■ The biaxial eccentric stirring provides data that correlates with JIS and IPC manual methods.
ˑ The method A for phenolic resin gelation time is automated (JIS K6910: 2007).
ˑ The gel time measurement with prepreg is adhered to (IPC-TM-650 2.3.18A).
(1) Put resin on a heat plate and measure the torque when the resin is stirred.
(2) As resin curing progresses, the torque increases. This change is plotted on a graph.
(3) The time when an arbitrary set THR (threshold) is reached is determined to be the gel time.
■ About the heat plate temperature
ˑ It becomes stable and ready for measurement after 5 minutes from powering on.
ˑ The temperature profile can be set.
ˑ Heat plate temperature setting: Room temperature up to 300°C
■ The dedicated software “MADOKA tool” allows for database management and data analysis.
MADOKA tool is software useful for statistical process control (SPC) and statistical quality control (SQC).
It is most suitable for consistent quality control in manufacturing, quality control, research, and other departments of a company.
