2. Plastic hinge - Wikipedia

   en.wikipedia.org/wiki/Plastic_hinge

   By inserting a plastic hinge at a plastic limit load into a statically determinate beam, a kinematic mechanism permitting an unbounded displacement of the system can be formed. It is known as the collapse mechanism. For each degree of static indeterminacy of the beam, an additional plastic hinge must be added to form a collapse mechanism.

3. Injection mold construction - Wikipedia

   en.wikipedia.org/wiki/Injection_mold_construction

   Injection mold construction is the process of creating molds that are used to perform injection molding operations using an injection molding machine. These are generally used to produce plastic parts using a core and a cavity. Molds are designed as two-plate or three-plate molds, depending on the type of component to be manufactured.

4. Hinge - Wikipedia

   en.wikipedia.org/wiki/Hinge

   An ornate brass door hinge A barrel hinge. A hinge is a mechanical bearing that connects two solid objects, typically allowing only a limited angle of rotation between them. Two objects connected by an ideal hinge rotate relative to each other about a fixed axis of rotation, with all other translations or rotations prevented; thus a hinge has one degree of freedom.

5. Frame and panel - Wikipedia

   en.wikipedia.org/wiki/Frame_and_panel

   The basic idea is to capture a 'floating' panel within a sturdy frame, as opposed to techniques used in making a slab solid wood cabinet door or drawer front, the door is constructed of several solid wood pieces running in a vertical or horizontal direction [1] with exposed endgrains. Usually, the panel is not glued to the frame but is left to ...

6. Rotational molding - Wikipedia

   en.wikipedia.org/wiki/Rotational_molding

   A three-motor powered (tri-power) rotational-molding or spin-casting machine. Rotational molding (BrE: moulding) involves a heated mold which is filled with a charge or shot weight of the material. It is then slowly rotated (usually around two perpendicular axes), causing the softened material to disperse and stick to the walls of the mold ...

7. Matrix molding - Wikipedia

   en.wikipedia.org/wiki/Matrix_molding

   Matrix molding or matrix transfer molding is a technique often used during molding. The person doing the assembly will first create the rigid outer shell or flask , then introduce the softer and more fluid molding material between the shell and the prototype .
