CASTING VS INJECTION MOLDING—WHICH METHOD WORKS BETTER?
Totally relate to the budget concerns—sometimes those upfront costs for injection molding just aren’t realistic, especially for smaller projects. I’ve found casting gives me a bit more flexibility with custom finishes, though yeah, the cleanup can be a pain. For unique or low-volume pieces, that tradeoff often feels worth it.

That’s pretty much been my experience too—casting is just more forgiving when you’re working on something that needs to look a certain way or has odd geometry. The cleanup and post-processing can be tedious, but sometimes it’s the only way to get the surface detail I want.
One thing I keep running into, though, is dimensional accuracy. With casting, I always seem to be chasing tolerances, especially if I’m working with a material that shrinks unpredictably. Have you found any tricks for keeping things consistent from piece to piece? Or do you just accept that there’ll be some variation and build that into your design?
On the flip side, injection molding is fantastic for repeatability—once you’ve got the mold dialed in, every part is basically identical. But like you said, those upfront costs are brutal for small runs. I’ve tried 3D printing molds for short-run injection molding, but the results are kind of hit-or-miss depending on the complexity.
Curious if anyone’s found a sweet spot where hybrid approaches make sense? Like maybe casting for prototyping and then switching to injection molding if the demand picks up? Or does that just end up doubling your tooling headaches?
CASTING VS INJECTION MOLDING—WHICH METHOD WORKS BETTER?
You’re definitely not alone with the dimensional accuracy headaches in casting. I’ve had to accept a bit of variation and just design around it, especially when working with concrete forms—sometimes you just can’t fight the material. That said, I think your idea of using casting for prototyping and then moving to injection molding as demand grows is spot on. It’s not always seamless, but it saves a ton on upfront costs and lets you refine the design before committing big money. Tooling headaches are real, but honestly, they’re a sign things are scaling up—which is a good problem to have.

I get the appeal of switching to injection molding as things ramp up, but honestly, I’ve found casting works just fine for small runs—even for end-use parts. The setup is so much simpler. Sometimes the hassle of designing around those tiny variations is less work than dealing with the upfront costs and lead times for molds. Maybe it depends on how picky you need to be with tolerances?

I hear you on casting being simpler for small batches. For me, though, when I’m specifying custom hardware or decorative elements for interiors, injection molding’s consistency can be a lifesaver. I’ve run into issues where slight casting variations made installation tricky—especially when parts need to align perfectly. The upfront investment for molds is steep, but if you’re after a really polished, repeatable look, it can pay off. Guess it comes down to how much wiggle room you have in your design and budget.
