Casting Study: Door Brake

Automatic closing mechanisms for swing doors have to be adjustable and brake the movement of the door. The mechanism must be strong, resistant, reliable and compact enough to be housed in a casing. Pressure injected zinc alloy casings offer undeniable advantages such as: – resistance to mechanical stresses – impacts, force, pressure variations – and resistance to floor cleaning solvents and cement – consistent when mass produced – durable – watertight – accuracy of the holes bored to house the bearings.
