Mechanical Finishes

Physical processes that improve surface flatness, smoothness, and texture.

● Sanding / Grinding: Removes machining marks and smooths surfaces.

● Polishing: Improves surface smoothness and gloss.

● Brushing: Creates uniform directional surface textures.

● Sandblasting / Bead Blasting: Removes oxides and creates a matte textured finish.

Protective Finishes

Chemical and electrochemical processes that enhance corrosion resistance and surface protection life.

● Anodizing (Type II / III): Forms a protective oxide layer for improved corrosion and wear resistance.

● Electroplating: Applies a metal coating to improve corrosion resistance, conductivity, and appearance.

● Hot Dip Galvanizing: Creates a thick zinc coating for long-term corrosion protection.

● Dacromet Coating: High salt spray resistant zinc-aluminum anti-corrosion coating.

Decorative & Marking Finishes

Processes that enhance appearance quality and apply permanent identification.

● Anodizing Coloring: Adds durable and uniform color after anodizing.

● Powder Coating: Forms a durable and weather-resistant protective coating.

● Paint Spraying: Creates decorative and protective surface finishes.

● Pad / Silk Printing: Applies logos, labels, and markings onto surfaces.

● Laser Marking: Permanently engraves logos, serial numbers, and codes.

Hardening & Functional Treatments

FAQ

Do you accept prototype or small-batch orders?

Yes. We can flexibly handle orders from single prototypes to mass production.Sample lead time is typically 3–7 working days.
What is your Minimum Order Quantity (MOQ)?

We have no MOQ for CNC machining — prototypes, small batches, and mass production are all welcome.
What is your production lead time?

For samples: 3-7 days. For mass production: 10-30 days after order confirmation, depending on the order quantity and part complexity. Rush services are available for urgent projects.
What’s your product price?

As all parts are custom-made, we don’t have a fixed price list. Pricing depends on the part’s design, material, surface finish, and quantity. Once we receive your drawings or requirements, our team will evaluate them and provide an accurate quotation within 24 hours.
What are your payment terms?

Our standard payment terms are:

Orders < $1,000: 100% payment in advance.

Orders ≥ $1,000: 50% deposit, 50% balance before shipment.

We are flexible and can discuss terms for long-term projects.
How do you arrange shipping and delivery?

We offer various delivery options — express (DHL, FedEx, UPS), air freight, fast sea shipping, China–Europe Railway, and standard sea freight — under FOB, CIF, or DDP terms. Typical transit times: 3–5 days by express, 7–10 by air, and 20–45 by sea or railway.
What information do I need to provide for a quotation?

To provide an accurate quote, please share 2D drawings (PDF/DWG) and 3D models (STEP/IGS/X_T preferred) along with quantity, material, and surface finish details. If you don’t have drawings, send us a sample or sketch with dimensions — we’ll help create them.
How do you handle quality issues?

If any quality issue is found, we will promptly evaluate the cause and provide corrective, rework, or remake solutions to ensure the parts meet specifications.
Can you sign a Non-Disclosure Agreement (NDA)?

Yes. We strictly protect customers’ intellectual property and design confidentiality, and can sign an NDA to ensure project security.
What if I don't have drawings? Can you help?

Of course. We offer ODM (Original Design Manufacturing) services — you can simply provide sketches, photos, or reference samples, and our engineering team will help turn your idea into a manufacturable design.
