In the injection molding cycle,the cooling time consumes more than 70% of the molding process,optimizing the molding cycle time can be done through the selection and the design of appropriate cooling system that will be able to achieve equal distribution of the temperature along the part and ...
Injection molding cycle time directly influences plastic part cost and capacities, so keeping it as low as possible is the overarching goal of engineers and project managers. When getting quotes from various injection molders for plastic parts, they may be confronted with divergent cycle time ...
Stabilized injection molding when using a common mold part with separate complimentary mold parts A process for injection molding plastic products having a closed end and an open end with laminated walls terminating in a rim at the open end. A first common mold part is combined with a first ...
A cycle control for plastic injection molding machines. All time- responsive machine controls are eliminated by initiating or terminating machine functions in response to actual, physical properties experienced by the machine or by the plastic or in the mold, rather than in response to elapsed-time...

In PP the cooling time was reduced 77%. In glass filled PBT, it is 70%. Glass-filled Nylon has a 67% reduction without negative physical properties. Read More » A unique colloidal silica processing aid from Energy Strategy Associates, Inc. slashes molding cycle times. Ultra-fine bright ...
The method of the present invention relates to reducing cycle time in injection molding machines that are running large capacity molds, such as multiple cavity preform molds, and require a high volume supply of quality melt. Specifically, the present invention proposes using a continually plasticizing...
For each injection molding cycle, Figure 8 shows the plasticizing work and the corresponding injection work. For the first cycle 0, the material was plasticized in manual mode, which is why no plasticizing work was recorded by the machine. The increase in plasticizing work with increasing screw ...
where 𝛼α is the crack size, N is the molding number, and C is a constant of the tool steel. According to Formula (1), in the initial crack stage, the (𝑑𝛼/𝑑𝑁dα/dN) value is large, the crack easily grows, and the growth speed is fast. With the progress of fatigue...
