Facility Features, Working Principle and Specifications
Facility Description
The Polymer Processing Laboratory at IIT Bombay is equipped with advanced machinery to support research, innovation, and education in polymer science. For external users and internal users also. Key equipment includes a twin-screw extruder with four interchangeable dies (filament, sheet, fiber, and catheter) and a 3D spooler for precise winding, enabling diverse applications such as 3D printing and medical-grade tubing. A single-screw extruder provides efficient processing for simpler polymer formulations. The lab also houses a DSM Micro 5 twin-screw vertical extruder, ideal for small-scale, high-precision material development, and "Haake Mini Jet pro "a mini-injection molding machine for prototyping and testing. Additionally, a pelletizer machine ensures uniform polymer pellet production for compounding and recycling. This facility serves as a hub for cutting-edge research and technological advancements in polymer processing.
Features :
- Twin screw extruder (5cc DSM and Haake Process 11)
- Recirculation (for DSM)
- Use pellet, powder, or melt samples
- Provides efficient sample preparation for mechanical and rheological testing
- Diameter monitor for the strand
- Sheet take-off setup
Working principle :
The majority of polymeric raw materials are available in granules, powder, or flakes form. The transformation from solid to flowable form is carried out by heating the material. Once the material is in a melted state, mold is used to shape the material, and the resulting shape is then fixed by cooling.
Types of material we can use:
- Most thermoplastic materials, including blends, filled systems, etc.
- Size of material we can use: Typically pellets of 1-2 mm size
- Maximum temperature range of machine: 450 degree Celsius
