Our boss switched how we dry sand molds before casting. Now we use fans instead of waiting overnight. Some say it speeds up jobs and works fine. I've seen more cracks and think it risks quality. What's your method for drying molds?
I've had lower back pain for months from bending over molds all day. Tried a new posture trick. Keep your feet wide when lifting heavy stuff. Engage your core too. It sounds basic but it works. My pain is much less now. I can work longer without hurting. Also do quick stretches during breaks. Focus on hamstrings and lower back. Takes two minutes. Makes a big difference. Give it a shot if you have similar issues.
