Did you wonder how PARU's solar PV trackers are made?
Today, our manufacturing process will be revealed!
|PARU New Building|
Let's get started!
1. Material Warehousing & Incoming Inspection
PARU performs visual inspections on the incoming steel.
The supplier will perform functional tests prior to product delivery
and provide a certificate to PARU.
PARU will also perform a thorough functional inspection
before further processing.
|Laser cutting & Bending|
2. Laser Cutting & Bending
When the materials arrive from the suppliers,
they are laser-cut, bent, and pressed into the desired shapes.
With visual inspections, dimensional measurements are performed by hand
with calibrated tools and compared with original drawing.
3. Manual & Robot welding
PARU has a welding jig set to make sure that pieces are welded
in the correct place and alignment.
The jig set includes two jigs:
for the top and the bottom post.
4. Process Inspection
Another visual inspection and a magnetic particle inspection
will be performed after welding.
PARU's inspection sampling rate is 1%.
Any defects found during the inspection will be sent back.
The welded parts will be sent out for galvanization at third parties.
The galvanization contractor performs 100% inspections on appearance
and on bending/deformation test.
And he or she provides certificates of compliance with the delivered product.
|Critical Parts Assembly|
6. Critical Parts Assembly & Function Test
Slew drive, actuator, sensor, controller
These critical parts are assembled in this process.
Once they are done, they must pass a function test.
100% of the critical parts assemblies are put through
the functional test and the results are recorded in a log.
7. Packing & Shipment
The last procedure of the manufacturing is packing.
After packing, the products will be delivered directly to the project sites.
For Alamo Project in the US,
PARU delivered the products from Kwangyang port to Long Beach port in LA.
