When to Choose For Your Manufacturing Projects
Choosing between cold chamber die casting and hot chamber die casting depends mainly on the alloy type, product design requirements, production volume, and cost/efficiency expectations. Below is a clear guide — especially useful for die casting factories selecting process routes.
Cold Chamber Die Casting For Project
Cold chamber die casting is suitable for these high melting metal alloys, such as aluminum, copper, gold, silver and steel. Because these metal alloy can be molten with seperated furnace from the die casting machine, and require more heat energy to melt them, and these molten metal alloys have very high temperature(from 600℃~1800℃).Since the metal die castings are large size and heavy weigt, Forming the metal part needs longer time and low cooling, even through natural air cooling or lower cooling approches, avoid fast cooling causes cold shut and sudden shrankage lead to bend.
Based on Alloy Material
| Alloy | Recommended Process | Why |
|---|---|---|
| Zinc-Aluminum (ZA alloys) | Cold chamber (some) | Higher melting point, not suitable for hot chamber |
| Aluminum | Cold chamber only | High melting temp damages gooseneck |
| Brass / Copper | Cold chamber | Very high melting point & corrosive |
Applications
| Requirement | Choose |
|---|---|
| Large-sized castings, heavy chassis, bases and wheel | Cold chamber |
| High corrosion resistance at specific environments | cold chamber |
| High mechanical strength & structural parts | Cold chamber |
Hot Chamber Die Casting For Project
In the die casting, molten furnace is integrated with the machine. Feeding the metal material into pow, and melting metal material and overflow impurities and keep purified and steady temperature molten material for injection. Though gooseneck mechanism, The hydraulic piston pushes the molten metal into the preheated die. Then under high pressure the molten metal flow fills into the die fully, cooled and solidified, the die is opened, the desired cast part is ejected out of the die. So hot chamber die casting is ideal for low melting point metal, such as zinc, lead and tin alloys.
Choose Metal Alloy Materials

Cold Chamber Die Casting Process Guide
Some large size cast parts required for heavy industrial equipment components and countweight, die casting manufacturers often produce theseheavy weight die casting components with cold chamber die casting machine, similar with aluminum die casting process. The cold chamber die casting process runs the below steps one by one.
Step 1: Mold Preparation
The precise mold & die has a higher intial fabrication cost, and ensure a longer life time of it, and preheated and avoid cold shut and flow trace of cast part occurred. Die Release agent is sprayed after each cast cycle finished, and ensure the cast part ejected smoothly each time. Keep the halves of the mold is alignment with each other, and makes ejector pins eject the cast part from the core of the mold.
Step 2: Melting & Pouring
Melting these high melting points metal with high volume heat energy, and overflow the impurities within the metal, maintain the steady temperature molten metal in reservior. And have a sufficient preparation for pouring the molten metal. When molten metal is manually or automatically ladled, and poured into the cold chamber shot. This is mechanical action, replace labor operation, reduce some accidents for scald.
Step 3: Injection
The hydraulic or mechanical plunger forces the metal into the die cavity at high pressure, and fill the metal into the die fully quickly. These high melting points metal have a good fluidity, and forms high accuracy dimensions and fine surface finishing under high pressure. Pressure ensures strong integrated structure and fine surface of cast part, and minimizing post-process operations.
Step 4: Cooling & Ejection
The molten metal cools and solidifies inside the die when the metal is filled into the cavity of the die fully, The cold die casting machine starts water cooling system, cools the die, makes the metal inside the die solidifies in shorter time. The die opens, and ejector pins push out the casting part, and a cast cycle finished. The die close, proceed the next cast cycle.
Step 5: Trimming & Finishing
As-cast part require some post-processes for deburring. Depends on the specific requirements of process, the cast part may be machined. Secondary operations (machining, surface treatment) may be applied. Such as polishing, grinding, bead blastering and other trimming operations.
Overview Of Hot Chamber Die Casting
Hot Chambe Die Casting Process Guide
Molten Metal Supply
The furnace supply required temperature to melt the metal alloy and preparing storaged melton alloy. Preheating zinc alloy and maintain stable casting temperature. Zinc alloy melting point is 420 degrees or so, commonly the furnace melt the alloy with electricity power, it is environmental protection and hygiene. This melting reservior can overflow impurity inside molten zinc and purify zinc inside the vessel.
Injection of Molten Metal
The piston pushes the molten metal through the gooseneck mechanism and into the mold cavity. With High pressure (typically 1,000–10,000 psi) drive the good fluid melton zinc alloy fills every detail of the mold fully. During injection of molten zinc alloy, ensure integrated structure and fine surface finish of cast part, using the proper venting and gates setting to extrudize entrapped air, avoid the porosity defects of the part.
Cooling and Solidification
After the metal part cools and solidifies, The machine drive the mold open, and the part is ejected from the mold by usingejector pins. The cooling system should cool the casting part evenly, avoid the temperature shut down lead to shrinkage and warpping. Conduct real time monitoring data in casting process, ensure the casting process smooth running at repeative cycles.
Ejection of the Casting
After the metal part solidifies, The machine drive the mold open, and the part is ejected from the mold by using ejector pins quickly. To ensure the part seperate from the mold in time and without any stick residues on the cores and cavities of the mold, Draft angles strategy is planned. Exception for the above, spraying release agent is neccessary.
Cycle Production
The mold is lubricated, and the cycle begins again, allowing for high-speed, automated production. The hot chamber die casting can produce high quality zinc die casting parts repetively in short cycle. Every cycle cast needs a few seconds, mass production for zinc die casting components save more time and minimize the zinc material waste.
