[1] The purpose of a drain is to prevent fluid (blood or other) build-up in a closed ("dead") space, [ 2 ] which may cause either disruption of the wound and the healing process or become an infected abscess, with either scenario possibly requiring a formal drainage/repair procedure (and possibly another trip to the operating room).
Squeeze casting is a casting method that combines die casting and forging. It starts with low-pressure casting, followed by the application of very high pressure as the material cools, producing a high-quality casting. [1] [2] This is often carried out using a hydraulic press as part of the casting apparatus. [3]
Plastic surgery is increasing slowly, rising 115% from 2000 to 2015. "According to the annual plastic surgery procedural statistics, there were 15.9 million surgical and minimally-invasive cosmetic procedures performed in the United States in 2015, a 2 percent increase over 2014."
Starck has publicly stated that his citrus reamer was "not meant to squeeze lemons" but "to start conversations". [10] An image of the Juicy Salif was featured on the front cover of Donald Norman's book Emotional Design. [12] The gold-plated version was described as an "ornament" because citric acid from fruit would discolor and erode the gold ...

A squeeze bottle is a type of container such as a plastic bottle for dispensing a fluid, that is powered by squeezing the container by exerting pressure with the user's hand. Its fundamental characteristic is that manual pressure applied to a resilient hollow body is harnessed to compress fluid within it and thereby expel the fluid through some ...
The pattern is specially vented so that a vacuum can be pulled through it. A heat-softened thin sheet (0.003 to 0.008 in (0.076 to 0.203 mm)) of plastic film is draped over the pattern and a vacuum is drawn (200 to 400 mmHg (27 to 53 kPa)). A special vacuum forming flask is placed over the plastic pattern and is filled with a free-flowing sand.
The person designing the mold chooses whether the mold uses a cold runner system or a hot runner system to carry the plastic and fillers from the injection unit to the cavities. A cold runner is a simple channel carved into the mold. The plastic that fills the cold runner cools as the part cools and is then ejected with the part as a sprue.
