Stable molding of complex heat dissipation structures
Communication Die Casting Mold
Precision structure manufacturing technology
In the communications industry, Raidy mold manufacturers possess the capability to realize a variety of highly complex structures. We can produce heat sinks in the following ways:
Ultra-thin heat sink structures (0.8 mm level)
High aspect ratio heat sinks (60–90 mm height)
Precision structures with small draft angles (0.5°–0.8°)
High-density array heat dissipation structures
Complex structures with multiple modules/inserts
These structures are typically used in the extreme heat dissipation designs of high-power communication equipment, placing high demands on both die-casting mold design and die-casting processes.

Can you produce die-cast parts with ultra-thin heat sink structures?
Yes.
We have the capability to develop die-casting molds for communication heat sink structures, enabling us to reliably produce ultra-thin heat sink structures, such as aluminum alloy heat sinks with a wall thickness of 0.8mm, while ensuring consistency in mass production.
Can high aspect ratio heat sinks (e.g., 60–90mm in height) be die-cast?
Yes.
Through optimizing the filling system, cooling structure, and high-vacuum die-casting process, we can reliably form high aspect ratio heat sink structures, ensuring the integrity of the end filling and structural stability.
What are the requirements for mold design in high-vacuum die casting?
High-vacuum die casting places higher demands on mold sealing, venting systems, and structural stability.
We employ a dedicated vacuum channel design and a zoned venting system to ensure stable cavity vacuum, thereby improving the filling capacity of thin-walled structures and the density of the product.
What are the common defects in die-cast communication heat sinks?
Common issues include: Short shot, porosity, cold shut, mold sticking, and incomplete filling. These problems are mainly related to structural design, mold venting, and die-casting process parameters. However, raidymold can solve these problems.
How do you solve the short shot problem in thin-walled heat dissipation structures?
We solve it through the following methods: Optimizing the gating system to improve molten metal flow; Designing directional filling paths; Enhancing venting efficiency; and Using high-vacuum die-casting processes. This improves the filling integrity of thin-walled structures.
Do these communication heat dissipation die-casting molds support mass production?
Yes, mass production is supported.
Our mold design not only focuses on successful trial molding but also emphasizes optimizing thermal balance and structural stability to ensure mold consistency and lifespan in long-term production.
Can you provide early DFM or mold flow analysis?
Yes.
We can provide DFM manufacturability analysis and Moldflow simulation before mold development to identify risks in advance and optimize structural design, improving the success rate of first-time trial molding.
