Celina can work with customers to manufacture products that are already designed
and private label with the customers company label or we can do the full cradle to
grave concept where the customer brings us an idea and we design, develop, produce
prototypes, first articles, and ramp up in production mode.

AUTODESK AUTOCAD – 2D modeling and design software

AUTODESK INVENTOR – 3D modeling and design software

MPANEL – Form finding and patterning software for tensile structures enables
Celina’s engineers to develop a 3D shape and then panel 2D patterns to construct
the structure.

MATERIALS TESTING
In house quality lab gives engineers the ability to do testing during product development
Celina’s engineers work in conjunction with multiple Licensed Professional
Engineers on projects that need to be certified for wind loads and snow loads. We
can also perform a finite element analysis during the design process to determine
high stress areas.

THERMAL RESISTANCE ASSESSMENT CHAMBER – used to measure the insulating properties of materials, alone or in various combinations. This testing is vital in making our products more thermally efficient. The chamber itself was constructed to be air-tight, thus allow¬ing for a relatively low margin of outside contamination error. Each surface within the chamber is insulated to twice the housing standard; all six sides are coated with R-26 insulation to reduce any temperature leeching through walls, floor, or ceiling. 

The process of testing a material’s thermal properties starts by setting up the material(s) to be tested as a barrier between the two sides of the chamber. One side of the chamber is equipped with a heater, and the opposite an 800 watt air conditioning unit. Each side of the chamber is then monitored and kept at specific temperatures, with the energy expended in maintaining the temperatures measured and documented. 

Energy used to maintain temperature on the “internal tent” side of the chamber is recorded in watt hours, and is compared to the energy expenditure used on an array of different material and insulation arrangements to ultimately find the best selection of materials for our desired purpose. 

Basic testing can range from 90 minutes to 8 hours, though all testing has an unlimited upper duration limit. Due to our ability to test materials with controlled thermal levels for any duration, we can not only test the initial thermal efficiency of materials and products but also how this will affect the materials in the long term, and how lengthened intervals affect the efficiency. By design, the entire time required from the conclusion of one test and test start of another (full tear down to complete set up) is one hour. 

By testing many different materials and combinations, we can then conclude which materials are best suited for the project at hand.
