Automatic demouding function is the main features of the Hot runner mold, which could raise the produce efficient a lot and lead to the output of the injection molding machine many more than use the cold runner one, and turn the automatic production into reality of the Injection Molding Machine. Compare with hot runner mold, in the produce course of the cold runner mold, one worker must be needed to serve it. Because there is a cooling tail left in the cold runner mold that can not remove it away, so, in the every cycle time, it must be take out of by the workers hands, if does not do that, the tail will be left in the mold and lead to the mold can not work normal. So, its production effient lower than the hot runner mold more, but its price is a main advantage. Computer-Aid-Design System Our CAD system is an interactive system, by which our designer could make a timely modify after got the customers idea. In this system, we mainly adopts the following software: Auto CAD, Pro-engineer and Cimit. Parts? Standardization In the course of designing and manufacture the parts, we are always trying our best to produce standardization parts and standardization spare parts in order to make maintain more easy and make all of the same parts could be changed each other freely. Machine Equipment In order to raise our products quality, we introduce advanced CNC center from Taiwan, Japan and Germany. It has promoted our product quality a jump. Mold Frame The mold frame machined by CNC center, its place tolerance in every two cavities below 0.01mm. It makes sure the assemble precision of the injection mold. Key parts After a date using time, the injection molds those produce by other factories are comeing up eccentricity problem, but our clients have never complained this kind of problem to us, because we have unique eccentricity-rectified system, which could eliminate this problem before it emerges. Eccentricity-Rectified System Those key parts (cavity core, cavity and half-ring of neck) entirely made of high quality mold steel from Germany or Sweden, its rigidity up to HRC42 45m after heat treatment, which could ensure the finished plastic products precise and prolong injection mold?s using life effectively. Hot Rrunner System Hot runner system is the key technical of prefrom injection mold. Independently controlled hot runner nozzle makes the prefroms molding course on controlling more easily. Cooling System As all know, it is very important to the injection mold that keep the temperature on the expecting value in the long time production course. So, in the mold body, cooling system is not least, the cooling system of us is special designed with very high efficient, connectting with the tap water, it could meet the demands of long time and automatic production and always keep the temperature under normal condition; if combined with water chiller, the result will get better. Tailless Design Our perform adopted tailless design, which could drops the workers labor intensity, because it is no need to cut off the back-tail of the perform by a worker with a scissors, when the preform in the blow molding course.
