Sand casting and die casting are the two most widely used casting processes. Comparing the two according to information such as material, casting complexity, performance requirements, order size, etc., and choosing the right process can efficiently complete the order and save more costs. This article will make a detailed comparison of the two from the definition, history, molds used, castable materials, processes, costs, and the performance of the corresponding castings, whether heat treatment can be performed, and applications so that you can choose a more suitable process and find a supplier that suits you.
Sand casting is a process in which sand is bonded with a binder to make a mold with a cavity inside. Liquid metal flows into the cavity along the gate under the action of gravity, and parts are obtained after cooling and finishing.
Die casting is a process in which a special metal material is used to make a metal mold and liquid metal is injected into the cavity under the action of high pressure, and parts with higher precision are obtained after cooling.
Sand casting has a history of thousands of years. In the earliest days, the binder was clay and the sand was silica sand, which is still in use today. Now, a variety of binders such as natural resin, synthetic resin, silica sol, water glass, quartz sand, corundum sand, limestone sand, zircon sand, chromite sand, etc. have been developed. Sand casting is still one of the most widely used casting processes in casting.
Die casting began in 1838. It was originally used to make molds for movable type printing. At that time, the main material was lead. In 1966, General Motors invented the precision die-casting process.
Both processes have different classification methods and names after classification. Below we will compare the two processes in terms of types.
The classification method of sand casting is mainly based on the binder and the precision of the casting.
is a process in which clay containing a certain amount of water is mixed with sand as a binder to make a mold and complete the casting.
is a process in which synthetic resin or natural resin is mixed with sand as a binder to make a mold. The precision of castings produced by this process is very high.
water glass is an aqueous solution of polysilicate. It is used as a binder to make a mold. The precision of parts produced by water glass casting is also relatively high.
The classification of die casting is mainly based on the pressure during injection and the type of die casting machine.
the die casting pressure is about 20-100 kPa (2.9-14.5 psi), rather than gravity to fill the mold.
is a process of injecting liquid metal into the cavity at a speed of 30-80m/s at a pressure of 40-120MPa to complete the production of castings.
is more suitable for producing low-melting-point non-ferrous alloy parts such as zinc and lead.
is suitable for die casting aluminum, zinc, lead, and other low-melting-point metals.
The two casting molds have huge differences due to the process. The following will compare them from the two aspects of material and production.
are mostly produced with high-temperature and high-pressure resistant hot working die steel H13. The mold components include fixed mold and movable mold, guide parts, ejection structure, lateral core pulling mechanism, overflow system, and supporting parts.
are made of the above sand and a binder to make a sand mold and a sand core and assemble it into a casting mold. When making the sand mold, a model of the casting will be used. The material of this model can be wood, metal, plastic, etc. The mold consists of two parts: the sand mold and the sand core.
The manufacturing of die-casting molds is very complicated, but a set of molds can be used for a very long time under correct use and maintenance. It will be very cost-effective if the cost is calculated from a long-term perspective, but it will be very uneconomical if a mold is produced for a small batch of orders.
The manufacturing of sand casting molds will be much simpler, but each mold will be disassembled after the production is completed through the sand dropping process and then processed and reassembled.
There are two types of casting manufacturing processes: manual molding and mechanical molding:
Mechanical molding can be automated, which can greatly improve the production efficiency of castings. Its production efficiency is too high, so it is more suitable for the production of large batch orders.
Manual molding is more suitable for the production of small batch orders or large batch orders with long delivery cycles.
Both processes cast liquid metal into metal castings with specific shapes and properties, but they are very different in details. Let's compare their processes below.
