Then,how to realize it???

1. Material Section:

Materials are the basis of making successful high-quality compression bottle caps. Different models of materials with various functions. If not paying attention to materials features,mixed using would affect the quality of final products.


Even though the same model and series, diverse manufacturers are also with different function.Thus, the best way is sampling and select the suitable ones.


Meanwhile, material storage should be prevented from humidity. Wet materials with high percentage of water, bubbles would occur in bottle caps,which is easy to affect caps appearance and sealing function. In addition, to ensure high-quality bottle caps,

manufacturer should use new material to make caps but no mixing with recycling materials, especially dirty and waste materials.


In addition, multi-recycling materials would damage cap moulds,and reduce service life. Besides, reheating makes materials in lower performance, then influence bottle caps quality.

2. Equipment Section:

This is an essential part to produce high-quality products. With the development of compression moulding technology, all kinds of CCM manufacturers appear in domestic market. However, some are only chase low cost but not satisfy food-grade standard. Meanwhile, bottle caps are products required high precision, durable moulds with high accuracy are obviously important.


Jeepine CCM production line achieve intelligent and full automatic production, then realizes high sanitation requirement, this would help bottle caps manufacturers to gain orders from high-level customers.

3.  QC Section:

This is also an important part to product high-quality bottle caps. Nevertheless, final products will tell and win the trust from customers. In a sense,unqualified QC may lead to loss in the game. Therefore, QC plays an essential part in high-quality cap compression moulding. On the one hand, training skillful QC staff. On the other hand, advanced on-line inspection system are necessary section,which may greatly guarantees the caps’ quality fully.
