Frequently Asked Questions (FAQs)

Are you a manufacturer or a trader?

When dealing with machining companies in China, it’s important to know if you’re working directly with a manufacturer or a trader. Most reputable companies, like those mentioned, are manufacturers themselves, located in industrial parks and capable of producing precision CNC machined and die casting parts. This ensures you get products directly from the source, often with better control over quality and pricing.

What is the highest precision/tightest tolerance you can achieve?

The precision of CNC machining in Chinese factories is quite high. Typically, these companies can achieve tolerances up to ±0.005mm, with some even reaching ±0.002mm. This high precision is crucial for producing parts that meet strict specifications, especially in industries like electronics, aerospace, and automotive.

What materials can you work with?

Chinese machining companies are versatile when it comes to materials. They can work with a wide range of materials including stainless steel, carbon steel, aluminum alloy, zinc alloy, brass, titanium alloy, and various plastics like PTFE and PMMA. This variety allows you to choose the best material for your specific application.

How do you ensure the quality of each product?

Quality control is a top priority in these factories. Each process is inspected by a quality inspection department to ensure every product meets the required standards. Additionally, sales staff follow up on your order throughout the production line, and detailed inspection reports are provided to guarantee quality.

What are the typical payment terms and lead times?

Payment terms usually involve a deposit upfront, with the balance paid before shipment. For example, payments under $1000 might require 100% in advance, while larger amounts might require 30% upfront and the balance before shipping. Lead times vary but typically range from 15 to 20 days for mass production, depending on the order quantity and complexity of the parts. Shipping can be via air or sea, with options like DHL, UPS, and FedEx available.