1. Manufacture casting models according to drawings or samples.
2. Split the model into a part for making sand molds and a part for making sand cores.
3. Manufacture sand molds and sand cores separately.
4. Assemble the sand mold and sand core to obtain a casting with a gate.
5. Heat the metal to a molten state.
6. Pour the molten metal into the casting along the gate.
7. After cooling, drop the sand and clean it.
8. Perform finishing on the casting such as machining, heat treatment, surface treatment, etc.
9. Get the final casting
1. Manufacture die casting molds according to drawings or samples.
2. Install the die casting mold on the die casting machine.
3. Overall debugging of the die casting machine.
4. Preheat the die casting machine.
5. Heat the metal to a molten state.
6. Close the mold.
7. Press the metal into the cavity under high pressure.
8. Cooling post-processing.
9. Perform finishing on the casting, such as machining and surface treatment.
10. Get the final casting.
Die casting requires a die casting machine for production. Sand casting does not need it, but if sand casting is equipped with an automatic pouring machine, it will have higher production efficiency.
Die casting requires high pressure to complete the cavity filling, while sand casting only needs gravity.
The die casting process is more complicated, while sand casting is simpler.
The two castings have their own suitable materials.
Sand casting can be used to produce castings made of metals such as iron, steel, copper, aluminum, and zinc.
Die casting can be used to produce die castings made of die casting aluminum ADC10, ADC12, ADC3, A380, A383, A360 and other die casting aluminum alloys and zinc alloys such as low melting point metals.
The process is for the final product. The purpose of our comparison is to select which one is more suitable for your product. To this end, we can choose from four aspects: product tolerance, structure, surface quality, and when heat treatment is needed.
The dimensions of die castings are more accurate, and even some castings with strict requirements can be used directly. Of course, if it is a die casting that requires a tolerance of less than 1μm, it still needs to be processed. When designing the mold for the casting that needs to be processed, the machining allowance needs to be calculated.
Die casting can complete very complex castings in one go.
The relative surface of the die casting is smooth. Basically, no surface processing is required. If the surface requirements are strict, polishing is required.
Die castings can be subjected to surface treatments such as powder spraying, electrophoresis, and electroplating, but cannot be anodized.
Die castings cannot be heat treated. This is because there are high-pressure pores inside. After heating, the casting becomes soft and the pores expand, which will cause the casting to deform or damage.
The dimensions of castings are not as precise as die castings, so for castings with strict tolerance requirements, it is necessary to directly reserve machining allowances when designing the mold to facilitate CNC machining.
Some sand casting processes can only complete castings with relatively simple structures. Water glass sand casting, resin sand casting and coated sand casting can produce more complex castings.
The surface of sand castings is not as smooth as that of die castings. Compared with the classification of sand casting itself, the surface roughness of castings is coated sand casting ≈ resin sand casting > water glass sand casting > clay sand casting. Sand castings are often used for castings with less stringent surface requirements.
Sand castings can be heat treated to increase their performance. Common methods are:
Annealing:
Normalizing:
Quenching:
Homogenization treatment:
Tempering:
Solution treatment:
Precipitation hardening:
Stress relief:
Dehydrogenation treatment:

Die casting is mainly used to produce metal castings with low melting points, such as aluminum, magnesium, zinc, lead, etc. Sand casting can be used to produce metal castings of most materials, such as aluminum, iron, copper, steel, etc. The following is a comparison of their applications in various industries:
Automobile manufacturing is one of the largest application areas of die casting. Since automotive parts require high strength, durability and light weight, die-cast aluminum alloy and magnesium alloy parts are widely used in key components such as engines, gearbox housings, radiators, and wheels.
The die casting process is used to produce the housings and internal parts of products such as mobile phones, laptops, and household appliances. Magnesium alloys are widely used in the housings of electronic devices for their light weight, heat dissipation and strength. Die casting is also used for small motor housings and connectors in electrical appliances to ensure the accuracy and performance of these parts.
The aerospace industry requires high-strength, low-weight materials to ensure the performance and safety of aircraft. Die-cast aluminum and magnesium alloys are used to manufacture aircraft structural components and engine components. The application of die casting technology in aerospace can help reduce material waste while ensuring the accuracy and consistency of complex components.
