Investment Casting for Shipbuilding and Marine Equipment

Ships and marine equipment work in salt water and humidity, so seawater corrosion is the first selection criterion for parts.

Why Investment Casting for Shipbuilding Parts?

Investment casting produces detailed forms such as deck hardware and fittings with a smooth surface. On stainless and bronze parts it also reduces material loss.

Typical Parts

Deck hardware, hinges and locks, valve and pump parts, propeller-area connections, rope and rigging fittings.

Material Selection

316 stainless and aluminum bronze stand out in marine environments. For load-bearing parts, the alloy is selected according to the drawing.

Tolerances and Quality

We cast parts to customer drawings. We can produce parts from 1 g to 25 kg and meet VDG P690 D3, the most precise class of the standard. See our tolerances page for the values.

Design Points for Shipbuilding Parts

• Specify whether the part is in contact with seawater or only exposed to a marine atmosphere.
• Avoid sharp internal corners where corrosion and cracks can start.
• Consider the coating or surface finish when choosing the alloy.

Frequently Asked Questions

Which materials are used for Shipbuilding parts?

316 stainless steel and bronze are common choices for marine conditions.

Which bronze types can you cast?

We cast tin bronze, aluminium bronze and red bronze.

What part sizes and tolerances can you cast?

We cast parts from 1 g to 25 kg and meet tolerances up to VDG P690 D3.

What do you need for a quotation?

A drawing or 3D model, the material and the annual quantity. Price and minimum order quantity depend on the part.
