To aid in controlling the thickness of molded parts and/or support the pressure loads put on sections of a mold, lands in the mold are used. Examples of lands are shown in Figure 14.2. Figure 14.4 shows the land locations used in a mold that supports the split-wedge in the mold. 

When tool steels of high hardness are used they are supplied in the soft annealed condition (hardened mold inserts for cores, cavities, other molding surfaces and gibs, wedge locks, etc are typically hardened to a...

Discussion Pepper mites are small (250 microns long) with yellowish brown, wedge-shaped bodies, crossed by a central whitish band. Red pepper mites are often seen as a swarming jostling mass, on mushroom caps orthe surface ofthe casing. These mites ace commonly associated with Peniciilium and Trichoderma molds, upon which they feed. 

Figure 86b shows a mold that can be disassembled, devised by G. Grube and H. Schlecht [Z. Elektrochem. 367 (1938)], It is made of machined steel pieces and produces oblong, coliomnar wedges of compressed powder. 

Silicone laminates are used principally in electrical applications such as printed circuit boards, transformers, and slot wedges in electric motors, particularly class H motors. Compression-molding powders based on silicone resins are available and have been used in the molding of switch parts, brush ring holders, and other electrical applications that need to withstand high temperatures. 

Dowel dau(-9)l [ME dowle akin to OHGr tubili plug, LGk typhos wedge] (14c) (dowel pin) n. A hardened steel pin, usually having a shght taper, used to maintain alignment between two or more parts of a mold or machine. 

Molds should be designed to minimize flow and weld lines. The gate should be a wedge-shaped fan or tab to minimize flow problems. Also, gates should be... 

Parts A and B are ejected from the mold and then separated from the piece. These sections are made with a taper to fit the chase or honsing. Mold sections and other loose parts are generally called wedges.
