About Us

Smart Tech Metal has patronized with many brands of the world with its manufacturing for Brass, Copper and Bronze – PRESSURE DIE CASTING COMPONENTS , based at Brass Hub of World, Jamnagar, India Please find given below benefit of brass pressure die casting, our company’s profile and recent achievement for QUALITY and EXCELLENCE in this mail related to BRASS, COPPER AND BRONZE CASTINGS COMPONENTS.We deal with lots of OEM’s companies across India. Initially for the ball rolling send us your drawing and specification in order to enable us to quote. As soon as we will get the specifications we will provide you samples for your approval. We offer high temperature die-castings using brass casting alloys. Sizes ranging from less than 100 gm to 1.5 kg are available. Features of brass castings: Corrosion, abrasion, wears resistance, temperature resistance, and electrical conductivity. Applications of brass casting: electric motor components, architectural hardware, decorative hardware, locks and door handles, enclosures, fluid metering, control equipment, plumbing hardware, lighting fixtures, fire protection devices, bearing sheaves. The appilcable ASTM standard for copper casting is ASTM B176-04. Suitable Copper Materials are Copper-Zinc Alloy: C85700, C85800, C86500, C87800 - Typically 55-60% copper, 30-40% Zinc. Copper-Zinc-Manganese Alloy: C99700 and C99750 - Typically 55-60% copper, 20% Zinc, 11 - 23% Manganese Some copper pieces might be better forged than die casted. When in doubt, please consult with our engineering staff.
Benefits of Die Casting :
Long Tool Life - 100000 - 200000 parts of identical die castings can be produced from a die tooling. Speed of Production - Die asting process is highly automated. Multi-cavity dies can also be used to speed up.

Good Finish: Die cast parts can be manufactured with smooth or textured surfaces, and are easily plated or powder coated. EMI, RFI Shielding and can also act as an electrical ground for circuits.

Dimensional Precision: Dimensional tolerances are controlled by mold, thus high repeatability than machining. Cost Savings - Efficient, economical process for high volume production.

Strength: Produces heat and wear resistant parts.
Die Casting Versus other Manufacturing Techniques:
vs. Machining - Die castings produces shapes that are difficult to make from bar or tubular stock. Die castings also require fewer operations and reduce material scrap. For mass production, it results in cheaper unit price. However, die casting surface is not as smooth/ shiny as machined surface, and die casting is usually only economical when order quantity is above 1000 units.
vs. forgings - Die castings produce more complex shapes than forging and die casting is more precise than forging. It also results in thinner walls, which means lighter weight, more space and less material cost. However, die casting is not as strong as forging. Material is also not as dense after die casting.
vs. sand castings and permanent mold casting: Die castings results in closer dimensional tolerances and smoother surfaces. Production is faster and finishing costs are also less. But die casting can only work with thin wall applications and die casting mold is pricier.
vs. stamping - Die casting produces more complex shapes and with variations possible in section thickness. One die casting part may replace several stamping parts and resulting in reduced assembly time and continuous/ leak-free surface. However, stamping mold is cheaper and stamping is a faster process, and die casting walls are thicker than stamping.
