Temperature & Pressure in Plastic Injection Molding ...

Mold Temperature. Compared to melt temperature, mold temperature has a more serious influence on the finished product. For amorphous polymers, molded-in stress is lessened when a higher mold temperature is utilized for production. Mold temperature is a relevant factor in determining the extent of crystallinity in polymers. Crystallinity is incorporated into certain properties like creep resistance, fatigue resistance, wear resistance, and the dimensional stability during high …

Mold temperature in plastic molding - Injection molding ...

Many plastic molding, especially engineering thermoplastics, operate at relatively high temperatures, such as 80 degrees Celsius or 176 degrees Fahrenheit. If mold is not insulated, heat lost to air and injection molding machine can easily be lost as much as shot cylinder.

What is the influence of mold temperature on injection …

Higher mold temperature means lower flow resistance. On many injection molding machines, this naturally means faster flow through the gate and cavity, because the injection flow control valve used does not correct this change, and faster filling will cause a higher efficiency in the runner and cavity pressure. It may cause flash burrs.

Top 3 Plastic Injection Molding Temperature-Induced ...

Defined: Plastic injection mold warpage is when the intended shape of the molded part is distorted during the cooling process, causing the part to fold, bend, twist or bow. Cause: Mold warpage is often caused by insufficient mold temperatures. If the mold temperature is too low the molecules will solidify prior to packing and at different rates.

Injection Mold Design

The shot volume or injection pressure is not sufficient. Injection speed is so slow that the molten plastics becomes solid before it flows to the end of the mold. Solution Apply higher injection pressure. Install air vent or degassing device. Change the shape of the mold or gate position for better flow of the plastics.

The Need for Temperature Control in Plastic Injection Molding

Oct 07, 2019 · Step 2: Cooling. After injection, the molten plastic is cooled at a specific rate while the material hardens. In most cases, water or coolant will be cycled through the mold to lower its temperature. Temperature control can be achieved by integrating a cooling system with an industrial chiller for injection molding.
