Metal Parts

Quick Info

Metal Parts can be produced through various manufacturing processes, such as CNC Machining, Die Casting and Sheet Metal Stamping, while one may have advantages and disadvantages from another. With decades manufacturing experience & expertise in industrial parts, GEMS-MFG well understand the differences of multiple metal forming methods. In order to assist you in achieving the desired part attributes, including but not limit to strength, heat and electrical conductivity, aesthetics, surface protection, corrosion resistance and others, we will discuss and recommend the best manufacturing process for your application.

Taking Die Casting for example, it is a manufacturing process that pours or injects molten metals into molds, which allows each part to be generated with accuracy and repeatability. Die casting is a productive, affordable process that offers a wider variety of shapes and parts than any other production method. Parts can be made to suit the counterpart’s aesthetic and have a long service life. Designers can benefit from die cast parts’ fast production, tight tolerances, dimensional precision and stability, strength, variety of surface finishes, and streamlined assembly processes.

Our metal parts are concentrated on the applications of medical, automotive, renewable energy, lighting and electronics, home appliance, machinery, furniture, industrial tools and others. To know details about our engineering and manufacturing capabilities for metal parts and how we serve the above industries, please contact us right today.



  • Aluminum alloys can be produced into a variety of product with various shapes, sizes, and thicknesses using the aluminum die casting process, which is thought of highly versatile for it dimensional stability and thin-wall feasibility. For applications in almost all industries, the aluminum die casting method also produces lightweight components, maintains high operating temperatures, and offers outstanding corrosion resistance.
  • The fact that aluminum die casting produces lighter parts with more surface finishing options than other die cast alloys, including aluminum anodizing, spraying and powder coating. Of all the die-cast alloys, aluminum can sustain the highest operating temperatures. Additionally, cast aluminum has thin walls, good dimensional stability, and is resistant to corrosion. Obviously, aluminum die casting may be used for a wide of metal products, but specially practical for LED lighting components.


  • Sensitive electronic assemblies are housed and protected in die cast metal enclosures for both indoor and outdoor environments. There are multiple benefits to use aluminum or magnesium alloy to cast die casting enclosures for electronic products. Not only it provides some EMI/RFI attenuation function for equipment and applications out of the box, but it also has super rigidity and strength-to-weight ratios of any structural material. It is also used to shied medical and laboratory equipment from other interfering signals in hospital and testing center etc.
  • Diecast metal enclosures are frequently used in industries including medical, electrical, transportation, and more. If a minimum weight requirement was the main consideration in this type of application, magnesium alloy would be considered as priority choice. Please contact GEMS-MFG to learn more about the special advantages of die cast electronic enclosures that enable them to thrive in so many various applications.


  • Magnesium alloy is famous for its special solidification properties, such as superior fluidity and a lower sensitivity to hydrogen porosity, which result that it is more castable than other cast metals like aluminum and copper. With nearly 98% of magnesium’s structural applications, die casting has no doubt to be the dominant method of fabricating magnesium components.
  • The use of magnesium die casting components for cell phone manufacturing is growing in popularity, as it offers many advantages over traditional metal or plastic materials. Magnesium die casting process can be used to create complex shapes, precise details, and even intricate patterns. It is also less expensive, faster to produce, and require less labor than other types of manufacturing like CNC machining.
  • Taking the great advantage of castability for magnesium alloys, the majority of product development has been concentrated on thin-wall die casting applications in the mobile phone industry. For the situation that rising energy demand, environmental protection and governmental regulations in the coming decades, it will encourage more needs for lightweight magnesium die castings. Magnesium die casting applications have recently expanded into the automotive, defense, aerospace, electronics, and power tool fields.


  • Zinc alloy die casting is widely used for producing robust, precise, and complicated metal components, as it is one of the most versatile, effective and adaptable high-volume production process. With the advantage that the molten metal quickly cools and solidifies in shorter time when it comes into contact with the relatively cool steel side, pressure zinc die castings typically have better mechanical qualities than other casting techniques.
  • Zinc alloy features the property of excellent casting fluidity, strength, and stiffness, which makes it possible to build thin wall sections that can lower weight and save raw material. From mold design and testing to zinc component casting, machining, finishing and packing, GEMS-MFG is proud of offering one stop zinc alloy die casting service to clients. We are capable of converting even the most complex design specifications into a final product thanks to zinc’s superior bearing and wear qualities, which increase design flexibility and lower fabrication costs.


Integrated Factory Resources

We are your one-stop manufacturing solution provider for customized products with the joint effort & support from our 120 partnership subcontractors mainly for the production of metals & plastics. We can expand much faster but the top management decide to keep GEMS a compact, dedicated and professional company, which allows our team to really focus and deliver on your projects without any excuse or compromise. We strive to be a long-term, reliable and trustworthy partner of our customers rather than just being a contractor, and look forward to growing the company with customers’ success.

Manufacturing Veteran Team

With the passing years, we are proud to build up a manufacturing veteran team with rich experience and full expertise to fulfill your specific demand. From mold making, injection molding, die casting, stamping and sheet metal, to 2nd processes like CNC machining, oil spraying, powder coating and chrome plating, and then assembling and packaging and related, we always have someone in house to be an expert to resolve the issues in different stages of product development. We also specialize in providing charger, cable and hub, plus other electronic accessories that support a complete set of product.

Strong Project Management

“Think global, act local” is the principle of our work. Time, quality and cost are the three key elements to be considered throughout the product development from concept design to mass production. A detailed plan with weekly conference call update is a critical gateway to ensure these three key elements are successfully implemented, also assuring that all parties are on the same page. Communication is the Secret to Success . Everyone works independently to take care his own job, but together we are a team to get things done and are your daily eyes and ears onsite in China.

Flexible Operation & Customization

We offer a wide variety of products, such as mold, component and assembly product, and certain value-added services. For logo or branding product, we have in house resources to complete a color mix that can perfectly match a brand’s unique colors in fast and cost-effective way. Understood the client needs production parts but having a hard time to find a vendor since the order quantity is as low as 1000 or lower. GEMS is well set up for low volume injection molding or die casting projects. Surely our team is also capable of building SPI Class 101 mold that is designed & made for 1 million cycles or more of producing the same high quality parts consistently.
