Casting, Waxing & Investment Materials
Casting, waxing and investment materials for the dental lab lost-wax workflow - inlay wax, baseplate wax, sprue and casting wax, phosphate-bonded and gypsum-bonded investments, casting rings, ring liners and crucibles from Whip Mix, Kerr, GC, Bego and Renfert. Consumables for crown, bridge and partial-denture framework casting in commercial and in-house labs. Waxes and investments are short-cycle consumables stocked in sticks, sheets and pre-weighed pouches that reorder against production volume, which keeps material lots consistent across a lab's casework. Wholesale case pricing for dental laboratories and institutional procurement.

Casting, Waxing and Investment Materials for Lost-Wax Fabrication
Casting, waxing and investment materials are the consumables that carry a restoration through the lost-wax casting process, from wax pattern to cast framework. The category serves commercial dental labs, prosthodontic practices, dental schools and hospital in-house labs producing crown, bridge and partial-denture castings.
Casting and Investment Consumables Stocked
- Inlay and pattern waxes - Hard, medium and soft inlay waxes for direct and indirect wax patterns, stocked in stick, sheet and blue and green pattern forms.
- Baseplate and modeling waxes - Pink baseplate wax and modeling waxes for denture setups, bite rims and record bases, in standard sheet formats.
- Sprue and casting wax - Round and rectangular sprue wax, wax wire and casting bars for building sprue systems and connectors on wax patterns.
- Phosphate-bonded investment - High-heat investment for casting high-fusing alloys and for pressed-ceramic workflows, sold in pre-weighed pouches and bulk.
- Gypsum-bonded investment - Investment for casting gold and lower-fusing alloys in crown, bridge and inlay work.
- Casting rings, liners and crucibles - Metal and silicone casting rings, ceramic ring liners and replacement crucibles for centrifugal and induction casting machines.
Investment and Wax Formats
| Material | Workflow Role | Common Formats |
|---|---|---|
| Inlay / pattern wax | Building the wax pattern | Sticks, sheets, pellets |
| Sprue wax | Sprue and connector formation | Round and rectangular gauges |
| Baseplate wax | Denture setups and record bases | Sheet boxes |
| Phosphate investment | High-fusing alloy and pressed ceramic | Pre-weighed pouches, bulk |
| Gypsum investment | Gold and low-fusing alloy casting | Pre-weighed pouches, bulk |
The Lost-Wax Casting Sequence
These consumables move a case through the lost-wax process in order: a wax pattern is built in inlay or pattern wax, sprued with sprue wax, invested in a casting ring with phosphate- or gypsum-bonded investment, burned out to eliminate the wax, and cast with molten alloy. Investment selection follows the alloy and the burnout temperature, and ring liners control investment expansion. The category groups every wax and investment product used across this sequence.
Casting, waxing and investment materials are short-cycle consumables that labs reorder against production volume, which makes lot consistency and case pricing central to a lab's material budget. Phosphate investments and pattern waxes are among the most frequently automated laboratory reorders. Order at the best Wholesale Prices with MAP Medical.

These consumables are cast, mixed and burned out on the hardware stocked under lab equipment, machinery and tooling. Finished frameworks carry the removable prosthetic work covered in denture and prosthetic materials, while digital labs press and mill from designs built in digital design and fabrication software.

Frequently Asked Questions
What is the difference between phosphate-bonded and gypsum-bonded investment?
Phosphate-bonded investment withstands the high burnout and casting temperatures used for base-metal and high-fusing alloys and for pressed-ceramic workflows. Gypsum-bonded investment is used at lower temperatures for casting gold and lower-fusing alloys. The alloy and the burnout temperature determine which investment a lab selects, and most labs stock both.
What waxes are used in the casting workflow?
The workflow uses inlay and pattern waxes to build the pattern, sprue wax to form the sprue and connector system, and baseplate and modeling waxes for denture setups and record bases. Inlay waxes are stocked in hard, medium and soft grades, and sprue wax is stocked in several round and rectangular gauges.
What casting ring and crucible formats are stocked?
The catalog stocks metal and silicone casting rings in standard sizes, ceramic ring liners that control investment expansion, and replacement crucibles for centrifugal and induction casting machines. Ring and crucible sizing follows the casting machine and the volume of the ring being invested.
Can dental labs order casting and investment materials in bulk?
Yes. Waxes, phosphate- and gypsum-bonded investments, casting rings and crucibles are stocked in case quantities for commercial labs, dental schools, hospital in-house labs and licensed distributors. Standing order programs cover high-velocity consumables such as pattern wax and phosphate investment. Contact our procurement team for tiered case pricing and standing order setup.
What casting and investment products should be in a lab formulary?
A core casting formulary typically includes a hard and a soft inlay wax, sprue wax in two gauges, pink baseplate wax, a phosphate-bonded investment for high-fusing and pressed work, a gypsum-bonded investment for gold casting, and a stock of casting rings, liners and crucibles matched to the lab's casting machine.
