Titanium


Titanium is 30% stronger than steel, but is nearly 50% lighter. Titanium is 60% heavier than aluminum, but twice as strong. Titanium has excellent strength retention to 1,000 degrees Fahrenheit. Titanium is alloyed with aluminum, manganese, iron, molybdenum and other metals to increase strength, to withstand high temperatures, and to lighten the resultant alloy. Titanium’s high corrosion resistance is also a valuable characteristic; as when exposed to the atmosphere, titanium forms a tight, tenacious oxide film that resists many corrosive […]

How to Stop Flash in Injection Molding?


Troubleshooting flash is complicated, and often there is a lot of tail-chasing on the shop floor in trying to get a solution. This approach should lead you to the solution via a data-driven procedure. Testing the parting line, using pressure-indicating paper: The image on the left is flash-free. The part on the right side is flashed; note the location of flash where the paper is mostly white at the top and bottom. The white color indicates the parting-line touch force […]

Progressive Die Stamping


Progressive die presses stamp metal using a forming method that can encompass bending, cutting, punching and several other ways of modifying coil sheet steel. The automatic feeding system pushes a strip of metal (as it unrolls from a coil) through all of the stations of a progressive stamping die. Each station performs one or more operations until a finished part is made. The final station is a cutoff operation, which separates the finished part from the carrying web. The carrying […]

Plastic Parts Design


Designing plastic parts is a little different from designing metal parts. There are many things that must be carefully considered and planned for. Plastic parts can be made in many ways: injection molding, thermoforming, extrusion, blow molding, even casting. For the sake of brevity, this article will focus on one type: injection molding. If you’ve ever built a plastic model kit, you’ve seen and know at least something about injection molding. It is a process where heated (molten) plastic is […]

Defects in Die Casting Design


Die casting is a manufacturing process that involves production of geometrically complex parts using molten metal and reusable die casts. A simple and highly cost-effective process, die casting has been one of the most important reasons for the industrial revolution. In this manufacturing process, a die casting design is first created based on the size, shape and function of the final produced part. After the design is created, the non-ferrous metal perfect for the procedure will be chosen. The properties of the […]

Following DFM Guidelines for Working with Sheet Metal


Engineers can turn out sheet-metal designs that are both highly functional and easy to make by following Design for Manufacturing (DFM) principles. Engineers designing sheet-metal enclosures and assemblies often end up redesigning them so they can be manufactured. In fact, research suggests that manufacturers spend 30% to 50% of their time fixing errors and almost 24% of those errors are related to manufacturability. The reason behind these preventable engineering errors is usually the wide gap between how sheet-metal parts are […]

What is Metal Injection Molding?


What is Metal Injection Molding? Metal Injection Molding, also called MIM, is a low cost, high volume manufacturing process that produces custom metal parts near to net shape. It combines the way injection molded plastics are formed with powdered metal sintering to create metal or ceramic parts which are stronger, denser and more capable of complex geometric shapes than most forged or die cast metal parts. Metal Injection Molding, also called MIM, is a low cost, high volume manufacturing process […]

Apple’s new MacBooks adopt metal injection molding (MIM) hinges


Apple is preparing to launch new ultra-thin MacBooks in the second half of 2016 that adopt metal injection molding (MIM) hinges. Industry sources are saying that the new MacBooks will adopt MIM hinges: To achieve an ultra-thin design, Apple’s new MacBooks adopt metal injection molding-made (MIM) hinges. Amphenol is also a hinge supplier of Microsoft for its Surface Pro because of its special designed hinge. While Desay and Sunwoda Electronics have submitted battery samples for testing they have yet to […]

The world’s thinnest metal fan for laptop utilizing Metal Injection Molding (MIM) process


The small size of laptop brings new challenges to heatsink. Surprisingly, engineers have built a complete set of cooling modules in such a thin and light YOGA 3 PRO laptop: the industry’s first integrally molded cooling fan utilizing Metal Injection Molding (MIM) process, which is also the thinnest metal fan in the world. The entire fan thickness is only 3.5mm, and the blade thickness is only 0.15mm, which is equivalent to the thickness of one razor blade. Compared with ordinary […]
