Part
Requirements for Rapid Injection Molding and Tooling |
| Part
Size |
Overall
part size cannot exceed 7.5 inches in any direction. |
| Draft
Angles |
Draft
angles are not necessary; however, any draft angle can
be included in the part design. Textured parts
require draft. |
| Undercuts |
Undercuts
are no problem. Even internal and external threads are
possible. Parts with a collapsible core design are also possible. |
| Fillet
Radii |
Fillet
radii should be included in all part designs.
Generally, a minimum of .010 radius should be used. |
| Tolerances |
Normal
part tolerances are plus or minus .005 of an inch on
all dimensions an inch or less. Dimensions over 1 inch add
.001 per inch. Tolerances can be held closer in
specific areas called out prior to the tool build. |
| Part
Weight |
Part
weight must be at least .1 gram, but not more than 210
grams (approx. 7 oz.) |
| Material |
Most
all injection grade materials can be molded; even
filled materials with glass or carbon fiber are fine.
Materials requiring a hot mold can also be molded,
however, the maximum mold temperature cannot exceed 450
Degrees F. |
| Color |
Most
materials can be colored. Generally speaking, if a
custom color is required, the delivery date will
be affected. |
| Surface
Finish |
Surface
finishes can range from a mirror finish to a textured
finish. Optical wavelength surfaces are not possible. A
satin finish is the most common and will not show
fingerprints (recommended). |
| Cavity
Life |
Cavity
life is guaranteed for 2 Million parts. Advanced
Technology backs this guarantee on all of its molds.
There are NO maintenance charges on tooling. |
| English
or Metric |
Electronic
data files for part geometry can be submitted in either
English or Metric. |
| Media
Transfer |
Unfortunately,
we do not work from part drawings except for quality
inspection purposes. You must provide a solid model part
file preferably a Solidworks .prt file or a 3D trimmed
surface .IGS file. Please call to let us help you with
your quote. |
