Anyone familiar with injection molds?

[dray]

I need an injection mold manufactured.

Anyone interested?

Danny, I have a family friend that does it, but they are in Washington. Otherwise, a buddy of mine does micro-welding (laser and tig) to repair tooling. He's in Rancho Cucamonga, and does work for lots of different tool and die makers, I'm sure he could recommend a good place.

Danny,
I have worked with a small injection molding business in the St. Paul area of Minnesota. They can take a sketch of the part you want to mold...get the mold made and run parts. I assume you are looking to make 1000s and 1000s of one particular plastic item. Let me know if you are still looking for help and I can send you the contact information. You can work directly with this business or I can be your local middleman and help you through the details. For my day job I have had them make 30 to 40 molds over the last 10 years.

I am manufacturing an in frame battery box for my e-bike kits and Im no good at 3d.

I almost have the basic 2.5d size but everything needs to be rounded etc.

Danny,
What are the dimensions of the box.
If you are doing a limited run, you might consider doing Stereolithography (aka rapid prototyping). For limited runs, you can avoid the steep initial tooling costs of injection moulding (provided that the box will fit in standard Rapid Prototyping machine).

In either case you can get a price from emachineshop.com. I have used them and they are very cost effective. You download a CAD program that they created, choose the manufacturing method and materials, and then they give you an immediate price.

These might lend themselves to rotomolding or vaccum molding, both of which someone could do themselves. Here are links to wikipedia and DIY versions. I've built a vacuum former...it works pretty well.

Thanks guys for all the input..

Im definitely going to bite the bullet and have injection mold manufactured.

But am going to look into Stereo lithography as well.

Danny, my friend in Washington has a rapid prototyping machine as well. When my dad gets to the shop I will email you his info.

You can do what you want obviously, but an injection mold for these is going to be EXTREMELY expensive. I would advise you to make some vacuum molds and build a vacuum former for these. Much simpler, quicker and MUCH less money.

Yeah Kevin. I planned to pay quite a chunk of change for the injection mold.

Can you show me some examples of some injection molded clam shell pieces. How do they lock together?

What about inside pieces? To hold my batteries in place. I also have 2 metal pieces that go with it.
One that bolts to the waterbottle holes and one that locks to that so it can be removes and carried in to charge.
