During the processing of plastic bottle caps, there are many factors that will affect the processing effect of size. For the factors that affect the size of plastic bottle caps during customization, you may wish to discuss with usPlastic bottle cap manufacturerLet’s take a look together!
Factors that affect size are as follows:
1. Keep the pressure and time
Through the analysis of the test data, as the holding time increases, the weight of the bottle cap gradually increases, resulting in a larger size. Similarly, as the holding pressure increases, the weight of the raw material increases, and the weight of the bottle cap will also increase, which will lead to a larger size. becomes larger. During the above process, the density of the bottle cap always remains unchanged.
2. Mold temperature
The higher the mold temperature setting, the worse the cooling effect of the bottle cap in the mold under the same cooling time. The higher the temperature of the cap obtained, the smaller the size of the cap will be after thermal expansion and contraction.
3. Raw material temperature
As the temperature of the raw material increases, if the cooling time remains unchanged, the temperature of the bottle cap obtained will be higher. The bottle cap will naturally cool down after demoulding. Due to the principle of thermal expansion and contraction, the size will become smaller, corresponding to the temperature of the raw material The parameters of injection molding equipment are screw temperature and mold temperature.
4. Bottle cap weight
Through a large amount of test data, as the weight of the bottle cap increases, the temperature of the cap obtained will increase, thereby making the cap size smaller. But theoretically, the increase in the weight of the cap will lead to a larger size of the cap. Therefore, the weight The effect on size depends on how much weight is increased and the extent of the temperature change, as the two cancel each other out.
