Investment Casting VS Die Casting

Investment Casting VS Die Casting

  Investment casting and die casting are the two major types of casting. Investment casting methods is injects wax into an aluminum cavity. Die casting is the process in which molten metal is forced into a mold cavity with high pressure. Each of the casting method has their own advantages and disadvantages.They are used to make different kinds of products.So how to compares investment casting with die casting or which one is better for your choosing?

Investment Casting

Investment casting is a precision casting process using lost wax method to make components in metal cast alloys. Investment casting manufacturers use a product wax pattern to make a mold. Then they dip the wax pattern into a refractory slurry. To made of materials like plaster of silica or sillimanite and silica to form the mold. After dipping the wax into the slurry, manufacturers heat the pattern to melt and remove the wax. After harden the slurry binders. They then pour molten metal into the mold and allow it to cool. The mold or pattern of investment casting is made by aluminum. Then dipping the tree assembly into refractory slurry to form a ceramic shell. Finally pouring molten metal into the shell by spruce gate and cooling for solid casting blanks.

Advantages and Disadvantages of Investment Casting 

Advantages of Investment casting Disadvantages of Investment casting 
Cast ferrous and non-ferrous materialsExpensive Cost than sand casting
Smooth surface finishes,reducing machining and finishingLonger Lead time
Investment casting in thin walled parts with complex shapes
Very accurate,Create products with precise dimensions even net shape

Die Casting

  Die casting is a metal casting process. It is characterized by the use of a mold cavity to apply high pressure to the molten metal.Molds are usually machined from higher strength alloys. Some of which are similar to injection molding.Most die castings are iron-free. For example: zinc, copper, aluminum, magnesium, lead, tin, and lead-tin alloys and alloys.As per the type of die casting, a cold chamber die casting machine or a hot chamber die casting machine is required.Casting equipment and molds cost are expensive. So the die casting process is generally only used to mass produce a large number of products.It is easy to make die-cast parts. This requires only four main steps, and the cost per item is very low.

Advantages and Disadvantages of Die Casting 

Advantages of Die CastingDisadvantages of Die Casting
Good product qualityCastings are prone to generate air holes and cannot be heat treated
High productivityDie casting is difficult for complex concave castings
Excellent economic effectHigh melting point alloys (such as copper, ferrous metals), die casting type has a shorter life
Not suitable for small batch production. Because of high manufacturing cost

The Differences between Investment Casting and Die Casting

  Investment Casting is a metal thermal processing process. Die casting is one of them. The main differences between of them are as follows:

  1–Definition is different

  Casting is a metal thermal processing process in which a liquid metal is cast into a casting cavity adapted to the shape of the part. And after cooling and solidifying, a method of obtaining a part or a blank.Die casting is a metal casting process. It is a precision casting method that uses high pressure to force the metal to be hydraulically poured into a complex metal mold.

  2–Range is different

  Casting mainly includes sand casting and special casting. Sand casting includes wet sand type, dry sand type and chemical hardening sand type. Special casting includes investment casting, metal casting, pressure casting, low pressure casting, centrifugal casting, etc. Die casting is only pressure casting.

  3–Characteristics is different

  A common feature of casting is heat treatment. The high pressure and high speed filling die casting is the two characteristics of die casting.

  4 — Cost is different:

Investment casting is a manual process that produces excellent dimensions and good surface finish. So it seems to be a costly casting method. Investment casting is also the most likely technique to reduce or avoid secondary processing.It can reduce time and money. Die casting costs are higher because of its high processing costs and sometimes even post-processing operations on finished parts. So, for a large number of orders, die casting is more cost effective.

  5–Surface treatment is different:

In all casting techniques, the surface finish of investment casting is always the best. Although die casting produces a good surface finish, more processing is often required to bring the product to its final state. But, we can improve the surface finish of investment casting and die casting through secondary processing and other surface treatment methods.

So depends on your requirements of products,you can choose the nest casting method. If the material is steel or iron,small product with complex shape,Investment casting is the best choice. If huge quantity, and the material is aluminum or zinc, the die casting will be your right option.If you have any inquiry about Investment Casting and Die Casting,leave a message,you will get an immediately reply.

  1. Hiya! I know this is kinda off topic but I’d figured I’d ask.
    Would you be interested in trading links or maybe guest writing a blog post or vice-versa?

    My site covers a lot of the same subjects as yours and I think we could greatly benefit from each other.
    If you might be interested feel free to send me an email.
    I look forward to hearing from you! Superb blog by
    the way!

  2. Healthcare, health-care, or health care is the upkeep or improvement of wellness using the prevention, medical diagnosis, therapy, recuperation, or treatment of disease, disease, injury, and also various other physical and mental disabilities in individuals. Health care is supplied by wellness professionals in allied wellness areas. Physicians and doctor affiliates are a part of these health and wellness professionals. Dental care, pharmacy, midwifery, nursing, medication, optometry, audiology, psychology, occupational therapy, physical treatment, athletic training as well as other health and wellness occupations are all part of healthcare. It includes work done in offering primary care, additional care, and tertiary treatment, as well as in public health.

    Accessibility to health care might vary throughout nations, areas, as well as individuals, influenced by social as well as economic problems along with health and wellness policies. Giving health care solutions implies “the timely use individual health services to achieve the very best feasible health results”. [2] Elements to take into consideration in regards to healthcare gain access to include economic constraints (such as insurance policy protection), geographical obstacles (such as additional transport prices, possibility to take paid time off of job to utilize such services), and also personal constraints ( absence of ability to communicate with doctor, inadequate health literacy, reduced earnings). [3] Limitations to healthcare solutions affects adversely the use of clinical services, the effectiveness of treatments, and also general outcome ( health, mortality prices).

    Health care systems are companies established to satisfy the wellness needs of targeted populaces. According to the Globe Health And Wellness Company ( THAT), a well-functioning healthcare system needs a funding system, a well-trained as well as properly paid labor force, reputable details on which to base decisions and policies, and also well maintained health facilities to deliver top quality medicines as well as modern technologies. [4]
    An effective healthcare system can add to a significant part of a nation’s economic situation, development, and industrialization. Healthcare is conventionally considered as an essential factor in promoting the general physical and also psychological wellness and also wellness of individuals around the world. An example of this was the worldwide elimination of smallpox in 1980, proclaimed by the WHO as the initial illness in human background to be entirely removed by purposeful healthcare interventions.
