Product Description

Injection Stretch Blow Molding Service | High-Strength PET Bottle Manufacturing

Intro Paragraph:
Injection Stretch Blow Molding (ISBM) is a high-performance plastic manufacturing process used to produce lightweight, transparent, and durable hollow containers. Before blow molding, the preform is stretched both axially and radially, significantly improving material strength, clarity, and barrier performance. As an experienced plastic parts manufacturer, we provide professional custom ISBM solutions for beverage bottles, water containers, and food-grade packaging. Whether you require non-standard plastic molding or small-batch plastic parts customization, we deliver reliable quality, precision manufacturing, and efficient production support.

Advantages of Injection Stretch Blow Molding

Single-Stage ISBM

Single-Stage Injection Stretch Blow Molding combines preform injection and stretch blow molding in a single integrated machine. This method is highly efficient for smaller production volumes and specialty bottle manufacturing.

Advantages:

Typical Applications:

Two-Stage ISBM

Two-Stage Injection Stretch Blow Molding separates preform manufacturing and blow molding into two independent processes. Preforms are first injection molded and later reheated for stretch blow molding.

Advantages:

Typical Applications:

Our ISBM Manufacturing Process

Preform Injection Molding

High-precision PET preforms are produced with accurate neck dimensions and consistent material distribution.

Preform Heating & Stretching

The preform is reheated and stretched axially using a stretch rod before compressed air expands it into the mold cavity.

Blow Molding Formation

Controlled air pressure shapes the stretched material into lightweight, high-strength containers with excellent clarity.

Cooling & Inspection

Finished bottles undergo dimensional inspection, leak testing, and visual quality checks to ensure production consistency.
