Die casting is a process that produces metal parts by forcing molten metal into reusable steel molds under high pressure. These molds also known as dies are specially designed to produce different shapes of varying complexity with a high level of accuracy and repeatability. […]
1) Incomplete Fillings: a) not enough resin to fill the mold completely b) inadequate injection stroke c) low injection rate d) low injection pressure e) resin viscosity too high f) exotic geometry […]
Living hinges are thin sections of plastic that connect two segments of a part to keep them together and allow the part to be opened and closed. Typically these are used in containers that are used in high volume applications such as toolboxes, fish tackle boxes, CD boxes etc. […]
1) Textures and Lettering can be molded on the surfaces, as an aesthetic aid or for incorporating identifying information, either for end users or factory. Texturing also helps hide surface defects such as knit lines, and other surface imperfections. The depth of texture or letters is somewhat limited, and extra draft needs to be provided [...]

Thick sections cool slower than thin sections. The thin section first solidifies, and the thick section is still not fully solidified. As the thick section cools, it shrinks and the material for the shrinkage comes only from the unsolidified areas, which are connected, to the already solidified thin section. […]
1) Drafts (or taper) in a mold, facilitates part removal from the mold. The amount of draft angle depends on the depth of the part in the mold, and its required end use function. […]
1) Sharp corners greatly increase the stress concentration. This high amount of stress concentration can often lead to failure of plastic parts. Sharp corners can come about in non-obvious places. Examples of this are a boss attached to a surface, or a strengthening rib. These corners need to be radiused just like all other corners. [...]
Die Organization for Standardization is a prerequisite for specialized production. The specialized production of the mold is to improve the quality of the die, die to shorten the manufacturing cycle, the key to lower costs. […]
1) Milk to taste Method: first clean with detergent and then to plastic cups ,soup into two key fresh milk, covered with lid, shake, so that every corner Cup contact with the milk, about 1 minute Finally Discard milk, will clean cup. […]
