Choosing a PET bottle cap mould manufacturer

Choosing the best PET bottle cap mould maker for your business is critical to the success of your business. Not only can you ensure product quality, but you can also minimize lead times. 

If you are looking for a manufacturer, you need to consider the following factors:

  • Strict QC system
  • Standard components
  • Weekly or monthly mould process reports

It is crucial to choose an experienced supplier with a proven track record like YuanCheng Mold.


Height h and diameter d are the main dimensions of the PET bottle cap mould. The larger h is, the more stretched the cap will be. Likewise, the smaller the d, the harder it is for the lid to slide out of the groove. But if d is small, the plastic cover may break during ejection. Additionally, the type of plastic plays a vital role in the function and shape of the undercut.

Manufacturer’s history

When choosing a PET bottle cap mould maker, you should look for a manufacturer with a proven manufacturing track record. You can check their work history and consumer reviews to determine their level of expertise. In addition, the material from which the cap mould is made is also essential. A good manufacturer should have an adequate inventory of effective materials and well-trained employees. Using inferior materials can lead to product defects and increase production costs.

Functionality and material of cap

When choosing a PET bottle cap mould, consider the type of unscrewing action your product requires. Unscrewing requires the use of special machines and complex cap moulds. It also has slower cycle times compared to other products. Choosing the wrong unscrewing action can cost you in the long run.

The hardness and toughness of the cap mould material is other important factor. The higher the hardness, the better the wear resistance. The amount of carbides in the material also affects hardness and wear resistance. Hardness and strength are essential because most PET bottle cap moulds are subject to harsh working conditions and heavy shock loads. The toughness of the cap mould depends on the carbon content, grain size, and microstructure.
