How to Choose Plastic Bottle Caps Production Equipment?

Oct. 18, 2022

There are two main types of plastic bottle cap production equipment: compression molding machines and injection molding machines, each with its own advantages and disadvantages.

Compression Molding Machines


  • High production efficiency
  • Better visual appearance by avoiding gate marks
  • Easy to maintain molds


  • Single function, only ordinary caps can be produced
  • Finished plastic bottle caps cannot be produced at one time
  • Secondary processing may be required after compression molding

Injection Molding Machine


  • Flexible cap style design by purchasing various molds
  • Not only can produce ordinary caps, but also some special functional caps: such as flip-top caps, two-color caps, etc.
  • Not limited to the production of bottle caps, but also other plastic products such as bottle handles
  • High-dimensional precision


  • The production efficiency is lower than that of the compression molding machine
  • The cost of replacing and maintaining the mold is high.
