Investment Shell Manufacturer

Investment mold shell refers to the mold shell for investment casting, also known as wax loss casting, including wax pressing, wax trimming, tree formation, slurry dipping, wax melting, casting liquid metal, and post-treatment. When the mold is lost, the shell will be under the pressure of the increasing volume of molten mold material; During roasting and pouring, each part of the shell will produce mutually restrained and uneven expansion and contraction. Therefore, the metal may also have a high-temperature chemical reaction with the shell material. Therefore, the shell has specific performance requirements, such as low expansion rate and shrinkage rate, High mechanical strength, thermal shock resistance, fire resistance, and chemical stability at high temperatures, so the refractories used in investment casting are mainly quartz and fused alumina.

Investment Shell FAQ

What is the hardness?

Hardness is rated from A-Z with ‘A’ being the weakest bond and ‘Z’ being the strongest.  A weak bond is preferred for grinding harder materials while  a stronger bond is desired for softer materials.  A typical weak bond for steel would be in the ‘F, G or H’ range.  A

What is fepa and what does it do?

FEPA is the Federation of European Producers of Abrasives. Its mission is to develop and publish standards, documents and comprehensive safety instructions for the abrasive industry. Abrasive grain sizes are produced and sold according to the FEPA standard, among other things. This is to ensure that a consistent quality for

How do i know what abrasive is best for my application?

An abrasive’s shape, hardness, and particle size really determine the effectiveness of a MicroBlasting application. Each application is unique, and abrasive selection depends on the composition of the targeted part and the application’s desired result. See our Abrasive Media Selection Guide to choose the most appropriate abrasive for your application.

Coarseness of the abrasive mineral:

Commonly referred to as “grit”, this number designation is determined by the amount of abrasive mineral that can pass through a mesh screen with specific size openings. Therefore, a 40 grit abrasive particle will pass through a mesh screen that has 40 openings in one linear inch. Consequently, the higher
