Attentions to Car Lamp Mold Polishing Jun 14, 2019
We have done several plastic car lamp molds, polish is very important procedure for this kind of molds. so today we are going to discuss the attentions of plastic auto parts mold polish. 1. For the position of parting line, it should be carefully polished, and at the same time ensure that the appearance of the product. Also, the position of the buckle should also be smooth and smooth, ...

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...

What to consider when designing the plastic mold? Jul 19, 2019
There are some points that should be noticed when plastic mould design: 1.The draft angle should be designed to be more than one degree. 2. It is suitable to select the direction of the projection surface of the plastic part as the direction of forming pressure, which is convenient for the material to fill the cavity, but it is not suitable for the part with high dimensional accuracy and the axis ...

The advantages of the two-stage ejection of the mold Jun 28, 2019
When we do mold design and manufacture, some big parts requires long ejection stroke, at this time, and the two-stage ejection can reduce the force applied by the ejector pin when it is ejected, thereby avoiding defects in the product. The two-stage ejection is welcomed by the market and it has the following advantages: 1. Mechanical interlock design, safe and reliable, the ejector unit come...

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...
