Where We Started

Founded in 1956 by Paul Mindrum, a World War II pilot









F
ound work as a defense contractor specializing in ceramics

Originally started in his garage but progressively grew until finally
moving into our current manufacturing facility in 1974

What We
D
o

We are a Woman Owned Small Business with a proven
record of providing Flight Grade Hardware/Assemblies to
Government and Primes in the Aerospace and Defense
Marketplace.

We are a multi
-
discipline contract manufacturing company
that produces precision parts and assemblies to our
customer’s specifications.

We excel in tight
-
tolerance, complex geometry parts in
both engineered and conventional materials and have 5
-
axis machining capability.

We run prototype quantities of one to production quantities
of thousands and collaborate with our customers on part
design and manufacturability.

Additive Manufacturing

We also work with a large vendor network to deliver
Additive Manufacturing solutions to our customers:

Electron Beam Melting (EBM)


Uses an Electron Beam gun in a vacuum environment to grow part


Primarily done in Titanium 6AL
-
4V

Direct Metal Laser Sintering (DMLS)


Uses a laser in an inert gas environment to grow part


Many materials including Titanium, Stainless Steel and Aluminum

Ceramic
Stereolithography

(SLA)


Uses
a laser in an ambient environment to
grow part


Part is then fired to its final hard state


Primarily
done in
Aluminum
Oxide

Can create extremely complex, even impossible shapes to
machine conventionally
–

then tight
-
tolerance, critical
features can then be added by our shop after.

Microvalve

We recently acquired the license to be the sole
manufacturer of the
Microvalve
, a Miniaturized
Double
-
Latching Solenoid Valve that was
developed at NASA Goddard Space Flight Center.


It was developed as part of the Surface Analysis
at Mars (SAM) suite in the Mars Science
Laboratory (MSL)

within the Curiosity Rover,
which successfully arrived on Mars in August
2012.


We are currently building Flight
Microvalves

for
NASA in support of SAM

How can we help meet your requirements?

Assist in the early design process by providing insightful feedback
on manufacturability challenges and concerns.


Provide turn
-
key parts by handling material requisition, fabrication,
assembly operations and post
-
processing such as plating and
coating.


Provide one
-
stop shopping on components and assemblies from
both engineered materials and conventional materials.


Provide rapid turn
-
around of prototypes, modifications or
manufacturing of smaller production quantities, eliminating difficult
tooling requirements and long conventional lead
-
times.
