SINSTAR TRI1300A triplex solventless laminating machine is purposebuilt for oneshot threeply composite assignments. Traditional twopass processing has long struggled with the notorious aluminumfoil backpenetration issue: adhesive penetrates pinhole defects on thin aluminum foil during the first lamination step, contaminating foil surfaces and generating dotshaped composite failures.
