Nowadays literally all humankinds use plastic products 24/7 all over the world. It is super easy to get access to all kinds of plastic products. Thus, here’s the question, have you ever think of how does these plastic products been manufactured? Co Extrusion Blow Molding Technology(EBM), is one of the answers to this question.
CO Extrusion Blow Molding (EBM) is one of the most widely used techniques in plastic container manufacturing industry to produce varies kinds of plastics, including HDPE, PVC, PP, PC, and is very commonly implemented with multi-layer bottles production.
Co-Extrusion Blow Molding Machine is a machine that implemented the EBM technique for manufacturing all kinds of plastic containers made of HDPE, PVC, PP, and PC, etc. To be more functional, EBM Machine can be used to product multi-layer bottle such as chemical bottles, agricultural bottles and so on. FS-55PDDT, the latest model from Full Shine Plastic Machinery in Taiwan is the example. To further get more information about FS-55PDDT, please visit the below Youtube Link to have a closer look:
After knowing the manufacturing process of Co Extrusion Blow Molding, you may say what about Injection Blow Molding (IBM)? That’s another dominant blow molding technique in the manufacturing industry. Let us then take a look at the four major differences between EBM and IBM clearly from the below chart:
|EBM Extrusion Blow Molding||IBM Injection Blow Molding|
|Co extrusion||Available||Not available|
|Cost||Low tooling cost but high in unit cost for products less than 150 ml||High tooling cost but low in unit cost for products less than 150 ml|
|Product Outlook||With flash and scraps that products must be trimmed and reclaimed||No flash and scraps,neck finished at a high level of accuracy, Weight control precisely accurate|
|Mold & Product Flexibility||High flexibility of tooling and the molds can accommodate interchangeable neck finishes||Low mold flexibility and is not economical for products over 500ml Part thickness|
|Part Thickness||Depend on how material is stretched during blowing||Depend on the relationship between mold and core|

As per the advantages of choosing EBM for production, its’ benefits are listed as below:
● Low initial mold tooling costs.
● Flexibility of tooling; molds can accommodate interchangeable neck finishes.
● Container sizes can range from less than 30ml to 200 Liter.
● Container shape is not restricted; bottles can be long and flat or have handles.
● Wide selection of machinery; tooling can be specifically geared to package volume requirements.
As EBM is one of the most commonly used way in plastic container production, there are also numbers of industries that would implement this technique. Below are the top six industries:
● Food and Dairy
● Pharmaceutical / cosmetics
● Lubricants / petrochemicals
● Constructing / garden / outdoor supplies
