How to Work with Us for
Custom Heat Sinks

Step 1: Design and Discussion

We start by discussing your specific requirements and exploring design options for your custom heat sinks to meet your thermal and mechanical needs.

Step 2: Quotation

After finalizing the design, we provide a detailed quotation that includes pricing and lead times, ensuring complete transparency to help you make informed decisions.

Step 3: Sample Production

Upon confirming the quotation, we will send a sample for your approval, allowing you to assess the performance and quality.

Step 4: Customer Approval

Once you approve the sample, we will make any final adjustments if needed and then prepare for mass manufacturing of the heat sinks.

Step 5: Official Molding

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.

Step 6: Mass Production

Once the molds are finalized, we move to mass production. Our team maintains high standards and ensures on-time delivery for your order.
