01 / WHY MOCKUP FOR MARINE

Why Manufacture Marine Parts With Mockup?

Marine components operate around saltwater, humidity, vibration, mechanical loads and continuous environmental exposure.

Mockup coordinates manufacturing, finishing and inspection from prototype and vessel development through replacement parts and repeat production.

Corrosion-Resistant Materials

Machine stainless steel, marine aluminum, bronze, brass, titanium and specified materials for the operating environment.

Propulsion & Motion Components

Manufacture shafts, couplings, bearings and housings where alignment, concentricity and fit influence performance.

Fluid & Sealing Interfaces

Control valve bodies, pumps, manifolds, threads, ports and sealing surfaces used throughout marine systems.

Marine Structures & Hardware

Combine CNC machining and fabrication for brackets, mounts, deck hardware, structures and enclosures.

Replacement Part Support

Support low-volume replacement and service components where standard catalog parts are impractical.

Finishing & Inspection

Coordinate passivation, anodizing, plating, polishing and coatings with dimensional requirements.

05 / BUILT AROUND THE MARINE ENVIRONMENT

Saltwater Changes the Manufacturing Decision

Material, finish and interface design must account for saltwater, dissimilar metals, vibration, wear, sealing and long outdoor exposure.

01

Saltwater Corrosion

Continuous moisture and chloride exposure can accelerate corrosion on unsuitable alloys or poorly protected surfaces.

02

Galvanic Corrosion

Dissimilar metals connected in seawater require compatible material combinations and isolation strategies.

03

Vibration & Cyclic Loads

Propulsion systems, engines, pumps and deck machinery expose components to repeated mechanical loads.

04

Wear

Shafts, bushings, bearings and moving hardware need material and surface combinations suited to movement.

05

Sealing

Pump, valve, hydraulic and subsea components rely on controlled sealing surfaces, grooves and threads.

06

Outdoor Exposure

Deck hardware and structures must tolerate salt spray, UV, rain and temperature changes.

06 / PROPULSION, STEERING & DECK SYSTEMS

Manufacturing Around the Systems That Move and Control the Vessel

Propulsion, steering and deck components combine controlled fits and alignment with demanding loads and environmental exposure.

01

Propulsion Systems

Propeller shafts, shaft couplings, sleeves and related parts manufactured around alignment, fits and load transfer.

02

Steering Systems

Rudder stocks, pins, bushings, tiller components and steering hardware with controlled interfaces.

03

Pumps & Fluid Systems

Pump housings, impellers, manifolds, valves and fittings for cooling, hydraulic and seawater systems.

04