Die casting is widely used in the medical device industry to manufacture precision instrument housings and structural components inside medical devices. The corrosion resistance, strength and surface quality of the material make it indispensable in medical devices.
Die casting is also widely used in the manufacture of daily consumer products such as door locks, kitchenware, lamps, furniture accessories, etc. Die casting metal products are beautiful in appearance, good in feel and durable, making them competitive in the consumer goods market.
Die castings are also widely used in the housings and internal transmission structures of power tools due to their precision and robustness. High pressure casting can meet the requirements of power tools for precision, strength and impact resistance.
The lighting industry also uses die casting to produce lamp housings and related components. Die casting aluminum alloys play an important role in such applications because lamps require good heat dissipation and durability.
can produce large-sized, complex-shaped and multi-material castings, and is widely used in many industries. The following are the main application areas of sand casting:
In the automotive industry, sand casting is used to produce large and complex metal parts such as engine blocks, cylinder heads, intake manifolds, exhaust manifolds, etc. These parts need to withstand high temperatures and pressures, so cast iron or cast aluminum materials are usually used.
Sand casting is widely used to manufacture parts for heavy machinery, such as construction equipment, mining equipment, and agricultural machinery. These parts are usually large in size, complex in shape, and need to withstand high-load working conditions, so the sand casting process is very suitable.
Sand casting is widely used in the pump and valve industry, especially large industrial pump housings and complex valve bodies. Sand casting can accurately cast the complex internal channels required by pumps and valves to ensure that fluids can pass smoothly.
Sand casting is also used in the aerospace field, mainly for the manufacture of aircraft engine housings, turbine components and other complex structural parts. Sand casting can handle high-temperature resistant alloys and other special materials to meet the high material performance requirements of the aerospace industry.
The shipbuilding industry uses sand casting technology extensively to produce large parts such as hull parts, propellers, bearing seats and valves. Sand casting can produce corrosion-resistant and wear-resistant metal parts, ensuring that ships can operate for a long time in harsh marine environments.
Sand casting is widely used in the manufacture of power generation equipment, especially large components in thermal power generation and nuclear power plants. These components require high heat resistance, pressure resistance and complex internal structures, and the sand casting process can provide a reliable solution.
Sand casting is used in the construction industry to produce various structural components and decorative parts. Common applications include stair supports, railings, bridge structural components, etc. The strength and durability of sand-cast cast iron and cast steel products are very suitable for the needs of the construction industry.
Sand casting is widely used in the field of artistic casting to make large sculptures, monuments and artistic decorative pieces. The sand casting process can capture fine details and allow artists to create complex and durable metal works.
Cost is one of the main factors we consider when choosing a process. And the calculation of cost is very complicated. Below we mainly compare the costs of the two castings from the two aspects of mold making and production.
The number of castings is the X-axis and the mold is the Y-axis. As the value of X increases, the average cost of die casting molds to die castings will become lower and lower until it reaches a stable value. Because in production, there is also a part of the cost of mold maintenance.
Sand casting molds have always been in a stable state of low cost.
Die casting production has a long start-up period. If a small batch order is produced, this part of the cost will be abnormally high. Therefore, die casting technology will only be more suitable for large-scale production.
Sand casting is more flexible because its casting can be done by hand. Regardless of the size of the order, the production cost is controllable.
Die casting is suitable for completing the following orders.
Low melting point materials: die casting aluminum, magnesium alloy, zinc alloy, lead alloy, etc.
Castings with high precision requirements and no need for heat treatment.
Orders with a large number of single castings.
Sand casting is suitable for producing almost all casting orders.
Choosing a suitable casting service supplier is crucial to ensure project quality, efficiency and cost control. HULK Metal, a long-established service provider that has provided services to customers around the world for more than 20 years, recommends that you consider the following 8 aspects when choosing a casting service provider.
