Plastic squeeze bottles for water or Gatorade are ubiquitous at sporting events around the world. Hundreds of millions of them are produced annually.
Millions of bottles need millions of push-pull caps. To produce that kind of volume, there’s really only one option: a continuous motion assembly system. Such systems can routinely produce 400 to 800 parts per minute, and some machines can produce more than 1,800 parts per minute. In contrast, rotary indexing dials or pallet-transfer systems can produce 15 to 250 assemblies per minute.
