Chairs in the office hot feet mold to the successful use of
Office Chairs feet used to PA66 +30-60% GF Plastic poor liquidity, product diameter of 600mm, there are five foot stool, the thinnest rubber 3mm, the thick rubber 5mm, each of the Department of a large number of foot stool tibia, and foot stool for the middle column shaft bit with digital, there are dimensional accuracy and surface with the requirements of the die used in Guangzhou Ying Fai Hot Runner Technology Co., Ltd. (INHUI HOT RUNNER SYSTEM CO., LTD) of SHEN-1 hot runner system, a single Tsui + Tsui outlet ring head, gate diameter of 2.5mm, the middle and then glue into five sub-latent plastic mouth into the plastic stool to five paw, and before the middle of column-mode digital foot stool placed hot mouth, the middle column diameter 50mm, column spaces no cooling water, heating hot runner temperature of the middle column can not be too high to require a certain thermal insulation Tsui effect, the injection mold manufacturing and processing have a certain degree of difficulty, before and after injection when the mold temperature refueling aircraft required to pass 120 degrees of heat oil, to keep mold temperature 90 degrees, injection molding PA66 +30% GF material, the hot temperature of 260-270 degrees Tsui products to reach 1500 grams weight, injection molding PA66 +60% GF material, the hot temperature of 320-330 degrees Tsui, products to reach 2000 grams weight, smooth surface, non-shrinking and dissatisfied with the phenomenon of injection.
Conclusion: In addition to the mold manufacturing and injection molding process with a certain degree of complexity, the hot runner is also very critical of the selection through INHUI hot runner SHEN-1 system in the success of this mode the typical application, it can be seen here on behalf of Hot Runner products today's Chinese-made hot runner with a higher level, with foreign countries can be comparable to well-known brand hot runner.
