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 PET Bottle 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 bottle and render it out for a very close approximation of what the final bottle 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 order the correct bottle or mold.

3 Stretch Blow Mould Design

After you confirm the bottle drawing or 3D sample, we start make mold design based on our extrusion blow molding machine or your machine parameters.

4 Stretch Blow Mould Manufacturing

Next, we take the drawing to start mold manufacturing. It usually takes 10 days to get the mold done.

5 Stretch Blow Mold Trial

Now we can do the mold trial and send you real samples for final confirmation. This is where your ideal bottle becomes a reality.

6 Mold Shipping Or Bottles Manufacturing

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 bottles only, we can do the mass manufacturing for you.

How to choose the correct Stretch Blow Mould?

It depends on your stretch blow molding machine type. There are two types of stretch blow molding machine as follows:

  • Semi-Automatic Stretch Blow Molding Machine: it consists of one blower unit and one heating unit, it requires manual operation to feed the preform into the heating unit, then take the heated preform to the blower unit. The blow mold for semi-automatic machine is simple.
  • Automatic Stretch Blow Molding Machine: it combines preform loading, heating and blowing with continuous action, no need manual operation. The blow mold for automatic machine requires a center distance data according to your machine.
