MuCell technology
MuCell technology
Topics
Theoretical part (1st day)
- Principles and differences of physical and chemical foaming
- Influence of foaming on internal pressure in the mold cavity; principles of part filling
- Influence of foaming on thermoplastic material
- Advantages in terms of parts design
- Influence on prices; examples of part calculations
- Process repeatability and quality control
- Screws for foamed parts
- Vibration and ultrasonic welding of MuCell parts
- Mechanical behavior of MuCell foamed parts
- Part and mold design
Practical part (2nd day)
- Testing the influence of setting parameters on the process and molding
- Low percentage of foaming and its effect on part refilling and sinks
- High percentage of foaming and its effect on mechanical properties and weight savings
- Influence of back pressure and screw speed setting on homogeneous gas mixing in the melt – impact on post-blow effect
- Influence of melt and gas retention time on part defects (optimization of plasticizing delay time)
- Influence of cooling time on post-blow effect
- Influence of Roctool technology on post-blow effect
- Influence of injection rate of foamed material on refilling
Basic knowledge of plastic injection technology and peripherals.
This training course is composed of a theoretical and a practical part. Training materials are provided for the theoretical part. The KM80/380CX machine is available and used for the practical training at KUBOUŠEK s.r.o. If the training is required directly at the customer, a machine must be available for this purpose.
