HOW DOES THE QUALITY & INTEGRITY OF ZINC SPIN-CAST PARTS COMPARE WITH CONVENTIONAL ZINC DIE CASTING?
The quality and integrity of Spin-Cast zinc parts are excellent; but a clean very high grade zinc alloy must be used made to correct specifications. The centrifugal force, which distributes metal into the mold cavities, helps to eliminate any entrapped air and fill any shrinkage. Centrifugally Spin-Cast zinc parts have a uniform fine grain structure throughout. If there is any porosity in the castings it is usually visible on the part surface and easily corrected .
