Compare with traditional injection mold, hot runner mold does not have runner channel, so the hot runner system is also called runnerless molding system.

This is particularly significant advantage for expensive plastic resin molding. In fact, the major international hot runner manufacturers in the world have been rapidly developed while oil and plastic raw materials are expensive, because the hot runner technology is an effective way to save plastic material.<\/p>\n<p>3) Increasing product quality<br \/>\nThe plastic melt temperature in the hot runner manifold are controlled precisely, so the melt flow is uniform, consistent quality parts can be produced. The gate bar left on the part is small or sometime invisible, so a lot of high quality products on the market are produced by <a href=\"https:\/\/www.acomold.com\/hot-runner-vs-cold-runner-exploring-the-pros-and-cons.html\">hot runner molds<\/a> , such as MOTOROLA phones, HP printers, DELL laptop.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is hot runner injection mold?
