Frequently Asked Questions

Find answers to common questions about aluminum processing in China, material selection, and international orders.

Common Questions About CNC Metal Parts in China

What quality standards do Chinese CNC machining follow?
Leading Chinese CNC machining adhere to international standards including ISO 9001, ISO 14001. Our facilities maintain strict quality control systems with regular third-party audits to ensure consistent product quality.
What are the minimum order quantities for cnc machining?
Minimum order quantities vary based on product specifications, complexity, and processing methods. For standard profiles, MOQs typically start at 2pcs. Contact our sales team for specific product requirements.
What is the typical lead time for CNC machining in China?
Urgent order 3-7days, Complex projects or large orders may require 20-30days. Express processing options are available for urgent requirements at an additional cost.

Material Selection Guide

Which aluminum alloy is best for outdoor applications?
For outdoor applications, we recommend 6063-T5/T6 for general structural uses, 6061-T6 for higher strength requirements, and 5052 for marine environments. These alloys offer excellent corrosion resistance and can be further enhanced with anodizing or powder coating treatments.
How do I choose between aluminum and other metals?
Consider aluminum when you need a lightweight yet strong material with excellent corrosion resistance. Aluminum is ideal for applications requiring good thermal conductivity, non-magnetic properties, and recyclability. Steel may be better for extreme load-bearing, while stainless steel offers superior corrosion resistance in certain environments.
What surface treatments are available for aluminum?
We offer multiple surface treatments including anodizing (clear, colored, hard), powder coating, PVDF coating, brushing, polishing, and chemical conversion coatings. Each treatment provides different aesthetic and functional properties to meet your specific requirements.

Processing Methods Comparison

What's the difference between extrusion and die casting?
Extrusion involves pushing aluminum through a die to create profiles with consistent cross-sections, ideal for long components like frames and rails. Die casting injects molten aluminum into molds to form complex shapes with excellent dimensional accuracy, better suited for intricate components with detailed features.
When should I choose CNC machining over other methods?
Choose CNC machining when you need high precision, complex geometries, or small production runs. It's ideal for prototyping, creating parts with tight tolerances, or when secondary operations are required on extruded or cast parts. For large volume production, extrusion or die casting may be more cost-effective.
What are the cost implications of different processing methods?
Extrusion has lower tooling costs but higher minimum quantities. Die casting has higher initial tooling costs but excellent unit economics at scale. CNC machining has minimal tooling costs but higher per-unit costs. The optimal choice depends on your production volume, complexity requirements, and budget constraints.

International Order Process

What is the typical ordering process for international clients?
The process begins with inquiry submission and technical review, followed by quotation, sample approval (if needed), formal order placement with deposit payment, production, quality inspection, balance payment, and shipping. Our international sales team provides support throughout the entire process.
What shipping and payment terms are available?
We offer flexible shipping terms including FOB, CIF, and DDP. Payment options include T/T (30-70% structure), L/C at sight, and trade assurance through platforms like Alibaba. For established clients, we can discuss more favorable payment terms based on order history and volume.
How do you handle quality control for international orders?
We implement a comprehensive quality control system including incoming material inspection, in-process checks, and final inspection before shipping. For international orders, we provide detailed quality reports with dimensional measurements, material certifications, and performance test results. Third-party inspection can be arranged upon request.
