Sintavia designs and additively manufactures critical components for the Aerospace, Defense, and Space industry, including heat exchangers, flow control valves, high pressure ducts, and chassis.
The company’s design engineers are experts in thermal modeling, finite element analysis, computational fluid dynamics, CAD, and conformity testing. Components designed and additively manufactured by Sintavia are lighter weight and better performing than traditional parts.
AM has long been recognized as a natural production process for heat exchangers, given AM’s ability to create internal passageways in geometries that can’t be manufactured by traditional methods. Sintavia’s expertise in thermal modeling allows it to manufacture both low temperature (up to 250⁰ C) and high temperature (up to 800⁰ C) heat exchangers with increased heat transfer coefficients and minimal pressure drop penalties. These heat exchangers can be manufactured with internal walls of 150 microns or less, and are more than 40% lighter weight than traditional models.
Flow Control Valves
Production of flow control valve assemblies is greatly simplified via AM, with shorter lead times and fewer piece part assemblies. Sintavia additively manufactures flow control valves for commercial aerospace and other key critical industries. These valves have been optimized for fluid performance and weight savings through the use of simulation software.
High Pressure Ducts
Sintavia additively manufactures precision high pressure ducts and duct assemblies for Aerospace, Defense, & Space applications. AM is uniquely suited to meet the difficult design geometries and tolerances of high pressure ducts, and can manufacture assemblies that require fewer component piece parts. Using computational fluid dynamics software, Sintavia is able to design and additively manufacture ducts with optimized flow.
Chassis, particularly those with internal conformal cooling holes, are natural applications for AM, combining traditionally difficult manufacturing aspects. These include thin walls, internal passageways, and unique geometries. By conforming its expertise in both duct and heat exchanger manufacturing, Sintavia is able to design chassis that cool key electronic components at a reduced weight.
Other Part Families
As AM continues to be adopted, Sintavia will continue to work with its customers to develop successful manufacturing strategies for new part families.
Advantages of AM
These designs can offer substantial weight savings and performance in modern aerospace advanced component and assembly design. Each design is manufactured from electronic data generated from CAD files making it a fully direct digital manufacturing process.
Since the design is controlled directly from a CAD file, AM can produce parts that were at one time impossible to manufacture by conventional processes such as cutting, grinding and drilling.
The design is only limited by a designer’s creative abilities. Features such as conformal cooling inserts, functional integration, complex geometries, lattice networks and hollow members are now produced with considerable ease via the AM process.
