Why HT Series

Built for Volume Production

Not a demo machine — this is production equipment running 24/7 at client sites. Here's what separates the HT-2L Extrusion Blow Molding Machine from cheaper alternatives:

⚙️

Servo-driven extrusion

Precise wall thickness control across the entire container. Reduces material waste by 8-12% vs hydraulic machines.

🛡️

5-layer co-extrusion die

Barrier layers for chemical resistance. EVOH optional for fuel applications. Common in EU-regulated markets.

🔧

Automated de-flashing

No manual trimming required. Integrated CNC trimming head reduces labor cost and flash reuse rate is higher.

📉

Energy saving mode

Idle power reduction when not extruding. ~15% lower energy cost vs standard machines in the same class.

FAQ

Common Questions

What's the daily output of the HT-2L Extrusion Blow Molding Machine?

For 1000L tanks: approximately 18-22 pcs/day (assuming 90-120s cycle time). For 500L tanks: approximately 30-40 pcs/day. Actual output depends on material, wall thickness, and operator experience.

Can we use recycled HDPE material?

Yes, up to 30% recycled HDPE is acceptable. We recommend using recycled material from known sources to maintain consistent quality. For food-grade containers, virgin material or approved recycled HDPE is required.

Do you offer installation and training?

We offer optional on-site installation and commissioning service (charged separately). Standard package includes video-based operator training and detailed maintenance manual. We can also arrange a Chinese-speaking technician for the first installation if needed.

What's the difference between 3-layer and 5-layer co-extrusion?

3-layer: inner/outer HDPE + adhesive + barrier layer (standard for most chemical storage). 5-layer: HDPE/adhesive/EVOH barrier/adhesive/HDPE — provides better oxygen barrier for fuel and pharma applications. Choose based on your end-use certification requirements.

What payment methods do you accept?

Standard: 30% deposit via T/T, 70% balance before shipment. For orders over $100,000, we can discuss L/C payment terms. We also accept payment through Alibaba Trade Assurance for orders under $50,000.
