Raw Materials
- Copper Grade: Most of the high-grade copper is used in the form of C11000 (electrolytic tough pitch copper) in most applications. This grade offers better electrical conductance, corrosional tolerance, and ductility required in production uses as in architectural applications.
- Quality Assurance: We source raw copper through trusted suppliers who test raw material through rigorous testing to ensure that it has desired physical and desired chemical qualities.
Manufacturing process
- Extrusion: Initially, the copper billets are heated to an ideal temperature (generally between 700 to 850°C) to put them in a softer state. They are forced through an appropriately shaped die by an hydraulic or mechanical extruding press. This offers continuous production in regular sectioned special-shape copper extrusions.
- Cooling and Straightening: As an aftermath to the process of extruding, the copper profiles get rapidly cooled to solidify in shape. Following this, they get processed to obtain properly straightened free of appreciable warps or bends.
- Finishing: Depending upon design requirements, these extrusions can go through additional processing steps. This can be anywhere from polishing to achieve shiny finish to anodizing to achieve better corrosion resistance with coloring options to providing protective coats to prevent oxidation.
Quality Assurance
- Dimensional Correctness: Critical dimensional verification during production process is carried out to utmost perfection by equipment such as calipers, micrometers, and Coordinate Measureing Machines (CMMs) to ensure that the extrusions possess desired tolerances in accordance to shape, width, thickness, and length.
- Mechanical Properties: From each production run, samples are drawn to determine mechanical properties such as tensile strength, yield strength, and elongation. Testing is done in accordance with international standards such as ASTM or ISO.
- Surface Quality: Irregularity in the surface in the form of cracks, porosity, or scratches can be brought to the surface by visible inspections and non-destructive testing.
Packaging And Delivery
- Packaging: Special shaped copper extrusions are packed with utmost caution to prevent damage during transit. They are generally placed in wooden crates or steel pallets and cushioned by wrapping in protective film.
- Delivery: Depending upon where customers are situated, products can be delivered by ground, by air, or by water. Delivery is assured to be both in time and secure by partners in logisitics who possess an established performance record.
