J-Lenco maintains a strict quality control program for each customer.
We have a quality control auditor on each shift.
Loss-on-ignition tests are run on each mix to verify resin levels.
Lot control enables us to trace the core back to each raw material.
All incoming raw materials are tested before production approval.
Dog bone strength tests are performed on each mix to verify core strength.
Our quality lab has Hobart lab mixers, Fisher Scientific LOI ovens, Rotap sand screens, Dietert tensile machines, and equipment to do all standard foundry core quality lab tests including physical break tests on cores.
Core box cleaning with Aero-Jet dry ice blaster ensures quality production with minimal wear on your expensive tooling.
