2. INTRODUCTION
66% of the football balls manufactured are of FIFA PRO quality , so in this
presentation we’ll be looking at its manufacturing process.

3. Step 1: Dimensions and Material
• Dimensions:
1. sphere with a circumference of 68–70 cm (or 27–28 inches)
2. weight of 410–450 g (or 14–16 ounces)
3. inflated to a pressure of 60–110 kPa (or 8.5–15.6 psi)
• Outer material- Polyurethane panels (PU)
• Inner bladder material- Latex bladder

4. Step 2 : Standards For a
FIFA Inspected ball
1. The difference between the highest and lowest diameter must be not more
than 2%.
2. At 20 °C, a FIFA Inspected ball must rebound to a height between 125 cm
and 155 cm.
3. The ball must not absorb water more than 15% of its weight.
4. It must weigh between 410 and 450 g.

6. Step 3: Virtual Representation
• 3D CAD Modelling of the ball
• CAD Model in the Analysis Software for instance on ANSYS
• Seam length and number of panels has to be decided, it is inversely
proportional to drag force experienced.

7. Step 4: Making of
Prototype
• The PU panels are cut out in sets of equal halves of a
ball.
• For instance if we are making a ball of 32 panels which
includes 1 panel with company name and other with
specifications.
• Then 30 panels are divided into 2 hemispheres of 15
panels each.
• Further the two halves are thermally bonded using a
compressor machine, keeping in between the two halves
the latex bladder.

8. Step 5: Testing of Prototype
• Weather test-
i. The ball is subjected to water and pressed in a water container using a hydraulic
press, the ball should not absorb water more than 15% of its weight.
ii. The balls are baked at 40^degree Centigrade to account for heat variations as well
• Shot test- The ball is fired 2,000 times against a steel plate at 50 kilometers per hour.
The seams and air valves must remain undamaged and only minimal loss of
pressure and changes in roundness and circumference are permitted.
• This test ensures the ball’s shape, pressure and circumference remain constant for
the duration of a match

9. Step 6: Feedback of Prototype.
• The prototype produced is used for of customer evaluation.
• The ball manufactured will be given to near by clubs, academies and players
for feedback.
• After receiving the feedback the changes will be made accordingly, but only
if they adhere to the standards set and are economical.

10. Step 7: Production
• Once the changes as
suggested according to the
feedback is made,
production on large scale
according to the demand is
initiated.
• The cost is estimated.

Fun fact-
7 out of 10 footballs in the world are manufactured in Pakistan.
