Vacuum Sintering Furnace for Carbides

About Vacuum Sintering Furnace for Carbides

Vacuum Sintering Furnace for Carbides manufactured by United Enterprises is a specialty vacuum furnace built for sintering of tungsten carbide (WC-Co) and other hard metal compositions to near-full density.

Brief Description:

Tungsten carbide tools, dies and wear parts demand near-full density, controlled porosity and precise metallurgy. Our Vacuum Sintering Furnaces for Carbides are designed to deliver this through high-vacuum sintering, optional sinter-HIP capability and tight temperature uniformity.

Built with graphite heating elements, multilayer insulation, high-vacuum pumping systems and integrated gas quench (with optional 100 bar HIP capability), these furnaces handle carbide grades from coarse to ultra-fine.

Each unit is engineered around the customers grade, batch size and production volume.

Characteristics:

• Designed for WC-Co and hard metal sintering
• Maximum temperature up to 1600C
• Working vacuum down to 10 mbar
• Optional sinter-HIP capability (up to 100 bar)
• Graphite heating elements
• Multilayer insulation package
• Multi-zone PLC and SCADA temperature control
• Designed for high-density carbide parts

FAQs:

Q: Sinter or sinter-HIP for tungsten carbide?

A: Sinter-HIP is the modern standard for premium carbide; standard vacuum sintering is sufficient for general grades.

Q: How is full density achieved?

A: Through controlled sintering temperature and time, supported by sinter-HIP under high gas pressure where required.

Q: Do you support trial sintering?

A: Yes. Pilot trials, density measurement and metallography are supported at commissioning.
