Frequently Asked Questions

Stretch Blow Molding
Q1
What are the two steps in the PET/ PP pre-form process?

(1) A pre-form is injection molded.
(2) The pre-form is blow molded into the shape of a bottle.

Q2
How does a stretch blow molding machine work?

The injection machine first produces the pre-form. The pre-form must then cool and solidify, at which point it is discharged from the mold. The cooled pre-form is then placed in the stretch blow mold machine to complete the bottle.

In this method the pre-form material is PET/ PP.

Q3
Can you describe the process flow chart of stretching and blowing PET/ PP bottles?

(1) Pre-form heating.
(2) Pre-form is introduced into the mold and closing unit.
(3) Insert the stretching rod.
(4) Stretching and pre-blowing.
(5) Final bottle blowing.
(6) Mold opens.
(7) Finished bottle discharged from the mold.

Injection Blow Molding
Q1
How do injection blow molding machines work?

The process of injection blow molding is used for the production of hollow glass and plastic objects in large quantities. In the injection blow molding process, the polymer is injection molded onto a core pin; then the core pin is rotated to a blow molding station to be inflated and cooled.

This is the least-used of the three blow molding processes, and is typically used to make small medical and single serve bottles. The process is divided into three steps: injection, blowing and ejection.

In this method, the material is HDPE, LDPE, PP, PVC, PS, ABC, Nylon etc.

Extrusion Blow Molding
Q1
How do extrusion blow molding machines work?

In this method material is extruded from the extrusion machine into a tube shape. The material then goes into the mold and closing unit, and air is blown into the mold to force the material tube to expand into the mold wall. After the material is cooled, it is discharged from the mold.

In this method, the material is HDPE, LDPE, PP, PVC, PS, ABC, and Nylon etc.
