PU injection machine for thermal barrier aluminum profile is popular in America

the whole line includes knurling machine, injection machine , cutting machine

process method:

1. knurling the notch of aluminum profiles, make teeth, increase fraction

2. injecting PU in notch of aluminum profiles

3. cut the aluminum metal web under PU, let aluminum profile connected just by PU, stop heat transfer from outside to inside

why we use PU for stopping heat transfer?

because thermal conductivity of PU is very low, heat or cold is not easy to transfer through PU
