Product Description
Injection Blow Molding Service | High-Precision Plastic Bottle Manufacturing
Intro Paragraph: Injection Blow Molding is a precision plastic manufacturing process used to produce high-quality hollow containers with excellent dimensional consistency and surface finish. The process begins by injection molding a preform around a core rod, followed by blow molding to form the final hollow shape. As an experienced plastic parts manufacturer, we provide reliable custom injection blow molding solutions for medical packaging, cosmetic bottles, and small precision containers. Whether you need non-standard plastic molding or small-batch plastic parts customization, we deliver stable quality, tight tolerances, and efficient production support.
Superior Surface Finish Produces smooth, glossy surfaces with minimal parting lines or flash.
High Precision for Small Containers Ideal for pharmaceutical and cosmetic packaging requiring tight tolerances.
Improved Material Distribution Uniform wall thickness enhances product appearance and structural performance.
Reduced Secondary Processing Precision molding minimizes trimming and finishing requirements.
Our Injection Blow Molding Process
Preform Injection Molding
Molten plastic is injected into a precision mold to create a preform with an accurately formed bottle neck and thread structure.
Blow Molding Formation
The heated preform is transferred into a blow mold where compressed air expands the material against the mold cavity to create the final hollow shape.
Cooling & Stabilization
Controlled cooling systems ensure dimensional stability, smooth surfaces, and consistent wall thickness.
Inspection & Finishing
Finished products undergo dimensional inspection, leak testing, and appearance checks before packaging and shipment.
