19×10 Custom Forged Monoblock Sample Wheel – Electroplated Black 3-Spoke Design 5×120.65

Engineering Notes

XINGTU’s engineers want to highlight three details that define this sample project.

Three-Spoke Forged Monoblock Design

The 19×10 wheel features three broad, sculpted spokes extending from the central hub toward the outer rim. A large oval opening within each spoke introduces a distinctive open pattern, while smaller machined recesses around the center and outer face add depth to the design.

The forged monoblock construction integrates the hub, spokes and barrel into a continuous aluminum body. CNC machining forms the oval openings, curved spoke edges and recessed details directly within the wheel, without separate bolted center components.

The generous spoke surfaces give the design its recognizable three-spoke character, while the machined openings create a contrast between solid aluminum sections and open areas. The finished sample weighs 11.2 kg and has a stated load rating of 800 kg.

Electroplated Black Finish

The electroplated black finish creates a dark, reflective surface that follows the contours of the three-spoke design. Unlike an opaque painted finish, its metallic reflections reveal subtle changes in depth across the broad spoke faces, oval openings and recessed outer-rim sections.

Achieving a consistent appearance across these different surfaces requires careful polishing and preparation before electroplating. The smooth spoke faces and curved openings make surface waves, polishing marks and other imperfections particularly noticeable under reflective lighting.

The finishing process includes surface refinement, polishing, cleaning, activation and electroplating, followed by a final appearance inspection. These additional surface-treatment stages form part of the 45-day production schedule.

Custom Sample Dimensions & Mounting Geometry

The completed sample measures 19×10 with an ET38 offset, 5×120.65 bolt pattern and 70.3 mm center bore. Its mounting configuration includes a 15×32×60° taper-seat specification.

These dimensions define the sample's production geometry and provide a basis for evaluating the machined hub, mounting surfaces and overall wheel proportions. The sample can support further design and production discussions, with vehicle compatibility determined by the requirements of the intended application.

From Design to Delivery

• PCD, center bore and ET dimensions inspected
• 15×32×60° taper-seat profile checked
• Wheel weight verified at 11.2 kg
• Radial and lateral runout inspected
• Three-spoke geometry and oval openings checked
• Electroplated surface inspected for polishing waves, pits and coating defects
• Dynamic balancing completed before sample delivery

Result

The finished sample brings the distinctive three-spoke design into a fully machined forged monoblock wheel, with large oval openings and recessed details that define the shape of each spoke.

Electroplated Black adds a reflective metallic appearance, highlighting the transitions between the broad spoke surfaces, machined openings and outer rim. The completed 19×10 wheel weighs 11.2 kg and retains the intended ET38 mounting geometry.

The sample provides a physical reference for assessing the wheel's proportions, machining details and surface finish before further production decisions.

Wheel Dimensions & Mounting Specifications

The 19×10 forged monoblock sample features an ET38 offset, 5×120.65 bolt pattern, 70.3 mm center bore and 15×32×60° taper-seat configuration. These specifications define the sample's mounting geometry. Vehicle installation requires compatible hub dimensions, fasteners, brake clearance and tire specifications.

Forged Three-Spoke Construction

Three broad spokes connect the central hub to the outer rim within a one-piece forged aluminum structure. Large oval openings and smaller machined recesses create the distinctive three-spoke appearance. The finished sample weighs 11.2 kg and has a stated load rating of 800 kg.

Electroplated Black Surface Finish

The wheel features an Electroplated Black finish with a dark, reflective metallic appearance. Polishing and surface preparation refine the spoke faces, curved openings and recessed details before electroplating, helping maintain a consistent finish across the completed wheel.

FAQs

1. Can These Three-Spoke Forged Wheels Be Customized for Different Vehicles?

Yes. Wheel dimensions, offsets, center bores and mounting specifications can be discussed for different vehicle applications. This sample features a 19×10 size with an ET38 offset and 5×120.65 bolt pattern. Confirm your vehicle's hub, brake clearance and tire requirements before finalizing a new configuration.

2. What Are the Weight and Load Rating of the Wheel?

The finished 19×10 sample weighs 11.2 kg and has a stated load rating of 800 kg. Its forged monoblock construction combines the three spokes, center hub and barrel in a single aluminum body.

3. Can I Develop a Custom Three-Spoke Design from My Own Drawings?

Yes. Custom wheel development can begin with your drawings, reference images and dimensional requirements. Spoke profiles, machined openings, wheel dimensions and surface finishes can be reviewed as part of the sample development process.

4. Is the Black Finish Painted or Electroplated?

This wheel features an Electroplated Black finish. The electroplating creates a dark, reflective metallic surface across the spoke faces and machined details. Polishing and surface preparation help maintain a consistent appearance before the final plating stage.

5. Can I Review a Sample Before Proceeding with a Larger Order?

Yes. A physical sample allows you to examine the spoke geometry, machining details, wheel dimensions and surface appearance before discussing subsequent production. Share your design requirements and inspection priorities when planning the sample.

6. How Long Does Custom Wheel Sampling Take?

The production lead time for this Electroplated Black forged wheel sample is approximately 45 days after the design and specifications are confirmed. The process includes CNC machining, polishing, electroplating, dimensional checks and final inspection. Shipping time varies by destination.
