Abbott Furnace Company manufactures continuous belt sintering furnaces used in the powder metal industry. Sintering is a heat treatment applied to a powder compact in order to impart strength and integrity. The temperature used for sintering is below the melting point of the major constituent of the Powder Metal material.
Jul 07, 2015 · Sinter hardening is conducted inside the sintering furnace itself and involves rapid cooling after sintering to transform the microstructure to martensite. Cooling speeds vary . . . The heat treatment of powder-metal (PM) parts presents a number of unique challenges, influenced primarily by material and density considerations.
Jun 10, 2002 · Vacuum furnaces currently are widely used to process materials where conditions of low oxygen partial pressure and high temperature are required. In these furnaces, a vacuum pump system is used to remove the atmosphere (air) and to achieve oxygen partial pressures in the closed chamber in the range of 10-4 to 10-6 atmospheres.

Dec 13, 2018 · At its root, vacuum sintering involves two things: a vacuum furnace and a combination of metallic powders. By using one properly and mixing the other in the right proportions, several useful properties can be promoted. For instance, sintering can create metallic compounds that reduce the incidence of component failure in machinery or vehicles.
VACUUM FURNACES ADDITIVE MANUFACTURING In 3D printing, metal parts are made by successive layers of metal powders. The rapid cooling following the laser step causes variations in the parts' microstructure, phase changes
The use of vacuum hot pressing sintering is a technological progress, mainly used in: 1, tools such as diamond and cubic boron nitride products: alloy products; metal and ceramic powder high-speed steel products.
This economical sintering tube furnace makes small lab samples from 3D metal printing parts. Choose the right furnace process tube for your application: Alumina (99.5%) tube for tube ID up to 3.5" and max sintering temperature up to 1700C
L. Lu, O. Ishiyama, in Iron Ore, 2015. Abstract. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. In this chapter, the sintering process is first described and the key steps of the sintering process, namely, granulation and thermal densification, are identified.
Electric current assisted sintering (ECAS) is a different type of powder metal manufacturing process that makes extensive use of electric currents and does not require the use of binders. Instead of de-binding or sintering after pressing, electric currents are used to increase the density of the powder, which significantly reduces the thermal cycle needed to maintain the strength and density of the final part.
Fig. 4 Dewaxing/MIM vacuum furnace A large majority of vacuum sintering furnaces are designed as a cold wall, front loading devices equipped with a vacuum pumping system, and equipped with an optional dewaxing system and gas cooling feature. Strong graphite insulation and heating elements provide long, reliable service in this heavy-duty furnaces designed for the industrial work place.
This sintering furnace is suitable for degreasing and sintering production process of hard alloy, high proportion alloy, stainless steel and ceramic powders MIM products; Adopts atmosphere sweeping mode degreasing way, and equipped with special grease sealant tank and wax trap,
Vacuum dewax for hardmetals Developed over 20 years ago, vacuum dewax was the first process to allow debinding and sintering of hard-metals in one furnace, saving production time and cap-ital expense. By using a vacuum and leveraging the low vapour pressure properties of the paraffin wax binder, a fast and efficient debinding process was developed,
The greatest values in vacuum furnaces, used vacuum furnaces, vacuum heat treating furnaces, and vacuum sintering furnaces. The Furnace Source is a manufacturer and reseller of vacuum furnaces, sintering furnaces, vertical bell furnaces, and much more.
Sintering is the bonding of adjacent powder particle surfaces in a mass of metal powders, or a compact, by heating. Also, a shaped body composed of metal powders and produced by sintering with or without prior compaction. Other common names and related subjects are: cold/hot isostatic pressing, liquid phase sintering, and metal injection molding.*
Currently, only about 25 gas fired vacuum furnaces are in operation. High temperature applications that are NOT possible for current gas vacuum technology includes: Sintering (tools and parts made from powdered metal and heated to about 2,400F to harden) and exotic alloy metals used in high temperature applications such as aircraft turbines.
Provides a cleaner atmosphere for sintering since the sintering chamber is segregated from outside air. Metal injection molding furnace A vacuum heat treatment furnace for sintering of powders of alloy steel, stainless steel, and rare-earth for molding etc.
Vacuum sintering is an efficient way to join parts with minimal waste.Vacuum sintering produces consistent, bright parts with no seams, joints, or fillers. Powdered metal, metal injection molding, 3D printing, and other similar technologies can benefit greatly from the superior quality and flexibility of vacuum sintering.
Jul 07, 2015 · The Role of Furnace Atmosphere in Sintering (part 2) Sinter hardening is conducted inside the sintering furnace itself and involves rapid cooling after sintering to transform the microstructure to martensite. Cooling speeds vary by alloy, but rates in the range of 1-2°C/sec. (2-4°F/sec.) from 760-205°C (1400-400°F) are typical.
Vacuum sintering became a relevant technology when first used for the sintering of the Group VA elements – V, W, Ta, Mo, Nb, etc.1 The method was actually a reactive sintering approach where carbon was added to reduce the oxygen from the metal via carbon monoxide evolution under vacuum.
