FAQ
Yes. We support full customization based on CAD drawings (DXF, DWG, PDF, AI formats accepted). Custom slit width, aperture size, thickness, and surface treatment are available.
Q2: What is the minimum slit width or hole diameter you can achieve?
For precision slits, apertures, and other etched micro-structure products, the minimum feature size can reach 0.01 mm (10 μm), depending on material type and thickness.
Typical feature tolerances range from ±5 μm to ±10 μm, subject to design complexity and process selection.
For ultra-precision components, we will evaluate the drawing and technical requirements to determine whether chemical etching, high-precision laser cutting, or a combination of both processes is most suitable to achieve the required accuracy and performance.
Final capability and tolerance control will be confirmed after technical assessment.
Q3: What manufacturing capabilities do you offer?
We provide a complete precision metal manufacturing chain, including chemical etching, high-precision laser cutting, CNC machining, and various secondary processes.
Based on your drawings and technical requirements, we evaluate and recommend the most suitable manufacturing method to achieve the best balance between precision, performance, and cost.
We also offer a wide range of surface treatments, such as blackening, plating, and other customized finishes.
With our integrated production capabilities, you can avoid coordinating multiple suppliers for different processes. We provide a comprehensive one-stop solution to simplify your supply chain and improve project efficiency.
Q5: What tolerances can you achieve?
Feature tolerance is typically ±5μm to ±10μm depending on the process and thickness. Overall dimensional tolerance is generally ±0.01 mm.
Q6: Which processing method is better — etching or laser cutting?
Chemical etching is ideal for micro precision features with smooth edges and no mechanical stress. Laser cutting is suitable for thicker materials and larger features. We recommend the best method based on your design.
Q7: Do you provide rapid prototyping?
Yes. 24-hour rapid prototyping is available for simple designs, depending on material and workload.
Our MOQ starts from 1 piece. We support low-volume and prototype orders as well as mass production.
Q2: What payment methods do you accept?
We accept T/T (bank transfer), PayPal (mainly for samples and small orders), and secure payment methods supported by the Made-in-China platform, which provide transaction protection for both buyers and sellers.
We also support other internationally recognized third-party payment platforms upon agreement. Payment terms can be discussed based on order value and cooperation history.
Q3: What is your lead time?
Standard sample lead time is typically 3–7 working days, depending on design complexity and material availability.
For urgent projects, 24-hour rapid prototyping is available for qualifying designs. Expedited production can be arranged upon prior communication.
Mass production lead time is generally 15–30 days, depending on order quantity, design complexity, and processing requirements. The final schedule will be confirmed after technical evaluation.
Q4: What shipping methods are available?
We support international express shipping (DHL, FedEx, UPS) as well as economical shipping options such as air freight or sea freight.
Express shipping to the US and EU typically takes 5–7 days.
Sea freight may take approximately 15–21 days, depending on destination and schedule.
We will recommend the most suitable shipping method based on urgency and budget.
Q5: How do you ensure product quality?
Quality assurance begins with detailed sample confirmation to ensure all technical requirements are clearly defined.
During mass production, we implement strict in-process inspections and final dimensional inspections before shipment. Our quality control procedures ensure consistency, precision, and compliance with drawing specifications.
