During the processing of milk caps, there are many factors that affect the size and processing effect. ForCustomized milk lidWhat are the specific factors for the size of the medium impression? The following is shared by Anhui Hengzheng Packaging Technology Co., Ltd.!

1. Keep the pressure and time

Through test data analysis, 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, andMilkThe cap weight will also increase, which will result in larger sizes.

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 raw material temperature increases, if the cooling time remains constant, we obtainMilkThe temperature of the bottle cap will be higher, and the bottle cap will naturally cool down after demoulding. Due to the principles of thermal expansion and contraction, the size will become smaller. Corresponding to the raw material temperature, the injection molding equipment parameters are screw temperature and mold temperature.

4. Bottle cap weight

along withMilkThe weight of the bottle cap increases, and theMilkThe cap temperature will increase, making the cap smaller in size. But theoretically, an increase in cap weight will result in a larger cap in size. So the effect of weight on size depends on how much the weight increases and the range of temperature changes , because the two will cancel each other out.
