Dingmetal is a China-based custom heatsink manufacturer, specializing in tailor-made thermal solutions built to your layout or design. Our products are widely used in electronics, telecom, EVs, LED lighting, and industrial equipment—anywhere efficient heat dissipation is required.
We use advanced multi-axis CNC technology and tooling to address the challengesassociated with machinina heatsink fins
Advanced 3-axis, 4-axis, and 5-axis CNC machining (FANUC, Mazak) for precision turning, milling, and contouring of complex heatsink designs.
Over 50 CNC machining centers deliver ±0.02 mm accuracy and stable repeatability — ideal for prototypes and mass production.
Aluminum and copper as standard; stainless steel, brass, titanium, and engineering plastics available on request.
Anodizing, sandblasting, powder coating, electroplating, polishing, and laser engraving — customized finishes supported.
Rapid prototyping and flexible mass production. Typical lead times: 3 weeks for samples, 4–6 weeks for bulk orders.
Dingmetal provide high precision mass-produced heat sinks with complex features, cut-outs, through-holes, and so on.
Geometry Adjustments: Change height, base size, or overall dimensions.
Surface Finish Options: Choose from various surface treatments for performance or appearance.
Structural Modifications: Add through holes, tapped holes, or pedestals as needed.
Assembly Features: Integrate push-pins, shoulder screws, or thermal interface materials (TIM).



Dingmetal has over 10 years of experience in heat sink manufacturing, offering a wide range of heat sinks solutions — trusted across telecom, data centers, EVs, LED lighting, industrial systems, and medical devices. Backed by a 20,000 m² advanced facility with CNC machining, extrusion, forging, and die-casting lines, we deliver reliable thermal performance, consistent quality, and scalable production to meet your demanding applications.
We handle parts from drawings or complex 3D designs, offering rapid prototyping and small-batch production within 7 days for urgent projects. With materials including aluminum, copper, stainless steel, iron, and engineering plastics, and surface treatments such as anodizing, nickel plating, passivation, and powder coating, Dingmetal ensures precise, durable, and high-quality heat sinks that help you accelerate time-to-market.
Whether you need small-batch samples or full-scale production, Dingmetal adapts to your purchasing plan. MOQ starts from 10 pcs for standard models and 50 pcs for custom units, ensuring smooth transition from R&D to mass production.
We start by discussing your specific requirements and exploring design options for your custom heat sinks to meet your thermal and mechanical needs.
After finalizing the design, we provide a detailed quotation that includes pricing and lead times, ensuring complete transparency to help you make informed decisions.
Upon confirming the quotation, we will send a sample for your approval, allowing you to assess the performance and quality.
Once you approve the sample, we will make any final adjustments if needed and then prepare for mass manufacturing of the heat sinks.
Upon sample approval, we enter the official molding process to create the custom heat sinks for large-scale production, ensuring consistency and precision in every unit produced.
Once the molds are finalized, we move to mass production. Our team maintains high standards and ensures on-time delivery for your order.
