An investment casting foundry built around engineering data and fast, accurate quotations.
Near-net shape
Thin walls, cored passages and cast blade profiles that a machined or fabricated part cannot hold — ISO 8062-3 DCTG 5-8 as cast, at Ra 3.2-6.3 µm.
63 cast alloys
CF8M, CF3M, CA6NM, duplex and super duplex, WCB and low-alloy steel, HK/HP heat-resistant grades, Inconel and Hastelloy, nickel aluminum bronze, aluminum and titanium.

How your castings are made
Every part we ship moves through the same six 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 Assembly
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 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 & firing
Steam autoclave melts the wax out — fast, so the shell does not crack as the wax expands — and the empty shell is then fired to around 1000 °C. Firing burns out residue and preheats the mould so thin sections fill instead of freezing short.
Shells inspected for cracks after dewax; any cracked shell is scrapped, not patched.
-
05 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.
-
06 Finishing & inspection
Shell is knocked off, parts are cut from the runner, gates are ground flush, and the castings are heat treated, blasted and — where the drawing calls for it — machined. Then they are 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.
Free Engineering Calculators
Bench-side tools for casting work — pour weight, shrinkage allowance, machining stock, minimum wall thickness, riser sizing and alloy density. Open any tool below.
Pour Weight
Part volume × alloy density → casting weight, plus gates and risers.
Shrinkage Allowance
Pattern size from finished size, by alloy solidification shrinkage.
Machining Allowance
Stock to add per face, by casting size and tolerance grade.
Minimum Wall Thickness
Smallest section this shell will fill, by alloy and flow length.
ISO 8062-3 Tolerance
Tolerance band for a dimension at a given DCTG grade.
Alloy Density
Density and typical mechanical properties for 63 cast grades.
Metric ↔ Imperial
Length, mass, force and pressure converter.
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.