They can help you choose a more suitable process to complete the order
First, clarify the type of casting service you need.

A supplier with a complete supply chain is often closer to the factory. They will give you more effective reports when you want to know the progress of the order. And suppliers with a complete supply chain can often help you control costs from the entire order process. You can complete the order with less money.
The degree of control they have over price and cost control
Although price is an important consideration, it cannot be at the expense of quality. Cost factors to consider include:
Different suppliers may have different pricing for the same material, especially in terms of material procurement channels. Excellent suppliers will have multiple closely cooperating material factories to deal with some emergencies.
The complexity of the casting process, the degree of automation, etc. will affect the cost. We will optimize the production process and use more advanced equipment and experienced workers to complete the order, which can greatly save production costs.
Especially when purchasing overseas, transportation and import costs are also part of the budget. With our own logistics team, we can help you save a lot of money from the factory to the destination port. Our freight consulting team can also help you save time and money looking for a freight forwarder.
Of course, you can compare prices from multiple parties to ensure that the price is reasonable and transparent.
Their communication timeliness, effectiveness and cooperative attitude:
Timely and effective communication can ensure that orders are completed more smoothly and effectively. The service time we provide can be said to be the longest in the industry. It starts at 6 am and ends at 11 pm China time. This can cover the working hours of most countries as much as possible and deal with customer problems.
Super high cooperation is a must-have advantage for an excellent supplier. They will actively respond to customer requirements and meet customer requirements as much as possible.
They must provide quality assurance and after-sales service
Quality assurance is a must-have service that a good supplier will provide you. Our quality control center will attach a complete test report to each order and provide return, exchange and replenishment services for every product with quality problems.

Jaw Rope Puller Parameter
Jaw Rope Puller has passed strict sampling inspection before leaving the factory. Each batch of goods can meet the use requirements. We have a complete supply chain to provide you with more thoughtful services and higher quality products.
Jaw Rope Puller is a tool designed to pull Copper Cable, Cover Cable, Bare Aluminum Cable, ACSR, ACSS, AAC, ABC, Bare Cu Cable, Guy Wire, Wire Rope, Barbed Wire, Trolley Wire, etc. to a specific location. One end of the Jaw Rope Puller is used to connect to the tensile machine, and the other end is connected to the rope. As the tensile machine is started, the cable will gradually tighten or be pulled out from one end of the cable duct.
There are two designs for the jaws of the Jaw Rope Puller terminal jaws:
One is that the fixed jaw is straight and smooth, and the movable jaw is curved with longer anti-skid teeth. This type has a smaller contact area with the cable than the other and is more suitable for tightening harder metal ropes.
The other type has both the fixed jaw and the movable jaw straight and horizontal, and both are filled with shallow anti-skid teeth. This type has a larger contact surface with the cable, which can provide stronger friction while protecting the outer skin of the rope. It is suitable for more rope operation scenarios.
Some types of Jaw Rope Pullers will have side baffles, which are used to prevent the cable from detaching from the side of the Jaw Rope Puller due to force changes when tightening, causing accidents.
They all use springs to achieve automatic merging after opening. We use high-elastic alloy springs that can be used repeatedly for hundreds of times.
Jaw Rope Puller Supplied by HULK Metal is made of high-performance alloy steel through hot die forging. It has stronger performance.
Most of its parts are produced by hot die forging, the baffles are laser cut, and the parts are assembled by our assembly line after galvanizing.
Its surface treatment is electrogalvanizing. Its average coating thickness is 5μm.
Our Jaw Wire Puller has two types of jaws to accommodate a wider variety of wires. Some types also have side panels to prevent the wire from slipping out from the side during tensioning. You can choose a more suitable one based on factors such as wire type, wire diameter, and usage scenario.
HULK Metal can provide you with a variety of jaw grip pullers. You can choose a more suitable style according to the Guy Wire diameter, tension and other parameters, as well as the contact surface damage requirements.
