CNC Manufacturing Capabilities

At Pfeiffer Vacuum Valves & Engineering, our skilled designers and engineers are committed to delivering top-quality vacuum system components tailored to your unique application needs. Leveraging advanced computer numerically controlled (CNC) tube bending technology, we offer: Our CNC tube bender enables precise forming of elbows and custom exhaust weldments, facilitating multiple compound angle bends in a single tubing piece. We offer customization options for tubing diameters, accommodating both standard and metric specifications.

Custom Weldments and Vacuum Components

With in-house manufacturing capabilities, we fabricate tees, elbows, and other weld fittings, allowing for the seamless production of exhaust weldments, ion pump bodies, and special assemblies for semiconductor equipment. Our team can also assemble complete one-off systems to your specifications, including chambers, frames, pumps, gauges, valves, and manipulators.

Vacuum Manufacturing Materials Selection

We utilize only the finest-grade materials for vacuum component manufacturing, considering factors such as vapor pressure, permeability, and corrosion resistance. Our materials include select grade 304 stainless steel tubing, spheres, or roll-ups, with options for 304L, 316L, or 316LN if required. Flanges and baseplates are meticulously crafted from specially treated 304 stainless steel to meet ASTM A-240 standards.

Custom Vacuum Fabrication

Our state-of-the-art CNC machining equipment ensures consistent, high-quality parts production. We employ advanced techniques such as die-formed ports using the pulled-port method and orbital welding for precise weld penetration. Welding procedures adhere to ASME Section IX standards, with Weld Procedure Specifications on file for reference.
