Multilayer co-extrusion blow molding is the technology of making hollow container by blowing molding.
It uses more than two extruders to melt and plasticize the same or different plastics in different extruders.
And then compounding, extruding and forming multi-layer concentric composite parison in the die.
Its basic process principle is same with the single layer blow moulding technique. Only the moulding equipment use several extruders to plasticize different kind of plastics.
Control the integration and bond quality of plastics layers is the key to the multilayer co-extrusion blow molding technology.
Multilayer co-extrusion blow molding is developed to meet the needs in some industries with some special requirements.
Such as the airtightness and corrosion resistance in pharmaceutical, food and Industry.
Multilayer Co-Extrusion Blow Molding Characteristics
Multilayer co-extrusion blow molding hollow products are produced by extruding several different raw materials into hollow products through multi-layer die head.
To achieve the barrier performance of the container to external substances.
Adopt coextrusion blow molding, compound a variety of polymers together. Forming the multi-layer containers.
The advantages can be summarized as follows:
- Improve the impermeability
- Improve the products performance. Such as strength, stiffness, softness, heat resistance, transparency and size stability
- Improve the surface performance of products. No stripe, no speckle, no scratch. More smooth, more clean
We are factory in Dongguan China. We are doing this blow molding machine for more than 20 years since 1999. we are the biggest factory on blow molding machine in East China.
Sorry, for now, we only offer blow molding machine. we don’t offer any blow molding products or blow molding service.
for small size machine, delivery time in 2 month. for middle size machine, in 3 month, for large size machine, in 4 or 5 month.
1 year warranty time, but service for lifetime of this blow molding machine. sure, install the machine after shipping on our side.
