MuCell technology training

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.
