The hot runner system is divided into adiabatic hot runner and micro semi hot runner systems. The design of adiabatic flow channels is complex, but the effect is good and the maintenance cost is very low. The structure of micro semi hot runner is simplified, stable and easy to use, with low failure rate. Due to its simple structure, maintenance costs are low, providing greater assurance for production stability.
Hot runner classification: open type (for micro semi hot runners), needle valve type (for adiabatic runners). The needle valve type hot runner saves materials, and the surface of the plastic parts is beautiful, while the internal quality is tight and the strength is high. There are two major types of needle valve hot runners in the world (based on injection principles): cylinder type and spring type. The cylinder type dependency controller and timing controller control the closure of the needle valve pushed by the cylinder, which has a complex structure but simple design. Mainly including DME (USA), INCOE (USA), MOLD MASTER (Canada), HUSKY (Canada), AKOMA (China), etc. Japan did not enter the Chinese market in the 21st century. The cylinder type requires high mold accuracy due to its structural characteristics, while debugging and maintenance are relatively complex. MOLD-MASTER can be called a Rolls Royce in the hot runner - the heating part is on the nozzle. The significant cost among them is in debugging and maintenance, and customers are basically unable to maintain it themselves. FISA (Japan), a spring type company, has the biggest feature of relying on the balance of spring and injection pressure to control the needle valve switch. It is easy to assemble, debug, and maintain, and the mold accuracy is not high. Domestic customers in Japan have basic maintenance capabilities and are widely used in household appliances, automotive accessories, and precision multi-cavity molds. The difference between spring type and cylinder type is that they cannot be controlled in a timely manner and cannot effectively solve the problem of welding marks. On the basis of successfully summarizing the experience of thousands of sets of hot runner systems, plastic beauty technicians have successfully developed: small diameter wear-resistant nozzles; Spring needle valve and internal heating nozzle. Plastic Beauty Hot Runner has developed an embedded heater, which is directly embedded in a copper sleeve. Due to the excellent thermal conductivity of copper, the embedded copper heater is placed on the hot nozzle, greatly reducing the maintenance cost of the hot runner hot nozzle
The price is positioned or close to (China's market value), MOLD-MASTER, INCOE, DME, AKOMA, HUSKY, FISA, SM (Plastic America China). The popular stacked molds abroad are none other than hot runner molds. In fact, hot runner molds reduce many design requirements and provide great convenience for designers to develop more mold structures. Su Mei not only inherits the leading technology of Canadian hot runner, but also integrates relevant injection molding on this basis; Electric heating and precision machining technology. The company fully utilizes human resources and introduces the most advanced on-site production and customer service system to create a management system that fully satisfies customers.
