Injection molding definitely has its advantages, especially if you're dealing with high volumes or client-facing products regularly. But I'd argue vacuum casting still has its place—particularly for smaller runs or custom projects. I've done some decorative hardware myself, and the initial investment for injection molding just wasn't justified in every scenario. Sure, durability and finish quality matter, but vacuum casting can deliver pretty decent results if you're careful with material selection and post-processing.
I've had a few pieces cast that have held up surprisingly well over time, even in high-use areas around the house. Of course, you might get the occasional callback, but if you're meticulous about your molds and materials, it's not as frequent as you'd think. Injection molding is great, no doubt, but it's not always the best fit financially or logistically for every project. Sometimes the flexibility and lower upfront costs of vacuum casting outweigh the benefits you'd gain from injection molding... at least that's been my experience.
I totally get where you're coming from. Injection molding can feel like overkill if you're not doing huge batches.

Exactly my thoughts. I've seen some vacuum-cast decorative pieces in luxury interiors that you'd swear were injection molded—really impressive stuff. With attention to detail, it's surprising how high-end the results can be. Glad someone else appreciates the creative potential there!
That's a good point about luxury interiors—I've noticed some vacuum-cast pieces that genuinely surprised me too. But I'm curious, have you run into any durability issues over time with vacuum-cast decorative elements? I've seen injection-molded items hold up pretty well long-term, but haven't had enough experience yet to know how vacuum-cast pieces age, especially in high-traffic areas or places exposed to sunlight...
I've had a couple vacuum-cast decorative trims around my windows for about two years now. Honestly, they've held up better than I expected, even with direct sunlight. But I did notice one piece near the entryway got chipped pretty easily—probably from my kids throwing shoes around...
"Honestly, they've held up better than I expected, even with direct sunlight."
That's great to hear—especially since I've been considering vacuum-cast trims myself due to budget constraints. Injection molding always seemed a bit pricey for my taste, though I've heard it's more durable overall. But hey, if your trims survived two years of sun exposure and only succumbed to flying shoes, that's pretty impressive in my book. Kids have a special talent for testing durability, don't they? My youngest once managed to crack a supposedly "unbreakable" plastic planter with a frisbee toss... go figure.
Anyway, your experience gives me some confidence that vacuum casting might be a solid compromise between cost and durability. Maybe I'll just keep the shoe-throwing zone away from the windows...
