Specifications

Model: Core Shaft Head

Dimension: ø26.3*62 (Outer Diameter: 26.3mm, Length: 62mm)

Applicable Equipment: Bottle blowing machines in PET bottle production lines

Precision: High-precision processing, dimensional tolerance ≤ ±0.005mm

Material

The core shaft head ø26.3*62 is made of high-quality alloy steel (material can be customized per customer’s requirements). It goes through professional heat treatment, which ensures stable performance, excellent wear resistance and a long service life during long-term high-speed operation.

Working Principle

As a key component of bottle blowing machines, this core shaft head plays multiple vital roles in PET blow molding to keep the bottle forming process smooth and efficient.
First, it secures and supports the preform during blow molding, holding it in the correct position and posture inside the mold. This stops the preform from deforming or shifting due to gravity or air flow, building a solid base for the following forming steps.
Second, its shape, size and installation position directly impact the preform’s wall thickness distribution. Our precise design adjusts how much the preform stretches and expands during blowing, making sure the bottle wall thickness is even and the product quality is consistent.
Third, it works with the mold to guide compressed air evenly into the preform in the blow-forming stage, making the preform expand quickly into the mold’s shape. Its optimized design eliminates air dead angles and uneven local pressure, lifting up forming efficiency and bottle quality.
Fourth, it assists with filling and sealing in integrated blow-fill-seal equipment. It acts as a guide for filling needles to ensure accurate liquid injection, and shapes and compresses the bottle mouth with the mold for subsequent sealing, guaranteeing the bottle’s excellent sealing performance.
Last, its specially designed top trims, chamfers or embosses the bottle mouth, improving the mouth’s smoothness and precision. This enhances the bottle’s sealing and compatibility in filling, sealing and daily use, and reduces the risks of bottle mouth defects and leakage thanks to the part’s high precision and stability.
