According to drawings, heat resistance, surface treatment requirement, Various types of 2D or 3D drawings are acceptable, etc.

Integrated production from mold-making to post-processing is completed in our own factory.
This can effectively reduce the manufacturing cost.
We have first rate production line, the most professional staff, and the advanced equipment and inspection method for casting.
super quality,competitive price and strict delivery time.


Pls send the drawing,technical requirements to us by email.
Looking forward to receiving your inquiry and reply.
Thank you.
