Supplier typeThe supplier is classified as a combined company and its stated business scope includes manufacturing, sales, mold production, equipment, metal products, special ceramics, composite materials, and technical services. This supports a diversified manufacturing-and-trading profile rather than a narrowly defined sales-only supplier.

After-Sales capabilityThe supplier has clear procedures and followed records for corrective and preventive actions and customer complaints, plus written procedures and records for assessing service capability. However, it reports no overseas warehouse, showroom, agent, branch, or offline trade-show participation, and lists zero countries for overseas services, indicating documented service processes but limited overseas service infrastructure.

R&D capabilityThe supplier reports new products during the past year, ODM services, available SDK capability, and research and development activities related to new material technologies and equipment. These details provide explicit evidence of active innovation and development capability.

Production capacityProduction evidence includes a machining-equipment facility, five quality assurance and quality control inspectors, uniformly followed finished-product inspection instructions, valid manufacturing contracts with associated subcontractors, inventory capability, and stated lead times within 15 working days in both peak and off seasons. The supplier also reports top-level quality-control capability for its own-brand products, supporting a positive production assessment.

Customization capabilityThe supplier explicitly offers customization from samples, customization from designs, full customization, minor customization, and flexible customization. These options are reported consistently across the research and development and design-capability information, demonstrating broad customization coverage.

Client casesOne buyer name, GRASIM INDUSTRIES LTD, is associated with the supplier, and the listed product is a Stellite SP1153 blade for a viscose staple fiber plant cutter. This provides one identifiable customer-product association, but the slices do not establish order volume, delivery performance, repeat business, or independently verified case outcomes.

Product Q&A

Q:Why choose ST 20 over ST 6 for can seaming rolls?

While ST6 is the most common cobalt alloy, ST 20 contains a higher percentage of Tungsten and Carbon, creating a denser concentration of hard carbides. In high-speed canning lines, ST 20 offers superior resistance to abrasive wear, maintaining a sharper groove profile for significantly longer periods, which reduces the frequency of seam adjustments.

Q:What level of dimensional precision can you guarantee for custom profiles?

We understand that seam integrity depends on accuracy. Our CNC grinding facilities can maintain tolerances to meet your specific requirements. Every batch undergoes rigorous inspection using coordinate measuring machines (CMM) to ensure the seaming curve perfectly matches your technical drawings.

Q:Can ST 20 rollers withstand harsh CIP (Clean-in-Place) environments?

Yes. ST 20 is a cobalt-chromium-based alloy with exceptional chemical stability. It is highly resistant to the organic acids found in foods (such as tomatoes or citrus) and the aggressive alkaline cleaners used in CIP sterilization cycles. It will not rust or undergo intergranular corrosion, ensuring food-grade safety and hygiene.

Q:What quality certification do you provide for material traceability?

We provide a comprehensive quality package with every shipment, including: Material Certificate (Spectrographic Analysis) confirming Co, Cr, and W content. Hardness Testing Report (HRC). Dimensional Inspection Report (for custom profiles). Full batch traceability from raw material to finished product.
