Frequently Asked Questions (FAQs)

What certifications should I look for in a Chinese machining vendor

When selecting a machining vendor in China, it’s crucial to check for certifications that ensure high-quality and compliant parts. Look for ISO 9001 certification, which guarantees adherence to quality management standards. For environmental efficiency, ISO 14001 is important. If you’re producing parts for specific industries like medical or aerospace, certifications such as ISO 13485 or industry-specific standards are essential.

What types of materials can Chinese machining vendors process

Chinese machining vendors can process a wide range of materials, including various metals like aluminum, stainless steel, titanium, and copper, as well as engineering plastics such as PEEK, Nylon, and PMMA. They can also handle complex materials like composites and specialty alloys, ensuring you can get the parts you need regardless of the material requirements.

How do I get a quote and what information do I need to provide

To get a quote from a Chinese machining vendor, you typically need to provide your CAD data in formats like STEP, IGES, X_T, or STL, along with 2D drawings in DWG or PDF if dimensional tolerances are required. You should also specify the material, surface treatment, and quantity needed. Some vendors allow you to upload this information through their website or via email.

What is the typical production and delivery time for machined parts

The production time for machined parts in China can vary based on the complexity and quantity of the order. For prototypes, it can take anywhere from 3 to 9 days, while larger production runs or processes like rapid mold and injection molding may take 2-5 weeks. Delivery times depend on shipping methods, which can range from a few days by air to several weeks by sea.

How do Chinese machining vendors ensure quality control and precision

Chinese machining vendors ensure quality control through various measures. They use advanced CNC machining equipment, such as 2-, 3-, 4-, and 5-axis machines, to maintain high precision. Additionally, they employ quality control teams that use tools like coordinate measuring machines (CMM), height gages, and microscopes to inspect parts. They also conduct manufacturing feasibility analyses (DFM) to optimize designs and ensure parts meet your specifications.
