2. Flash (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Flash_(manufacturing)

   Flash, also known as flashing, is excess material attached to a molded, forged, or cast product, which must usually be removed. This is typically caused by leakage of the material between the two surfaces of a mold (beginning along the parting line [1]) or between the base material and the mold in the case of overmolding.

3. Threaded insert - Wikipedia

   en.wikipedia.org/wiki/Threaded_insert

   TIME-SERT insert. A threaded insert, also known as a threaded bushing, is a fastener element that is inserted into an object to add a threaded hole. [1] They may be used to repair a stripped threaded hole, provide a durable threaded hole in a soft material, place a thread on a material too thin to accept it, mold or cast threads into a work piece thereby eliminating a machining operation, or ...

4. Threading (manufacturing) - Wikipedia

   en.wikipedia.org/wiki/Threading_(manufacturing)

   In manufacturing, threading is the process of creating a screw thread.More screw threads are produced each year than any other machine element. [1] There are many methods of generating threads, including subtractive methods (many kinds of thread cutting and grinding, as detailed below); deformative or transformative methods (rolling and forming; molding and casting); additive methods (such as ...

5. Mold control and prevention (library and archive) - Wikipedia

   en.wikipedia.org/wiki/Mold_control_and...

   Mold leaves a visual indication of its presence. Though mold can be any color, gray and black spots coupled with a musty odor can indicate the presence of mold. [20] [better source needed] Books with these indicators can be isolated and treatment steps can be implemented. Books in the surrounding area can be monitored in case of further ...

6. Permanent mold casting - Wikipedia

   en.wikipedia.org/wiki/Permanent_mold_casting

   The mold life is dependent on four factors: the mold material, the pouring temperature, the mold temperature, and the mold configuration. Molds made from gray cast iron can be more economical to produce but have short mold lives. On the other hand, molds made from H13 tool steel may have a mold life several times greater.

7. Self-tapping screw - Wikipedia

   en.wikipedia.org/wiki/Self-tapping_screw

   A self-tapping screw is a screw that can tap its own hole as it is driven into the material. More narrowly, self-tapping is used only to describe a specific type of thread-cutting screw intended to produce a thread in relatively soft material or sheet materials, excluding wood screws .
