Product Overview

This HS008-Ⅲ AI valve bag making machine is a high-speed, precision block bottom valve sack production system designed for cement, chemical, fertilizer, and building material packaging. Powered by the Schneider (France) control system, it delivers super computing power with millisecond scanning cycles, surgical-level precision (2kHz servo response, <0.01mm dynamic error), 24/7 reliability in harsh environments (-20℃ to 60℃ with anti-interference design), and intelligent energy saving (10-30% reduction). The machine features innovative bag opening technology combining adsorption with conveying, a unique heat sealing system with adjustable nozzle width (1mm increments), independent servo motors for all functions, and a standard AI visual inspection system with <0.05% missed detection rate. HAOSEN sources this machine from China's top bag-making equipment factories, verified for patent clearance — completely independent invention, no risk of patent litigation.

Notes on Suitable Ingredients: PP/PE tubular woven fabric (double-sided or single-sided coating), with valve sticker and bottom sticker.

FAQ

Frequently Asked Questions

What is a PP/HDPE flat yarn extrusion line?

A PP/HDPE flat yarn extrusion line is a complete production system that converts polypropylene or HDPE resin into high-strength flat yarn. It integrates extrusion, filtration, film formation, slitting, stretching, annealing and winding into one continuous process, producing yarn for woven bags, jumbo bags, geotextiles and industrial packaging.

The line processes both polypropylene (PP) and high-density polyethylene (HDPE) resin, and can also handle recycled PP/HDPE material and masterbatch additives for coloring and UV stabilization depending on your configuration.

Flat yarn is the base material for PP woven bags, FIBC jumbo bags, cement and fertilizer bags, geotextiles, tarpaulins, carpet backing and other industrial packaging. The yarn is woven on circular or flat looms into fabric used across these applications.

HAOSEN offers multiple models. The 500kg/h series suits large woven bag factories, while the dual extrusion series reaches up to 1000kg/h for high-capacity production. Output is customized to your required denier range, yarn width and working hours.

How much energy does the machine consume?

Yes. HAOSEN configures each line around your target output, flat yarn width, denier range and application. We customize extruder size, die width, stretching ratio and winding configuration to match your production requirements.

A flat yarn extrusion line can typically be installed and commissioned within 4 to 8 weeks depending on project scope, site readiness and customization level. Our engineers remain on site until stable production is achieved.

Yes. HAOSEN provides remote technical support with PLC-connected diagnostics, spare parts service and ongoing engineering assistance after delivery to keep your extrusion line running at peak performance.
