Titanium is a metal with Low Density, low thermal expansion and high resistance to corrosion in sea water, aqua regia, and chlorine. 


Titanium Grade 5 | 3.7164 | Ti6Al4V
Titanium Grade 2
Titanium Grade 1



Polyoxymethylene (POM), also known as an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability.



Nylon – polyamide (PA) – is an engineering thermoplastic with excellent mechanical properties and high chemical and abrasion resistance.



ABS is a common thermoplastic with all-around good mechanical properties, excellent impact strength, good heat resistance and good machinability.



Polycarbonate (PC) is a thermoplastic with high toughness, excellent impact strength and good machinability. Can be optically transparent.



PPSU(PPSF) is a moldable plastic often used in rapid prototyping and rapid manufacturing (direct digital manufacturing) applications. PPSU is heat and chemical-resistant suited for automotive, aerospace, and plumbing applications.

CNC Machining Surface Finishes

Sino-Mold provides multiple finishes to suit your Special Needs.

As Machined

It is the Standard finish of our parts. The “As Machined “has a roughness of 3.2 micrometers (126 micro inches). We remove all sharp edges and burrs.


Anodizing is an Electrochemical process that converts the metal surface into a Decorative, Durable, Corrosion-Resistant, Anodic Oxide finish.

Powder Coating

Powder Coating adds a thin layer to the Protective Polymer on the surface of the is a Strong Wear Resistance finish that is compatible with all metal. Custom color available.


Sandpapers Brush parts with #400-600 grit, which result in a Unidirectional Satin, a finish mostly used for Aesthetic Purposes. 

Bead Blasting

Part is Blasted with tiny Glass Beads using a pressurized air gun, which removes the machine marks and adds a uniform matte and textured on the parts. 


Parts are Polished in multiple directions by hand. The surface is Smooth and slightly is suitable for appearance products—a bit higher cost.


They spray a Thin Layer of Paint on the surface parts, with Custom Colors available. You just need to provide the Panton Color number. Finishes range from matte to gloss to metallic.

Black Oxide

Black Oxide is one of the Conversion Coatings often used on steel. It can improve Corrosion Resistance performance and reduce light reflection.


It produces a Metal Coating on a solid substrate by reducing the Cations of that metal using a direct electric current.

Part Marking

It’s one of the most cost-effective ways to add your Custom Logo or other contents to your parts, which is used in massive production. It’s highly efficient and saves more cost.

Sino-Mold-Consistent Quality Standard

STCNC offers all dimensions Striclty Quality Standards to Maximum your part’s quality.


Our factories strictly adhere to industry standards for threads and tolerances.
* ISO 2768 (m/f) for metal parts, 2768-m for plastic parts, ISO and ANSI/ASME for threads.

Cosmetic Standard

Cosmetic or No-Cosmetic, depending on Our Customer’s Actual Requirements. Usually include Surface Finishes &Visual Inspection. 


STCNC Machining Focuses on 3 Main Factors to ensure you can get ideal Parts, including Edge Breaking, Deburring, and Cleaning.

Inspection Standard

STCNC adheres to industry standard and ISO9001: 2015. We also have our Strictly inspection standard to ensure you can get  Ideal Parts

Quality Reports

We provide quality documentation, such as First Article Inspection, Certificate of Conformance and Material Certificate on request.

Customer Database

After the first cooperation, we create your Personalized Database, which is essential in achieving Consistent Quality for your parts’ production in the future.

From Prototype to Production

Rapid Prototype

We combined a Dedicated Engineering Team with advanced CNC and 3D Printing machines, which make customers’ ideas into reality through Rapid Prototyping.

Accelerated your prototyping development cycles and Shortened your lead time. We know our equipment inside out, and our delivery commitment to you is always based on knowledge rather than an estimate.
