There are many factors affecting the cooling of precision injection molds, such as the design of the shape and parting surface of plastic parts, the variety, temperature and flow rate of cooling medium, the geometric parameters and spatial arrangement of cooling pipes, melt temperature, the ejection temperature and mold temperature of plastic parts, the thermal cycle interaction between plastic parts and molds, and so on.

Precision structure industry technology level trend and development trend analysis
In order to continuously improve product reputation and expand the range of target users, downstream electronics manufacturers are increasingly demanding product quality control, and upstream suppliers are required to go through a series of strict review procedures before they can supply them. Manufacturers of precision structural parts usually need to go through a long period of time (usually more than 1 year) of technology and product running-in in order to pass the downstream customer's supply chain system certification and obtain bulk orders. In order to ensure product quality and delivery cycle, save pre-certification costs and research and development investment, and improve the overall profit margin of the product, downstream customers generally choose only a few suppliers with stable supply capacity for a single model of precision structural parts, and it is easy to form a long-term close cooperative relationship after the establishment of the relationship between the two sides.
