In the field of metal parts manufacturing, casting is one of the most basic and critical processes. As a professional casting company, JC Casting has been deeply engaged in die casting, sand casting and investment casting for many years. It provides customers with high-quality casting solutions. This article will introduce the differences and connections between these three casting processes in detail to help you better choose the appropriate casting method.
Die Casting
1. Process Overview
Die casting is a casting method that injects molten metal into a steel mold (die casting mold) under high pressure. Since the mold can be reused, die casting is particularly suitable for mass production. Common die casting materials include aluminum alloys, zinc alloys, and magnesium alloys.
2. Process characteristics
- High precision: Die castings have high dimensional accuracy. Good surface finish. Usually no additional machining is required.
- High production efficiency: Suitable for mass production. Short single-piece production cycle.
- Strong thin-wall capability: Can produce complex thin-walled parts. Minimum wall thickness can reach 0.5mm.
- High mold cost: Die casting mold manufacturing cycle is long. The initial investment is large, suitable for long-term stable orders.
3. Applicable scenarios
Die casting is widely used in automotive parts, 3C electronics, home appliances, hardware and other fields. For example, automobile engine housing, laptop computer housing.
JC Casting Tips: If you need large quantities and high-precision metal parts. Die casting is an ideal choice. We have advanced die casting equipment and rich experience to ensure stable product quality.
Sand Casting
1. Process Overview
Sand casting is the most traditional casting method. Sand molds are used as molds. It is suitable for various metal materials, such as cast iron, cast steel, aluminum alloy, etc. Sand molds can be wet sand, resin sand or water glass sand, etc.
2. Process characteristics
- Wide range of applications: It is suitable for almost all metal materials. It is especially suitable for large castings.
- Low cost: The mold is simple to make. It is suitable for small batch or single piece production.
- High flexibility: It can produce complex shapes and large parts. Such as machine tool beds, valve housings.
- High surface roughness: Compared with die casting and precision casting. Sand castings have lower surface accuracy. Subsequent processing is usually required.
3. Applicable scenarios
Sand casting is often used in heavy machinery, ships, mining equipment, pipe fittings and other fields. For example, large gearboxes, pump bodies, building structures.
JC Casting Tips: If you need to produce large or single-piece custom castings. Sand casting is a cost-effective choice. We provide a variety of sand casting solutions to meet different customer needs.
Investment Casting
1. Process Overview
Investment casting, also known as lost wax casting, is a high-precision casting process. Its core steps include making wax molds, coating multiple layers of refractory materials, and pouring metal after melting the lost wax mold.
2. Process Features
- Ultra-high precision: high dimensional accuracy of castings. Good surface finish. Close to machining level.
- Strong ability to handle complex structures: extremely complex parts can be produced. Such as turbine blades and artistic castings.
- Wide selection of materials: suitable for difficult materials such as stainless steel, high-temperature alloys, and titanium alloys.
- High cost: due to the complex process. Precision casting is suitable for small and medium-sized batches of high-value-added products.
3. Applicable scenarios
Investment casting is widely used in aerospace, medical equipment, precision instruments, jewelry and other fields. For example, aircraft engine blades and medical device implants.
JC Casting Tips: If you have extremely high requirements for the precision and surface quality of castings, investment casting is the best choice. We have a mature precision casting production line to ensure that the products meet strict standards.
Comparison of three casting processes
How to choose the right casting process?
- Large-volume, high-precision, thin-walled parts → Die casting
- Large-scale, single-piece or small-volume, low-cost requirements → Sand casting
- Ultra-high precision, complex structure, high value-added parts → Investment casting
JC Casting is a professional casting service provider. We can recommend the best process according to your specific needs. And provide full support from design to finished product.
Conclusion
Die casting, sand casting and investment casting each have their own advantages. The process you choose depends on product requirements, materials, budget and other factors. No matter which casting solution you need, JC Casting can provide professional technical support and high-quality casting products. We have our own factory and CNC machine tools to ensure that every casting meets customer expectations.
