Customers
desiring to use porcelain or refractory ceramics in their
work should send blue-prints, sketches, or pictures of
product or design to Universal Clay Products Staff for
assistance. We can take a concept
from Research & Development to market testing to
full manufacturing!!
Allow
us to provide you the technical ceramic support through
all phases of product development with our in-house:
-
Drafting
and design capabilities (CAD)
-
Tool
and die shop (building new to maintenance)
-

There are
no established "rules" for designing parts made
of electrical porcelain or refractory ceramics. However,
costs can be kept to a minimum, rejects reduced and more
satisfactory parts produced when certain basic design practices
are observed.
-
General: Ceramic
parts should be designed with a configuration as simple
and regular as possible. Avoid large variations in
thickness of cross section and "deep draws." A
radius or chamfer on the edges and corners reduces
chipping and enhances appearance.
-
Tolerances: Care
should be taken that tolerances specified are necessary
for functional performance, and are not merely a carryover
of metal fabricating practices where closer tolerances
are much more easily obtained. This applies to thickness
of the parts, as well as to location and diameter of
holes, and the size of the piece.
Standard
commercial tolerances are +/-0.015" per inch on dimensions
of one or more, but not less than +/- 0.015", except
that consideration should be given to dimensions affected
by the pressing operation.
-
Simplicity: Variation
of level or thickness creates differences in density,
increases warpage and the possibility of cracking.
-
Holes
and Counterbores: Vertical holes should not be
less than .060" diameter -- horizontal holes
.125" diameter. The material thickness between
holes and counterbores should be as thick as possible.
Allow for draft in counterbores and blind holes.
-
Glaze: On
glazed pieces, an unglazed surface must be provided
for firing purposes. This unglazed surface should be
so located that the piece will not tip over during
the firing process.
