How much of the metal you pour actually becomes your part?

In investment casting, not all poured metal ends up in the final component.
A certain amount solidifies in the gating and runner system. It is essential for controlled mold filling and feeding, but it is also one of the main areas where metal yield can be improved.
At Plasmaterm, metal yield is an important process metric. We track the ratio between the finished part weight and the total poured weight and continuously look for ways to improve it.
Gating system design plays a major role here. By optimizing runner geometry and using solidification and feeding analysis, we work to reduce the amount of metal tied up outside the casting — without compromising filling quality or creating shrinkage defects.
It is not just about simulation. The best results come from combining engineering analysis with practical process experience built up through years of production.

The goal is straightforward:
Higher material efficiency.
Lower melt consumption per part.
A more cost-effective casting process.

All while maintaining the dimensional and internal quality our customers expect.

Tunnel kiln thermal profile — the burnout curve as a quality parameter

In investment casting, the ceramic shell enters the tunnel kiln carrying wax, binder residues, and internal stresses. What comes out the other end determines whether the mold is ready to cast — or not.
The burnout curve controls how this transition happens. Heat too fast, and internal v***r pressure builds before the wax has a path to escape — the result is cracking, distortion, or shell failure before the mold ever sees metal. Heat too slowly or insufficiently, and residual organic material remains inside the cavity, directly contaminating the casting surface and chemistry.
The thermal profile must be matched to the specific ceramic shell system in use. Each heating zone in the tunnel kiln serves a defined purpose: controlled wax liquefaction and drainage, binder decomposition, and final ceramic consolidation. These stages overlap in temperature but must not compete in timing.
Correct burnout does more than remove the pattern. It completes the sintering of the ceramic structure, improving shell strength and dimensional stability at pouring temperature.
At Plasmaterm, the burnout curve is treated as a fixed process parameter — not a default setting. Zone temperatures and belt speed are calibrated to our shell system, and stability of the profile is monitored as a direct quality input.
A clean, crack-free, fully burned-out shell is the baseline. Everything downstream depends on it.

A few degrees can be the difference between a perfect casting and a rejected one.

Ceramic shell temperature at the moment of pouring is one of the most consequential variables in investment casting. It is set before the metal moves—and its effect runs through fill behavior, solidification, microstructure, and final part quality.
The principle is straightforward: a cold shell extracts heat from the incoming melt faster than the geometry allows for complete filling. The result is premature solidification at the mold wall, leading to misruns, cold shuts, and surface defects. A properly preheated shell eliminates this thermal mismatch and creates stable, predictable filling conditions.
Beyond filling, shell temperature directly influences the solidification rate and thermal gradient—both of which determine grain structure and the mechanical properties of the finished casting. Uneven or insufficient preheating introduces process variability that is difficult to eliminate later.
At Plasmaterm, shell preheat is treated as a critical process parameter, not simply a preparatory step. Temperature is continuously monitored and controlled to ensure uniformity across every ceramic shell before pouring. This level of process control is what makes quality and yield repeatable.
Consistent process control starts long before the metal is poured—and it is reflected in every finished casting.

Alloy transitions in investment casting — where calculation meets craftsmanship

In foundry operations, alloy changes are never simply a material swap. They are a controlled metallurgical process that demands both engineering precision and accumulated process knowledge.
At Plasmaterm, our induction melting furnace retains approximately 20 kg of residual melt after each heat. This heel is not an inconvenience — it is a variable we systematically account for in every charge calculation.
When transitioning between alloy grades, the residual composition is fully incorporated into the target chemistry calculation. Correction factors are applied before any new charge material is added, ensuring the final melt meets specification without deviation.
For us, this is standard practice, not an exception. Our team manages alloy transitions through structured charge calculations backed by decades of hands-on foundry experience, delivering predictable and reproducible chemistry from heat to heat.
Controlled heel management is one of the less visible but genuinely differentiating aspects of precision investment casting. It reflects the level of process discipline that separates reliable suppliers from the rest.

Why salt bath nitriding still in use?

It has served the industry well for decades—but manufacturing priorities have changed.
Salt bath nitriding requires cyanide-based salts, operates at higher temperatures (typically 570–590°C), and involves hazardous waste treatment.

Plasma nitriding offers a cleaner alternative:

✔ Lower process temperatures (480–530°C)
✔ Better dimensional stability
✔ Precise, repeatable results
✔ No cyanide salt waste

The question isn't whether salt bath nitriding works.
The question is whether it's still the right choice for modern manufacturing.

The Romanian pavilion at CastForge 2026 had unexpected visitors.

Mr. Cristian Ovidiu Mateescu, Trade & Investment Promotion Counsellor at the Romanian Agency for Investment and Foreign Trade, and Ms. Clara Suzana Râpan, Vice Consul of Romania in Germany, stopped by the stand — a signal that Romanian precision manufacturing is being taken seriously at the European sourcing level.
The conversation wasn't about politics. It was about what Romanian suppliers can actually deliver: certified processes, full traceability, and integrated capabilities that reduce supplier chain complexity for Western European OEMs.

That's the direction the market is moving.

Most steel housings with internal channels are still machined from billet.
Not because casting can't produce them. Because the question wasn't asked at the right stage.
A billet starts at 2.8 kg. The finished part weighs 0.9 kg. That's 1.9 kg of material removed — on a CNC, hour by hour, operation by operation.
Investment casting produces the same part near-net-shape: internal channels, undercuts, and wall transitions directly in the cast. Secondary machining is limited to functional interfaces. Accuracy: VDG P690 D1/D2.
The geometry doesn't change. The manufacturing route does.
This is the conversation we want to have at CastForge 2026.
Bring your most complex drawing to CastForge 2026 — 8D33.
We assess feasibility on-site. No pitch. Just the engineering.

And if you're not attending, this is exactly why trade fairs like CastForge exist. Not to see brochures. To sit across from the engineer who runs the process and ask the question you've been carrying since the last failed RFQ.
CastForge brings the whole supply chain into one hall for two days. Use it.

09/06/2026

CastForge 2026 has officially opened its doors in Stuttgart.

We're at the Romanian National Pavilion this week — and if you work on complex steel components, precision tolerances, or integrated casting and surface treatment, we'd like to compare notes.
The team is there to talk about the process.

If you're working on sourcing challenges or component qualification, find us there.
