Die CastingFAQ's
Die casting is widely used in Automotive components, Electrical and electronics, Industrial machinery, Consumer appliances, and Engineering equipment. Bombay Metrics supplies precision die cast parts for diverse industries requiring strength, reliability, and dimensional accuracy.
Die casting can achieve tight tolerances, typically within ±0.05 mm to ±0.1 mm (depending on part size and geometry). At Bombay Metrics, strict quality control measures are followed to ensure dimensional consistency and repeatability across production batches.
Die casting capabilities vary depending on machine capacity and tooling design. Components can range from small precision parts to medium-sized structural components. Bombay Metrics supports small to medium-sized die cast components customized as per client drawings and specifications.
Yes. Die cast parts often require additional processing such as CNC machining, Drilling and tapping, Surface finishing, Powder coating, Anodizing, and Plating. Bombay Metrics provides end-to-end solutions including casting, machining, and finishing to deliver ready-to-assemble components.
India is a preferred sourcing destination due to competitive manufacturing costs, skilled engineering workforce, modern production facilities, international quality standards, and strong export infrastructure. Bombay Metrics is a trusted die casting supplier in India serving domestic and global markets with reliable quality and delivery performance.
Compared to sand casting or machining, die casting offers better surface finish, higher dimensional accuracy, faster production cycles, and reduced material waste. Bombay Metrics helps customers choose the most cost-effective manufacturing process based on design, volume, and application requirements.
Quality assurance is critical in die casting. Inspection processes may include Dimensional inspection, Material testing, Surface finish checks, and Batch traceability. Bombay Metrics follows strict quality control procedures to ensure components meet customer specifications and applicable industrial standards.
Lead time depends on Tooling development, Order quantity, Material selection, and Secondary machining requirements. Bombay Metrics works closely with customers to optimize tooling timelines and ensure consistent production schedules.

Yes. Bombay Metrics supports export requirements and supplies precision die cast components to international customers, ensuring quality compliance and timely delivery.
Die casting is a high-pressure metal casting process used to produce precise, complex metal parts in large volumes. Molten metal—typically aluminum, zinc, or magnesium—is injected into a hardened steel mold (called a die) under high pressure. The process allows manufacturers to create parts with tight tolerances, smooth surface finishes, thin walls, and high repeatability. Die casting is ideal for medium to high-volume production where consistency and cost efficiency are critical.
The most common die casting materials include Aluminum (most common for structural components), Zinc (excellent for small, detailed parts), Magnesium (lightweight applications), and Copper alloys (less common, high strength). Material selection depends on strength requirements, weight considerations, corrosion resistance, cost targets, and end-use environment.
Die casting is typically better when production volumes are medium to high, part geometry is complex, and lower per-unit cost is needed at scale. CNC machining is better for low volumes, extremely tight tolerances, and prototyping. For high-volume production, die casting usually offers significantly lower cost per part.
Yes. Die casting is one of the most efficient manufacturing processes for high-volume production. Once tooling is built, the process allows fast cycle times, low per-part cost, consistent quality, and high repeatability. The higher the production volume, the more cost-effective die casting becomes.
Tooling (the steel die) can range from $8,000 to $100,000+ depending on complexity. Tooling cost depends on part size, number of cavities, slides and cores, surface finish requirements, and expected production volume. Tooling is a one-time upfront investment that lowers unit cost over time.
Typical lead times for tooling range from 4 to 12 weeks. Lead time depends on tool complexity, number of cavities, design approval speed, and engineering revisions. An experienced manufacturing partner can help optimize tooling design to reduce delays.
Aluminum die casting offers high strength-to-weight ratio, excellent corrosion resistance, good thermal conductivity, good machinability, and lightweight performance. It is ideal for structural and automotive components where weight reduction is important.
Common defects include Porosity, Cold shuts, Flash, Misruns, and Shrinkage. These can often be minimized through proper tool design, process control, material selection, and secondary finishing operations. Working with an experienced die casting supplier reduces defect risk.
Die casting is better for high-volume production, faster cycle times, and lower per-part cost at scale. Investment casting is better for lower volumes, complex internal geometries, and higher temperature alloys. The right choice depends on volume, material, and tolerance requirements.
Die cast parts can achieve as-cast finish, powder coating, anodizing (for aluminum), painting, plating, and polishing. Surface finish choice depends on aesthetics, corrosion resistance, and functional needs.
Yes. Many die cast parts undergo secondary CNC machining to improve tolerances, add threads, create precision surfaces, and add critical features. Combining die casting with machining improves performance and accuracy.
There is no strict universal minimum, but die casting is typically economical when production runs exceed several thousand units annually. Because of tooling investment, die casting is best suited for medium to high production volumes.
Forged parts generally have higher tensile strength, better grain structure, and greater fatigue resistance. Die cast parts offer excellent dimensional accuracy, lower cost at scale, and faster production. Forging is preferred for high-impact structural components, while die casting is preferred for complex, high-volume parts.
Die casting can improve supply chain stability by reducing part count (consolidated components), improving repeatability, shortening cycle times, and supporting high-volume forecasting. A global manufacturing partner can further reduce supply chain risk through diversified sourcing.
Key design considerations include uniform wall thickness, draft angles for ejection, proper radii, avoiding sharp corners, minimizing undercuts, and designing for manufacturability (DFM) to reduce cost and defects.
Tool life can range from 50,000 to 1,000,000+ shots depending on material used, maintenance, operating temperature, and tool steel quality. Aluminum dies typically last longer than zinc dies.
Die casting can be environmentally efficient because scrap metal is recyclable, production waste is minimal, and aluminum is highly recyclable. Long tool life reduces material waste. Energy usage depends on foundry efficiency and process control.
When selecting a die casting partner, consider engineering support and DFM capability, tooling expertise, quality certifications, secondary machining capabilities, global supply chain management, and industry experience. A strong supplier should provide both manufacturing and supply chain support.
