Famous automakers around the world rely on the sintering process in powder metallurgy to improve their components’ performance and economic efficiency. New advances in sintering can lead to even higher overall performance for those automakers -- as well as other industries.
But the advantages of sintering are a moot point if your manufacturer can’t control the process.
Sintering furnace problems can ruin the metallurgy, shape, magnetic quality, and other properties of your component. To meet the exacting demands of automakers and other industries, many metallurgical companies have installed automated systems to continuously monitor the furnace’s most important operating parameters.
For sintering or sinter hardening -- a strength-enhancing technique only available in PM -- that means adding real-time analysis. At Horizon, our furnace’s specially designed “S.M.A.R.T. System” informs us immediately of changes in the furnace that could impact your final product.

Your powder metallurgy supplier should work hard toward reducing spills, recalls, and warranty claims related to sintered components. Horizon’s new S.M.A.R.T. System -- the work of Abbott Furnace -- emphasizes continual monitoring, defect prevention, and reduction of variation and waste in the supply chain.
The new system helps meet customer expectations, along with many standards of the auto industry and elsewhere. One example is the CQI-9 “certification” some automakers require of parts suppliers for heat treating management and continuous improvement. CQI-9 is not something powder metallurgy manufacturers get “certified” to, no third-party auditor is knocking on our factory door, and it only affects a small sector of auto parts makers. But it has been a great catalyst for a push toward continuous improvement of the sintering process.
Here’s how our advanced sintering furnace helps us collect valuable data for the customer’s peace of mind:
Controlling sintering parameters means understanding the four primary variables of sintering:
Historically, tracking furnace performance has been a manual process. With Horizon’s new continuous improvement add-ons, we can monitor the tolerances we’ve established on these three variables in real time. The technology allows the manufacturer to establish specification ranges in the controller itself.
There are electronic outputs coming from:
The most important role our new system plays is checking the chemistry of the atmosphere. In the past, your supplier’s engineers would have to wait until the component exited the furnace to see how it turned out. Now the engineers can be notified of changes immediately.
Typical powder metallurgy companies have control over these variables to some extent. But all they get when a problem arises is an audible alarm. Horizon’s setup includes an audible alarm, but we also receive continuous data so we have historical reference for the furnace’s performance.
The new furnace technology isn’t just a simple failure analysis of heat-treated steel components. It’s about capturing the furnace’s performance in good times and bad. This peek into associated product quality for any day and time means there’s no veil over transparency.
The customer gets the benefits of:
Right now this technology is a standalone system. Where metallurgists can really increase its power is to integrate it directly into manufacturing cloud software such as Plex Systems. Use of this ERP software is one of the many improvements we’re making as the powder metallurgy industry becomes one with Industry 4.0.
To receive a more satisfying return on your partnership with a powder metallurgy company, work with someone who’s committed to both continuous improvement and Industry 4.0 best practices -- like using Plex.
