Hi-WiLL manufactures investment (lost-wax) castings in stainless steel and WPS grades — from a single prototype to running production — engineered in-house from pattern development through to final machining and inspection.
Complex geometry, thin walls, and near-net-shape accuracy, produced under an ISO 9001:2015 quality system, in the same 43,750 sq ft facility as our machining and QC lab.
Every casting starts life as a wax pattern on a tree — the same process that gives investment casting its name.
Hi-WiLL’s investment casting division produces stainless steel and WPS components using the lost-wax process — built for customers who need complex geometry, thin walls, or an as-cast surface finish that other casting methods can’t deliver.
Because our die and pattern making division, foundry, CNC machine shop, and quality lab all sit inside the same facility, a casting doesn’t have to leave the building to be machined, heat treated, or inspected. One team is accountable for your component from wax injection to final dispatch — not three separate vendors passing the part between them.
0.05–50 kg
Per-Piece Weight Range
SS304 / SS316 / WPS
Core Material Grades
Internal passages, thin walls, and intricate details that would need extra tooling or machining in other processes.
Single-piece prototype trees for a new design, or repeat production runs on an approved pattern — same quality system either way.
Castings move directly into our CNC shop and QC lab — no shipping a part out for finishing and waiting for it to come back.
An austenitic stainless grade valued for its corrosion resistance and weldability — a common default for general industrial and food/pharma-adjacent components.
Molybdenum-alloyed for superior resistance to chlorides and harsher chemical environments — specified where SS304 isn’t corrosion-resistant enough.
Our working-pattern-steel castings, specified for components where a harder, wear-resistant grade is called for over standard stainless.
Working in a different alloy? Our team also machines carbon steel, alloy steel (EN8/EN19/EN24), and non-ferrous metals elsewhere in our facility — send us your specification and we’ll confirm whether it’s a fit for investment casting.
Molten wax injected into a precision die to form an exact replica of the finished part, including any internal detail.
Multiple wax patterns joined to a central sprue to form a "tree" — allowing several parts to be cast in a single pour.
The tree is dipped in ceramic slurry and stuccoed in repeated cycles, building a rigid shell mould around the wax.
The shell is heated so the wax melts and drains out, leaving a hollow ceramic mould — the "lost wax" step the process is named for.
Molten SS304, SS316, or WPS alloy poured into the preheated shell under controlled temperature and timing.
The ceramic shell is broken away and each casting is cut from the tree, ready for finishing.
Gates and risers removed, surfaces ground and finished, with heat treatment applied where the specification calls for it.
Dimensional verification, spectrometric composition checks, and radiography/ultrasonic testing where specified, before dispatch.
Our investment casting facility sits inside the same 43,750 sq ft campus as our machine shop, die and pattern making division, and quality lab — on the Rajkot–Gondal Highway, Gujarat. Wax injection, shell building, dewaxing, melting, fettling, and inspection all happen under one roof, with no handoff to an outside vendor at any stage.
Patterns and dies for new investment casting projects are developed by our in-house tooling division — the same team responsible for our plastic moulding, die casting, and pattern-making capability — so a new part doesn’t need a separate tooling supplier before it can go into casting.
