design the balance of the runner, otherwise there may be insufficient pressure retention for some parts in the stamping die and excessive pressure retention for some parts in the stamping die. So it is required that the size design of the hot runner should be reasonable. If it is too small, the pressure loss of the stamping die is too large, and if it is too large, the plastic will be damagedHot runnerExcessive dwell time can damage material properties.

?? The above two points also test the technical content and product quality of a hot runner company. Our company has years of experience in hot runner technology design and production, and the product quality is excellent. The design software adopts imported CAE software, ensuring that we can achieve the best from design to production.
