CNC machining is a process involving different types of machines, all utilizing computer-controlled
tools to precisely remove material from a workpiece.
The advantage of this computerized control is that CNC machining offers significantly increased
speed, precision, and accuracy compared to traditional machining methods.

FAQ's
1. What tolerances can achieve?
Tolerances are not universally defined and vary based on factors such as part size, design
geometry, the number and size of features, material selection, surface finish, and the
manufacturing process.
After order confirmation, we conduct a comprehensive Design for Manufacturing review to
identify areas for potential modification to enhance manufacturability.
It is advantageous if you can specify critical tolerance areas in your design, allowing for
adjustments to optimize production time and costs. General tolerance guidelines are provided
for CNC machining in metal and plastic, plastic injection molding, CNC metals and plastic
injection molding materials, metal 3D printing (+/- 0.5mm), and an expected shrinkage rate
of +/- 0.15% for vacuum casting.
Clear specifications in the 2D drawings are essential for precise adherence to manufacturing
and technical requirements.
2. How quickly can I get my parts?
With complete 2D and 3D CAD models, we can manufacture quality parts in just two weeks.
However, for more complex parts with special features, additional time may be required.
Request a quote for accurate lead times tailored to your project.
Shipping is primarily done via air freight, taking only a few days
from China to Europe or
North America.
3. How does you ensure the quality of my parts?
After order confirmation, we conduct a thorough Design for Manufacturing (DFM) review to
pinpoint any potential issues that could affect part quality. Incoming materials undergo rigorous
inspection and verification using advanced testing equipment.
Final inspection reports are generated before shipment. Moreover, we provide the capability to
share inspection data in real-time, allowing us to collaborate on addressing any quality concerns
that may arise during the production process.
4. What type of surface finishes does provide?
Our services encompass a wide array of finishing options to attain the desired appearance and
texture for your parts. We offer treatments for metal, texturing specifically for plastic injection
mold tools, and painting for both metal and plastic, among other choices.
