Product Description

Extrusion Blow Molding Service | Custom Plastic Bottle & Container Manufacturing

Intro Paragraph:
Extrusion Blow Molding is one of the most widely used plastic manufacturing processes for producing hollow plastic products. The process begins by extruding molten plastic into a tube-shaped parison, which is then inflated with compressed air inside a mold cavity to form the final shape. As a professional plastic parts manufacturer, we provide high-quality custom extrusion blow molding solutions for industrial containers, automotive components, bottles, and large hollow plastic parts. Whether you need non-standard plastic molding or small-batch plastic parts customization, we deliver reliable production with consistent quality and fast lead times.


Advantages of Extrusion Blow Molding

Extrusion Blow Molding Types

Continuous Extrusion Blow Molding

This process continuously extrudes molten plastic while molds move in sequence for high-speed production. It is commonly used for bottles, household containers, and packaging products requiring large production volumes.

Typical Applications:


Intermittent Extrusion Blow Molding

In this method, the extrusion process pauses between cycles, allowing better control of larger or thicker products. It is suitable for medium-sized industrial parts and technical containers.

Typical Applications:


Accumulator Head Blow Molding

Accumulator head systems store molten plastic before rapidly releasing it into the mold, making them ideal for large hollow parts with thick walls.

Typical Applications:


Co-Extrusion Blow Molding

This process combines multiple plastic layers into one hollow product, improving barrier performance, durability, and chemical resistance.

Typical Applications:


3D Blow Molding

3D blow molding allows complex curved hollow structures that traditional straight-line extrusion cannot achieve. It is commonly used for automotive and technical applications.
