Manufacturing Processes and Machinery

Our advanced manufacturing facility employs sophisticated metalworking processes to produce precision sink strainers that meet exacting quality standards. The production sequence begins with material selection and preparation, where premium Stainless Steel sheets are inspected for chemical composition, surface quality, and dimensional accuracy. Deep drawing operations are performed using hydraulic presses ranging from 100-ton to 500-ton capacity, creating the characteristic bowl shape of basket strainers. CNC turret punching machines with multi-tool capabilities create precise perforation patterns, ensuring consistent hole diameter, spacing, and edge quality across all products.

Progressive stamping dies are utilized for high-volume production runs, incorporating multiple forming stages within a single press cycle. Rotary deburring equipment removes sharp edges and burrs from punched holes, enhancing safety and aesthetic appeal. The final polishing process employs vibratory finishing systems with ceramic media and specialized compounds to achieve the desired surface finish. Quality control throughout the manufacturing process includes dimensional verification using coordinate measuring machines (CMM), surface roughness testing, and corrosion resistance evaluation according to ASTM B117 salt spray standards.

Frequently Asked Questions – Stainless Steel Sink Strainers

Q1: What is the difference between 304 and 316 Stainless Steel sink strainers?
A1: 316 Stainless Steel contains molybdenum (2-3%) which provides superior corrosion resistance, especially against chlorides and marine environments. 304 grade is suitable for standard kitchen applications, while 316 is recommended for commercial food service and coastal installations.

Q2: How do I determine the correct sink strainer size for my application?
A2: Measure the sink drain opening diameter and select a strainer with overall diameter 20-30mm larger than the drain opening. Consider the sink depth and available clearance space when selecting basket depth specifications.

Q3: What perforation pattern provides optimal drainage performance?
A3: Round holes with 6-8mm diameter arranged in concentric circles offer the best balance between filtration efficiency and flow rate. Larger holes (10-12mm) maximize flow but reduce particle retention capability.

Q4: Can sink strainers be customized for specific applications?
A4: Yes, we offer comprehensive customization including unique dimensions, special perforation patterns, alternative materials, custom finishes, and application-specific modifications with minimum order quantities starting from 500 pieces.

Q5: What is the expected service life of Stainless Steel sink strainers?
A5: Under normal residential use, quality Stainless Steel sink strainers typically last 10-15 years. Commercial applications may require replacement every 5-8 years depending on usage intensity and maintenance practices.

Q6: How should Stainless Steel sink strainers be cleaned and maintained?
A6: Regular cleaning with warm soapy water and soft brushes prevents buildup. For stubborn deposits, use mild acidic cleaners (vinegar solution) followed by thorough rinsing. Avoid abrasive cleaners that may scratch the surface finish.

Q7: What quality certifications do your sink strainers carry?
A7: Our products comply with ASTM A240, DIN EN 10088, JIS G 4304, and IS 6911 standards. Manufacturing facility is ISO 9001:2015 certified with documented quality management systems and traceability protocols.

Q8: What is the standard lead time for sink strainer orders?
A8: Standard products are typically shipped within 4-6 weeks from order confirmation. Custom designs may require 6-8 weeks depending on complexity. Rush orders can be accommodated with expedited processing fees.

Q9: Do you provide samples for evaluation before placing bulk orders?
A9: Yes, we provide samples of standard products for quality evaluation. Custom sample development is available for qualified customers with specific application requirements and minimum order commitments.

Q10: What packaging options are available for sink strainer shipments?
A10: Standard packaging includes protective plastic bags with corrugated cartons. Custom options include retail blister packs, branded packaging with customer logos, and specialized protective packaging for fragile or high-value products.
