If you’re looking for bottles or any plastic hollow products which are made of HDPE, LDPE, PP, PS, PETG, PVC, EVA, TPE, Nylon material etc, congrats! you’ve come to the right place.
Our factory manufactures over 100 sets of extrusion blow mould annually. We make sure our mold will be compatible with your extrusion blow moulding machine, no matter what brand your machine is.
Let’s walk through the process
Basic information collection
First of all, we need information of you required bottle.
- raw material
- capacity / volume
- neck size
And information of your extrusion blow molding machine.
- double station or single station
- die head number(mold cavity number)
- center distance of die head
- with or without Auto Deflashing
Bottle & Hollow Product 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 printed samples 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 extrusion blow mould.
Extrusion Blow Mould Design
After you confirm the bottle drawing or 3D sample, we start make mold design based on your extrusion blow molding machine parameters.
Blow Mould Manufacturing
Next, we take the drawing to start mold manufacturing.
It usually takes 15 – 35 days to get the mold done.
We will do the mold trial twice at least, and send you final samples for final confirmation. This is where your ideal bottle becomes a reality.
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 bottles / hollow products only, we can do the mass production for you.

What is Auto-Deflashing to Extrusion Blowing Mold?
Auto-Deflashing means the bottle neck and bottom flash are automatically cut on extrusion blow molding machine.
A auto-deflashing blow mold consists of two parts:
- the blow molding part
- the deflashing part
Before you decide to buy blowing mold with auto-deflashing, please check if your extrusion molding machine support this function.
Check below photos to for your better understanding the difference between blow mold with and without Auto-Deflashing.
Two types of Auto-Deflashing
There are two types of Auto-Dflashing, it depends on bottle mouth design. Both types are actuated by pneumatic cylinder.
Watch below videos to learn the difference.
