These new manufacturing processes are good for Apple and good for the environment

Molly Anderson, Apple’s head of hardware design, said the company started from scratch when it came to the manufacturing process for new phones. MacBook Neoas a result, materials are used more efficiently.

The company also intends to adopt extremely difficult manufacturing techniques for the aluminum chassis of future iPhone and Apple Watch models…

“Apple” has already presented the environmental credentials of its latest laptop, saying that it has set a new record recycled materials.

It has 60 percent recycled content—the highest percentage of any Apple product. This includes 90 percent recycled aluminum overall and 100 percent recycled cobalt in the battery.

New MacBook Neo processing

The company also hinted at a new manufacturing process, but did not provide details at the time.

The case is manufactured using a material-efficient molding process that uses 50 percent less aluminum than traditional machining methods.

For previous MacBooks, Apple started with a rectangular piece of aluminum and machined it into shape. This resulted in a significant unused cut. For the MacBook Neo, however Anderson explained the company has been able to drastically reduce the amount of unused aluminum.

“We start with extrusion, flatten it, and then shape it with heat and pressure to get as close to the shape of the final product as possible,” Anderson said. “Then we fine-tune the machine to create a profile.” According to Anderson, this (…) cut the amount of material used in half.

Reducing material waste is good for Apple’s margins, but it’s also good for the environment. While the company certainly recycles as many scraps as possible, a more cost-effective approach is to reduce their number. Anderson added that it also reduces the amount of processing time, which likely reduces power consumption.

3D printed iPhone and Apple Watch chassis

Apple started first Using 3D printing for the titanium chassis Apple Watch Ultra 3. The company said at the time that this allowed it to use 100% recycled titanium powder and was a more efficient use of the material.

A Bloomberg The report says that the company is currently working on roads 3D printed aluminum for the chassis of both future iPhone and Apple Watch models.

3D printing aluminum is a very difficult process for a number of reasons. The high reflectivity and thermal conductivity make the material difficult to form with lasers, and extreme precision is required to avoid the risk of microscopic internal voids that can reduce the strength of the finished product.

For these reasons, it is typically only used in applications such as aerospace and automotive manufacturing, where weight savings and large material volumes justify the complexity of the manufacturing process. It would be a significant achievement for Apple to successfully mass-produce small consumer electronics devices.

Wins for Apple and the environment

Highlighting the environmental credentials of new products while saving money on their production is the biggest win for Apple’s bottom line and the environment.
