Decreasing Shrinkage in Metal Die-Casting

Sunday January 13, 2019

Metal casting, like all industrial methods, necessitates a fair amount of accuracy and fidelity towards the intended design. However, things are rarely as simple as executing a method of production because uncalculated variables can rear their heads and ruin a design with bumps, tiny gaps and today’s topic: shrinkage.

Designing Parts for Injection Molding: 6 Things to Consider

Thursday December 13, 2018

Injection molding is an important manufacturing process used to make car parts, packaging, toys and many other products. During the injection molding process, a molten material — often a thermoplastic — is injected into a mold cavity. When the materials cools down, it can be removed from the mold as a finished product. Using this […] Read More

Engineers Should Learn Machining Skills — Here’s Why

Tuesday November 20, 2018

Both engineers and machinists play an instrumental role in the production process. The engineer designs a product, and the machinist — while attempting to follow the engineer’s precise instructions — turns a piece of metal or other material into the intended product. In an ideal world, this should be a smooth operation: engineers are required […] Read More

10 Tips for Cutting Costs on Your CNC Machining Parts

Saturday November 3, 2018

Several things can affect the cost of CNC Machining parts, including materials, design, finishes, quantity, and turnaround time. Typically, the most important is how much time it takes to machine your parts. This can influence cost even more than the cost of materials, setup time, or finishing type. Machining time is directly affected by the […] Read More

Tuesday December 25, 2018

Construction printing has seen a lot of great initiatives in the past few years, from 3D printing drones to massive cable driven, infinite-build machines. However, taking construction to the next level isn’t solely about improving the hardware but also the input materials. It’s no secret that the construction industry can be wasteful, being one of […] Read More

Things to consider when developing medical devices

Tuesday December 4, 2018

Creating a medical device is an enticing prospect. Although competitive, the medical device market can be extremely lucrative, with innovative devices capable of making millions for their creators. Needless to say, such devices can also save lives. But designing a medical device takes a lot of effort. There are more considerations, potential pitfalls and stringent […] Read More

Improving the Machinability of Aluminum

Monday November 12, 2018

The machine-friendliness of aluminum has made it the number one metal for machining. Its material properties make it easy to mill, drill, cut and punch, while aluminum machined parts can be strong, durable and aesthetically pleasing. All in all, aluminum is the most machinable metal on the market.   Despite this, aluminum is far from […] Read More

How 3D Printing & CNC Machining Prototypes Make the Fastest Cars Faster

Thursday September 13, 2018

The Hennessey Venom GT just hit 270 MPH on a runway. The Koenigsegg One:1 thinks that’s cute. And that’s because it should be able to hit 280 MPH. Oh, and it can go around corners like mad. Welcome to the new king of speed and a fast (no pun) look at the technology used to make these cars break new […] Read More

Applications of CNC Machining in the Automotive Industry

Monday September 3, 2018

In some form or other, cars have existed since the nineteenth century. Their introduction changed civilization, giving fast personal transport to large sections of the population while creating a new workforce and introducing a new aspect of popular culture. The automotive industry now exists everywhere. Although the U.S. dominated automotive production in the early 20th […] Read More
