Compare High pressure die casting to Other Manufacturing Processes
Why Use Die Casting in aluminum:

Forgings
Compared with forgings, die casting can be more complex in shape and have shapes not forgeable, can have thinner sections, be held to closer dimensions, and have coring not feasible in forging.

Plastic Injection moldings
Compared with plastic injection moldings, die casting are stronger, stiffer, more stable dimensionally, more heat resistant, and are far superior to plastics on a properties/coat basis. They help prevent radio frequency and electromagnetic emissions. For chrome plating, die castings are much superior to plastics. Die castings have a high degree permanence under load compared to plastics, are completely resistant to ultra-violet rays, weathering, and stress-cracking in the presence of various reagents. Manufacturing cycles for producing die castings are much faster than for injection moldings.

Extrusions
Compared to extrusions, die casting can be produced faster and more net shape. Features and depressions on the sides, tops and bottoms can be created in one operation. There is less waste using die casting than extrusion. Holes can be cast in place to save additional machining cost.

Stampings
Compared with stampings, one die casting can often replac several parts. Die casting frequently require fewer assembly operations, can be held within closer dimensional limits, can have almost any desired variation in section thickness, involve less waste in scrap, and are producible in more complex shapes. Die castings can be made in many shapes not producible in stamped form.

Screw Machine Parts
Compared with screw machine products, die castings are produced more rapidly, involve much less waste in scrap, can be made into shapes that are difficult or impossible to produce from bar or tubular stock, and may require fewer operations.

Sand castings
Compared with sand castings, die castings require much less machining, can be made with thinner walls, can have all or nearly all holes cored to size, can be held within much closer dimensional limits, and are produced more rapidly in dies which make thousands of die castings without replacement. Die castings do not require new cores for each casting, are easily provided with inserts die cast in place, have smoother surfaces and involve much less labor cost per casting.

Permanent mold castings
Compared with permanent mold castings, die castings can be made to closer dimensional limits and with thinner sections and holes can be cored to near net shape. Die castings are produced at higher rates with less manual labor, have smoother surfaces, and usually cost less per die casting.

高压压铸与其他制造工艺的比较
为什么采用压铸铝：

锻件
与锻件、压铸形状更复杂的形状，有没有可能有较薄的部分，被认为更接近的尺寸，并取心不可行的锻造。

塑料注射成型
塑料注射成型相比，铸造更强，更硬，更稳定的尺寸，更耐热，而且远远优于塑料在性能/外套基础。它们有助于防止无线电频率和电磁辐射。镀铬，压铸件远远优于塑料。压铸件与塑料相比在负载下具有高度持久性，在各种试剂的存在下完全抵抗紫外线、风化和应力开裂。生产铸件的制造周期比注射成型。

型材
相对于型材，压铸可以产生更快、更净形。在一个操作中可以创建边、顶和底的特征和凹陷。使用压铸比挤出少浪费。孔可以铸造到位，以节省额外的加工成本。

冲压件
与冲压件，压铸件往往能代替一部分。压铸经常需要更少的装配操作，可以在靠近的空间限制，可以几乎任何所需的变化的截面厚度，包括废品废料少，是更复杂的形状，可。压铸件可在许多形状上形成不可了。

螺杆机配件
与螺丝机产品相比，压铸件生产更迅速，涉及更少的废料废料，可以制成形状，难以或不可能生产从酒吧或管状股票，并可能需要更少的操作。

砂型铸件
与砂型铸件相比，压铸件需要较少的加工，可以用较薄的壁，可以有所有或几乎所有的孔芯尺寸，可以保持在更高的尺寸范围内，并更迅速地生产的模具，使数以千计的压铸没有更换。压铸件不需要新的核心为每个铸造，很容易提供镶件压铸到位，有光滑的表面和涉及少得多的劳动力成本每铸造。

永久模铸件
与永久型铸件相比，压铸件可进行更接近尺寸的限制，并用较薄的部分和孔可以被核心接近净形状。压铸件的生产率较高，体力劳动少，表面光滑，通常成本低于每压铸。
