Design & Drafting

Medical Equipment Design & Mechanical Engineering Support

Mechanical design, CAD and engineering documentation for medical and laboratory equipment developers — carts and trolleys, enclosures and housings, mounting hardware, laboratory fixtures and design-transfer drawing packages. We work under your quality system and design-control procedures; you remain the legal manufacturer.

Service Overview

A Mechanical Design Partner For Medical Device Teams

Medical device companies carry the regulatory responsibility; what they often lack is mechanical design capacity at the moment a programme needs it. We supply that capacity: experienced mechanical engineers who work inside your templates, numbering, revision and approval workflow, and who produce the models, drawings, calculations and review material your team files in its design history file or technical documentation.

Our scope is the mechanical hardware of medical equipment — the cart, the enclosure, the frame, the fixture, the mechanism — designed with IEC 60601-1 mechanical-hazard requirements in mind (stability, moving parts, trapping zones, mobile-equipment transport) and with sheet-metal, moulding and machining manufacturability built in. Formal testing, risk-management ownership and regulatory submissions stay with you and your accredited partners.

  • Medical carts, trolleys and mobile stands with tip-stability calculation and castor selection
  • Sheet-metal and injection-moulded enclosures: draft, ribs, snap-fits, cleanability and ingress
  • Mounting arms, brackets and frames for monitors, instruments and accessories
  • Laboratory automation fixtures, test rigs and diagnostic instrument mechanics
  • Design-transfer drawing packages, BOMs, tolerance stack-ups and FEA reports
  • Legacy 2D-to-3D conversion and drawing updates for existing equipment (for the rights holder)

What this service is not: We are not ISO 13485 certified and not an FDA-registered establishment; we do not design implants, sterile disposables, drug-delivery or software-led devices, and we do not provide regulatory affairs services.

Engagement Models

Three Ways To Work With Us

Every quote states scope, deliverables, formats, standard, revision rounds and deadline. Prices are quoted per project — in USD, EUR, GBP, AUD or INR.

01

Fixed price per job

Best for defined scopes — a drawing set, a conversion batch, one analysis. You know the total before work starts.

02

Hourly with a cap

For evolving design work where scope is still forming. Hours are logged, reported weekly and never exceed the agreed cap without your sign-off.

03

Dedicated engineer

A named engineer reserved for your work, month by month, on your templates and in your CAD — an extension of your own design office.

Confidentiality & IP

Your Designs Stay Yours

NDA before files

We sign your NDA, or send ours, before a single drawing is shared.

IP assigned to you

Models, drawings and calculations are your property on payment. We keep no rights.

Named engineer

Only the engineers on your job can open your files. You deal with them directly.

Deleted on request

Project data is removed from our systems when you ask, with written confirmation.

Technical FAQ

Questions Engineers Ask Us

Are you ISO 13485 certified?
No. We are a mechanical design-services supplier, qualified under your purchasing controls. ISO 13485 and FDA quality-system obligations sit with the legal manufacturer, and we work inside your QMS rather than claiming our own certification.
Do we need to register you with the FDA or list you with a notified body?
FDA registration guidance lists specification consultants among those not required to register; under EU MDR Article 10(9) the manufacturer controls its suppliers and may need to list relevant subcontractors. Your regulatory affairs team decides how we are recorded; we provide whatever supplier documentation you need.
Can you produce documents for our design history file?
Yes. Design-review packs, calculations, tolerance stack-ups, FEA reports and drawing packages are prepared in your templates and numbering so your team can file them directly; ownership and approval of the DHF remain with you.
Do you design to IEC 60601-1?
We design with the mechanical hazard clauses of IEC 60601-1 in mind — stability, moving parts, trapping and transport — and we state the assumptions used. Formal compliance testing and certification are performed by your accredited test laboratory.
Which medical equipment is a good fit for you?
Carts and trolleys, enclosures and frames, mounting hardware, laboratory and diagnostic equipment mechanics, hospital furniture and design-transfer packages. Implants, sterile disposables, drug delivery and software-led devices are not our scope.
Can you reverse engineer a legacy medical equipment part?
For the rights holder, yes — for example to recreate drawings of an obsolete bracket or housing you manufacture. We do not reverse engineer third-party devices, and fully refurbishing a device for market can make the refurbisher a manufacturer under MDR, which your regulatory team should assess.
How do you handle confidentiality and data retention?
NDA and quality agreement first; named engineers only; files stored on access-controlled systems; retention and deletion per your supplier agreement with written confirmation.
