Refractory Specialties has been expanding the use of high temperature insulation and refractory products for years. Continually developing products for industries where heat needs to be directed or contained, RSI can create products that withstand 2,100 to more than 3,000 degrees Fahrenheit.

Refractory Specialties offer a variety of manufacturing and prototyping capabilities. Powdered metal sintering is one way to form ceramic objects. According to Dictionary.com, sintering is “to form large particles, lumps, or masses, from metal powders or powdery ores, by heating or pressuring, or both, to a temperature lower than its melting point.” Powdered metal sintering allows for intricate, multi-level parts with greater mechanical, strength and fatigue properties.

Powdered metal sintering is being used more often because there are many advantages to using the material powdered metal.

Powdered Metal Advantages

  • Chip-less metal working process results in near-net shapes
  • Minimal machining
  • Minimal scrap
  • Close dimensional control
  • Large variety of material compositions
  • Self-lubricating properties through controlled porosity
  • Comparable performance characteristics to competitive technology
  • Proven cost-effective solution
  • Complex, multi-level shapes possible
  • Design flexibility
  • Withstands fire
  • Endures natural elements
  • Strength and durability properties

Powder metal sintering can create many different products. It can produce lawn and garden tools like irrigation, sprinkler rotors, pattern adjusters, shoes, and spray nozzles. It can also form tools like grips, cutters, saw tips, wrench components and knife bolsters. Powder metal sintering can make hardware too, like dead bolts, latch bolts, cams and levers. Sintering is known to be used to create products for the automotive, lawn and garden, hand tools, irrigation, lock hardware, medical, computer and cutlery industries.

Refractory Specialties are known for using powder metal sintering on a material called Sinterlyte. Sinterlyte is a “lightweight porous kiln setter for temperature applications up to 1600 degrees Celsius (2900 degrees Fahrenheit).” This material can be covered in three different coatings to eliminate dusting and provide a more wear resistant surface. When this material is formed, it can be made into sheets, custom shapes or corrugated plates. Sinterlyte is great because it conserves energy with its low thermal conductivity and heat storage. Sinterlyte also cannot be cracked, when sintered, because it has thermal shock resistance.
