Rakar Inc.
-

Since 1951!

When he moved to Los Angeles 60 years ago, Ray LaPorte had no intention of becoming one of
the leading molders of electrical connector insulators for the military.
All La Porte really had in
mind when he moved his family west from Rhode Island back in 1951 was to be his own boss.
Thus, with a $22,000 machinery investment, he set up shop with partner Karl Bischoff, whom
he had met while working as a machinist at a jew
elry manufacturer in Providence
.

The fledging company’s first job was to produce a potentiometer transfer mold for the
electronics industry for Gaylord Plastics, Inc. a local firm located next door to the 400 sq. ft.
Rakar Office. “We didn’t have any jobs,

so they didn’t have to wait for us.”

Back in the early days Rakar would take on just about any assignment & there were some
bizarre ones including a molding machine for a cup & vacuum pump device to enlarge women’s
breast tissue. Eventually, however, word

of Rakar’s reputation spread and partners Ray & Karl
were able to be more selective over the clients and molding projects they took on.

Molding Services

Injection Molding:

A manufacturing process for producing parts from both
thermoplastic and thermosett
ing plastic materials.
Material is fed into a heated barrel, mixed & forced into a
mold cavity where it cools and hardens to the
configuration of the mold cavity. Injection molding is
widely used for manufacturing a variety of parts, from the smallest comp
onent like small Lego
accessories, to entire body panels of cars.

Injection molding is used to create many things such as wire spools, packaging, electrical
connectors, bottle caps, pocket combs, and most other plastic products available today.
Injection m
olding is the most common method of manufacturing parts. It is ideal for producing
high volumes of the same object.

Compression Molding

A method of molding in which the molding material,
generally preheated, is first placed in an open, heated mold
cavity.

The mold is closed with a top force; pressure is
applied to push the material into contact with all mold
areas, while heat and pressure are maintained until the
molding material has cured. The process employs
thermosetting resins in a partially cured stag
e, either in
the form of granules, putty
-
like sheets/logs, or preforms.

Compression molding is a high
-
volume, high
-
pressure method suitable for molding complex,
high
-
strength fiberglass reinforcements. The advantage of compression molding is its ability to

mold large, fairly intricate parts. Also, it is one of the lowest cost molding methods compared
with other methods such as transfer molding and injection molding; moreover it wastes
relatively little material, giving it an advantage when working with expe
nsive compounds.
However, compression molding often provides difficulty in controlling flashing & it is not
suitable for some types of parts.

Materials that are typically manufactured through compression molding include: Polyester
fiberglass resin systems
(SMC/BMC), DAP (short and long glass
-
filled), Epoxy (short & long
glass
-
filled), & many grades of Phenolic.

Transfer Molding

Transfer molding, like compression molding, is a process
where the amount of molding material (thermoset plastic)
is measured and
inserted before the molding takes place.
The molding material is preheated & loaded into a
chamber known as the pot. A plunger is then used to force
the material from the pot through channels known as a
sprue and runner system into the mold cavities.

The m
old remains closed as the material is inserted and is
opened to release the part from the sprue and runner. The
mold walls are heated to a temperature above the melting
point of the mold material; this allows a faster flow of
material through the cavities.

The molds in both
compression & transfer molding remain closed until the
curing reaction within the material is complete. Ejector pins are usually incorporated into the
design of the molding tool and are used to push the part from the mold once it has har
dened.
These types of molding are ideal for high production runs as they have short production cycles.

Transfer molding, unlike compression molding uses a closed mold, so smaller tolerances and
more intricate parts can be achieved. The fixed cost of the t
ooling in transfer molding is greater
than in compression molding and as both methods produce waste material, whether it be flash
or the material remaining in the sprue & runners, transfer molding is the more expensive
process.

Thermoplastics & Thermoset M
aterials

Rakar has the knowledge & capability to mold many types of
thermoplastic materials. We typically use engineering grade
resins ranging from Nylon & Polyester to high performance
resins such as PEEK & LCP. Having produced small, medium &

large production runs of thousands of different products,
Rakar can meet your specific injection molding requirements
from simple to complex sizes, shapes & tolerance.
Thermoplastic Resins having specific properties are compounded with additives such as
r
einforcements (glass or carbon), U.V. inhibitors, flame retardants, conductive elements,
lubricants or toughness agents, to attain desired properties. Some thermoplastic property
benefits include:


Resins are available in a wide variety of material & color

options.


Low Cost alternative to molding large quantities of steel & stainless steel.

Capabilities

Insert molding

is a valuable, yet comprehensive
process that

should only be trusted to a quality molding company.

This
meticulous, custom molding process has many variables to
consider.

One question moldersare often addressing is how to
keep inserts
, which

may need a specific orientation, from spinning
or moving as the material is injected into the mold.

Our team here
at Rakar has tackled & achieved success over all Insert Molding
issues we have faced for the past 60 years.

The Quality process starts upon d
elivery of the inserts to our receiving inspecting department.
Once the parts are inspected and approved, they are released for use in production. From there,
we have four additional inspection processes. After the initial run of parts, they are sent to ou
r
quality control department for full dimensional & visual approval. If the part is to specification,
then they are sent back with approval to continue running the parts.

In 1954, Rakar began making molding machines for Reynolds & soon after were approached by
Sandia to make transfer mo
lds directly as well as products with the newly developed resin,
diallyl phthalate. Soon, Rakar found itself in the middle of the atomic age, making custom molds
for such firms as Bendix Corp, Amphenol Aerospace (formerly Matrix Science Corp), Cooper
Inter
connect (formerly G&H Technology), General Dynamics Corp, and Lockheed Martin. Rakar
become intimately involved in the space program, making connector insulators for the early
capsules.

By 1985, Ray LaPorte had decided to retire and sell the business to
his son
-
in
-
law, Walter
Pittman who had been working with the company for over 20 years. Walter started as the
production manager & moved his was up the company ladder till he was elected President in
1983. Ray’s other two son
-
in
-
laws also worked at Rakar a
s the company’s Vice President &
Operation Manager. In 1986 Walter & the new Rakar management team decided to move the
company & it’s over 100 employees to a new 30,000 sq. ft. facility in Oxnard, California, where
they still remain housed today!

Rakar con
tinues as a family owned & operated business with Walter’s son Daniel Pittman,
functioning as the companies Vice President & Operation Manager. Daniel has been at Rakar
since 1994. In the past 16 years, Daniel has worked in every department of the company.

While
working full
-
time, Daniel completed his MBA in 2006.

Rakar maintains their roots as an insulator specialist however; the company is branching out
with new proprietary products currently under development!
