Plastic Bottle Cap Injection Mould

If you have your own injection molding machine, and prefer a cap mould to manufacture your own caps instead of buying finished caps, we are happy to manufacture the new mold for you. For almost all plastic caps we are selling on our site, the molds were made by ourselves.

The cap injection mold we can make for you include:
flip top cap mold, shampoo cap mold, condiments cap mold, disc top cap mold, screw cap mold, jar lid mold, child-resistant cap mold, tamper proof cap mold, pull-push cap mold, theft-proofing cap mold, easy tear cap mold, barrel cap mold, laundry detergent cap mold, cooking oil cap mold, wet tissue cap mold and so on.

Let’s walk through the process


Basic information collection

  • cap usage
  • neck size
  • weight
  • dimension
  • sample photo
  • injection machine model


Bottle Cap Design

The next step is to take the basic or idea and workup both 2D and 3D drawing detailing all the features. Following the drawings we then digitize the new cap and render it out for a very close approximation of what the final cap will look like.


Cap Mould Design

After you confirm the cap drawing, we start make mold design based on the cap structure & your injection molding machine parameters.


Cap Mould Manufacturing

Next, we start the mold manufacturing. Every detail will be strictly stick to the drawings.


Cap Mould Trial

Usually we will do twice mold trial at least. At T0 (first time) trial the main purpose is to test mold movement, parts matching situation and tolerance. At T1 trial, we will keep mold continuous running for 4 hours at least, to make sure everything works properly. If testing works well, we will do the lettering (such as recycling symbol, your LOGO) to the mold and send you real samples for final confirmation. This is where your ideal cap becomes a reality.


Water Leakage Test

This is a very import process, we will get every cap made from every cavity of mold well tested with Vacuum Leakage Testing, to 100% ensure you will get the perfect caps.


Mold Shipping Or Mass Production

The last step is deliver the mold to you. We can provide both of air & sea shipment service for you.

Or if you want the caps only, we can do the mass production for you.
