DuraTech is a polyurethane tooling material that outlasts and
outperforms both steel and plastic tooling. It is the most wear
and impact resistant material on the market today. DuraTech provides
exceptional strength, durability and effortless mold release. It
is ideal for single and multiple cavity patterns as well as core
box construction.
DuraTech's proven resilience against abrasive foundry
sands makes it the perfect material for high volume production.
In fact, one of our six-cavity core boxes has produced over two
million sand cores without any breakdowns or repair. Can your
tooling do this?
DuraTech can be used with all high-speed cutters
and machines perfectly in all applications while maintaining superior
stability. Shavings, not dust, are produced and there are no glass
bead fillers to damage cutting tools.
DuraTech can be permanently bonded to itself or
onto any clean surface including wood and metals. This eliminates
the need to start from a solid block of material thus minimizing
product waste. We use a urethane adhesive resin and epoxy hardener
to bond DuraTech.
Applications for using DuraTech are endless. Thin
DuraTech sheets can be glued to high wear areas of existing core
boxes to extend the life of the box. Patterns can be made undersized
and then have DuraTech added for increased strength and durability.
DuraTech can also be used on high wear areas of industrial machinery.
DuraTech is available in solid form only. It is
not a type A and B material, but is machine mixed and gravity poured
at 250°F.
Boards of DuraTech are kept in stock. (31.5" x
55"=12 sq. ft.) They range from 1/8" to 2" thick. Thicker boards
are available upon request. Shorter boards are also available, however,
one side is always 31.5" and a cutting fee of $15 applies. DuraTech
can be custom ordered in boards, blocks, rods or tubings to meet
your unique specifications. Durometers range from A-60 to D-70.
Our standard is D-70 orange. Special colors are available upon request.
We recommend using a silicone spray release daily
on DuraTech patterns and core boxes.
For a quotation please call, fax or email your
dimensions.
Do not use DuraTech in environments above 200°F.
Some clients have asked if they can arrange to have DuraTech poured into their own tooling. The answer is yes! Tooling for pouring DuraTech has to be produced out of a heat and moisture resistance material and constructed for gravity pouring. The shrinkage for pouring DuraTech D-70 is 2%.
Please call Adolf for specifics on developing your own tooling.
