Shower door hinges are typically made using a process called die casting. This involves injecting molten metal, such as aluminum or zinc, into a precision machined mold, also known as a die. The metal is allowed to cool and solidify within the mold, taking on the shape of the dice. 

The hinge is removed from the mold and may undergo additional finishing processes such as polishing or plating. Other fabrication methods include stamping, which uses a punch press to form the hinge out of sheet metal, and welding, which joins pieces of metal together to form the hinge.

Some common causes of leaks include

• Improper sealing: The door must be adequately sealed against the shower wall or tub to prevent water from leaking. If the seal becomes worn or damaged, water can leak through.

• Loose hinges: Over time, the hinges that hold the door in place can become loose, which prevents the door from closing and allow water to leak out.

• Poorly designed door: Some shower doors may need to be appropriately designed, making them more prone to leaking.

• Improper maintenance: The buildup of soap scum and mineral deposits in the shower track can cause the shower door not to close correctly and allow water to leak out.

Regular maintenance and cleaning can help prevent leaks. If you notice any signs of a leak, it's best to address it as soon as possible to avoid further damage.

Steps you can take to adjust a frameless shower door hinge

Locate the adjustment screws on the hinge. These are typically located on the hinge side that attaches to the door.

Note that, depending on the brand and model of your shower door, the adjustment screws may be located in a different location or there may be different mechanisms for adjusting the hinge. It's a good idea to consult the manufacturer's instructions or a professional if you have any doubts about changing it.

Difference between hinge and pivot shower doors

Hinged and pivot shower doors are both types, but they differ in how they are mounted and operated.

A hinged shower door is mounted to a fixed frame using hinges. The door swings open and closed like a traditional door, with the hinges on one side of the door and the handle on the other. 

Hinged shower doors are a good option for larger shower spaces as they do not take up any extra space when opened.

 The door swings open and closed around this pivot point, which can be found on the left or right side of the door. 

Pivot shower doors are a good option for smaller spaces as they do not require extra room to swing open.

In general, pivot shower doors are considered more versatile in installation and space-saving, but they may require more maintenance than hinged doors. Both types of doors have pros and cons; the choice of which is better for you will depend on your specific needs and preferences.
