How to prevent the mold can not be opened? Apr 16, 2021
In order to prevent the mold can not be opened, the following preventive measures should be taken: 1. Calculate the clamping force correctly, not the bigger the better. 2. Do not keep the high pressure mode locking state when the machine is shut down. 3. In case of power failure in the mode locking state, it is necessary to deal with it in time. It is necessary to loosen the crosshead nut after a ...

What are the conditions for AS injection molding? Apr 16, 2021
What are the conditions for injection molding? 1. Pay attention to the design of the formed products if there is the possibility of pot cracking.For special cases, use more than 1° of retraction incline, and pay attention to the mold should not have low sag part. 2. The forming shrinkage rate is about 0.45%, the heating temperature is 170~310℃, the hot air dryer is used, the drying time is 2~3 hou...

The technique method of reducing the shrinkage way in plastic mold processing Apr 23, 2021
The technique method of reducing the shrinkage way in plastic mold processing Shrinkage in the thicker parts of the plastic mold, such as ribs or protrusions, is more severe than in the adjacent areas, because the cooling rate in the thicker area is much slower than that in the surrounding area.Different cooling rates lead to the formation of depressions at the joint surfaces, known as shrinkage m...

The reason analysis that injection molding product cracks? Apr 23, 2021
The reason analysis that injection molding product cracks? When the product is produced, there are cracks, including filamentous cracks on the surface of the product, micro-cracks, top whiteness and resulting in product loss. According to the cracking time, demoulding cracking and application cracking are mainly caused by the following aspects. (1) Processing 1. Increased processing pressure, too ...
Benefits of perform mold flow analysis Apr 29, 2021
We perform a complete mold flow analysis on every new injection mold we build. The mold flow software today is very accurate at predicting potential injection molding problems and bring benefits. By optimizing the cooling circuitry valuable cycle time can be reduced. Warpage data can be used to play critical features steel safe or modify the part model by adding windage. Injection molders and...

TPE overmolding for bonding to PC Apr 29, 2021
Couple of things I usually recommend to get good bonds of TPE (Thermoplastic Elastomer) and PC: a. Melt temperature is critical for a good bond. The melt temperature for overmolding is usually 390- 440F for overmolding over polycarbonate. The TPE has to be over the minimum melt temperature of 390F from start to finish. If it goes below this melt temperature at any point, the TPE will not bond to t...
