Your next model shouldn't be a new engineering project.
H7 turns metal product lines into systems. Every new model, size or site becomes a configuration of what you already have: cheaper to build, faster to launch, stress-tested before it ships.

Why now
Fabrication went online. Engineering didn't.
Laser-cut sheet metal, CNC parts and 3D-printed metal can be quoted online and delivered in days. The engineering behind each new model, size or site still starts from a blank page. That's the part we fix.

What we set up
One system, three parts.
Set up once on your product line, so every product after it costs less to build and less engineering time to release.
Design-to-cost
Cheaper to build
Castings and machined parts redesigned as laser-cut, bent sheet metal. Fewer parts and welds, self-locating tabs, jigs, parts any online fabricator can make.
Product families · design automation
Every new model is a configuration
One parametric parent per family, built on your own design rules. A new model, size or site becomes a row in a table, and the drawings, flat patterns and checks follow.
Structural validation
Stress-tested before it's cut
Hand calculations and FEA where loads matter, sign-off before fabrication, and the drawings and manuals CE marking needs. Every number checked by an engineer.

Sound familiar?
The problems we hear every week.
If one of these sounds like your shop, you don't need more hours of CAD. You need a smarter way to build.
Capacity
Every unit is built by hand, and orders pile up faster than we can weld.
✓
Redesign for parts you can order onlineLaser-cut and bent parts, self-locating tabs, jigs: less hand-fitting, more units from the same team.
Engineering time
We redesign the product for every model or order.
✓
One parametric parent per familyA new size or a new platform becomes a row in a table, with drawings that update with it.
Cost
Our parts cost too much: castings, machining, too many welds.
✓
Cost-down where it countsCastings and machined parts to sheet metal, fewer parts and welds. ~80% lower rotor cost on one turbine impeller.
Growth
Customers keep asking for products we don't make.
✓
A product-line roadmapMarket gaps mapped, grouped into families, a fixed price per family before anything is designed.
Risk
We're about to pay for moulds, but the design isn't ready.
✓
Productize first, tool up laterValidate and sell with online fabricators; moulds only when design and demand are proven.
Ownership
Our engineering is slow and nobody really owns it.
✓

Send a photo, a drawing or a short description of the product that costs too much to build or can't keep up with orders. We reply with where the build loses time and money and what would change it.

About
H7 Engineering was founded by Daniel Hernandez, a mechanical engineer who has spent his career making machines and products cheaper to build.
Daniel spent six years at Turbulent, the Belgian vortex-turbine maker, the last four as Head of Structural Validation, and before that headed the design departments at Dynamictech and BASMELCA. Today H7 works with drafters, mechanical engineers and simulation engineers on product lines for hydropower makers, machine builders and product brands, and manages suppliers in Europe, the US and China.
