Multilayer Molding (4 material, 6 layer molding)

01Multilayer Molding (4 material, 6 layer molding)

Multilayer blow molding enables the production of resin fuel tanks that meet the US fuel permeation regulations (EPA/CARB). The tank is composed of 6 layers made from 4 different materials, with an EVOH (barrier layer) at the center to prevent the penetration of harmful substances.
