Frequently Asked Questions

Hot Isostatic Pressing (HIP) is a well-established manufacturing process that utilizes high pressure and temperature to improve the properties of various materials. It works by simultaneously applying intense pressure from all directions (isostatic) while also using high temperature to reduce or eliminate voids within materials like castings, or to consolidate powders into dense solids. This results in materials with improved density, mechanical properties, and overall performance.

PTI is experienced in HIP processing of a wide range of materials, including titanium, steels, aluminum, superalloys, intermetallics, and various metal powders. We handle materials used in investment castings, powder metallurgy, additive manufacturing, and metal injection molding (MIM). Additionally, we work with both similar and dissimilar material combinations in the process of diffusion bonding.

PTI provides HIP services for a wide array of industries including aerospace, medical, space, oil and gas, automotive, electronics, and power generation. Specific applications include: densifying castings and metal powders, enhancing the properties of 3D printed parts and MIM parts, and creating diffusion bonds in solid/solid and powder/solid combinations. The HIP process improves the mechanical properties of these parts for their intended applications.

PTI operates 13 HIP units with capabilities of up to 30 inches in diameter and 105 inches in length. The units can apply pressures up to 30,000 psi (207 MPa) and reach temperatures up to 2550°F (1400°C). We offer a range of processing capabilities from small low pressure to large high-pressure production.

PTI maintains a comprehensive quality control program and is certified to meet ISO 9001, AS9100, and Nadcap standards. We are also approved by major aerospace manufacturers such as Pratt & Whitney, GE, Safran, Honeywell, Rolls-Royce, and Siemens, demonstrating a commitment to high-quality processing.

HIP is effective in reducing or eliminating voids and porosity in castings. This densification leads to increased strength, improved fatigue resistance, and enhanced overall performance of the casting. These improved properties make the castings more reliable and longer lasting.

PTI emphasizes responsiveness, reliability, and fast turnaround times for customer projects. We offer shared cycle capabilities to help reduce costs. We aim to provide world-class quality and reliability while enabling their customers to focus on their core business activities.

PTI has locations in Warminster, Pennsylvania; Concord, Ohio; and Alachua, Florida. This allows us to service customers across the United States and international
