The most suitable application for CNC machining lies in one-off manufacturing endeavors and in
low-to-medium volume production scenarios, typically ranging from several hundred to 1000 parts.
Opting for CNC machining is particularly advantageous when aiming for cost-competitive metal
prototypes. Additionally, the technology shines in situations where the parts necessitate extremely
tight tolerances for precision.
Product Details
CNC machining materials are generally grouped into three primary categories:
plastics, soft metals, and hard metals. This classification includes materials such as aluminum,
bronze, copper, ceramics, plywood, steel, stone, wood, zinc, and various others.
Preference is often given to materials that are considered easy to work with and possess
advantageous properties compared to alternative options.

Company Profile
FAQ's
1. Can make design drawings for me?
Unfortunately, we don't offer an independent product design service. However, for all approved
orders, we provide a Design for Manufacturing review.
This involves collaborating with our clients to enhance their 2D and 3D drawings, ensuring
better manufacturability, resolving design conflicts, and reducing production costs.
Learn more about preparing your CAD drawings for manufacturing.
2. What type of design files does We accept for quoting?
For precise and prompt quoting, we exclusively accept 3D CAD files in STL, STEP, or IGES formats.
For 2D drawings with reference dimensions, please submit them in PDF format.
It's essential to include comprehensive manufacturing information as part of your technical
documentation. Informal communication through Whatsapp, email, etc., will not be deemed
acceptable for manufacturing purposes.
3. How long does a quotation take?
Typically, we aim to respond to Requests for Quotation (RFQ) within a few days of receipt.
In the event of any delays, rest assured that we will promptly notify you of the situation.
4. How does compare to other suppliers on price?
While direct comparisons can be challenging, generally, We offers prices that are typically 25-45%
lower for plastic injection mold tools and CNC machined/turned parts when compared to suppliers
in North America and Europe.
