Casting | Art techniques materials
Casting is a manufacturing process in which a liquid material is usually poured into a mold, which contains a hollow cavity of the desired shape, and then allowed to solidify. The solidified part is also known as a casting, which is ejected or broken out of the mold to complete the process. Casting materials are usually metals or various time setting materials that cure after mixing two or more components together; examples are epoxy, concrete, plaster and clay. Casting is most often used for making complex shapes that would be otherwise difficult or uneconomical to make by other methods.Casting is a 7000-year-old process. The oldest surviving casting is a copper frog from 3200 BC,More info:wiki

#8 What is Die Casting,More info:abdiecasting
Many modern products such as metal enclosures, faucet parts, pistons, knobs, filter housings and microwave components are created with die casting processes. While most die casting is used for high volume production with the cost of creating dies for individual parts being relatively high, A&B Die Casting is one of the few facilities that has reinvented this process to provide cost-effective solutions for small to medium production runs.
Die castings are produced by injecting molten alloys into custom-made reusable steel cavities known as dies. Most dies are made with hardened tool steel that have been machined into net or near net shape die cast parts. The alloy solidifies within the die to produce the desired component allowing for superior accuracy and repeatability. Some of the most popular die cast alloys are Aluminum, Zinc, Magnesium, Brass, and Copper. The strength of these materials creates a finished product with the rigidity and feel of metal and the high performance of expensive plastic and advanced composites. Fine details such as textured surfaces, names or logos are easily produced without the need of costly post-processing.

#6 SLA 3D Printed Investment Casting Patterns,More info:forerunner3d
The investment casting process has been around in one form or another for thousands of years. In the early 1990’s its was revolutionized when the first 3D Printing process was adapted for it. That process was SLA 3D printed investment casting patterns. The following article will explain how traditional “lost wax” investment casting works as well as how a process built on SLA 3D Printed investment casting patterns works and why it is the best choice for either low volume or prototype casting production.
#5 Half Tonne Cast Iron Gutters,More info:ballantinecastings
We have been involved in heritage contracts throughout the world for over 150 years but a recent contract is undoubtedly one of the most impressive. Working on one of the UK’s most famous buildings Ballantine Castings was awarded the contract for the replacement of over 11.5 tonnes of 3 metre long, cast iron gutters.
We’ve made thousands of gutters over the years but none quite as large as these. All ironwork had to be withing a +/- 1 mm tolerance on every dimension cast in Grade 250 iron. Each cast iron gutter weighs c. 560 kilograms with a 16 mm wall section. We made all of the patterns in house in our traditional pattern shop. Pattern production was carried out within 1 week of receiving the order – we pride ourselves on quick turnarounds and high quality castings. By making everything in house we’re able to prioritise jobs to suit our customers’ requirements.
#4 Art Casting with Bronze and Brass,More info:belmontmetals
Creating art using the casting process dates back thousands of years as the oldest surviving piece of cast art dates back to 3200 BC. Yet artists today still enjoy creating a range of decorations, statues, figurines, jewelry and other artistic pieces using this process. The procedure involves using molten metals that are poured into a mold. Then the metal cools, it takes the shape of whatever the mold is as the metal is removed and often polished to remove any imperfections and to enhance its finished beauty.
Brass and bronze are two common alloys that are very popular when it comes to casting decorations whether for hobbies or as a profession. There are a wide variety of brass and bronze alloys available from Belmont Metals that you can use in jewelry and art casting.
