PBTT Corp is a manufacturing company headquartered in Newburgh, Indiana, committed to green manufacturing, professional integrity, and open communication. Founded in 2013, the company has expanded across several industries, including automotive, aerospace, defense, and energy, delivering disruptive technologies and consolidation services that exceed customer expectations in quality, safety, and sustainability. PBTT Corp provides vertically integrated solutions that span machining, finishing, heat treatment, deburring, tumbling, and anodizing, serving customers who demand precision and reliability. Its multi-axis machining capacities, automated loading and inspection systems, and dedicated machining centers position it as a trusted partner for complex, high-tolerance production. The following article examines PBTT Corp’s proprietary Nanoform manufacturing process, a suite of advanced sintering and compaction technologies used to produce extremely precise, fully dense components from ceramic, alloy, and composite inputs for industries ranging from automotive to medical.
A Look at the Nanoform Manufacturing Process
PBTT Corp. delivers highly technical engineering and manufacturing processes ideal for prototyping and commercial production of critical components in industries ranging from automotive to medical. Its trademarked Nanoform manufacturing processes use ceramic, alloy, and composite inputs to deliver advanced shapes and unique processing profiles.
The Nanoform process puts input materials through temperatures of at least 2000 degrees Celsius, which creates liquid bonds between powder particles. At the same time, compression pressures of greater than 50 tons fuse semi-solid materials into blanks that are net-shaped and near-net-shaped. This is accomplished without the semi-solid materials ever entering a fully liquid phase.
Oxidation and contamination issues are resolved through processing the parts within a vacuum, with forming and cooling taking place under high pressure. The result is structures that are 100 percent theoretically dense, with true position calibrated to within 0.001 percent of an inch. Across 4-inch blank lengths, the hardened material offers superior +/- 0.001 inch linear tolerance. This makes parts produced in this way potentially very small and extremely precise.
The range of Nanoform services spans treatment and hardening of metals and/or ceramics through sintering processes. Sintering is a heat treatment process that works at the atomic level, with materials’ atoms diffusing along the boundaries of particles, fusing together to create a single piece. Often associated with the creation of minerals through volcanic processes in nature, this phenomenon translates to the manufacturing realm when heat and pressure are applied together on target materials, whether ceramics, metals, or plastics. It is ideal for metals that have high melting points, from tungsten to molybdenum, as sintering typically does not attain the melting point of such materials.
The ideal sintering point for any given material is the temperature range at which heat and pressure combine to eliminate most of the porous spaces between materials. What was once loose material has been squeezed to the max and engineered into a stable, durable solid mass.
PBTT Corp. provides a number of sintering options, including field assisted sintering technique (FAST), spark plasma sintering (SPS), plasma pressure compaction (P2C), and pulsed electric current sintering (PECS).
An emerging technology, FAST pairs higher heat rates with lower sintering temperature. As its name suggests, this results in faster process times, as well as reduced grain growth. The latter aspect is critical, as it enables the retention of nanoscale features within nanomaterials.
With spark plasma sintering (a form of FAST), pressure is combined with an electric field, which boosts metallic powder and ceramic compaction density. It’s worth noting that SPS hot pressing techniques do not actually require the use of plasma.
Plasma pressure compaction also features ultra-fast heating rates (as fast as 1000 degrees C/s). It utilizes a pulsed direct current that bypasses the limitations of traditional sintering furnaces, which have extended heating cycles. The pulsed direct current combines with mechanical pressure to generate an extremely fast sintering process that avoids material degradation. Whatever the process applied, PBTT Corp. strives to ensure the highest quality at an extremely economical price point. This makes its services sought after in sectors that range from industrial operations to automotive manufacturing.
