300ml Aseptic Blow Mold

How It Handles the Tough Stuff

Weight Consistency is Everything: Inconsistent bottles mess with your filling line and your margins. We grind our cores and cavities to a tight fit. The result is bottle-to-bottle weight you can rely on, keeping your material use predictable and your quality control happy.

Cooling Done Smart: We don’t just run water lines through the mold. We route them to follow the bottle’s shape—closer where the plastic is thick, managing the flow where it’s thin. This balanced cooling means your bottles set up right and your cycle times stay fast. Less warping, fewer rejects.

Aseptic That’s Actually Sealed: The sterile air isn’t an add-on; it’s built into the mold’s DNA. The interface creates a reliable seal when the mold closes, protecting the parison from the shop floor environment. It’s a critical feature for any food, pharma, or cosmetic run where contamination isn’t an option.

Maintenance Without the Headache: We build access into the design. Common wear parts are meant to be replaced with standard tools. Threads are hardened, seals are accessible. When maintenance is due, it’s a straightforward job, not a days-long forensic teardown.

The Numbers You Need

Bottle Output: A clean 300ml aseptic bottle per cycle.

Mold Size: Measures up at 124mm in diameter and stands 381.2mm tall.

Built For: Fitting your blow molding machine without needing a team of engineers to install it.

Where It’s Making Bottles

This 300ml workhorse is on the floor for makers who can’t afford surprises:

Contract Packers in Shandong: Running probiotic and dairy drinks for brands that need guaranteed sterility.

A Dairy in New Zealand: For their extended-shelf-life creamer line, where package integrity is non-negotiable.

Cosmetic OEMs in Guangdong: Filling alcohol-based sanitizers and premium shampoos where clarity and finish matter.

Why Choosing Us Feels Different

We Rebuild Confidence: Got an old mold that’s seen better days? Send it over. We can rebuild it to perform like new, or use it as a reference to build you a modern replacement that fits your current machine perfectly. It often costs less than chasing the original manufacturer.

A Timeline We Can Actually Meet: For a mold like this, we give you a 3 to 5 week window, and we protect it. If something threatens that timeline, you’ll hear from us a full week in advance—not the day before.

Drawings That Are Useful: You’ll get production-ready files. Your team can open them, measure them, and use them for fixtures or maintenance. No broken formats or missing dimensions.

Spare Parts Like Clockwork: When you need a replacement seal, vent insert, or guide pin, it’s not a quest. We keep common parts moving and can get them to you fast, no bureaucratic delays.

Come See It For Real: Our door in Foshan is open. Walk through our 4000+ square meter shop. See the machines, meet the team, and watch how we work. There’s no substitute for seeing it yourself.

How It Runs on Your Floor

You bolt it onto your machine, hook up your lines. The parison drops. The mold closes with a solid, clean seal. Air inflates the plastic against the smooth cavity walls. The cooling system—designed for even pull-down—does its job. The mold opens. A finished 300ml bottle is ejected. And then it does it again. And again. The focus is on that repeatable, reliable motion, shift after shift.
