H7 Engineering
Product-line engineering

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.

Suppliers in Europe, the US and ChinaCE and ISO 9001 documentationAutomation and tools your team keepsRelease packages any shop can build from
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.

How an engagement runs

From your brief to a roadmap you approve.

Seven steps, the same for a turbine range, a frame family or a line of aftermarket parts. Each one ends in something you can read, check and sign off.

You approve before we design

The family list and the estimate are a proposal: approve, cut or reorder. Only approved families are built.

Estimates come with a range

±20% per family. After the first batch we re-estimate with real numbers. If it runs faster, it costs less.

Open questions on their own track

Research a part depends on is priced separately and only holds back that part.

Ways to work with us

Priced by result, not by the hour.

Every engagement is contracted with H7. You pay for a roadmap, a product family or a lead engineer, never for slow hours.

Lead offerFixed price · finite project

Productization package

For brands and equipment makers with a line to extend or cost down: your product line set up as a system, once.

  • Paid roadmap: gaps, your design rules, families, a fixed price per family
  • Parametric parents and variant tables
  • Design-to-cost for fabrication: fewer parts and welds
  • Validation: FEA, sign-off, CE documents where needed
  • Automation and tools your team keeps

How the package works →

For hydro and equipment teams2–3 days a week

Fractional lead engineer

A senior mechanical lead inside your team without a full-time hire, contracted through H7.

  • Design reviews and sign-off before fabrication
  • Release packages: drawings, BOMs, files
  • Drafters, fabricators and suppliers coordinated
  • Calculations and FEA when a decision needs them

Monthly retainer, 3-month minimum.

Free productization check

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.

Request the check

Projects are quoted at a fixed price after a short call. Retainers are billed monthly. NDA on request.

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.
