Our Machined Investment Casting Process
The following machining process ensures every machined investment casting achieves dimensional accuracy, repeatability, and superior surface finish before shipment.
Casting tree break-out and initial separation
- Extracting the 'as-cast' components from the ceramic casts via knocking.
- Visual inspection for misruns and irregularities.
- Defective pieces sent for rework or scrapped.
Extracting individual components
- Abrasive cut-off wheels or band saws cut away the gate, leaving a stub behind.
- Air blasting or using coolant to control heat and remove chippings.
- Deburring gate stubs and sharp edges.
Fettling and gate grinding
- Using pedestal and portable angle grinders to ground down gate stubs and runner fragments.
- Using belt grinders to smooth out parting line flash.
- Parts are cleaned to remove dust, scales, and debris, and deliver a fettled blank.
Planning machining allowance and setup
- Identifying and marking critical and non-critical surfaces.
- Outlining the gamut of machining operations.
- Finalizing fixtures to minimize local distortions during operations.
Primary machining operations (roughing)
- Loading the fettled blank into the required machining center.
- Rough facing for rotational parts, rough milling for complex parts, and rough drilling holes.
- In-process inspection to catch gross errors early.
Secondary machining operations (finishing)
- Final passes and milling critical flat surfaces and mating faces to achieve required dimensional tolerance and surface finish.
- Drilling rough bores to final size and tolerance, followed by precision threading.
- Broaching, honing, and other special operations as per requirement.

How to Choose the Right Machined Investment Casting Exporter
Choosing the right machined investment casting exporter is critical for ensuring consistent quality, on-time delivery, and long-term manufacturing success. Whether you source components domestically or internationally, evaluating technical capabilities, quality certifications, machining expertise, and export experience helps reduce project risks and total cost of ownership. Consider the following factors before selecting your manufacturing partner.
- Filter by ISO 9001:2015 certification: This is the bare minimum for a foundry that promises adequate production management and quality control.
- Narrow down by PED 2014/68/EU and AD 2000 Merkblatt W0 certification: These are necessary for any machined investment castings manufacturer exporting to the EU and serving the German market.
- Evaluate based on process transparency: Is the foundry you are considering upfront about how they undertake machining and the internal benchmarks they have? Clarity at this stage can significantly lower total cost of ownership in the long run.
- Look into their packaging options: Do they use freight-worthy packaging? Do they cover edges with rubber covers? Do they provide adequate padding? Are they aware of local waste/transport rules?
- Validate sector-specific experience and performance: Enquire into their track record for on-time delivery, experience with sector-specific alloys, and tolerance requirements. A foundry with experience in your sector can significantly de-risk your project.
FAQs
Is Vimax Technocast only a machined investment casting exporter?
No, we are an investment casting foundry that manufactures, finishes castings in-house, and exports them globally. We are not just a stockist or exporter of finished components.
What incoterms do you work with?
We work with most incoterms—from EXW to DAP. However, the incoterms are subject to order quantities and destination. For an incoterm tailored to your project requirements, please request a quote.
What materials can your machine for a proper finish?
We can machine every material that we pour with. If not, we have a robust partner network to handle the same. You get the results you desire without any additional responsibility whatsoever.
Are all metals suitable for machining?
Most metals are suitable for machining, except those that are gummy or brittle. Examples include tin and very soft tin alloys, lead and lead alloys, and gold alloys with a high degree of gold.
Share your drawings, material specifications, and compliance requirements. We’ll evaluate your application and provide a detailed quotation along with manufacturing recommendations.
