Ordinary door handles are widely criticized for their simplicity, but in general, there are many other problems in society that are never really mentioned in daily conversation. But don’t be afraid, for Matthew created something more special: a door handle in the shape of his own outstretched hand.
This building is inspired by a similar door handle in the wndr Museum in Chicago. You can also create it yourself. This is achieved through a multi-stage mold making process. [Matthew] the first step is to make a flexible hand model with the perfect sodium alginate material.
Once solidified, [Matthew’s] hand was removed and the mold was filled with wax. The wax replica of Matthew’s hand was then used to make a plaster model for casting metal. Vents are added at the end of each fingertip in the mold to allow molten metal to effectively fill the entire cavity.
Once the mold is firm and dry, the wax melts and is ready for casting. The cast metal is melted in a propane furnace and the mold is filled with a simple gravity casting method. [Matthew] finally made two hands, one aluminum and the other copper. Clean with a grinder and steel wheel. He has a copy of Matthew’s hand in his hand!
The finished product installed on the door handle looks great. We are sure that we can shake hands with your heavy metal self every time we open the door, which is very satisfactory. It is worth noting that the same technology can also be used for 3D printing! If you have completed your great family actor project, be sure to write to us. Play the video after the break.
