Sintering Equipment

In the sintering process, raw material powders with a purity of 99.9% to 99.999% are typically used.
Oxide sputtering targets and tablets are mainly manufactured by atmospheric sintering.

This is a device that fills powder into a specified mold and performs uniaxial forming.

By adopting a 3-cylinder system, pressure control is possible over a wide range from 100 to 10000 kN.

Precision hydraulic control can suppress the effects of springback, and program control enables highly repeatable forming operations.

• Precision hydraulic control can suppress springback.
• Program control enables highly repeatable forming operations.

This is a device that performs forming by isostatic pressure within a cylinder.

Because high-pressure forming is performed, compacts with minimal density variation can be obtained even in large sizes.

A wide range of applications is possible, from small-lot to mass production, and from small to large products.

• Processing is possible up to approximately φ500 mm × L1000 mm.
• Pressurization up to a maximum of 200 MPa (2040 kgf/cm²) is possible.

Characteristics

• Unlike die forming, there is no friction with metal, and because pressure acts isotropically, compacts with uniform density and minimal directionality can be obtained.
• The depressurization process allows optimal conditions to be set through primary depressurization by valve and program-controlled secondary depressurization (to prevent cracking due to springback).

Vacuum hot pressing is one of the pressure sintering methods.

This is a device that fills powder into a carbon mold and performs sintering by simultaneously applying heat and pressure.

In the initial heating stage, degassing is performed in a vacuum, followed by sintering in an inert gas atmosphere.

Characteristics

• Since degassing is performed in a vacuum during the initial heating stage, followed by sintering in an inert gas, metal oxidation can be prevented.
• This sintering equipment offers excellent reproducibility through program control.

Main Products

• Easily oxidizable metals such as W-based, Mo-based, Nb-based, V-based, and Ta-based
• Oxygen-deficient oxides such as TiOx, NbOx, etc.

Spark Plasma Sintering (SPS) is a pressure sintering method that uses pulsed electrical current. By utilizing self-heating of the workpiece through pulsed electrical current and discharge plasma energy generated between particles, rapid and dense sintering is achieved in a short time.

• Sintering without binder (sintering aids) (AlN, TiN, W-Ti, Si₃N₄, etc.)
• Sintering of composite materials and multi-component materials (oxide + metal, nitride + metal, etc.)

• Sintering of nanostructured materials
• Application to porous materials

• Bonded Sintered Bodies

  

  Since SPS can create temperature gradients within the same mold, sintering of functionally graded materials is also actively performed.

• Difficult-to-Sinter Materials / Easily Decomposable Substances

  

  Even materials that are difficult to densify through sintering or materials where thermal decomposition at high temperatures is a concern, can be sintered without structural degradation using SPS.
