Hiren Brass Products is a supplier of different types of casting components. We can accommodate a wide range of sizes and complex configurations. Our ISO 9001 certification is a testament to our company-wide commitment to the quality our customers have come to expect.
Types of Casting Processes
Also known as a lost wax casting, investment casting is an advanced metal forming process commonly applied in cases where both solid parts and complex, hollow cores are required. We create high-quality metal parts using disposable patterns that are exceptionally functional and cost-effective.
In the investment casting process, wax is injected into a metal die to produce a pattern. This pattern is a replica of the part to be produced. The castings are then coated in ceramic, dewaxed or hollowed out, and heated to a high temperature – which depends on the metal or alloy used for the castings. The hot alloy or metal is then poured into the hot cast shell. Any remaining ceramic is blasted from the metal parts and scrapped. Our testing capabilities include a full chemical, physical and nondestructive.
A process typically relying on silica-based materials, sand castings process involves finely ground, spherical grains tightly packed together into a smooth molding surface. It is a cost-effective process that can be produced both large and small parts.
In sand casting, a wooden or metal pattern is used in conjunction with a sand core box to machine cast parts and components. Molten metal alloys are poured into a sand cast mold to form the component. The sand is removed after the metal has cooled and the metal is then blasted or surface treated in some way to finish the machining process.
Die casting involves the molding of materials under high pressure, and consists of a cold chamber, hot chamber and multi-slide hot chamber casting. Hot chamber die casting is generally used for an assortment of magnesium alloys, zinc and any other alloys with lower melting points. Cold chamber die casting is used for metals with a higher melting point, namely aluminum.
The three alloys primarily used in die casting are aluminum, zinc, and magnesium. These allow all possess strong corrosion resistance, high strength and hardness, high thermal and electrical conductivity, and incredible EMI/RFI shielding properties.
There are several benefits to die casting services, namely that they allow for the creation of complex shapes such as external threads. This can help to minimize secondary operations and can lower production costs. Die casting also provides:
- Improved production speed due to fewer steps from material to finished product
- Reduced scrap metal
- Tight tolerances
- Variable wall thickness
- mprove product life
- Improved surface finish and stability
Permanent Mold Casting
Permanent mold casting is a process used in which permanent or reusable molds consists of mold cavities, machined into metal die blocks and appropriate for repetitive use. These molds help to shape the liquid casting metals into the desired part or component.
Permanent mold casting services help to maintain overall dimensional stability. Allowances for machining, however, are smaller due to the finished casting being much closer to the final specification. This process creates castings that are denser, tighter and stronger, requiring less finishing and surface treatment.
Plaster casting is a casting process with similarities to sand casting. Instead of using sand in the process, a mixture of water, gypsum and strengthening compounds are used.
