Chemical Etching Stainless Steel Tea Strainers with High Precision

Chemical Etching Stainless Steel Tea Strainers with High Precision

Tea Strainer Overview

Xinhaisen Technology crafts high-performance stainless steel tea strainers using advanced chemical etching technology. Our precision-etched mesh delivers optimal tea infusion while ensuring durability, easy cleaning, and elegant designs for both commercial and home use.

Manufacturing Process

We produce our tea strainers through a precise photochemical etching process:

• Material Selection: Choosing food-grade stainless steel or other suitable metals.

• Cleaning & Preparation: Ensuring the metal sheet is perfectly clean.

• Photo Tooling: Applying a light-sensitive resist and exposing it to UV light with the strainer design.

• Precision Etching: Using chemical etchants to accurately form the mesh patterns and shapes.

• Finishing: Removing residues, deburring for smooth edges, and applying final cleaning/polishing.

• Quality Control: Inspecting each strainer for hole uniformity, size, and finish.

Tea Strainer Features

• Food-Safe & Hygienic: Made from food-grade materials (e.g., 304/316 stainless steel), resistant to rust and corrosion.

• Ultra-Fine Mesh: Precision-etched micro-holes ensure excellent filtration of tea leaves without allowing debris to pass through.

• Burr-Free & Smooth Edges: Etching creates smooth surfaces and edges, safe for handling and easy to clean.

• Custom Designs: Ability to create any shape, pattern, or logo directly into the mesh or surrounding frame.

• High Durability: No mechanical stress during manufacturing ensures the metal retains its strength and does not warp.

• Consistent Quality: Every strainer has uniform hole size and distribution for reliable performance.

Tea Strainer Specifications

Tea Strainer Applications

• Commercial Tea Infusers: For tea bags, disposable or reusable infusion packets, and large-scale brewing systems.

• Consumer Tea Ware: Integrated into tea balls, spoons, mugs with built-in filters, and portable strainers.

• Gourmet & Specialty: High-end strainers for loose-leaf tea, herbal infusions, and spice filtering.

• Custom Promotional Items: Branded tea strainers as corporate gifts or promotional merchandise.

FAQ

• Q1: What materials do you recommend for tea strainers?
  We primarily recommend food-grade 304 or 316 stainless steel for its excellent corrosion resistance, durability, and safety.
• Q2: Can you make strainers with very small holes to filter fine tea dust?
  Yes. Our etching technology can produce micro-holes as fine as 0.03mm, perfect for ultra-fine filtration.
• Q3: Is it possible to add my company logo to the strainer?
  Absolutely. We can etch logos, text, or decorative patterns directly onto the mesh or the surrounding frame with high precision.
• Q4: What is the minimum order quantity (MOQ)?
  We are flexible and support both low-volume prototyping and high-volume production runs to meet different needs.
• Q5: How durable are etched strainers compared to woven ones?
  Etched strainers are monolithically made from a single sheet, offering superior durability, no fraying edges, and easier cleaning compared to woven mesh.
• Q6: Can you produce strainers in shapes other than circles?
  Yes. The etching process allows for any 2D shape—squares, ovals, animal shapes, or custom silhouettes—with no additional cost for complexity.
