The application of hot runner in the mold field has gradually matured, and the two main key factors of hot runner technology are the key to measure whether the hot runner technology is good or not. Mingyang technology will give you an analysis:
The first key technology is: plastic temperature control
   in the hot runner technology, the control of melt temperature is very important. Most of the product quality problems in the production process come from poor temperature control, such as quality problems in the injection molding of the gate of the needle valve hot runner system, difficulty in closing, inconsistent filling time of parts in the multi cavity mold, uneven filling quality, etc. If possible, try to choose a hot runner system with multi area temperature control, which can improve the flexibility of use.
  the second key technology is the control of plastic flow
   during the operation of hot runner, the flow of molten material needs to be balanced, and each gate must be opened at the same time to ensure that the molten material fills each cavity synchronously. Therefore, in the case of large weight difference, it is necessary to design the balance of sprue, otherwise there will be insufficient pressure holding of some parts and excessive pressure holding of some parts. Therefore, the size design of the hot runner is required to be reasonable. If it is too small, the pressure loss of the die is too large. If it is too large, the plastic will stay in the hot runner for too long and damage the material performance.
   the above two points also test the technical content and product quality of a hot runner company. Mingyang technology has many years of experience in hot runner technical design and production, and the product quality is excellent. The design software adopts imported CAE software to ensure the best from design to production. Hotline 05684713123, website: http://www.tzrld.cpm
