CNC Manufacturing Capabilities

CNC Tube Bending & Manufacturing Customization Capabilities

Our experienced designers and engineers are dedicated to producing the highest quality, ISO 9001:2015-Certified vacuum system components to meet your application requirements. We utilize a computer numerically controlled (CNC) tube bender to form elbows and custom exhaust weldments. This enables us to quickly make multiple compound angle bends in a single piece of tubing. We can customize weldments and vacuum components with custom or metric tubing diameters upon request. PV V&E can manufacture vacuum components to meet low to high-volume orders and form fulfill Ultra-Clean (UCV) components. Our additional strong in-house capabilities support the quality of our components and services in a variety of areas, including Engineering, Logistics, and Quality Assurance.

Custom Weldments and Vacuum Components

Because we manufacture tees, elbows, and other weld fittings in-house, Pfeiffer Vacuum Valves & Engineering can fabricate exhaust weldments, ion pump bodies, and other special assemblies for semiconductor equipment from a single piece of tubing. On request, PV V&E can assemble an entire one-off system to customer specifications, including:
  • Chambers
  • Frames
  • Pumps
  • Gauges
  • Valves
  • Manipulators

Quality Control

ISO Certified Manufacturing

Nor-Cal Products is an ISO 9001:2015 certified manufacturer of high and ultra-high Vacuum Chambers, Vacuum Flanges and Fittings, Traps and Filters, Feedthroughs, and more. We take all the necessary quality control and inspection steps required to ensure that you receive high-performance vacuum components that meet your project demands.

Vacuum Component Manufacturing Industries Served

As a leader in the vacuum science industry for 60 years, we have gained a reputation for manufacturing precise vacuum components for various industries, including:
  • Semiconductor industry
  • Research laboratories
  • Equipment manufacturers
  • Energy and aerospace
  • Life and health sciences development

Vacuum Manufacturing Materials Selection

Nor-Cal Products, Inc dba Pfeiffer Vacuum Valves & Engineering uses only the highest-grade materials to manufacture vacuum components. Vapor pressure, permeability, and corrosion resistance are important considerations taken into account during the material selection process. We start with select grade 304 stainless steel tubing, spheres, or roll-ups to fabricate the vacuum component. If required, parts made of 304L, 316L, or 316LN can be supplied. Normally, our standard material is in the low carbon range of 304. Flanges and baseplates are made from 304 that has been specially treated to remove impurities inherent in 300 series steels. Our standard flange material is certified to meet ASTM A-240.

Custom Vacuum Fabrication Capabilities

All PV V&E components are designed to minimize entrapments, which may cause virtual leaks under high vacuum conditions. Our state-of-the-art CNC machining equipment is available to produce parts with consistently high quality. Most valve and trap body ports and weld fittings are die-formed using the pulled-port method. Orbital welders are also available for precise weld penetration. Our welding procedures are based on ASME Section IX with Weld Procedure Specifications on file.

Additional Custom Vacuum Manufacturing Services

Ultra-Clean Vacuum (UCV) Components

Pfeiffer Vacuum Valves & Engineering is one of a small handful of companies in the world that can precisely measure outgassing rates of a wide range of atomic mass units (AMU’s) from 1-200 using a highly precise, state-of-the-art RGA test stand.

Electropolishing / Surface Treatments

Electropolishing is the most desirable cleaning process for stainless steel vacuum components. This electrochemical process maintains critical dimensions while improving surface finishes.

Cleanroom Assembly & Packaging

Nor-Cal Products, Inc dba Pfeiffer Vacuum Valves & Engineering is an ISO 9001:2015 certified company and can offer cleanroom assembly, cleanroom packaging, and CMM printouts of each vacuum chamber’s final inspections can be furnished upon request.

Why Choose PV V&E?

Pfeiffer Vacuum Valves & Engineering is dedicated to the continual improvement of our prototyped and manufactured goods through the implementation of a carefully planned quality management system. Our strong in-house capabilities support the quality of our components and services in a variety of areas, including Engineering, Logistics, Manufacturing, and Quality Assurance.
