Sintering

TITAN DS - Debind and Sinter

TITAN DS, Ipsen's new debinding and sintering furnace, upholds the company’s reputation for better performance, quality and better features for less cost. It also enables higher volume in-house sintering.

Vacuum Debinding and Sintering

Get the breakdown on how the VFS model VDS (Vacuum Debind/Sinter) and Ipsen TITAN DS each tackle problematic binder buildup and contaminants. The unique design of these furnaces delivers more consistent and superior part quality.

VFS - VDS

A unique dual vacuum pump design that incorporates two steps - debinding and sintering - into one furnace, one cycle, without contamination of the components, hot zone or furnace chamber.

Critical Process Parameters for MIM

Analyzing different factors for determining unwanted temperature gradients in MIM vacuum furnaces makes it possible to evaluate the process parameters and provide possible improvements.  This is done by utilizing tight control and accurate design of hot zones and heating elements, as well as enhanced process gas management systems, for commercial use in large series production environments.

Processes

Brazing

High-grade stainless steel, aluminum and ceramic products can only be manufactured in an economically and environmentally sound manner using vacuum brazing.

Additive Manufacturing

Ipsen and a global provider of 3D printing machines and printed products began a partnership in 2013.  It was part of an initiative to streamline production in the field of Additive Manufacturing and provide customers a complete three-dimensional (3D) printing package.

Nitriding and Nitrocarburizing

Work began, 10 years ago, on the development of a gas nitriding and nitrocarburizing process control system that has the potential to monitor deviations in the gas atmosphere of the furnace.

Product by Process Matrix

At Ipsen, it is essential to provide customers with products that will provide them with the best possible results for their unique requirements and processes. Using Ipsen’s product by process matrix will help determine which equipment best fits the customer’s requirements.

Sintering

Vacuum furnace technology presently exists to debind and sinter in one process cycle, not only saving money and time of the heat treaters, but also resulting in more consistent superior part quality.

AvaC - Acetylene Vacuum Carburizing

AvaC is an established process for vacuum carburizing with acetylene.

Other applications include Thermochemical Diffusion, Aluminum Vapor Deposition and Heat Treating Stainless Steels.

Innovations

HybridCarb

In the currently available atmospheric gassing systems using endothermic gas or nitrogen/methanol, only 2% of the gas is in fact diffused into the workpieces, 98% remains unused and is burned off and discharged into the atmosphere. Making improvements and changes to be more green can be a hassle, but Ipsen's HybridCarb gassing system is one of the few green technologies that can be implemented in an effortless manner, and it allows users to begin saving right away.

AvaC

Ipsen's AvaC (acetylene vacuum carburizing) is a technology exclusive to Ipsen that uses acetylene to practically eliminate tar and soot, while majorly increasing carburizing power even for blind or through holes. AvaC process configurations are optimized for maximum results and comes with a variety of features and options so it is possible to get the best out og the vacuum carburizing furnace.

Directional Cooling

The Ipsen SuperTurbo® horizontal vacuum furnace plays a vital role in achieving minimum distortion at optimal cooling performance levels. The blending of directional cooling, high quenching pressure and Ipsen's water-cooled motor with LCP start-up permits hardening of heavy loads with major gains in part quality. The SuperTurbo will help improve the process.

Heating Elements

Ipsen’s patented GraForm curved graphite heating elements for VFS model vacuum furnaces represent a significant breakthrough for the thermal processing industry. GraForm elements are significantly thinner than conventional straight graphite elements, and because of this they have a lower mass. This results in delivering an extremely responsive system with operational consistency.

Quench Nozzles

Another innovation has been offered by Ipsen for use in VFS model furnaces. ThreadFast gas quench nozzles are specifically designed to provide the least restrictive gas flow path into the vacuum furnace work zone. ThreadFast gas quench nozzles, available in ceramic or graphite, provide a cost-effective and more durable alternative to standard moly nozzles.

Convection Heating

Ipsen’s new flapper nozzle and latest convection heating design are technological breakthroughs. The flapper nozzle system, a convection turbo-gas outlet port, is reliable and simple. It does not need complex linkage or actuation mechanism. It continues to be in a closed position unless when cooling, thus decreasing heat loss from the hot zone while enhancing temperature uniformity during heating.

Hearth Rails

The improved graphite hearth rails from Ipsen are specially designed to handle extremely large workloads at high temperatures. Heat treaters had to depend on molybdenum rails for heavy loads before this innovation. However, this issue has been successfully eliminated by Ipsen. This is another innovation Ipsen has introduced in order to make vacuum heat treating more reliable and minimize maintenance.
