Aerospace Engineering & Design

DEMGY supports Airbus, Boeing, Embraer, Tier-1 integrators and airline operators from the earliest material-definition phase through qualification and serial production of aircraft interior plastic and composite parts. Beyond manufacturing, the group operates as an approved aerospace design organization: designing, justifying and qualifying parts that fly, not only producing them.

The integration of DEMGY EIS (Germany) adds an EASA Part 21J Design Organization Approval to the group's engineering capability. Combined with the qualification and machining expertise of DEMGY Pacific (USA), programs can be co-developed once and industrialized on the most appropriate site, across a dual-source EU / North America footprint.

A partner that designs, justifies, qualifies and drives the program — not just one that machines a drawing.

Approved Design Organization: EASA Part 21J

The Design Organization Approval (DOA) held by DEMGY EIS authorizes the design and structural justification of flying cabin parts, from customer requirement to qualification. Two collaboration modes are available to OEM and Tier-1 buyers:

• Design-to-specification
  DEMGY Group designs, justifies and qualifies the part from functional requirements through testing.
• Build-to-print
  DEMGY industrializes and produces from a customer-released definition dossier.

 Engineering Disciplines

• Co-development from material definition
  FST-qualified polymer selection (PEI/Ultem™, PEEK, PEKK, PPS, PPSU) against Airbus ABD0031 and Boeing BMS
• Structural analysis & justification
  Static, dynamic and FST compliance, full justification dossiers
• Metal-to-plastic conversion
  Equivalent-function redesign cutting mass and acquisition cost per CS-25 / FAR 25
• Qualification
  Test planning, campaigns, FAI / PPAP documentation, Boeing D6-51991 alignment
• Design for Manufacturing (DFM)
  Manufacturability and design-to-cost optimization from concept

Metal-to-plastic redesign: same function, less mass, lower acquisition cost.

In-House Tooling & Rapid Prototyping

Engineering is backed by in-house tooling and a prototyping team, shortening the loops between design, test and industrialization and securing supply-chain timelines across program ramp-ups.

• Internal mold design and fabrication
  Faster engineering changes across Airbus APQP gates and Boeing SQEP milestones
• Rapid prototyping
  Functional validation for DV/PV phases before qualification
• Industrial FDM prototyping and presérie iterations
• IP & definition-data protection kept in-house

Program Management

The program management organization identifies and manages risk across the full program lifecycle, absorbing workload peaks and holding OEM milestones from concept to serial production.

• Risk management from concept to series
• Milestone compliance
  Airbus APQP gates, Boeing SQEP milestones
• Industrialization & ramp-up management
• Serial support & aftermarket across platform lifecycle (A320neo, A350, B737 MAX, B787)

An organization that holds the milestones and absorbs the rate ramp-ups.

Value Proposition for Aerospace OEM, Tier-1 & Airline Buyers

• Lower program validation risk
  Design authority (EASA 21J) and qualification-ready processes (Boeing Class I & II, NADCAP) accelerate technical approval on B737 MAX, B777X and B787.
• Faster industrialization
  In-house tooling supports rapid engineering changes across APQP and SQEP milestones, securing timelines on A320neo, A350 and B737 MAX.
• Weight & cost savings
  Metal-to-plastic conversion delivers measurable mass reduction and DOC savings for airline operators.
• Single development, dual sourcing
  A part designed once can be industrialized in Germany (DEMGY EIS) or the USA (DEMGY Pacific), de-risking long-running programs.
• Turnkey delivery
  From design through assembled subsystem with FAI/PPAP packages and VMI/CMI line-of-fit logistics.
