Metal casting process
Overview

What is Metal Casting?

Metal casting is a versatile manufacturing process that shapes complex, high-strength metal parts by pouring molten metal into a precisely engineered mold. It excels at producing components with intricate geometries, internal cavities, and mechanical properties that are impractical to achieve through machining or fabrication alone.

At SHBD Metal, our online casting service is built for reliability. We address the classic casting challenges — porosity, shrinkage, dimensional drift, and inconsistent material properties — through sand, investment, and die casting capabilities supported by simulation-driven process optimization and strict quality protocols. The result is castings with structural integrity, consistent performance, and assembly-ready fit.

Streamline your supply chain with our digital workflow: upload your 3D model, receive an instant detailed quote and a comprehensive manufacturability review, and move into high-integrity cast production through a process defined by precision, transparency, and on-time delivery.

FAQs

Metal Casting FAQs

Defects are prevented at the design and process level: DFM analysis optimizes gating and riser design, controlled pouring and solidification profiles minimize shrinkage, and degassing plus melt filtration reduce gas porosity. Every batch is verified through X-ray and ultrasonic inspection so defects are caught before parts ship.
Depending on the process, we achieve CT4-CT6 accuracy in high-pressure die casting and vacuum casting, and CT4-CT5 in investment casting. Post-casting CNC machining can tighten critical features to ±0.025mm where required, with CMM verification on every critical dimension.
Yes — we have no MOQ. Prototypes and low-volume batches (from 1 to 1,000 pieces) can run through vacuum casting, sand casting, or soft tooling, letting you validate design and fit before committing to high-volume production tooling.
Material certification starts with spectrometer analysis of the melt chemistry, followed by tensile, hardness, and impact testing on test bars cast from the same heat. Heat treatment cycles are logged and validated, and full material reports accompany every shipment.
Yes. High-pressure die casting handles wall thicknesses from 1.5mm with intricate internal features thanks to precise core and slide design. Investment casting extends this to very complex geometries including internal channels, while vacuum casting supports thin walls with minimal porosity.
Every part is traceable to its heat, batch, and process records. Documentation includes material certificates, dimensional inspection reports, NDT reports, heat treatment logs, and certificates of conformance. Custom PPAP and IATF 16949-aligned documentation packages are available.
For soft-tooled or pattern-based processes, first samples typically ship in 10-15 business days. Production hard tooling requires 3-5 weeks depending on cavity count and complexity, with bridge production available to cover the gap while tooling is completed.
We operate an IATF 16949-aligned quality system built on our ISO 9001:2015 certification, with ISO 13485-aligned processes for medical components. Full traceability, PPAP documentation, and material certification support automotive, aerospace, and medical compliance requirements.
Key levers: uniform wall thickness, generous draft angles, minimized undercuts, standard alloys, and multi-cavity tooling for high volumes. Our DFM review flags cost drivers before tooling and recommends geometry adjustments that lower unit price without compromising function.
Absolutely. We handle casting, post-casting CNC machining, heat treatment, surface finishing, assembly, and packaging in-house — delivering ready-to-install components from a single supplier with one point of accountability for quality and schedule.
