Our Die Casting Services Process
Metal Casting Services by Glproto
When we first started delivering precision prototypes to customers, one question kept coming up: “Can you also help us with small-batch metal casting?”
At that time, finding reliable low-volume die casting suppliers was a real challenge. Large casting factories were not interested in small production runs, while smaller workshops couldn’t meet our strict quality standards. Every project became a balancing act between quality, lead time, and cost.
Instead of giving up, we decided to take on the challenge ourselves. We began searching for capable partners who shared our commitment to precision and reliability. After two years of continuous testing, qualification, and collaboration, we built strong partnerships with medium-sized casting facilities that meet our exacting standards.
Today, we proudly offer high-quality Metal Die Casting Services—covering aluminum, magnesium, and zinc high-pressure die casting, as well as investment casting in brass and various steels. Whether you need prototypes or low-volume production, we provide a reliable solution with consistent quality, quick lead times, and expert technical support.
With us, small-batch metal casting is no longer difficult—it’s efficient, precise, and dependable.
Why Use Glproto for Metal Casting
It might seem counterintuitive to choose a rapid prototyping firm for metal casting services, yet we deliver compelling advantages:

What is Die Casting?
Die casting injects molten non-ferrous metals like aluminum or zinc into steel molds under high pressure for precise, complex parts with smooth finishes. Glproto’s hot/cold-chamber process uses CNC dies, melting, injection, cooling, and minimal post-machining. We deliver cost-saving, reliable prototypes to high-volume runs, boosting efficiency for automotive and electronics.
Our flexibility accommodates projects from prototyping to large batches.
FAQ's
What is the minimum order quantity (MOQ) for your Custom Die Casting Services?
Our custom die casting services are highly flexible. While the process is optimized for high-volume production to maximize cost savings, we can accommodate smaller production runs starting from approximately 50 to 100 units, and often support initial low-volume prototyping needs.
Which materials do you commonly use in the Pressure Die Casting process?
We primarily specialize in non-ferrous metals due to their excellent casting properties. Our most common materials include Aluminum alloys (such as A380 and ADC12), Zinc alloys (like Zamak series), and Magnesium alloys. These materials offer a balance of strength, lightweight properties, and corrosion resistance.
What dimensional tolerances can I expect from your die cast parts?
Our die casting tolerance standards adhere to strict industry guidelines, typically meeting standards like ISO 8062 or specific client requirements. While standard tolerances are common, we can achieve very tight dimensional accuracy on key features through specialized tooling and subsequent CNC machining if necessary.
What is the difference between Hot Chamber and Cold Chamber Die Casting?
Hot chamber die casting is used for low-melting point alloys (like Zinc and Magnesium), where the melting pot is integrated with the machine. Cold chamber die casting is used for high-melting point alloys (like Aluminum), requiring the molten metal to be transferred externally, offering greater versatility for different metal alloys.
Can you assist with Design for Manufacturability (DFM) for my die casting project?
Absolutely. Our engineers perform critical DFM analysis early in the process. We advise on wall thickness, parting lines, draft angles, and feature placement to optimize the design, which helps minimize casting defects and reduce the overall cost per part in high-volume production.
What is the typical lifespan or durability of a die casting tool (mold)?
The lifespan of a die casting mold depends on the alloy used (Aluminum is harder on tooling than Zinc). Typically, a well-maintained pressure die casting tool designed for Aluminum can produce anywhere from 50,000 to 150,000 “shots,” and zinc die casting molds often last for millions of cycles.
What makes die casting more cost-effective than CNC machining for high volumes?
Die casting uses durable, reusable hardened steel dies. While tooling costs are higher initially, the fast cycle time and low cost per part quickly offset the expense when manufacturing thousands of identical metal parts. CNC machining remains better for low-volume prototypes and intricate finishing.
What are the common applications for parts produced via die casting?
Die cast components are widely used across various industries. Common applications include automotive parts (engine components, transmission housings), consumer electronics casings, medical devices, hardware, and structural elements where strength, uniform density, and complex geometry are essential.
Do you provide secondary finishing and post-machining services for die cast components?
Yes. Although die cast parts typically feature smooth surfaces, we offer comprehensive finishing. This includes CNC secondary machining (drilling, tapping, milling) for critical features, along with various surface finishing treatments such as powder coating, plating, and anodizing to enhance aesthetics and durability.
