Investment Removal
Investment removal is primarily used in industries that require high precision parts, with complex geometries.
Benefits of Investment Removal
Guyson work with numerous companies processing high precision parts, in industries such as aerospace, automotive, defence and medical, to perform investment removal. Removing investment from components is vital for ensuring the part is operational.
- Reveals a smooth surface finish to the component
- Minimises contamination of residual ceramic material that could otherwise affect the part’s performance
- Improves coating and plating adhesion
Guyson’s Investment Removal Examples
- The Guyson Pencil Blaster performs localised conformal coating removal from PCB boards during repair work, as well as phosphate bonded casting investment removal from cobalt chrome crown and bridge cases by dental technicians
- Guyson’s Formula Bead Blast machines are utilised for performing investment removal on dental castings
- Guyson’s Euroblast systems are commonly used for removing investment from castings on applications that require longer working blast sessions
- Grit blasting, using abrasive blast media, is often used for industrial applications, such as to perform investment removal in the fettling of castings

FAQs
Why is shot blasting used for performing investment removal?
Shot blasting is used for investment removal because it efficiently removes the ceramic shell on the surface of the component, helping to remove oxide layers, scale & welding residues, revealing a thoroughly cleaned, non-contaminated surface. Shot blasting therefore becomes fundamental for these processes as it enhances the components adhesion and durability for subsequent coatings required.
Which Guyson shot blasting machines have been used for performing investment removal?
Guyson Pencil Blasters have been used for localised conformal coating removal from PCB boards, Guyson Formula Bead Blast Machines have been utilised for investment removal from cobalt chrome crown and bridge cases by dental technicians, and Guyson Euroblast systems are commonly used for removal from castings.
