Sumer Metal Industries Private Limited manufactures precision Stainless Steel 304 / 304L needle tubes engineered for industries that demand corrosion resistance, biocompatibility and dimensional accuracy. Using tightly controlled cold-drawing and annealing processes, Sumer produces bright, smooth-walled tubes suitable for medical devices, pharmaceutical instrumentation, food processing, instrumentation, and fine mechanical assemblies. Their production line focuses on consistent concentricity, minimum ovality and strict surface finish tolerances to meet needle- and capillary-grade requirements.
As a manufacturer, supplier and exporter, Sumer Metal Industries ships 304/304L needle tubes worldwide — notably to Oman, Qatar, Saudi Arabia, the UAE, Kuwait, Spain, Germany, the USA, Canada and multiple African markets. Their export process includes export-grade protective packaging, certificate-of-origin documentation, and compliance packaging for long-sea and air shipments to protect internal finishes and prevent contamination during transport.
Sumer emphasizes quality assurance: material certification (mill test certificates to ASTM/EN standards), dimensional inspection reports, surface finish checks (Ra where required), and traceability from melt to finished tube. Typical quality standards referenced are ASTM A269 / A213 / A312 (where applicable to tubing forms), ISO 9001 quality systems, and customer-specific audits. They also offer additional testing (passivation, electropolish, hydrostatic/leak tests) on request.
Applications and value-adds: 304 is the workhorse austenitic grade offering excellent formability and corrosion resistance; 304L (low carbon) reduces carbide precipitation during welding and is preferred where post-weld corrosion resistance is critical. Sumer supplies tubes for hypodermic needle assemblies, catheter shafts, lab instruments, fuel injection components, and high-purity fluid lines. They can supply annealed, bright-drawn, cold-worked or electropolished finishes depending on application needs.

Customization & sizes: Sumer produces a wide dimensional range with controlled wall thickness and inner-diameter tolerance for needle-precision use. Options include tight tolerance concentricity grades, special cut-to-length, chamfering, deburring, and cleaning (ultrasonic, solvent, passivation) prior to packing. They support small minimum order quantities for prototype runs and scale to large production lots for OEMs.
