Custom Engineered Precast Refractory Shapes

We specialize in crafting custom-engineered precast refractory shapes designed to meet the rigorous demands of industrial environments.

Precast Solutions

Onex designs and manufactures custom precast refractory shapes for the world's most demanding high-temperature applications from individual replacement components to fully engineered modular refractory systems. We combine advanced engineering including rapid mold making technology, precision manufacturing, premium refractory materials, and rigorous quality control to deliver precast solutions that reduce downtime and maximize operational performance.

Engineering-Driven Design

Using SolidWorks®, Autodesk Inventor®, CAD modeling, 3D scanning, CNC machining, and rapid prototyping technologies, we develop precision molds and engineered refractory solutions that fit correctly the first time and perform reliably in service. We can also reverse engineer existing components to improve durability, manufacturability, or installation efficiency. Our engineering team works closely with customers to evaluate:

  • Operating conditions

  • Thermal cycling requirements

  • Mechanical loading

  • Chemical exposure

  • Installation methods

  • Maintenance accessibility

  • Expected service life

Our Proven 5-Step Precast Process

We’ve perfected a step-by-step process to guarantee the quality and longevity of our precast refractory shapes:

STEP 1:

Precast Design Engineering

Engineering Design

Our team works with you to understand your needs and develop long-lasting refractory shapes tailored to your operational requirements. We source the best refractory materials to meet your project needs.

STEP 2:

Precast Rapid Prototyping

Rapid Prototyping

With advanced technologies, we create high-precision molds using materials like wood, steel, rubber, nylon, and styrofoam, ensuring quick turnarounds without compromising quality. No matter your dimensions, we have the solution.

STEP 3:

Precast mixing & vibrating

Mixing & Vibration

We carefully select refractory materials from a range of manufacturers to ensure the right mix for your application. Our advanced mixers and vibration tables ensure air is removed and the mix is perfectly set.

STEP 4:

Precast Furnace Curing

Cure & Dry Out

Once the precast shapes are poured, they go through a precise curing process. Afterward, they are dried in our furnaces, which fire up to 2000°F and use slow cool down cycles to ensure each shape sets perfectly.

STEP 5:

Precast_Packing

Packaging & Shipping

We provide tailored shipping options, offering custom branded packaging to maintain your professional image. Our team carefully packages and schedules deliveries throughout the US, ensuring your parts arrive in perfect condition.
