Product Specs
Model: Custom-made for 3025 bottle mouths
Specification: 26.3*61.5 (we can adjust this to match your exact requirements)
Compatibility: Fits 3025 bottle mouths on all standard PET bottle production lines
Material Choice
We use high-grade stainless steel and precision alloy to make our mandrel heads. Why? Because production lines are tough places—high heat, constant rubbing, and contact with food-safe materials. These materials hold up well under those conditions, so the mandrel head stays reliable and lasts a long time. Every batch of material we use goes through strict quality checks to make sure it resists rust, wear, and high temperatures. That way, it won’t contaminate your PET bottles, and it meets all food safety rules.
How It Works
You can’t run a PET bottle production line without a mandrel head. How it works changes a little depending on which part of the line it’s in, but its main job never changes: keeping preforms and bottles steady while they’re being processed.
Blow Molding Step: In blow molding machines, the mandrel head (we also call it a preform inserter) holds the inside of the preform mouth tight. This keeps the preform from moving around when it’s heated and blown into a bottle shape. If you’re using aseptic blow molding (for sterile drinks), the mandrel head works with UV lamps or hydrogen peroxide sterilizers. It makes sure the outside of the preform is fully exposed to the sterilizer, so it gets completely clean. It also spins the preform fast—so every spot on the outside gets sterilized, no corners missed.
Filling Step: In filling machines, the mandrel head locks bottles into place so they don’t move while being filled. This stops liquid from spilling out and makes sure every bottle gets the same amount of product. For isobaric or atmospheric filling machines, it works with the filling valve to control exactly how much liquid goes in and how fast. That means every bottle is filled accurately—no overfills, no underfills.
Changing Bottle Mouths and Molds: A lot of high-end beverage lines let you switch to different bottle mouths quickly—and the mandrel head is what makes that possible. Swap out the mandrel head for one of a different size, and you can use bottles with different mouth diameters. This cuts down on the time you spend changing molds, so your line can run more flexibly. For example, KHS’s quick bottle mouth change system lets you take the mandrel head off and put a new one on in seconds—just press a spring. That means less downtime and more production time.
Product Advantages
Great Compatibility: We’ve designed this mandrel head to fit 3025 bottle mouths perfectly, and it works with almost every type of PET bottle production line out there. If you need a different size or fit, we can make a custom one for your specific bottle mouths and line setup.
Precise Positioning: We use high-precision machining to make each mandrel head, so its size is accurate to the micron. That means it holds preforms and bottles exactly where they need to be—no shifting, no mistakes during production. The result? Every bottle has the same mouth size, and your product quality stays consistent.
Long-Lasting and Wear-Tough: We choose top-quality materials that resist rust and wear, and we add a special surface treatment to make them even stronger. This means the mandrel head can handle constant friction, high heat, and corrosion during long production runs. It lasts longer, so you don’t have to replace it as often—and that saves you money on maintenance and replacements.
Easy to Install and Replace: We kept the design simple and practical, matching the standard interface of most PET bottle production lines. You don’t need any special tools to install or take it apart—just a few quick steps. That saves you a lot of time when changing molds, so your line can get back to running fast.
Aseptic and Clean: The materials we use meet all food safety standards, and the surface is smooth—so it’s easy to clean. No dirt or bacteria builds up on it, which means your beverage production stays sterile, just like it needs to be.
Where It’s Used
Our 26.3*61.5 mandrel head is made mainly for PET bottle production lines, and it works in a wide range of beverage production setups. Here are some examples of where you can use it:
- Carbonated beverage lines (think Coca-Cola, Pepsi, and other fizzy drinks)
- Non-carbonated beverage lines (mineral water, fruit juice, tea drinks, milk drinks, and more)
- PET bottle lines for liquid foods like edible oil and condiments
- PET bottle lines for cosmetics, daily chemicals, and other products that need precise positioning
It works with most of the popular blow molding and filling machines on the market, and it can pair up with equipment from different brands. No matter what your line uses, this mandrel head will fit and work well.
