Prototype & R&D
One-off and short-run prototype machining for research and development projects. We have supported R&D customers with precision prototypes and tooling since 1980.
Prototype machiningAbout H&B Engineering
H&B Engineering is a woman-owned precision CNC machine shop in the San Fernando Valley. We have machined close-tolerance parts at 8734 Remmet Avenue since 1974.
Our story
Hermann Hartung and William Baumgartner founded H&B Engineering in 1967. By 1973 Hartung owned the company outright, and in June 1974 he moved it into a larger facility at 8734 Remmet Avenue in Canoga Park. The shop still operates from that address. In 1975 the business incorporated as H&B Engineering, a division of Hartung Engineering, Inc.
In January 1980 the company invested in high-quality numerically controlled machinery. The reason was simple: electronics, computer and aerospace customers needed more high-precision parts, and R&D projects needed precision prototype machining and tooling. That investment set the direction for the shop. Today it runs Hitachi Seiki and Fadal CNC machining centers and Hitachi Seiki CNC turning centers, programmed in-house with Gibbs and Mastercam CAD/CAM.
In January 1999, after 20 years working at the company, Daniel and Marjorie Bashaw took ownership and Daniel became President. In May 2001 Marjorie took the title of President and H&B Engineering became a woman-owned corporation. Marjorie oversees business operations and Daniel manages the shop floor.

History
Seven dates that shaped H&B Engineering.
Hermann Hartung and William Baumgartner start H&B Engineering, a precision machine shop in the San Fernando Valley.
Hermann Hartung becomes the sole owner of the company.
The shop moves into a larger facility at 8734 Remmet Avenue, Canoga Park. It has operated there ever since.
The business incorporates as H&B Engineering, a division of Hartung Engineering, Inc.
Growth in high-precision parts for electronics, computer and aerospace customers, plus prototype machining and tooling for R&D projects, drives an investment in high-quality numerically controlled machines.
After 20 years with the company, Daniel and Marjorie Bashaw take ownership. Daniel becomes President.
Marjorie Bashaw takes the title of President and H&B Engineering becomes a woman-owned corporation. Marjorie oversees business operations while Daniel manages the shop floor.
Woman-owned since 2001
H&B Engineering has been a woman-owned corporation since May 2001. The ownership changed. The address, the standards and the kind of work did not.
How we work
We specialize in close tolerance precision production runs and prototype work for the defense, medical, aerospace, automotive and heavy equipment industries.
One-off and short-run prototype machining for research and development projects. We have supported R&D customers with precision prototypes and tooling since 1980.
Prototype machiningClose tolerance precision production runs on CNC turning centers and vertical and horizontal machining centers. Every job gets a shop manufacturing procedure to track each operation.
CNC turning and millingManufacturing of tooling and precision machine parts, backed by a manual machine department with engine lathes, vertical mills, a surface grinder and a lapping machine for secondary work.
See the equipmentQuality control
Our quality control department is maintained in accordance with MIL-I-45208A. All jobs are issued shop manufacturing procedures to track operations, and each operation is inspected per blueprint. Inspection records are traceable and kept for five years. Inspection equipment is periodically calibrated, and calibration reports are maintained. Our Quality Control Manual is available on request.
