Mandrel Head
General Information
This mandrel head with a size of Ø26.3 × 61.5 is used on PET bottle production lines and is designed for bottles with a 3025 neck finish. It is installed in sections of the line where bottles or preforms need to be held and guided during movement.
On high-speed beverage lines, the condition of the neck-handling parts directly affects line stability. If the support at the neck is not steady, problems such as vibration, positioning errors, or unexpected stops can occur. This mandrel head is made to work under continuous operation and repeated cycles.
The product is manufactured by FOSHAN BAIJINYI PRECISE TECHNOLOGY CO., LTD. (BJY), a supplier focused on PET molds and precision components since 2011. Company background and production capabilities are available at www.bjypetmold.com
Basic Specifications
Part Name: Mandrel Head / Core Shaft Head
Diameter: Ø26.3 mm
Length: 61.5 mm
Neck Finish: 3025
Application: PET bottle blowing and filling lines
Dimensional Standard: Industry standard
Material and Surface Condition
The mandrel head is machined from special alloy steel, commonly used in PET production equipment where parts are exposed to long operating hours and frequent contact.
After machining, a surface treatment is applied to improve wear resistance. This helps slow down surface damage during long-term use and keeps the part working reliably over time.
How It Is Used
In the blowing section, the mandrel head supports the inner area of the preform neck. This support keeps the preform stable while it passes through heating and blowing processes. On faster lines, stable neck handling helps reduce vibration and improves overall forming consistency.
During filling, the mandrel head helps keep the bottle positioned correctly under the filling valve. Proper alignment makes filling more consistent and helps reduce splashing or uneven fill levels.
Application Areas
PET bottle blowing machines
High-speed beverage production lines
Aseptic and conventional filling systems
The mandrel head can be used on mainstream PET equipment, including both international and domestic production lines.
Product Characteristics
Suitable for continuous, high-speed operation
Good wear resistance in long production runs
Stable performance under repeated cycles
Compatible with commonly used PET bottle equipment
About BJY
BJY has been supplying PET molds and precision components since 2011. The company operates its own machining and inspection processes and supports custom solutions based on production requirements.
The focus is on providing practical components that work reliably on real production lines, rather than experimental or short-life parts.
