CNC Manufacturing Capabilities

CNC Tube Bending & Manufacturing Customization Capabilities

Our experienced team of designers and engineers is 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. We 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 & Vacuum Components

Because we manufacture tees, elbows and other weld fittings in-house, Nor-Cal Products can also fabricate exhaust weldments, ion pump bodies and other special assemblies for semiconductor equipment from a single piece of tubing. On request, Nor-Cal Products 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 & Fittings, Traps & 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.

ASME Certified Manufacturing

Nor-Cal Products is proud to be an ASME-certified manufacturer of pressure vessels, including vacuum system components. Our in-house capabilities allow us to monitor each stage of the Engineering, Logistics, Manufacturing and Quality Assurance processes to ensure your vacuum components meet or exceed established industry standards.
 

Vacuum Component Manufacturing Industries Served

As a leader in the vacuum science industry for over 50 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 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 for 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 Nor-Cal 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. Nor-Cal’s welding procedures are based on ASME Section IX with Weld Procedure Specifications on file.
 

Additional Custom Vacuum Manufacturing Services

Intellisys® Downstream Pressure Control

We utilize our Intellisys adaptive pressure controllers and throttle valves reduce time to pressure setpoint while increasing tool throughput with over 100,000 control resolution steps and a 20 times valve speed increase. In addition, we offer a Universal Valve Drive that can be tailored to fit most other manufacturer's valves to greatly improve their pressure control performance at a reduced cost.

Ultra-Clean Vacuum (UCV) Components

Nor-Cal Products 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 by far 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 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.
