Extrusion Blow Mould

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 300 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.

> You may also need Stretch Blow Mould (for making PET bottles), Preform Mould or Cap Mould.

Let’s walk through the process

1 Basic Information Required

First of all, we need basic information of the bottle you required.

Bottle / hollow product information needed:
  • raw material
  • capacity / volume
  • shape
  • neck size
  • weight
  • dimension
  • application
Your extrusion blow molding machine information needed:
  • double station or single station
  • die head number(mold cavity number)
  • center distance of die head
  • with or without Auto Deflashing

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 & 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 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 extrusion blow mould.

3 Extrusion 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 Extrusion Blow Mould Manufacturing

Next, we take the drawing to start mold manufacturing. It usually takes 30 days to get the mold done.

5 Extrusion Blow Mould 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 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 bottles / hollow products only, we can do the mass manufacturing for you.

What is Auto-Deflashing to Extrusion Blowing Mold?

Auto-Deflashing means the bottle neck and bottom flash are automatically cut by extrusion blow molding machine.

A auto-deflashing mold consists of two parts, the blow molding part and the deflashing part. Before you decide to buy blowing mold with auto-deflashing, please make sure your extrusion molding machine have the auto-deflshing device.

Two types of Auto-Deflashing for extrusion blow mould

There are two types of Auto-Dflashing, it depends on bottle mouth design. Both types are actuated by pneumatic cylinder. Watch below video to learn the difference.

A type: Rotating cutting

In this type of auto deflashing, the bottle top mouth has a wide thickness, and when bottle forming inside mold, it comes with a flash bubble on top. The cutting knife will rotate a circle to cut the whole bubble down.

B type: Punching cutting

In this type of auto deflashing, the bottle mouth width is smaller and the internal edge and wall are in same plane, when bottle forming inside mold, there is a open flash on top. The punch knife move forward to cut the flash down.
