In the potting process, an electronic assembly is placed inside a mold (the "pot" [3]) which is then filled with an insulating liquid compound that hardens, permanently protecting the assembly. The mold may be part of the finished article and may provide shielding or heat dissipating functions in addition to acting as a mold.
A mold or mould is a hollowed-out block that is filled with a liquid or pliable material such as plastic, glass, metal, or ceramic raw material. [2] The liquid hardens or sets inside the mold, adopting its shape. A mold is a counterpart to a cast. The very common bi-valve molding process uses two molds, one for each half of the object.
Injection moulding (U.S. spelling: injection molding) is a manufacturing process for producing parts by injecting molten material into a mould, or mold. Injection moulding can be performed with a host of materials mainly including metals (for which the process is called die-casting ), glasses , elastomers , confections , and most commonly ...
The process of manufacturing molds is often highly automated. Although many of the machining processes involved in mold making use computer-controlled equipment for the manufacturing of molds (particularly plastic and rubber injection and transfer), moldmaking remains a highly skilled trade, requiring expertise in manual machining, CNC ...
Thermoforming is a manufacturing process where a plastic sheet is heated to a pliable forming temperature, and stamped to a specific shape in a 2-part mold. Or a vacuum can be used to pull the plastic sheet onto the mold in a simplified process known as vacuum forming. The excess material is trimmed off and recycled.
Blow molding (or moulding) is a manufacturing process for forming hollow plastic parts. It is also used for forming glass bottles or other hollow shapes. In general, there are three main types of blow molding: extrusion blow molding, injection blow molding, and injection stretch blow molding.
The mold was made of electroformed nickel-copper and the plastic was a liquid polyvinyl chloride (PVC) plastisol. The cooling method consisted of placing the mold into cold water. This process of rotational molding led to the creation of other plastic toys.
Low pressure molding (LPM) with polyamide and polyolefin (hot-melt) materials is a process typically used to encapsulate and environmentally protect electronic components (such as circuit boards). The purpose is to protect electronics against moisture, dust dirt and vibration.
