Flexible PU Foam Slabstock Continuous Foaming Line SAB-CF13
The Flexible PU Foam Slabstock Continuous Foaming Line SAB-CF13 is designed for factories that need high-capacity, standardized, and repeatable production of flexible PU foam slabstock blocks. It is suitable for continuous production projects where metering, mixing, material distribution, conveying, and foam forming must stay synchronized during long-term operation.
Suitable for projects such as:
- New flexible PU foam slabstock production plants
- Mattress or furniture factories building in-house foam block production
- Existing foam factories expanding slabstock foam capacity
- Continuous foaming line replacement or upgrade projects
- Foam block supply projects for downstream cutting, mattress foam, furniture foam, packaging foam, cleaning sponge, bra foam, shoe material foam, sports mat foam, soundproof foam, and other flexible PU foam applications
Sabtech configures the line according to:
- Target foam products and density range
- Formula system and component requirements
- Color and additive needs
- Planned output and production rhythm
- Factory layout, line length, and curing space
- Downstream cutting and foam block storage capacity
- Budget and future expansion plan
SAB-CF13 is supplied as a complete continuous foaming system, covering raw material feeding, raw material temperature control, metering, high-speed mixing, overflow trough and traversing discharge, foam rising and forming, conveying, ventilation, and block cutting.
Based on the customer’s actual production project, Sabtech helps match the component system, tank layout, metering system, foaming structure, and supporting equipment, so the line can better fit real production conditions instead of following one fixed standard setup.
Key Features and Practical Production Value
1. Up to 350 kg/min Output for High-Capacity Slabstock Production
SAB-CF13 supports a maximum output of up to 350 kg/min. It is suitable for factories with enough curing space, cutting capacity, transfer flow, and block storage conditions to support high-volume flexible PU foam slabstock production.
2. Two Foaming Discharge Methods for Different Foam Widths
- The foaming section can be matched with either an overflow trough or a traversing head according to the required foam width and product result.
- Overflow trough is more suitable for wider foam production, usually around 2000–2400 mm, and can support foam height up to about 1200 mm.
Traversing head is more suitable for foam width around 1000–2000 mm, especially when finer hand feel and more even cell structure are required.
3. Servo-Driven Mixing Head for More Accurate Speed Control
The main mixing head uses a 45 kW servo motor with a 0–6000 rpm speed range. Servo control allows more accurate speed adjustment during continuous foaming, helping the mixing speed better match different output rates and formula conditions.
4. Adjustable Side Boards and Multi-Section Fall Plate for Forming Control
The side boards can be adjusted within the 1.5–2.5 m width range, while the fall plate uses multiple adjustable sections. This helps match different foam widths and improves control over foam flow, rising rhythm, and slabstock forming.
5. Mitsubishi PLC Control for Synchronized Line Operation
The Mitsubishi PLC system controls formula output, metering pump operation, conveyor speed, fall plate height display, line status, and fault feedback. This helps operators monitor key production points and keep the continuous foaming process coordinated.
6. Raw Material Temperature Control Before Metering and Mixing
The heating and cooling unit controls the temperature of main material working tanks before metering and mixing. Stable raw material temperature helps maintain more consistent viscosity, flow condition, metering accuracy, and reaction behavior.

Need Help Choosing The Right Continuous Foaming Line?
Before confirming the SAB-CF13 configuration, please check whether your project conditions can match continuous flexible PU foam slabstock production.
To recommend a suitable line configuration, Sabtech usually needs to know:
- Target foam products and density range
- Planned foam width and foam height
- Expected output and production frequency
- Formula system and component requirements
- Color, additive, or special material control needs
- Workshop layout, available installation space, and line direction
- Curing space and foam block storage area
- Whether you need cutting, transfer, or conveying equipment after foaming
- Whether the project is a new factory, factory expansion, or existing line upgrade
Based on this information, Sabtech can help judge whether SAB-CF13 fits your project and how the metering system, tank layout, foaming method, cutting section, and supporting equipment should be configured.
Contact Sabtech to confirm the suitable continuous foaming line configuration for your factory.
