· Production Process Introduction

1. Design & Perforation Optimization: Our engineering team finalizes perforation size, pitch, and central mounting hole specifications to balance flow rate and filtration efficiency.
2. Material Preparation: Premium stainless steel bar stock is CNC-turned into the cylindrical base and perforated top plate.
3. Precision Perforation: Perforations are created via fiber laser cutting or chemical etching to ensure uniform hole size and positional accuracy.
4. Mirror Polishing & Finishing: Parts undergo multi-stage mechanical polishing to achieve the mirror-bright finish, removing all burrs and surface imperfections, followed by passivation to enhance corrosion resistance.
5. Quality Inspection: 100% dimensional inspection via CMM and flow testing verifies compliance with perforation pattern and performance specifications.
6. Final Packaging: Discs are individually wrapped in anti-scratch PE film, secured in custom foam trays, and packed in reinforced corrugated cartons to protect the mirror finish during transit.

· Packaging and Shipping Methods

• Standard Packaging: Each disc is wrapped in soft anti-scratch PE film, placed in custom-cut EPE foam inserts inside a reinforced corrugated box, with additional cushioning to prevent bending or surface scratching.
• Shipping Options:
  • Express Delivery (3–7 Business Days): DHL/FedEx/UPS for prototype and small-batch orders (full tracking provided).
  • Standard Sea Freight (25–40 Business Days): Cost-effective FCL/LCL options for large-volume production orders, with full customs documentation support.
• Custom Packaging: Branded labeling, barcoding, serialized part marking, and sterile packaging (for medical/pharmaceutical use) are available to align with industry-specific requirements.

· Frequently Asked Questions (FAQ)

What is your Minimum Order Quantity (MOQ)?

What are your typical lead times?

• Prototype/Sample Orders: 7–12 business days from final CAD design approval (includes fabrication and mirror polishing).
• Mass Production: 15–25 business days, depending on order volume, perforation complexity, and surface finish requirements.
• Rush Service: Expedited production (4–7 days for prototypes) is available upon request for urgent projects.

Can you accommodate full custom modifications?

• Material Customization: 316L stainless steel for high-corrosion environments, or 304 stainless steel for general industrial use.
• Design Modifications: Custom perforation size/pitch, central mounting hole diameter, and overall disc dimensions to match your filtration/ventilation needs.
• Surface Finish Options: Alternative finishes (brushed, bead blasted, or electropolished) for specific performance or aesthetic needs.
• Branding & Traceability: Laser engraving of part numbers, batch codes, or logos for full product traceability and inventory management.
