How your castings are made
Every part we ship moves through the same eight stages, in our own plant. The controls listed under each stage are the ones that decide whether a casting meets its class — not marketing copy.
-
01 Tooling & wax injection
An aluminum die is cut from your drawing or 3D model, and wax is injected into it under pressure. Everything downstream is a copy of this pattern, so the die is where the tolerance is actually decided — not on the shop floor afterwards.
First-article dimensional report on every new die before production wax is run.
-
02 Tree assembly & gating
Patterns are welded onto a wax runner to form a tree. How they are gated is not cosmetic: the gate positions decide which sections solidify last, and a heavy section fed from the wrong direction is where shrinkage porosity comes from.
Gating reviewed against the part's heaviest section before the first tree is built.
-
03 Ceramic shell building
The tree is dipped in ceramic slurry and stuccoed with refractory grain, six to eight times, drying between coats. The face coat is what the casting surface copies, which is why a silica sol face gives Ra 3.2-6.3 µm where a water-glass shell gives a coarser one.
Slurry viscosity and drying room temperature and humidity logged per coat.
-
04 Dewaxing
A steam autoclave melts the wax out fast, so that the wax — which expands more than the ceramic does — leaves before it can split the shell. Recovered wax is filtered and reused for gating rather than for patterns.
Every shell inspected for cracks after dewax; a cracked shell is scrapped, not patched.
-
05 Shell firing
The empty shell is fired to roughly 1000 °C. Firing burns out wax residue, develops the shell's strength, and preheats the mould so that thin sections fill instead of freezing short of the far end.
Furnace profile recorded per load; shells are poured hot rather than allowed to cool and be reheated.
-
06 Melting & pouring
The charge is induction melted and the composition confirmed on the spectrometer before it is tapped. Reactive and high-nickel grades are melted and poured under vacuum, because poured in air they gas and oxidize, and the inclusions that result are what shortens creep life at temperature.
Spectrometer analysis on every heat, certified against the ordered grade.
-
07 Knock-out, cut-off & finishing
Shell is knocked off, parts are cut from the runner, and gate stubs are ground flush. Heat treatment and blasting follow, in that order — grinding a part after solution treatment puts work back into a surface the treatment was meant to relieve.
Heat treatment to the grade's specification, with furnace charts retained against the heat number.
-
08 Machining & final inspection
Where the drawing calls for machined faces, they are cut from the datums the drawing specifies, not from whichever surface is convenient. Finished parts are then measured against the drawing rather than against the pattern.
Dimensional inspection to the drawing, plus hydrostatic, radiographic, dye-penetrant or balance testing as the order specifies.

About Lost Wax Casting
An investment casting foundry — built around accurate engineering data and fast, honest quotations.
We produce valve and pump castings, impellers and rotating parts, brackets and levers, pipe fittings, housings and made-to-drawing precision castings by the lost wax process. Every product page carries the full parameter table, a technical drawing that redraws to whichever size you select, the alloys the part is legitimately supplied in, and a single-click path to a quotation — so the engineer specifying the part finds what they need without leaving the page.
Our team responds within one business day. A quotation states the alloy, the tolerance grade, the machining scope, the surface finish, the tooling charge and the lead time — the figures that actually decide whether a casting is the right answer, rather than a unit price with the conditions left out.
