When a new part number is introduced into the system, the
first step is to machine up the required tooling to produce that
particular spring. |
 |
 |
Every new part number introduced also has a CNC program written for that
particular spring. |
|
The spring steel used in the manufacture of Newcom springs
is from the Australian company BHP. Newcom purchases spring steel in BHP bundles, ensuring full traceability of Newcom springs. Currently,
we manufacture springs from 10mm to 24mm diameter. |
 |
|
|
Once the spring steel has been cut to the required length,
the material is fed into our walking beam furnace. The material is
automatically ejected from the furnace when the material has reached the
required coiling temperature.
|
|
The main furnace utilises Stordy flat flame burners that
distribute heat evenly over the material.
|
 |
|
|
This photo is showing a spring being produced. Our CNC
coiling machine was designed and built with the capability of coiling springs twice the material diameter of what we currently produce. |
|
Once a spring has been formed, it is rolled into the
quenching oil. |
 |
 |
After the quenching process, springs go through the
tempering furnace. Tempering a spring is a critical process. A certain hardness must be achieved to produce a
good spring. |
|
Some springs require ends that are ground flat. Certain
companies swage the spring ends, but we prefer to grind them flat. A
spring that has been ground flat will not only sit better in the locator, it
also aesthetically looks better. |
 |
 |
Springs are then shot peened. This process 'de-stresses'
the spring and increases the working life of a spring as compared to a spring that
has been sand-blasted. It also removes scale from the spring surface for a
smooth, glossy, powder coated finish. |
|
Every spring is 100% tested. There is no batch testing of
springs in our manufacturing plant. Every spring is scragged to full
closure, (some designs even allow for a 4 tonne load to be applied) then
the load height is measured to within +/-2mm of specification. |
 |
 |
Springs are powder coated to protect the spring surface
from deterioration and for aesthetic purposes. Powder is applied to a
spring,
then baked in low temperature oven. |
|
The finished product before it receives its sticker that
has the part number and traceability information. |
 |
 |
Springs are then packaged into boxes,
or in any other packaging requirement that the customer specifies. |
|
The last step is to place the springs in
bulk shippers, ready for
freight to the customers premises. |
