Die Casting
What is Die Casting?
Die casting, also known as permanent mold casting, is chosen for its repeatability and precision to mass-produce identical parts made from low melting point metals such as aluminum and zinc. Nbcastings is a global manufacturer of die cast metal parts. We offer a comprehensive range of die casting services to meet a variety of needs and requirements. During the manufacturing process, molten metal is poured into a mold to create parts with high precision, intricate details, and a perfect fit. Die castings are popular in automotive, aerospace components, power equipment, lighting, firearms, and several other industries.
High Pressure (HPDC), Low Pressure (LPDC) and Gravity Feed Die Casting (GFDC) Services
Nbcastings uses the latest die casting machines to provide high quality, on-demand parts for a wide range of industries. Our products focus on three types of die casting: High Pressure (HPDC), Low Pressure (LPDC) and Gravity Feed Die Casting. These types can all produce parts with complex geometries, close tolerances and strong mechanical properties. These parts need to be as light as possible by maintaining thin wall sections of the casting. Depending on the specific requirements of the project, Nbcastings can provide advice on the most appropriate and cost-effective die casting method and process design.

Die Casting Advantages
Sand casting is favored by customers who need to efficiently produce the highest quality cast metal. The process is suitable for a wide range of applications and is favored by customers and sand casting suppliers.
- Suitable for low-cost, high-volume, fast production cycles
- Suitable for thin-walled products
- Repeatability - maintain uniform quality, appearance and dimensional accuracy
- High-quality parts with long service life
- Lower labor costs – less assembly required
- Design diversity – complex shapes, geometries, surface textures or gloss
Why Choose Nbcastings for Die Casting?
Quality Standards
Our quality standards have ISO certification, which means our components meet high standards, allowing us to optimize your costs and reduce risks.
Short Lead Times
Although production of parts through investment casting tends to be lower volume and slower than other manufacturing methods, we understand that delays have a significant impact on your business. Therefore, we are committed to on-time delivery, and our lead times are among the fastest in the industry.
A Comprehensive Approach
The investment casting process is a start-to-finish process, starting with our design advice to ensure parts are produced to the correct standard. Throughout the project we ensure quality, consistency and streamlined supplier management.
