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/Side Actions |
Yes. Undercuts
and side actions are no problem. Even internal and external threads are
possible. Parts with a collapsible core design are also possible. |
| Insert Molding |
Yes. We regularly do insert molding. |
| Overmolding |
Yes. We regularly do projects with overmolded soft grips over rigid substrates. |
| 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. |
| 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 +/- .005 of an inch on
all dimensions an inch or less. Dimensions over 1 inch add
.001 per inch. Tolerances for critical dimensions can be held closer in
specific areas called out prior to the tool build. These can be held as tight as +/- .001 or .002 depending on part design and material. |
| 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. Typical rigid materials include ABS, Polycarbonate, PC/ABS, Acetal, Nylon, PPS, Polypropylene, Polyethelene, PEI, and Polyester. Typical flexable materials include TPUs, TPEs and soft PVCs.
Materials requiring a hot mold can also be molded (i.e. Ultem, PEEK, etc.)
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). |
| Secondary Operations |
We offer a wide variety of secondary operations for our customers, including post-molding machining operations, pad printing, ultrasonic welding, cosmetic paint decorations, surface treatment for shielding, light assembly, custom packaging and more. |
| English
or Metric |
Electronic
data files for part geometry can be submitted in either
English or Metric. |
| Media
Transfer |
3D file required. 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.
We receive many requests to quote to 2D drawings, and although we would love to accomodate each request, due to the volume received and the nature of our process, unfortunately we must decline.
We only utilize part drawings for quality
inspection purposes. |
