Frequently Asked Questions (FAQs)
Frequently Asked Questions About Manufacturing Tolerance Factories in China
What is manufacturing tolerance and why is it important?
Manufacturing tolerance is the acceptable range of variation in the dimensions of a part. It’s crucial because it helps ensure that the parts you manufacture fit together correctly and function as intended. Without clear tolerances, you might end up with parts that are either too loose or too tight, leading to costly errors and delays.
How do I specify tolerances for my manufacturing project in China?
To specify tolerances, you need to provide detailed design drawings with clear measurements and acceptable deviations. This can be done using unilateral, bilateral, or limit tolerances, depending on your needs. For example, you might specify a part’s diameter as 102.00 ±0.10 mm to allow for equal variation in both directions. Ensuring your drawings are complete and accurate saves time and prevents misunderstandings.
What are the benefits of having complete technical design drawings with tolerances?
Having complete technical design drawings with tolerances reduces manufacturing errors, saves time, and makes the process more cost-effective. Detailed drawings eliminate room for interpretation, streamline communication, and prevent costly mistakes. This approach also improves the fitting of parts together, ensuring your final product meets your quality standards.
How do Chinese factories maintain production during COVID-19 lockdowns?
Chinese factories, especially in tech hubs like Shenzhen, have adapted to COVID-19 lockdowns by implementing “closed-loop” systems. This means keeping workers on site to continue production even during lockdowns. This approach has helped maintain economic growth and minimize disruptions to manufacturing operations.
What are the common types of machining tolerances used in Chinese factories?
Common types of machining tolerances include unilateral, bilateral, and limit tolerances. Unilateral tolerances allow variation in one direction, while bilateral tolerances allow equal variation in both directions. Limit tolerances specify the extreme possible values of a part. Standard machining tolerances, often set by international standards bodies, are also widely used for simpler parts. Understanding these types helps you communicate your design intent precisely to the manufacturers.
