Precision in Every Part, Excellence in Every Detail
Add to Cart
CNC, an acronym for computer numerical control, refers to machining processes controlled by a
computer. CNC machining utilizes computerized automation to manufacture parts more efficiently,
accurately, precisely, and with complex geometries compared to manual machining.
This technology also reduces the need for manual labor in machining tasks that would otherwise be
carried out by human operators. While individuals are not directly involved in physically machining
each part, their pivotal role involves programming and operating the CNC machines to ensure the
smooth execution of every operation.

Post-processing and surface finishes for CNC machining
CNC-machined parts as they emerge from the machine often exhibit visible tool marks, a feature
that may not align with your specific part requirements.
Fortunately, there exists a multitude of post-processing techniques aimed at enhancing the surface
appearance and elevating attributes such as wear resistance, corrosion resistance, and chemical
resistance.
Methods like anodizing, bead blasting, and powder coating present viable options for refining the
final presentation of your custom parts, allowing you to achieve the desired surface quality and
performance characteristics.

Company Profile
FAQ's
1. How long does a quotation take?
Our standard practice involves responding to most Request for Quotation (RFQ) submissions
within a couple of days. Should there be any deviation from this timeframe, we assure you that
we will promptly communicate any delays.
2. How do I know my design will be kept confidential?
Rest assured, we are prepared to sign and strictly adhere to any non-disclosure or confidentiality
agreement you require. Moreover, our factory strictly enforces a policy prohibiting the capture of
photographs of a customer's product without explicit consent.
Our commitment to maintaining confidentiality is underscored by our track record of working with
an extensive array of unique designs over many years, during which we have consistently
safeguarded proprietary information from disclosure to third parties.
3. How does compare to other suppliers on price?
While direct comparisons can be challenging, We generally 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.
In contrast to Chinese suppliers, our strategy is not to compete solely on price. Instead, we prioritize
delivering the highest levels of quality, swift response times, and professional results.
4. How quickly can I get my parts?
High-quality parts can be manufactured in as little as two weeks if you furnish us with comprehensive
2D and 3D CAD models. However, more intricate parts with special features or requirements may
necessitate a longer production time. To obtain more precise lead times tailored to your project,
please request a quote.
Regarding shipping, the majority of our shipments are handled via air freight, taking a few days
for delivery from China to Europe or North America.
