About Weistec Engineering
Performance-driven since 2010
Weistec started as a performance-driven automotive innovator, designing, developing, validating and producing high-end performance products. Today we apply that expertise across industries as a provider of turnkey engineering, manufacturing and prototyping services.
Our team brings mechanical, electrical, electronic and systems engineering experience that applies across transportation and aerospace. The result is a partner that combines the responsiveness of a small shop with industry-leading design and production tools.
Keeping engineering, machining, fabrication and inspection in the same building means shorter lead times, tighter control and one point of contact for the whole job.
Engineering & Simulation
CAD/CAM for mechanical design and efficient toolpath generation
FEA for fluid dynamics, static and dynamic loading, thermal cycling and heat transfer
Design for manufacturability to optimize complex components for performance and production
CNC Milling: 3, 4 & 5-Axis
Haas UMC-750: full simultaneous 5-axis for impellers and propulsion housings

Rapid Prototyping (NPI)
SLA 3D printing for complex geometry, fit checks and casting patterns
Fast turnaround from digital design to physical prototype
Fast path from prototype to machined or cast production parts
Tuning, Calibration & Certification
Calibration & certification
Vehicle calibration is where Weistec started. Our engineers develop and validate engine and transmission calibrations in-house, and the same team supports OEM and aftermarket programs that need electronic calibration, vehicle certification and emissions work.
ECU and TCU calibration: engine and transmission software developed and validated in-house, delivered through Cypher Plus and Cypher Pro
Electronic calibration for OEM, prototype and aftermarket control systems
Vehicle certification testing and documentation support
Emissions testing and certification support for performance parts and vehicle programs
Featured Project
Large-format 7075 aluminum, machined in-house
Large, complex housings machined from solid 7075 aluminum billet on our 5-axis machining centers. 7075 delivers exceptional strength for its weight, and 5-axis machining lets us bring bearing bores, mounting points, sealing surfaces and weight-saving pockets together in a single part. Programming, fixturing and machining are all done under one roof.

Aerospace & Defense
Motorsport-proven engineering for flight and defense hardware
Weistec built its reputation designing and validating high-output powertrain components that have to survive extreme heat, pressure and RPM. We apply the same engineering and manufacturing discipline to aerospace and defense programs.
Precision 5-axis machining of titanium, Inconel, aluminum and stainless steel for complex aerospace systems
Propulsion and fluid systems: laser cutting plus laser, TIG and MIG welding for propulsion delivery hardware
Engineering and simulation: FEA for fluid dynamics, static and dynamic loading and heat
Metrology: 3D laser scanning and CMM for dimensional, profile and angularity verification
Aircraft integration: helicopter camera mounts and cabin equipment installs, designed and built in-house

Private Label & OEM
Your brand. Our engineering and production.
We design, engineer and manufacture the Weistec product line in this facility, and we can do the same for your product. Bring an idea, a sketch or an existing part, and we'll take it through engineering, prototyping, production and inspection, delivered ready to sell under your name.
Design and engineering: CAD, simulation and design for manufacturability
Prototype and validate: rapid prototypes for fit and function before tooling up
Production: CNC machining, sheet metal, welding and assembly in-house
Inspection: measured and verified before it ships to you
