Let’s walk through the process

1 Basic Information Required

First of all, we need basic information of cap and your injection molding machine.

  • usage
  • neck size
  • weight
  • dimension (better provide us your bottle neck information)
  • sample (or photo at least)
  • injection machine injection weight & tie bar distance

If you don’t have an idea, we will discuss your needs, purpose and objective thoroughly and provide a concept that will satisfy your situation. We will work with you from the ground up.

2 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. This is where it really starts to come to life.

3D Print Sample Support

If you still got worries about 2D & 3D drawings, we can provide a 3D print sample and send to you via express, so that you can have a closer look of the final design and to ensure you will make the correct cap & mold.

3 Cap Mould Design

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

4 Cap Mould Manufacturing

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

5 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.

6 Water Leakage Testing

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.

7 Mold Shipping Or Mass Production

The last step is deliver the mold to you. We can provide both of air & sea shipment with economical cost. Or if you want the caps only, we can do the mass production for you.
