Description
If you run a straight-line blow molding machine, the mold has to follow the linear indexing motion exactly—heat, blow, eject, repeat. Our linear bottle blowing mold is built for that rhythm. We machine the cavity plate and pitch spacing to match your machine’s heating tunnel and clamp stroke, so the preform does not drift off-center during the blow stage.
Why Customers Keep Reordering
- Linear system design: Each cavity sits in a straight row that mirrors the machine’s path. We do not force a rotary cavity layout onto a linear machine and hope it works.
- Independent cavity control: Valves and cooling circuits are separated by cavity where possible. If one station needs maintenance, you can isolate it without stopping the whole line.
- Flexible configuration: Cavity count and spacing are adapted to your machine’s lane width and bottle size. Small pharma bottles and large CSD bottles need completely different pitch and neck-finish specs—we adjust for both.
- Material and cooling: We select the mold steel and cooling channel layout based on your bottle wall thickness and output target. Thicker walls need more even cooling; higher output needs more water flow. We ask those questions up front.
Typical Use Cases
This linear blow mold is commonly used after a PET injection molding machine or an upstream preform supply. The preform drops into the lane, heats through the straight-line tunnel, and blows into a PET bottle mold cavity shaped to your final bottle geometry. We also supply matched PET preform molds if you want the full in-house preform-to-bottle line from one supplier.
Optional Configuration Notes
- Cavity count: optional configuration based on machine lane capacity
- Pitch / spacing: optional configuration to match heating tunnel and clamp stroke
- Neck finish: PCO 1810, PCO 1881, 30/25, 38 mm, or custom
- Bottle volume range: optional configuration
- Mold steel and cooling layout: selected per bottle wall thickness and target cycle
- Compatible with major straight-line blow molding machine brands
What to Send for a Quote
We do not need a 50-page brief. A bottle sample or 3D drawing, your machine brand and lane width, and your target bottles per hour are enough for us to size the cavity count, cooling layout, and pitch. If you already run a rotary blow mold line and want to add a linear machine for smaller runs or different bottle families, tell us—we can keep the neck-finish and blow profile uniform so your downstream labeling and packing equipment does not need retooling.

Description
Product Overview
HEYAN supplies linear blow molds that fit PET bottle production lines. The molds work with blow molding machines from Chinese, European, and other manufacturers.
Speed and bottle quality depend on mold material, cooling design, and machine match. Mold materials are selected based on production volume and bottle complexity:
– Stainless steel: Recommended for high-volume, long-life production (abrasion and corrosion resistant)
– 7075 Aerospace Aluminum: Lightweight, excellent thermal conductivity, suitable for faster cycle times and complex shapes

- Parting line precision: Clean, consistent seam for aesthetics and label adhesion
Applications
- Carbonated beverage bottles
- Still water bottles
- Juice and dairy containers
- Edible oil bottles
- Cosmetic and detergent bottles
- Wide-mouth jars and containers
FAQ
Q1. Which blow molding machines can these molds fit?
The molds fit major Chinese, European, and other international blow molding machine brands. We confirm the machine model, tie-bar spacing, and mounting interface before production.
Q2. What cavity range and bottle volume are available?
Cavity range is 1–14, bottle volume 50 ml–20 L depending on machine capacity. Delivery is 15–25 days from confirmed design.
Q3. How do I choose stainless steel vs. 7075 aerospace aluminum?
Stainless steel suits high-volume, long-life production with abrasive or corrosive contents. 7075 aluminum is lighter with better thermal conductivity, giving faster cycles and suitability for complex shapes — best when cycle time and changeover speed matter more than absolute lifespan.
Q4. Which applications are covered?
Carbonated beverages, still water, juice and dairy, edible oil, cosmetics, detergents, and wide-mouth jars and containers.
Q5. Do you provide design support for new bottles?
Yes. Key design points — uniform stretch ratio, cooling channel optimization, quick-change inserts, venting, and parting line precision — are reviewed with your bottle drawing before we quote.
Selection Guide
Three steps to a confirmed configuration:
- Estimate batch size and bottle complexity — stainless steel for long-run high volume, 7075 aluminum for fast cycles and complex shapes.
- Confirm machine brand/model and bottle volume; this fixes cavity count and mold footprint.
- Check contents (abrasive/corrosive) to finalize material grade.
Delivery & After-Sales Support
- Design confirmation — machine interface, bottle drawing, and target cycle.
- Manufacturing with cooling and venting checks per cavity.
- Factory test and sample check before packing.
- Shipping with mold protection and fitting documentation.
- Start-up guidance and after-sales support.
