Main Trends Of Hot Runner Technology In Its Components

Main trends of hot runner technology in its components

① It is component standardization. At present, users require mold design and manufacturing cycles to be shorter and shorter, and standardizing hot runner components will not only help reduce design repetitions and mold costs, but also facilitate replacement and repair of vulnerable parts. Husky, Presto, and MoldMaters companies have standard nozzles, stems, and manifolds for quick tool changes and delivery. Now molds can be delivered in just four weeks abroad.

② Reliable design. At present, major mold companies at home and abroad attach great importance to the design of hot runner plates and the research and development of pressure distribution, temperature distribution, and sealing of the hot nozzle connection part. The development and utilization of laminated hot runner injection molds are also hot

③ Miniaturization of components. The components are miniaturized, and one-mold multi-cavity for small products and multi-gate filling for large products can be realized. By reducing the nozzle space, more cavities can be configured on the mold to increase product output and injection machine utilization, which is very important for the modern plastic processing industry where time is money. The nozzle developed by the internationally renowned mold company MoldMaters for small parts includes an integral heater, a needle tip and a melt channel. The volume diameter is less than 9 mm, the gate distance is only 10 mm, and the product can be molded with a mass of 1-30 grams.

point. Stacked molds can effectively increase the number of cavities, and the requirements for the clamping force of the injection machine need only increase by 10% to 15%. Stacked hot runner molds have been industrialized in some developed countries abroad.
