Your mold. Your asset.
You own the mold
Ownership is entirely yours from the moment the final invoice is settled. We hold it for production runs, but it belongs to you.
We can ship it anywhere
Moving to a different facility? We ship your mold directly to any factory you choose. No restrictions, no holdbacks.
We will not use it while idle
Your mold only runs for your orders. Never used for other clients, testing, or any other purpose while in storage.

What our clients say
Our Guarantee
What we promise on every project
We believe in fair, transparent, and results-driven partnerships. Here’s what you can count on.
No upfront payment until you approve the quote
Getting a quote is fast, hassle-free, and completely risk-free. You won’t pay a dime until you approve the full project estimate.
No extra charges for delays on our end
If we take longer than the quoted hours to complete your project, you won’t pay for the extra time. The quoted hours are the ceiling, not an estimate.
A fully tested, working product
We don’t just build prototypes — we ensure they function as intended before delivery. You receive a working product, not a visual model.
On-time delivery
Your prototype will be in your hands within the agreed timeline. If something changes on our end, we tell you immediately — not after the fact.
No hidden fees in production
We don’t mark up material or production costs. Our entire profit margin comes only from our engineers’ $25/hr rate. Materials are passed through at cost.
US-based contracts and legal protection
We are a US-registered company. All contracts and payments are handled within the US, so there’s no risk of dealing with international disputes or unenforceable agreements.
Milestone approval, every step
You approve CAD designs, prototype photos, and production samples before we proceed to the next stage. No stage begins without your sign-off. No black boxes, no surprises.
Direct engineer access on every project
Your project gets one or two dedicated engineers from start to finish. No sales reps, no account managers, no communication layers — just you and the people actually building your product.
Frequently asked questions
Who owns the mold after it is built?
You do. Ownership is entirely yours from the moment the final invoice is settled. We hold it in storage for your production runs at no charge.
Can you ship my mold to another factory?
Yes. We can ship your mold to any factory worldwide at any time. No restrictions, no contractual holdbacks.
What is the difference between aluminum and steel molds?
Aluminum molds cost less and build faster but wear out after 1,000 to 10,000 shots — best for small batch validation. Steel molds cost more and take longer but last 100,000+ shots — best for confirmed demand and volume production.
How do I get an injection molding online quote?
Submit your design files (STEP, IGES, DXF, or PDF drawings), target material, surface finish, and quantity. We send back an itemized quote within 48 hours.
How long from design approval to first molded parts?
Steel mold manufacturing: 4 to 6 weeks. First article sample review: 1 to 2 weeks. Production run and shipping: 2 to 3 weeks. Total: approximately 7 to 11 weeks from quote approval to delivered parts.
