What is ‘machinability’ and how is it measured? featured image
Saturday January 22, 2022

The manufacturing process of machining is a versatile and effective means of cutting metal and plastic. It can create very fine details with tight tolerances, and it is highly cost-effective for making prototypes and small batches of parts. However, machining doesn’t work equally well for all materials. Because the process uses a powerful rotating cutting […]

Sinker EDM vs wire EDM: Main differences and applications featured image
Friday January 14, 2022

Electrical discharge machining (EDM) is a non-conventional subtractive manufacturing process that excels at cutting through very hard materials. Unlike ordinary machining, EDM can cut through metals without making contact. It does this by creating an electrical spark that erodes material from the metal workpiece. EDM isn’t suitable for all applications, but it is an essential […]

3D printing composite materials: An introductory guide featured image
Tuesday December 28, 2021

Additive manufacturing can be used with a wide range of materials, from high-performance thermoplastics like PEEK to aerospace-ready metals like titanium. Sometimes, however, engineers want to combine the properties of two different materials, and one of the best ways to do this is by using composites. Used in processes like FDM and SLS (as well […]

Vertical milling & horizontal milling explained featured image
Tuesday December 14, 2021

Milling is a machining process in which rotary cutters remove material from a workpiece. It is one of the most important forms of machining, along with turning. Milling can be carried out manually, but these days CNC mills — controlled by computer instructions — are prominent. Importantly, CNC mills can be oriented in two ways: […]

Die casting materials & when to use them featured image
Wednesday December 8, 2021

Die casting is a highly accurate and efficient metal manufacturing process for industrial, commercial, and consumer goods. With tooling that lasts a very long time, die casting is suitable for the manufacturing of complex metal parts, offering great value when it comes to mass production. Several metals can make suitable die casting materials. These are […]

12 plastic fabrication methods & when they are used featured image
Friday November 26, 2021

Plastic fabrication is essential to most industries. From polystyrene food packaging to industrial components made from engineering-grade PEEK, plastic fabrication contributes hugely to life as we know it. Without the ability to make plastic parts, we would need to develop radically new systems of production. But plastic fabrication comprises many different methods. Injection molding, plastic […]

Aerospace CNC machining: Lightweight titanium parts and more featured image
Tuesday November 9, 2021

The global aerospace industry is a hotbed of design and manufacturing innovation, with millions and millions of complex metal parts produced yearly. An important tool at the aerospace industry’s disposal is CNC machining. Aerospace machining leads to advanced aircraft parts made from lightweight metals like titanium and aluminum, while machining is also a valuable prototyping […]

Sheet metal bending featured image
Wednesday September 22, 2021

Bending — sometimes called flanging or press braking — is one of the most important and widely used techniques in sheet metal fabrication.  Sheet metal bending allows manufacturers to turn a straight piece of sheet metal into an angled component, and this can be much more cost-effective than welding or affixing two separate pieces together.
