Quick question for the sourcing floor.

In China right now, magnesium alloy is about 30% cheaper than aluminum by weight.

So why is almost every EV housing still made of aluminum?

It is not a trick question. The raw material savings disappear the moment you account for corrosion behavior, surface treatment limits, and the fact that most thermal management specs are written around aluminum conductivity. Magnesium is lighter and cheaper, but it changes every downstream process.

Still, 30% is a number worth paying attention to. Waffer Technology just put a 7,000-tonne magnesium thixomolding machine into production. The material is moving from small brackets toward structural parts.

So what is holding your team back from magnesium — corrosion, thermal, or just no demand yet? Tell us below.

Honest question for the casting floor.

When a single part fails porosity, what does it actually cost you?

Not the quote price. The real cost: the leak that reaches the customer, the line-down chargeback, the expedite freight, the engineering review, the root-cause report, the corrective action.

A reject rate of 2% sounds low until it lands on a 50,000-unit program. That is 1,000 parts — and 1,000 chances for one to slip through and reach the field.

Most shops catch porosity by sampling. A few check every part. The difference shows up not in the inspection report, but in the warranty claim rate months later.

So here is the question: in your current process, is porosity something you catch before shipping, or something your customer catches after?

Vote below and tell us what your biggest porosity headache is.

The carbon tariff on aluminum castings is not really about carbon. It is about data.

From 2028, the EU's CBAM pulls die-cast aluminum parts into its scope. If a supplier cannot show verified emissions data, the EU applies a default — around 3.3 tonnes of CO2 per tonne of aluminum, close to double the real figure for Chinese metal. No data means paying roughly EUR 145 extra per tonne.

So the supplier who wins the next EU order is not the one with the lowest carbon. It is the one with the cleanest paper trail. A verified carbon trail is now worth more than a low sticker price.

Does your current casting partner give you the carbon data, or just a certificate? Tell us below.

Here is a number that matters more than any tonnage figure this week: 0.5 percent.

That is the porosity level the new semi-solid rheocasting platforms are claiming, down from the 3 to 5 percent that conventional high-pressure die casting has always lived with.

Meanwhile, Leggera is breaking ground on thixomolding presses in Michigan, and PSW Group just launched a semi-solid casting center. The industry is quietly pivoting from bigger machines to cleaner metal.

Here is the truth nobody puts in the press release. A 9,000-ton press does not fix a micro-pore in your cooling jacket. For motor controller and PDU housings, the battle was never tonnage. It was always porosity.

At EMP Casting, every housing is 100% helium leak tested and friction stir welded. No pores, no pinholes, no exceptions.

Here is a number that made the rounds this week: 86.
As in, 86 stamped metal parts replaced by one single aluminum casting, thanks to Toyota’s new gigacasting setup. Three minutes per piece. Body assembly time cut in half. Impressive numbers.
And Toyota is far from alone. Ford is retooling Louisville around the same technology. Volvo already casts its EX60 rear underbody in one piece. The gigacasting wave is real.
But here is what the headlines skip. The die-cast parts that actually cause warranty claims and production stoppages are almost never the big structural ones. They are the smaller, higher-precision pieces: motor controller housings with thin-wall cooling jackets, PDU enclosures that must stay leak-tight at 800V, machined surfaces that cannot drift a single micron.
A 9,000-ton press does not fix porosity inside a cooling channel. It does not eliminate pinholes at a weld seam. It does not guarantee every single part passes a helium leak test.
At EMP Casting, we build motor controller and PDU housings the hard way: 100% helium leak testing on every part, friction stir welding for porosity-free seams, and one partner from mold design to final machining under IATF 16949.
Gigacasting is transforming body structures. For the housings that keep your electronics dry and cool, precision is still the real moat.

When Honda started casting its EV IPU battery cases on Bühler Carat 610 megacasting cells in Ohio, they cut 60-plus stampings down to 5 cast sections. Impressive consolidation.
But here is the detail most people miss. Those cast sections are joined using friction stir welding, not conventional fusion welding. Honda chose FSW because it creates a solid-state bond with zero pinholes and no thermal distortion in the cast aluminum.
At EMP Casting, we use the same principle for motor controller and PDU housings. FSW joints, 100% helium leak testing on every single part, and the full chain from mold design to machining under IATF 16949.
VW just ordered 16 new 9,000-ton Bühler machines. Volvo is installing GigaPresses in Slovakia. Megacasting is scaling fast. But the housings keeping your power electronics dry still come down to porosity control and weld quality.
What joining method does your casting partner use? Tell us below.

If you follow die-casting news, you have probably seen the headlines this week: BYD fired up a 9,000-ton gigapress. Bigger machines, fewer stamped parts, faster EV lines. It is an easy story to get excited about.
But here is what the headlines skip. When a Tier 2 or Tier 3 buyer needs an EV motor controller or PDU housing, tonnage is not what keeps them awake at night. Porosity in a cooling jacket does. A helium leak curve that fails at cycle 400 does. A wall that drifts out of tolerance after machining does.
For those parts, the answer is not a bigger press. It is process discipline. 100% helium leak testing on every housing, not sampling. Friction stir welding for porosity-free enclosure seams. One partner from mold design to final machining, under IATF 16949.
Gigacasting is great for body structures. For the housings that keep your electronics dry and cool, precision is the real moat.
What is the one spec your current casting partner keeps missing? Drop it below.

Had a great visit from a customer team based in Europe this week, always a good reminder of why we do what we do.
Nothing beats walking someone through the actual production floor, showing the die casting process, the machining, the 100 percent helium leak testing, in person instead of over a call. It builds a different kind of trust, and honestly it is just a good time getting to put faces to the emails.
Thanks to the team for making the trip out to see us. Looking forward to more visits like this. empcasting.com

Got some good footage of a horizontal CNC machining center running live at CHINA DIECASTING 2026 in Shanghai. Watching a multi axis setup cut across several faces in one cycle is a good reminder of how much precision goes into the finishing stage, not just the casting itself.
A lot of people focus on the die casting process and forget that machining is where final tolerances actually get locked in. Sealing surfaces, mounting holes, bore diameters, all of that depends on machining accuracy as much as it depends on the cast part itself.
Take a look at the clip below, this kind of equipment is exactly what keeps dimensional consistency tight at volume. empcasting.com

We spent a day walking the floor at CHINA DIECASTING 2026 in Shanghai, and it was a good reminder of how fast this industry moves.
Between booths showcasing new die casting cells, aluminum alloy suppliers, and process control equipment, one thing was clear, everyone is chasing the same goals, tighter tolerances, fewer defects, and lower carbon footprint per part.
It is easy to get heads down in day to day production and forget to look up at where the whole industry is heading. Shows like this help us stay sharp and stay connected with the people solving the same problems we are.
