Windform^® PS is a new polystyrene based material, suited to produce complex investment casting patterns. The sintered patterns are enough porous in order to allow the convenient wax infiltration, and therefore becoming easy to handle and to finish.

Windform^® PS patterns can undergo the typical rapid casting procedure, including autoclaves and flash firing steps, low-temperature furnaces and vacuum plaster casting methods.

Improved properties, compared to other polystyrene materials already available on the market, and that make the difference, are:

• Improved surface quality and details reproduction
• Less “curling” effect on the first layers
• Very low ash content, therefore perfect suitable for highly reactive alloys, such as Titanium alloys too, besides aluminium, magnesium, steel and nichel base alloys.

 

The recommended wax is a standard 100% paraffin wax (with melting point of about 54°C) and infiltration is for about 10” @ 70°C.

FS Precision Tech is an investment casting foundry.

They cast complex castings for CRP in both Titanium and Steel. Greg Gregory, Technical Director of FSPT said “I find that Windform PS material works well with our process and produces castings of equal or greater quality than the standard material.
FSPT would recommend using Windform PS as the rapid prototype material for any casting house”.
