Lee, Allen. "Baseball Rubber Cork Core." Alibaba.com. Hong Kong Limited, n.d. Web. 01 May 2013. (Rawlings) Cork pill Cowhide leather 3,4 ply wool yarn/poly yarn Cork & rubber core, or cork pill, is from Fujian, China
- Costs $0.5 per piece

- Cork is 1 inch in diameter
- 2 shells of black rubber(4mm thick each) are molded to cork
- Thin layer of red rubber is molded
- It should be about 24.8 grams It takes 13- 14 minutes for a worker to hand-sew Cowhide leather is from Zhejiang, China
- Costs $15 per square meter



- Removing the skin from dead cow
- Salted, tanned, dried and painted
- Compressed to 1-2 mm
- Cut into same size 350 sewers produce 8000-10000 balls a day 3/4 ply wool yarn is from Inner Mongolia, China- $10 per kg
Poly yarn is from Zhejiang, China- $2.2 per kilogram



- Removing a sheep's fleece
- Scouring with hot water and detergent
- Carding(straightening the fibers and removing all unwanted materials)
- Roving
- Spinning and twisting into yarn 1. The workers put the cork pills in container and pour latex in it.
2. The container evenly distributes the glue on the pills.
3. 4 ply grey wool yarn is winded around the core by winding machine.
4. 3 ply white wool yarn is winded on it again.
5. 3 ply grey wool yarn is winded on it again.
6. Poly yarn is winded on final layer for smooth surface.
7. The workers put the balls in container and pour latex in it.
8. They cut the cowhide leathers into 8 like shape using hydraulic compressor.
9. Skilled workers stitch 2 pieces of leather together
10. Pressing machine makes the surface smoother.
11. Trademark, logo and commissioner signature is stamped on balls In MLB(Major League Baseball), each team orders 113,850 balls per year because about 60 to 70 balls are used in a match. Product delivery Baseballs are used for playing baseball.games Energy used Used balls are used for practicing or sold for cheaper price.

Many MLB teams use a "ball recycler" or "ball renewing" machine. There are few manufacturers of these machines around, but at $1,500 per unit.

They do this by loading a small drum with 20 to 30 baseballs and a dry cleaning agent inside, then rotating the drum similar to a rock polishing machine. It's quite effective, and it looks like the baseballs are renewed to about 90 to 95% of their original condition. Ships, trucks, Airplanes Energy used Residues and pollutants Human energy and
