Mold Hot Runner into the plastic choice of three "needle valve mouth"

Release date:2019-04-17 Author: Click:

With the hot runner technology increasingly applied, hot runner mold in the proportion of plastic mold will gradually increase。 Application of hot runner technology in the rapid development of foreign countries, many plastic mold factory production molds used in more than 50% of the hot runner technology, and even more than 80%, the effect is obvious。 Hot runner in the country have also been used for production, but overall less than 10%, the gap is huge, which means that the industry has a considerable market space there。 Hot runner technology is widely used plastic mold a major change。 In injection molding, which has a considerable number of unparalleled advantages, to say the same, with further development of its technology and manufacturing costs to reduce the hot runner technology will be more and more show its tremendous advantages。 Development of hot runner components of the national standards, and actively produce inexpensive high-quality components, hot runner technology to promote publicity is the key to the development of hot runner mold。 Needle valve for the valve needle by the mechanical or hydraulic control, the valve needle will be closed at the end of the ditch gate, that is, the product has not yet fully condensed, the glue into the system has been closed, which is to shorten the forming cycle 。 Needle valve nozzle can be made without marks, and only leave a trace on the product surface or not, which is applied to the surface of the best programs。 It provides a sufficiently large gate size to reduce shear heat and pressure losses, thereby reducing filling stress and providing a very pleasing forming environment that is as effective as extremely difficult to form plastics or very sensitive fill materials。 At the same time can also be the feed gate for sequential control。 By extension, all plastics can achieve better product performance, expand the amount of plastic injection and increase the speed of injection。 For "extremely thin" plastics, "drawing" is also avoided。 【Suzhou Mold Casting】
