If an injection molder is looped into the design phase, chances are greatly improved that cycle time missteps will be avoided. Certain design parameters like wrapping plastic entirely around a steel component or another non-flat configuration, designing a mold that cannot accommodate cooling lines, ...

(3) after feeding: after the injection is completed, the seat back, the nozzle away from the mold, and then pre plastic, pre plastic end, and then note the seat forward. The utility model is suitable for the plastic with narrow molding temperature, because the contact time between the ...
The present invention provides an improved process for molding thermotropic liquid crystalline polymer, and the apparatus for such process. The process comprises the steps of providing a molten stream of the polymer to be molded; injecting the molten stream into the cavity of the mold; continuously...

This time can be estimated from the dry cycle time of the machine. Injection - The raw plastic material, usually in the form of pellets, is fed into the injection molding machine, and advanced towards the mold by the injection unit. During this process, the material is melted by heat ...
The utility model discloses a time delay slide mechanism of an injection molding mold system. The time delay slide mechanism mainly comprises a shovel base, a spring, a control pin bolt, a slide base, a slide insert, a time delay pin and an angle guide rod, wherein the slide insert is...
aWe have running the mold now,but injection molding process has not improved any much for 4 dimensions ,the 4 dimensions is also out of spec, 我们现在有赛跑模子,但注坯模型过程未改进为4个维度, 4个维度也是在spec外面, [translate] aWe have running the mold now,but injection molding process ...
The mold then closes and the process repeats. The whole process can be repeated very fast: the cycle takes approximately 30 to 90 seconds depending on the size of the part. After the part is ejected, it is dispensed on a conveyor belt or in a holding container. Usually, injection ...
mold temperature,injection time,packing time and cooling time,and the influence of packing pressure and melt temperature was more obvious.The optimum parameter combination is: the mold temperature is 75 ℃,the melt temperature is 225 ℃,the injection time is 1.3 s,the packing time is 10 s,the...
