Llain Pres
Cyflwyniad Cynnyrch
Taflen Pres yn seiliedig ar gopr electrolytig, sinc ac elfennau hybrin fel ei ddeunydd crai, trwy brosesu gan ingot, rholio poeth, rholio oer, triniaeth wres, glanhau wyneb, torri, gorffen, ac yna pacio. Perfformiad prosesau deunydd, plastigrwydd, priodweddau mecanyddol, ymwrthedd cyrydiad, perfformiad a thun da. Fe'i defnyddiwyd yn helaeth mewn diwydiannau trydanol, modurol, cyfathrebu, caledwedd, addurno a diwydiannau eraill
