Manufacturing Process FAQs

For large-scale orders, Samsink employs a hydraulic drawing process using custom molds. This method is ideal for standardized single or double basin sinks and supports high-volume production (up to 100,000 units per month).Material: 304/316 grade stainless steel (0.8–1.2mm thickness)Process: Laser cutting → multi-stage drawing (800–1200 tons pressure) → trimming → welding → surface finishingAdvantages: High precision (±0.5mm), low waste, fast turnaround (1–2 days per batch)This process is recommended for buyers with annual volumes exceeding 10,000 units.

Yes. Samsink specializes in handmade, mold-free manufacturing for non-standard or complex sink designs, such as irregular shapes, integrated countertops, or commercial kitchen equipment.Process: CAD design → laser cutting → CNC bending → laser/argon arc welding → hand grinding → surface treatmentMinimum Order Quantity (MOQ): 5 piecesLead Time: 7–10 days per batchAdvantages: Unlimited design flexibility, high-end finish, ideal for boutique hotels, labs, and medical facilitiesWe also offer sample services (cost deductible from order) and full IP protection.

Samsink uses only high-quality 304 and 316 grade stainless steel (0.8–3.0mm thickness) for all sinks.Material Verification:Mill Test Certificates (MTC) for every batchHandheld PMI (Positive Material Identification) spectrometers for on-site grade confirmationStandards Compliant: ASTM A240, ISO 9001, NSF/ANSI 51316 grade is recommended for high-corrosion environments (e.g., coastal areas, labs, food processing).

Samsink ensures dimensional accuracy through:Laser cutting with ±0.1mm precisionCNC press brakes with ±0.5° bending angle controlIn-process inspection using CAD-guided measurement systemsFinal 3D scanning for full geometry validationAll critical dimensions are held within ±0.5mm tolerance, meeting global installation standards.

Samsink provides a range of premium surface finishes:Brushed (Hairline): Durable, scratch-resistant, modern lookMirror Polish: High-gloss, elegant finishTextured/Non-Slip: Ideal for commercial useOptional Coatings:Antibacterial PVD coating (ideal for medical, food service)Fingerprint-resistant nano coating (reduces smudges and maintenance)Surface roughness is controlled to Ra 0.4–0.8 μm for consistent quality.

For new mold development, the typical timeline is:Design & Engineering: 1–2 weeksMold Manufacturing: 3–5 weeksSample Production & Approval: 1–2 weeksTotal: 4–8 weeksOnce approved, production batches can be completed in 1–2 days, with flexible delivery options (4–6 weeks for standard orders).
