Application
Vacuum pumps for sintering and debinding
In sintering, pressed powder parts are heated below the melting point and compacted – this is how Leybold describes it. Before that, the binder has to come out of the green part: according to Pfeiffer Vacuum, the vacuum extracts the binder and prevents oxidation; Edwards sums up both as removing the binder and compacting. Below you can see how the application works, what vacuum the manufacturers name and which of their series are intended for it – 187 models from 4 manufacturers.

In short
Sintering and debinding: the key facts
- CompactingLeybold: powder parts are compacted below the melting point; DRYVAC with RUVAC WH/WSU and SCREWLINE are named.
- DebindingPfeiffer Vacuum: the vacuum extracts the binder and prevents oxidation. Edwards names EXS for debinding and sintering – removing the binder, compacting.
- About 10⁻⁴ hPaFor sintering, Pfeiffer Vacuum names about 10⁻⁴ hPa.
- Series namedBusch names COBRA, PANDA/PUMA and R5 (18 products in the product finder), Pfeiffer Vacuum DuoVane, HiLobe and UnoLine Plus (BA 501).
Operating principle
How it works: Sintering and debinding
The drawing shows the basic principle in section. The systems and pumps of the individual manufacturers differ in detail.
- DebindingThe furnace is evacuated and slowly heated. The binder leaves the green part and, according to Pfeiffer Vacuum, is extracted by the vacuum; Edwards names the removal of the binder as the first step.
- SinteringAt a higher temperature, the powder parts compact below the melting point (Leybold). With no oxygen in the furnace, they do not oxidise in the process (Pfeiffer Vacuum).
- CoolingThe compacted parts cool down in the furnace, then the furnace is vented and unloaded.
Vacuum and sizing
Sintering and debinding: how much vacuum is needed
What the manufacturers say about pressure, pumping speed and sizing.
What vacuum
For sintering, Pfeiffer Vacuum names about 10⁻⁴ hPa.
Binder and vapours
According to Pfeiffer Vacuum, the vacuum extracts the binder; Edwards names removing the binder and compacting. The binder vapours enter the suction flow – a separator or filter upstream of the pump retains vapours and powder dust.
Which pumps
Leybold names DRYVAC with RUVAC WH/WSU and SCREWLINE, Edwards EXS, Busch COBRA, PANDA/PUMA and R5 (18 products in the product finder), Pfeiffer Vacuum DuoVane and HiLobe (19 products), UnoLine Plus (BA 501) as well as the COMBI family.

Sintering and debinding: where the manufacturers name it
The manufacturers list these uses on their own pages.
Metallurgy and heat treatment
Busch, Edwards, Leybold and Pfeiffer Vacuum list sintering and debinding under metallurgy and heat treatment – powder parts are freed of their binder in the vacuum furnace and compacted below the melting point.
Frequently asked questions
Sintering and debinding: frequently asked questions
How does vacuum sintering work?
Pressed powder parts are heated in the vacuum furnace until, according to Leybold, they compact below the melting point. Before that, the binder is removed: according to Pfeiffer Vacuum, the vacuum extracts the binder and prevents oxidation. Edwards describes debinding and sintering as removing the binder and compacting.
How much vacuum is needed for sintering?
For sintering, Pfeiffer Vacuum names about 10⁻⁴ hPa.
Which vacuum pump for sintering and debinding?
Leybold names DRYVAC with RUVAC WH/WSU and SCREWLINE, Edwards EXS, Busch COBRA, PANDA/PUMA and R5, Pfeiffer Vacuum DuoVane, HiLobe and UnoLine Plus (BA 501) as well as the COMBI family.
What is debinding?
The removal of the binder from the pressed powder part before it is sintered. According to Pfeiffer Vacuum, the vacuum extracts the binder; Edwards sums up debinding and sintering as removing the binder and compacting, and names EXS for it.
Why is sintering done under vacuum?
Because there is no oxygen in the furnace: Pfeiffer Vacuum names the prevention of oxidation alongside the extraction of the binder. Leybold describes the result – powder parts that are compacted below the melting point.
What is the difference between sintering and melting?
In sintering, the material stays solid: according to Leybold, the powder parts are compacted below the melting point. In melting, the metal becomes liquid – for this the manufacturers name other processes and in some cases other series.
What can be done if binder vapours get into the vacuum pump?
During debinding, the binder enters the suction flow – Pfeiffer Vacuum describes how the vacuum extracts it. A separator or filter upstream of the pump retains vapours and powder dust.
Which series does Busch name for vacuum sintering?
In its product finder, Busch lists COBRA, PANDA/PUMA and R5 with 18 products for vacuum sintering without describing the process in more detail.
Which pumps does Leybold name for vacuum sintering?
Leybold names DRYVAC in combination with RUVAC WH/WSU as well as SCREWLINE. Leybold describes vacuum sintering as compacting powder parts below the melting point.
A single pump or a central vacuum system?
A central system in a room of its own keeps noise and heat away from production and matches its output to the demand. Central vacuum systems are planned and built by Eugen Theis Vakuum, a company of the Ehrler & Beck group – more under Central Vacuum.
Does Ehrler & Beck also supply spare parts and service?
Yes. Ehrler & Beck offers original spare parts and accessories as well as maintenance and repair.
