Q

Rough Surface / Pitted Surface

A

This problem is a typical manifestation of rough surface/pitted surface in the RIM process; the core of the solution lies in ensuring the precise ratio and full mixing of the two components, while controlling the reaction temperature and curing conditions within the optimal window. It is recommen...

Q

Too Slow Curing

A

The core of curing abnormality is that the rate and degree of the crosslinking reaction deviate from the optimal window. The adjustment idea is the "three-element method": formulation (precise metering of catalyst/curing agent), temperature (precise control of mold and material temperature), time...

Q

Uneven Mixing

A

RIM mixing quality is the first element determining part consistency. The core control points are: the impingement mixing Reynolds number of the mixing head (to ensure turbulent mixing), the viscosity matching of the two components (to reduce viscosity difference), the accuracy of the metering pu...
