Short Shot Injection Molding Jun 14, 2019
Insufficient injection is also called short shot. Short shot is the phenomenon of partly incomplete at the end of the material flow, or a part of the cavity filled with dissatisfaction, especially the thin wall area or the end area of the the runner when injection molding. When the melt is cooled down without filling the mold cavity, or the melt does not fill completely after running into the cavi...

Analysis of the causes of bubbles in injection molding products Jun 14, 2019
The gas of the bubble (vacuum bubble) is very thin and belongs to the vacuum bubble. In general, if a bubble is found at the moment of mold opening, it is a gas interference problem. The formation of vacuum bubbles is due to insufficient filling or low pressure. Under the rapid cooling of the mold, the fuel at the corner of the cavity is pulled, resulting in a volume loss. Solution: (1) Increase t...

Analysis of the Causes of Poor Surface Gloss of Injection Molding Products Jun 28, 2019
The surface gloss of the injection molding is poor, and there are two main reasons for the overall transparency. First, the mold surface is not polished well, and the second is that the melt is cooled prematurely. The specific solution is as follows: (1) Increase the material temperature, injection pressure and speed, especially mold temperature. The mold temperature has a significant effect on th...

The short shot checkpoints Jun 28, 2019
The short shot checkpoints As mentioned that, when the melt is cooled down without filling the mold cavity, or the melt does not fill completely after running into the cavity, it is called the short shot injection molding. We analyse the reasons of short shot. So today let’s discuss how to improve the insufficient injection. Here lists short shot checkpoints: 1) Improper control of process conditi...

There are undercuts around products'4 corner,should we make lifter or slider? Jul 08, 2019
As we know, During mold designing, If the product has inner undercut, we usually make lifter, If has outside undercut, we will make slider, But If it has undercut around the 4 corner, and couldn't be forced demoulding, what should we do? As below picture, should we make lifter or slider? 1. Design Analysis If so, first we will think about to make lifter, but after analyze, If make lifter the...
