The Fiber
SCI utilizes the Space Age, High-Thermal Performance Technology that was made
popular by the re-entry tile on the space shuttle. The base substance used by
SCI is Alumino Silicate Fiber, an environmentally friendly material that is
landfill disposable. This substance is combined with amorphous binders that are
natural minerals. These SCI binders minimize smoke and offgases during the
initial firing process of a new appliance in a consumer's home.
The logs and panels can withstand temperatures of more than 2200 degrees Fahrenheit.
The ceramic material selected by SCI is based on the best tolerance levels and
provides the best strength for the weight. SCI selects the ceramic Fiber that
will result in the best product strength. When combined with the binding agents,
this allows the ceramic Fiber to create a mesh of welded varying Fiber lengths
which improves strength and impact resistance.
This area is one of the most critical at SCI. Every raw material used is
tested by the engineering department before being put into the slurry. Once the
slurry is prepared, the material's vital signs are constantly monitored before
and during production. Also, due to the amount of water used during the process,
this water is recycled and used in succeeding slurry batches. This saves and
controls the water and chemicals used in the closed-loop production system.
High Temperature, Heat Stable Colors
SCI's strong commitment to detail is apparent in the application and constant
research with color. The company uses Hi-Temp, Heat Stable Pigments that resist
color fading and burn-off. The log sets maintain color consistency during the
high and low temperature cycles. Pigments have a low thermal shock level that
prevent cracking when the material cools.
SCI goes one step further with its color process. When the base coat is
applied, a two-tone highlight is created to give it a more natural appearance.
This is due to SCI's proprietary ceramic formula.
The plant's coloring department includes several different machines that
apply colors to the product. A roll coating machine applies color to a wide area
in one pass and the spray booths allow for continuous color application as well
as the application of multiple colors on one log set.
SCI uses a spectrophotometer to measure and monitor the pigmentation being
applied to the various products. Once the color specification base line is
established, the product is analyzed for color content. If this is below
standard, SCI's quality control department will adjust the batch to ensure
consistent color.
SCI's Commitment to Quality Assurance
The company concern for Quality Assurance (QA) is evident by the amount of
key QA Test Areas found throughout the plant. These nine QA locations constantly
monitor the product as it travels from the raw material state to shipping. Also,
along the way, every employee is trained to make certain his/her work center
produces the best product. The goal of QA testing is to prevent inconsistencies
that can lead to an inferior product. Some of the critical QA areas include:
 | Color pigmentation of the slurry, wet and finished products is measured
with a spectrophotometer that evaluates color on three planes. |
| Cured Products are tested to assure that the item is properly baked. |
| QA Laboratory has a variety of precision measuring equipment including:
Durometer, Hydrometer, Viscometer, Granite Surface Alignment Table, gauges
and digital calipers. This helps to assure that the SCI products are within
the designated parameters established in the Standard Operating Customer
Procedures Manual. This manual is prepared for all SCI products made. |
| Log designs are gauged to assure that tight dimensional tolerances are
maintained. Thus, logs have a consistent dimension throughout production.
The Hearth Industry depends on this principle and our customers expect
it. |
