UNIQUE R&D PILOT LINE

Product catalog summary

Pilot Line Overview
Brückner Maschinenbau offers a unique technology center for comprehensive R&D in film stretching technologies. The facility is available for rent to customers and raw material suppliers for film and resin development. An online reservation system allows scheduling up to a year in advance, facilitating precise planning of R&D activities and sample production.

Technology Center
The technology center provides a state-of-the-art environment for testing and developing film stretching technologies. It includes various extrusion and co-extrusion setups, allowing for different layer configurations and material outputs.

Resin Supply & Extrusion
The resin supply system includes a conveying system with suction units and pre-dried material bins. The dosing system is gravimetric, supporting multiple components with high accuracy. The extrusion section features twin and single screw extruders with varying diameters and output capacities for different materials like PET and PP.

Die Equipment
The document details several die configurations for different film types, including PP and PET, with specifications on width, die lip gap, and automatic adjustments. The configurations support multiple layers and are designed for specific film properties.

Technical Specifications
The technical specifications cover various components of the pilot line, including:

Inline Coater: Applies water-based coatings on BOPET film with adjustable coating thickness and viscosity.
MDO (Machine Direction Orientation): Includes preheating, stretching, and annealing stages with specific roll dimensions and surface materials.
Corona Treatment: Pre-treatment for cast films with digital IGBT generators and temperature-controlled treatment rolls.
IR Preheater: Used in simultaneous processes with ceramic heaters and specific power consumption.
Casting Unit: Features a chill roll system with temperature control and pinning systems for different materials.
Pull Roll Stand: Equipped with multiple rolls and drives, supporting a wide speed range and thickness measurement.
Edge Trimming: Allows for precise trimming with adjustable positions and blade types.
LISIM® Tenter/TDO: Provides preheating, stretching, annealing, and cooling zones with adjustable fan motors and temperature ranges.
Winder: Supports various winding modes and tension settings, with a maximum film width of 1,270 mm.
