Lost Wax Casting Manufacturing

Built for Reliable Industrial Supply

We manufacture and supply standard and made-to-order castings for equipment manufacturers, engineering companies, distributors and industrial projects worldwide.

Our Factory

From Raw Material to Finished Casting

Custom investment castings produced to customer drawings

Our foundry produces investment castings by the lost wax process: valve and pump castings, impellers and rotating parts, brackets and levers, pipe fittings, housings and made-to-drawing precision parts. Production is organized around stable shell chemistry, controlled solidification and dependable heat-to-heat traceability.

Tooling, wax injection, tree assembly, shell building, dewaxing and firing, melting and pouring, cut-off, heat treatment, machining and inspection are coordinated to meet the requirements of each drawing, specification and service condition. Catalog parts and made-to-drawing castings are supplied from roughly 0.02 to 80 kg, in 63 cast grades, at ISO 8062-3 DCTG 5-8 as cast.

01

Casting

Silica sol, water glass and composite ceramic shells, plus vacuum melting for reactive and high-nickel grades. Wax tooling cut in-house from your drawing or 3D model.

02

Alloys

CF8M, CF3M and CA6NM, duplex and super duplex, WCB and low-alloy steel, HK/HP heat-resistant grades, Inconel and Hastelloy, nickel aluminum bronze, aluminum and titanium — chosen against the service, not the price list.

03

Heat Treatment & Machining

Solution annealing, normalizing, quench-and-temper and age hardening, then CNC machining of the faces the drawing calls out. Surfaces not called out are supplied as-cast.

04

Inspection

Spectrometer analysis on every heat, dimensional inspection against the drawing, and hydrostatic, radiographic, dye-penetrant, hardness or dynamic-balance testing as the order specifies.

Inside the plant

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.

  1. Wax pattern being injected into an aluminum die
    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.

  2. Wax patterns assembled onto a runner tree
    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.

  3. Ceramic slurry dipping and stucco coating of a wax tree
    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.

  4. Ceramic shells being dewaxed in a steam autoclave
    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.

  5. Empty ceramic shells entering the firing furnace
    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.

  6. Molten steel being poured into a preheated ceramic shell
    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.

  7. Castings being cut from the runner and ground
    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.

  8. Cast parts being machined and measured against the drawing
    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.

Standards & Custom Parts

Made to the Specification Your Application Requires

We cast to ASTM, ASME, API, EN and ISO specifications, and to customer drawings where no standard applies. When a catalog part does not fit the application, our engineering team reviews the drawing, the 3D model and the service conditions, and comes back with a castability assessment before any tooling is cut.

Material grade, property class, dimensions, tolerances, finish, marking, testing, packaging and documentation can be confirmed before production.
