Preliminary and Detailed Design

Part Design​

Through expert experience with the biggest CAD programs in the industry, we can deliver manufacturable drawings and models

Solidworks, CATIA 3DX, Siemens NX

We can also implement a solution to work with any design and analysis software you might be using


We place an emphasis on maintaining efficiency and garnering a cost-effective production and assembly

Assembly solutions for efficient, rapid in the field solutions, or complex composite bonding and fastening solutions

 Advise on sourcing the right hardware or direct the assembly of unique fasteners in a complex multi-part system

Material Selection

We will help you find the best material and process that helps you meet your design goals

Aluminum, steel, titanium, and engineered plastics 

Forging, machining, compression, and injection molding, and 3D printing


For over 30 years, SDA has focused on the design and analysis of composite materials.  We like to share our extensive knowledge with those in industries who are currently using or wish to use composites in their projects. We can advise the right material, epoxy, and layup for your application:

Materials: Fiberglass, Carbon, Kevlar, Aramid, Foam Core, Honeycomb

Fabrication: Pre-preg, Infusion, Wet-layup


We can help  with Fabrication and assembly support to ensure a seamless transition from design to production

Creating manufacturing work orders

Figuring out part re-work dispositions

Onsite manufacturing support

Our network of world-class fabricators can help you find the right manufacturers to turn your parts made to the highest quality.

Product improvement to reduce costs or improve quality

Act as liaison engineers between you and these shops addressing any concerns that may arise 


If you have a product already in production but seem to have recurring issues with failures in the field, we can help.

We have worked with customers to identify root causes of failure and offered solutions that have extended product life and reduced warranty claims

Other Services

Software We Use

We utilize software from Siemens PLM and Bentley Systems for our design and analysis. We partnered with these organizations to provide you with the same advanced engineering products.

Our experience using the software provides us with extensive knowledge to provide high level support to our customers.
