According to foreign media reports, China Molding Press, a hot runner specialist based in Italy, has introduced an innovative, high-quality, cost-effective gate technology that produces high-quality parts without flash and is better Control nozzle temperature, reduce processing and time-consuming, and easier to replace when worn.
Molding companies hope that the molding process window can be opened at any time in order to provide better molding conditions.HRSflow, Italy-based hot runner specialist, with its new HPgate, introduced an innovative, high quality, cost-effective watering The port technology, which can be used to make high-quality parts without flash, differs from conventional products in that the hot-runner system processes the gate on a hard-metal insert manufactured by HRSflow that simply needs to be screwed into the mold during operation , So it is easy to replace when worn.
The new HPgate concept from HRSflow (pictured above) introduces a new technique for screwing hard metal inserts into molds and machining conical cylindrical gates in. If worn, the closure is easily repaired and not There is a need for traditional cost-intensive work on molds.
HPgate frees moldmakers from the time-consuming and complicated process of machining standard cylindrical gates.In fact, due to the gate geometry on the inserts, HPgate eliminates the difficulties associated with cylindrical configurations, including narrow tolerances, As well as the large and variable depth and concentricity between the nozzle and the gate.The hardness of the insert is equally advantageous to the mold maker, which means that the mold plate can be made of softer steel.
Another advantage comes from the special geometry of the nozzle: the conical contact surface gives better control of the nozzle temperature, while the precisely aligned cylindrical nozzle closes to form a seal.When using a conventional conical structure, when the valve is closed, The mouth will form a plastic layer, the mold is opened, the layer from the parts, and may lead to the formation of flash.In order to achieve adequate separation and to avoid flash, usually need to fine-tune the process conditions by eliminating this layer , HPgate reduces the time required to optimize the individual process parameters, and the targeted, faster quality of the build-up is essentially equivalent to an enlarged process window.
By combining HPgate technology with HRSflow's FLEXflow technology, better gate quality is achieved where the position of the nozzle can be precisely controlled to further reduce the impact of process conditions. The gate is beautiful, of high quality Repeatable parts.
