Samsung and LG, the world's leading manufacturers of electronics and communications products, require a large number of communications components every year. CASTMAN has a lot of experience in optimizing telecom die casting parts and has the ability to produce high quality products at low cost for customer concept development.

Aluminum die cast heat sinks are used to cool a variety of electronic components and devices.
Castman uses superior die casting process and technology to manufacture aluminum heat sinks and heat sink components to customer specifications and designs. Our goal is to provide high quality aluminum heat sinks and components at an affordable price.
Aluminum die cast heat sinks are electrically conductive and can be electrically grounded. You don't have to pay extra for copper plating, and heat sink components are used for RF and EMI shielding. Die-cast aluminum heat sinks are sturdy and can be molded to eliminate secondary operations such as machining and assembly to reduce cost.

The aluminum heat sink is specially designed to cool the parts of electronic devices, and the cooling fins, mounting holes and mounting functions can be manufactured at the same time. Die-cast heat sinks can be used as raw parts without finishing, or anodized or powder coated to improve surface protection and corrosion resistance.

In addition to the typical “fin” design of the heat sink, CFDs can be used to improve the design to cool the heat at the highest possible speed in a specific area of ​​the product.

Die Casting Benefits for Telecommunications

Communication engineers face the challenge of designing in a highly dynamic technology environment. Continuous innovation means that time to market is critical while ensuring a large supply of high-quality components. CASTMAN offers a die-cast solution for all types of communication applications and is at the cutting edge of the design for new types of communication equipment. From fiber optic transceivers to satellite communications, CASTMAN offers innovative solutions for every project.

When designing a communication connector or device, partnering with CASTMAN provides the following benefits:

Fiber Optic Connector

Creating small precision fiber components requires superior quality and consistency. For complex components with thin walls, such as fiber optic transceivers, it is important to know that the components are not easily broken or worn, especially under harsh environmental conditions such as high temperatures and high humidity. The CASTMAN completes the accelerated life test to validate the connector components to ensure the success of the components.


The die cast components are used in a wide range of networking equipment, from aluminum cast RF filter boxes at base stations to high precision cast zinc pins in switching systems. Heat sinks of various materials, including copper, in shield boxes for microwave ovens. One of the most widely used applications is the connector housing that CASTMAN manufactures in all shapes and sizes.

Robust and complex components

The die cast housing is durable, allowing for the integration of heat sinks into the product design. Die casting, which minimizes the extra weight of the shield and frame, provides the maximum stiffness benefit for small, lightweight devices. Designing as a minimum draft means that the part can contain internal functionality without secondary action. Increase accuracy and reduce customer costs. CASTMAN continues to carve out elements developed through innovations in zinc, aluminum and magnesium.

The LED lighting industry needs core technology for LED components that require thin walls and multiple heat sinks due to rapid technological change. CASTMAN uses numerical analysis(CFD) and analysis technology to provide reliable products and technical services.


Medical appliances

The challenge of medical device design is to strive for end products that address clinical needs, human errors, and patient safety. Medical device design is becoming more complex and technologically challenging because device manufacturers pay close attention to the consumer electronics industry when considering design and usability developments. Minimalization continues to be a hot trend in medical device design, and faster-to-market than ever is a major competitive advantage in product launch. CASTMAN provides precision diecast components for medical devices that meet the needs of multiple users, various environments, and patient variability.


Stainless steel and machined aluminum are not the only choice for manufacturing parts in contact with the human body. If medical devices need to interact with tissue or body fluids, various special coatings can be applied to die castings to meet the rigorous testing and verification required by FDA/EMEA. CASTMAN offer a variety of alloys, so you don't have to limit your choice of materials.

Medical and surgical applications
surgical instruments

Surgical devices can be as specialized and diverse as the medical field. Traditionally, stainless steel and processed aluminum have been considered the only substances that meet FDA approval for manufacturing bio-compatible medical devices. However, the various components that go into medical devices today are die casting. Zinc die casting provides significant cost savings for medical device companies, and CASTMAN's die casting process, however small or complex, helps manufacture these components.

Treatment & Diagnosis

Intelligent treatment and diagnostic devices used to screen, evaluate and diagnose patients should be designed with a high degree of sophistication for easy and effective laboratory use in patient homes. Providing state-of-the-art tools with ergonomic design for device manufacturers means considering durability, appearance, and weight in addition to functionality. CASTMAN's precision components offer a variety of options that exceed the requirements for design flexibility, material, precision, and surface finish.
