Frequently Asked Questions
- What materials are available for the perforated filter plate? We offer carbon steel, stainless steel (304, 316, 316L), and other alloys depending on the application. The material can be selected based on your corrosion and abrasion requirements.
- Can you customize the hole shape and pattern? Yes, we can produce round, square, slotted, hexagonal, or custom-shaped holes. The pattern (staggered, straight, etc.) is also adjustable to meet your flow and strength needs.
- What is the minimum order quantity (MOQ)? Our MOQ is typically 10 pieces for standard sizes, but we can discuss smaller quantities for sample orders or trial runs. Contact us for details.
- What is the typical lead time for OEM orders? Lead time depends on the complexity and quantity. For standard plates, it is usually 15–25 working days after drawing approval. Larger or custom orders may require 30–40 days.
- How do you ensure the flatness and dimensional accuracy of the plates? We use CNC punching machines with precise tooling, followed by flattening and inspection processes. Each plate is checked with gauges and templates before shipment.
- Do you provide samples before mass production? Yes, we can provide samples (cost and shipping to be covered by the buyer). Once the sample is approved, we proceed with bulk production.
- What packaging do you use for export? Plates are packed with reinforced wooden crates, with protective layers between each plate to prevent scratches and damage during transit. We also offer custom packaging per request.
