Have you tried tweaking your casting process a bit, though? I get injection molding is usually the go-to for precision, but sometimes minor adjustments in mold design or cooling methods can really help with shrinkage and warping. Had a similar headache with some custom handles I casted—ended up experimenting with different alloys and cooling times. It wasn't perfect, but it got pretty close. Still, if you're chasing super tight tolerances, injection molding probably saves you from pulling your hair out...

Yeah, tweaking can help a bit, but honestly, I've found casting to be pretty finicky when you're after tight tolerances. Injection molding's usually less hassle if precision matters...though it ain't cheap.

True, injection molding can save headaches when precision's key, but don't underestimate casting just yet. I've seen some pretty impressive results from hobbyists who got creative with mold materials and cooling setups. Sometimes a little experimentation and patience can surprise you—plus, there's something uniquely satisfying about nailing tight tolerances with a DIY approach. Keep at it, you're probably closer than you think.
Good points here, but I'm wondering about durability over time. Injection molding usually gives you pretty consistent strength and finish, but how does DIY casting hold up long-term? I've seen some hobbyist castings look great initially, then warp or degrade after a year or two—especially outdoors. Curious if anyone's had better luck with specific materials or techniques to keep DIY casts stable over the long haul...
I've had mixed results with DIY casting myself. Honestly, the key seems to be in the material choice and prep work. I've seen epoxy-based casts hold up surprisingly well outdoors—provided they're UV-stabilized and properly sealed. On the flip side, cheaper resins or improper curing can definitely warp or yellow over time. Makes me wonder if anyone's experimented with additives or coatings specifically designed to boost weather resistance...?
