Sinter HIP. Hot isostatic pressing of already sintered, but not fully dense samples is used for post compaction. The applied gas pressure of up to 100 bars allows isostatic sintering and removing residual porosity, e.g. for cemented carbides. We can run Ar, N2, H2 atmospheres or vacuum.
20191111"The implementation of the hot isostatic pressing process adds massive value in bringing performance to our car as well as for the demanding needs of our customers. By using Quintus's HIP technology, the Sauber Group will be able to push the boundaries of what we do even further and bring the materials we produce to an outstanding level."

Sinterbar™ Jr. Pressure Furnaces are vital to the efficient and economical production of a wide variety of advanced ceramics, carbide tools and wear parts, and other high performance materials. They eliminate a separate hot isostatic pressing operation for many materials with liquid phases.
The furnaces combine two technologies in one machine: Vacuum sintering and hot isostatic pressing of sintered parts. In addition to the standard pressure ratings of 60 bar and 100 bar, Sinter HIP Furnaces with process pressure of 200 bar are available for extremely low-cobalt types of cemented carbide.
red by two different techniques (conventional furnace and hot isostatic pressing (HIP)). All samples showed an identical peak position and peak shape. Furthermore, all samples show the formation of KNN perovskite structure and a typical orthorhombic symmetry without secondary phase, which is similar to results obtained by Wang et al. .
Hot isostatic pressing (HIP) takes various forms: A solid-state PM process for simultaneously heating and forming a fully dense part either by: a. Encapsulating powder in an evacuated and hermetically sealed sheet metal canister, or b. Sintering a pressed or CIPed compact to high enough density to allow unencapsulated HIP to achieve full density.
During Hot Isostatic Pressing (HIP), the material to be processed is heated up in special plants (HIP plants) under argon atmosphere, high gas pressure and under high temperatures exceeding the yield point in order to compact the component. For most materials, the process pressure is approx. 1000bar = 100MPa and temperatures are up to 1400°C.
2016526The corner includes an inner surface comprising a radiused portion by which the main region smoothly transitions into the lip. A hot isostatic pressing canister including at least one of the endplates also is disclosed, along with a method of hot isostatic pressing a metallurgical powder using the hot isostatic canister.
Hot isostatic pressing (HIP): HIP is commonly used to achieve full densification of the desired material. Among the advantageous of this sintering technique, it should be noted the high isostatic pressure (up to 350 MPa) at high temperature (1900 °C), which allow to remove the close porosity.
Densification model of titanium alloy (Ti-6Al-4V) are investigated during hot isostatic pressing (Hip). Experimental data was obtained at various pressures and temperatures during hot isostatic pressing (Hip). Experimental data are compared with the finite element calculations by using the hybrid model and Abouaf model, respectively. The
dewaxing, vacuum sintering and the subsequent isostatic pressing of metals, carbides, alloys and ceramics are main products of the Industrial Systems Divison. Metallic heated high-vacuum heat treatment furnaces (MOV), designed for typical applications like vacuum bra-zing, degassing, sintering and cleaning are further successful products.
We have been fabricating ceramics by five kinds of sintering methods including air sintering, hot-pressed (HP) sintering, mold pressed (including CIP (Cold Isostatic Press) sintering, spark plasma sintering (SPS) and hot isostatic pressing (HIP) sintering.
2016315One of the major problems of the silicon nitride processing is the high cost of such commercial methods as hot isostatic pressing (HIP), spark plasma sintering (SPS), and gas pressure sintering (GPS). Thus, it is important to find new and cheaper alternative processing methods while a relatively high strength can be acquired.
201956Most importantly, some materials require the use of a hot isostatic pressing (HIP) process directly after sintering. HIP demands high pressures ranging from 30-150 bar and dramatically reduces the porosity of the materials being handled by increasing their density. Ensure that you Make the Right Vacuum Sintering Investment. Both HIP and high
Hot Isostatic Pressing (HIP) modeling to produce near net shapes should provide a more economical route for exploiting the benefits of Alloy 690N~. The efforts involved in developing and verifying the P/M Alloy 690N2 HIP model are disclosed. Key to the deployment of HIP modeling is the development of the
Welcome to the most trusted and comprehensive Furnaces: Pressure Sintering directory on the Internet. A broad range of Furnaces: Pressure Sintering resources are compiled in this industrial portal which provides information on manufacturers, distributors and service companies in the Furnaces: Pressure Sintering industry.
Hot isostatic pressing (HIP) is a process using high pressure and temperature over a set time to improve material properties. Precisely computer controlled to specific parameters yield the desired improved properties. A furnace is inside a pressure vessel is pressurized with argon.
