Sintering is a manufacturing process used in the industry to create solid objects from fine powders (metallic or ceramic). The process involves heating the material to a temperature below its melting point so that the particles bond together.
The automotive sector is one of the largest consumers of parts made with the sintering process (pulleys, gears, valves...), although it is also widely used in sectors such as aerospace, medical, or toys.
The most commonly used materials for sintering are:
AISI 314 - Alloy widely used for temperatures up to 1150 ºC. It exhibits good mechanical properties at high temperatures, as well as resistance to oxidation and carburization, provided it is not exposed to corrosive environments in the temperature range between 700º and 900º, where it is sensitive to carbide precipitation.
AISI 330 - Alloy with a 37% nickel content and 17% chromium, with the rest of the components in proportions similar to AISI 314. In most applications, this material is more resistant to surface oxidation because it forms a thin layer of Cr and Si oxides that protect the wire when hot.
Other materials can be used according to our customers' specifications.
At Campbelt, we manufacture a highly efficient metal belt for working at high temperatures. Our ER belt has straight rods, and clinched selvage. The result is a strong belt perfect for high-temperature applications such as sintering.
Choosing the best belt and the right material for your sintering process is crucial as the metal belt plays a very important role. Depending on the sintering process and materials, the specifications and requirements of the metal conveyor belt will vary.
If you have any doubts about which material or type of belt would be suitable, contact us.
