Teardown of an impulse sealer.

Описание к видео Teardown of an impulse sealer.

An impulse sealer is a device that heat-seals plastic bags closed. You place the bag across a heater zone and sandwich it down with a spring loaded handle. When pressed down, a heating element is energised for a short adjustable time and when the handle is released the bag is sealed shut by virtue of the heat fusing the two layers of plastic together.

These things used to cost hundreds of pounds, but can now be bought for about 20 pounds on ebay.

So I bought one.

Then I took it to bits.
