SAN wan mentioned hot innovation technology and how to improve assembly maintenance ability

Since 1994, needle valve type hot runner processing technology application has made more than ten years. In the sequence valve needle injection application more ideal results have been achieved. The conical autonomous center positioning needle valve, the sealing force directly ACTS on the sealing face of the cone, in the vast majority of areas has obtained the very good use effect. However, the automotive industry in the stability and accuracy of the processing technology of requirements make a higher requirement for injection mold.
for this special request, st sinofi injection molding industry co. , LTD. , design a valve needle, it has a rounded closing device, fixed in the center of an independent positioning device, so that the valve needle movement process smoothly and wear resistance. The needlepoint design solved the problem of heat transfer, even in a large temperature range, is no longer a failure. This innovation emerges, in addition to using cars, also used in other industries.
but the production capacity is greatly increased and the designers to bring new challenges, in order to reduce costs, equipment, and also need to shorten the maintenance time, this also is the requirement of hot runner system. SAN wan in external assembly a valve needle can be adjusted accurately, so even if you don't open the oil cylinder, also can ensure that during an operation can accurately adjust the height of the needle valve. The valve pin card pin lock, can prevent the distortion, loading and unloading is very convenient.
