600ML Blow mold

High-Precision Molding

We design and machine our molds to tight tolerances. The result is bottles with consistent shape, accurate dimensions, and clean surfaces—exactly what you need for high-end beverage or pharmaceutical applications. Fewer defects mean less waste and higher line output.

Quick Changeover Capability

Changeovers happen fast. The mold structure supports rapid switching between different bottle shapes, diameters, and heights. That means less downtime, more flexibility, and the ability to react quickly when your product mix changes.

Efficient Cooling System

Cooling channels are laid out to remove heat evenly and quickly. Cycle times come down, production goes up, and energy use stays in check—without compromising bottle quality.

Durability and Stability

We use quality materials like aluminum alloy and steel, paired with precision machining and surface treatments. The molds resist corrosion and hold up over long production runs, giving you reliable performance day after day.

Strong Compatibility

The mold is specifically designed for Tech-long blow molding machines, ensuring stable operation and reliable performance.

Energy Savings

By optimizing the mold structure and the blowing process itself, we reduce high-pressure air consumption. Lower energy use adds up to real savings over time.

Foshan Baijinyi Precise Technology Co., Ltd. (BJY) started in 2011. Today, we’re known in the industry for consistency, speed, and long tool life.

High Precision and Consistency

We hold tolerances tight. Bottles from our molds match in size, shape, and volume—batch after batch. For brands that demand consistency, that’s non-negotiable.

Fast R&D and Customization

We take on over 1,000 new projects a year. Need a custom shape? A special neck finish? A mold for a tricky bottle design? We move fast. Our lead times are about 20 days shorter than what you’d typically see from international suppliers.

Advanced Materials and Process Technology

We choose materials that hold up—wear-resistant, corrosion-resistant alloys. Combined with smart cooling design and reinforced mold structure, our tools regularly hit 10 million cycles. That’s well above industry average.

Stretch blow molding happens in two stages.

First, the preform—26.5 g with a 2925 neck—goes through an infrared oven. It’s heated to the right temperature so the material will stretch evenly.

Then it moves into the mold. A stretch rod pulls it lengthwise while compressed air pushes it outward against the cavity walls. The bottle takes its final shape in milliseconds. Right after that, our cooling system pulls the heat out fast, locking in the shape and keeping the material strong and clear.

We build these molds primarily from A6061 aluminum alloy. It conducts heat well, resists corrosion, and keeps cooling efficient.

On the process side, we use:

High-speed CNC machining for micron-level accuracy

Surface treatments that add wear and corrosion resistance

All of it adds up to a mold that runs longer and holds its geometry over millions of cycles.

This mold is designed for:

Bottled drinking water

Beverages

Pharmaceutical containers

Personal care products

It’s especially suited for high-speed rotary lines—particularly Tech-long equipment—where uptime and consistency matter most.

Not every bottle is standard, and we don’t expect yours to be. Our engineering team works directly with you to develop molds for custom shapes, volumes, or functional features. We keep development cycles short, so you can get to market faster.
