Hey guys -

New to the forum, molding for a decent amount of time...

Recently took a new position at a mainly CNC shop that purchased two brand new JSW 180 ton machines and all supporting equipment. Their general idea was to near net mold and save time and waste material.

Seemed reasonable... They have an initial aluminum mold, two cavities, "L" shaped parts. Dimensions of each part are 3.75 x 2.0 x .625

They wanted me to sample a wide range of material from ABS, to GF Nylon, various Ultem grades and today, they gave me PEEK 450G and GF PEEK.

They have oil to get the mold temp up, but it's an aluminum base... Am I crazy, or is this a waste of time and going to turn out poorly?

Any input is appreciated.
