Plastics
We have both experience
and proficiency in the following manufacturing practices with regard to
plastics. Our capabilities include the ability to do
Injection Molding, Insert
Molding, Over Molding, Blow Molding as well as Extrusion. Read further
to understand the differences in each type or contact us and we will be
happy to discuss which is right for your product.
What plastic is right for me?
We will analyze
your product for the required physical and mechanical properties to choose
an accurate material for your product. Common requirements often
include high strength, temperature resistance, weather resistance, or extra
high precision.
We have experience
with regards to plastic product manufacturing in materials ranging from common
resins to engineered resins (fairly exotic). We have previously manufactured using
plastics from the families of PP, PE, PVC, ABS, AS (SAN), Acetyl, Nylon,
to name just a few. We use materials from world class manufacturers like Dupont,
LG, BASF, Sinopec, Ciba and so on or the lower end depending on what
kind of budget you have for your product and the requirements of the product. Some specialized injection
molded plastic parts may require reinforcement with glass or carbon fibers
imbedded in the resin.
Our experts in plastic coloration can choose pigments to give your product
the desired color. We custom match the color required and have a
master batch created so that all products are consistently the same color
throughout the life of the product. Often, ultraviolet inhibitors can be added to
protect the product against color fading as well as protecting for a weakening of strength
from sunlight. Click here to read more about
injection molding.
Insert Molding
Insert molding is a process which uses injection molding to join separate
parts together into a single component. Basically, a second object
which is metal, plastic or other,
is inserted into a custom-designed injection mold. After the injection
molding cycle, the 2nd piece is permanent embedded into the product.
As the 2nd piece is inserted into a mold, what you get is a
high-quality product
which is durable and always aligned perfectly.
Why use insert molding?
When not using
insert molding, the assembly/connection of discrete parts through fasteners,
connectors, soldering or adhesives is labor-intensive, costly and not as
secure. In addition to greater efficiency, insert molding offers many
other benefits.
Using a method whereby you connect 2 parts together, you will need to use a
form of connector which adds weight, will not be as durable for the
short-term or for long term. As the connector itself is plastic of the
product, you eliminate the connector, thereby reducing the cost as well as
the weight of the connector.
No matter whether we use insert molding or assemble pieces using other
methods, we combine manual
and automated techniques to ensure optimum results in all of our products.

Over Molding
Over molding is a
process that allows
for two different molds to be used to injection mold the same part in order
to improve appearance or
durability. A good example is over molding a rubber handle/grip over a
product.
It is also commonly used when a combination of inserts is too complex to be
completed by one molding process. The most common applications of over molding
are so that
the product has a more comfortable and better grip,
insulate electrical components, make parts water resistance or reduce
vibration during product use.

Rapid Prototyping
Rapid Prototyping/Model Making is often a crucial step during the product
design and development cycle.
It is very useful in checking form, function and appearance before spending
large amounts of time and money the production mold. Often, 2D and 3D
drawings and sketches are very valuable in determining dimensions and
general form, but sometimes critical ergonomic and atheistic features aren't
noticeable until you can see and feel an actual size product. We
provide high-quality,
high-precision prototypes for your consideration.
Using prototypes reduces the risk to you, allowing you to test
the market by showing off an actual sample for comments and feedback before investing in any expensive
production tooling.
