300ml PET Blow Mould for CSD Bottles

What You Can Expect

Designed Around Real Production Conditions

Instead of only focusing on drawing specifications, we pay more attention to how the mould behaves on the machine. Wall thickness distribution, bottle shape stability, and repeatability are all considered during design.

Aluminum That Makes Sense

A6061 is not just chosen for weight reduction. It also helps with heat transfer, which is useful when cycle time matters. Compared to heavier moulds, handling becomes easier too — especially during maintenance.

Surface Finish That Holds Up

The cavity is processed to achieve a clean and consistent surface. This is not only about appearance; it also reduces the chance of defects showing up during high-speed production.

Cooling and Venting — Done Properly

Cooling channels are arranged to avoid uneven temperature zones. At the same time, venting paths are kept simple and effective, so trapped air doesn’t become a recurring issue.

No Worry About Compatibility

If your line is already running, we don’t expect you to change it for the mould. The design can be adjusted to match different machine setups.

How We Look at Quality

We usually don’t judge a mould by a single factor. A few practical checks matter more:

Surface condition should be clean, without marks or corrosion

Dimensions are verified using standard measuring tools

Parting surface needs to close tightly — no leakage

Structure must stay stable during repeated cycles

Trial runs are necessary to confirm bottle forming

Production should remain consistent over time

In short, if it runs well on your machine and keeps running, that’s what we call a good mould.

About BJY

FOSHAN BAIJINYI PRECISE TECHNOLOGY CO., LTD. (BJY) has been working on PET moulds since 2011. Over the years, most improvements we made didn’t come from drawings — they came from solving issues on production lines.

We supply blow moulds, preform moulds, and related components, and we are familiar with different machine systems used in the market.
