Die Casting

Die casting is a metal casting process. Molds are usually made of higher strength alloys, which is somewhat similar to injection molding. Most die castings are iron free, such as zinc, copper, aluminum, magnesium, lead, tin and lead tin alloys and their alloys. Depending on the type of die casting, it is necessary to use cold chamber die casting machine or hot chamber die casting machine.
      The cost of casting process is generally only used for mass production. Die casting is especially suitable for manufacturing a large number of small and medium-sized castings, so die casting is the most widely used in various casting processes. Compared with other casting technologies, the surface of die casting is smoother and has higher dimensional consistency.

FAQ for sand casting service

FAQ guide for all questions on sand casting serivce , hope it help you settle your hesitation in cooperation.

1. What Is Investment Casting?

Investment casting, also known as precision casting, is an industrial lost wax manufacturing process for many metal components.

2. What Kind of Products Could be Made in Investment Casting?

Investment casting process is suitable for products less than 100kg, and it is flexible for product design, no matter how complex it is. So investment casting can make almost all the small products. For larger products, sand casting is preferred.

3. What Are the Benefits of Investment Casting?

There are lots of benefits of investment casting, such as affordable tooling cost, no quantity limitation, flexible design, a large selection of material specifications, etc. See more about the benefits of investment castings

4. What Type of Tooling is Required for Investment Casting?

A split aluminum tool or die is used to create a wax pattern, which is then coated with layers of stucco and ceramic material. Before pouring the alloy, wax will be first melted away, which is where the term “lost wax casting” originated. In other processes (forging, stamping, die casting), tooling is quite much more complex and expensive.

5. What General Tolerances can We Meet for An Investment Casting Part?

For lost wax investment castings, we can reach general tolerances CT7-CT8. And for smaller precision parts, CT5-CT6 can be available.

6. What Is the Typical Surface Finish of Investment Casting?

Good surface finish starts with the injection die and the production of a wax pattern with an excellent surface. Next, the first layer of ceramic applied to the pattern is designed to replicate extreme detail and create an interior mold surface that is very smooth and non-reactive when contacted by molten metal. As a result, surface finishes of Ra12.5-Ra6.3 are typical with some alloys producing smoother surfaces than others.

7. Is Small Quantity Acceptable for Investment Castings in Your foundry?

Yes, we do not have quantity requirements for investment castings, even if a trial order with small quantity, it is also acceptable. Besides, we can supply demands of large quantity order with annual capability of 8,000t.

Secondly,we are equipped with complete testing instruments, such as Spectrograph, Brinell & Rockwell hardness tester, Impect testing instrument, MT instrument, etc. Thirdly, sample will be provided before mass production. Also, for mass production, we will select some products randomly for testing. And even if there will be quality problem after delivery, we will also send replacements asap at our own costs or return parts of production payments to our customers directly.

9. Can Matson Metal Foundry Provide Machining Service After Investment Casting?

Even if investment casting can reach excellent tolerances, sometimes, for tighter dimensional tolerances, additional machining will be needed. So to supply finished products, we also have a mature machining production line.

10. What Is the Lead Time of Investment Castings?

12. What is Sand Casting?

Sand casting, it is also called sand molded casting, is a metal casting process that utilizes sand as the mold material. The expression “sand casting” can likewise allude to a product created through the sand casting process. In other words, the mold is made of compressed sand.

We can also define it as a manufacturing procedure where the liquid metal is filled the superfluous sand mold hole either by gravity or forcibly, where it hardens to frame the cavity shape. According to metal casting research, 60% of metal castings are produced through sand casting. This just goes to show how this method of producing metals is very popular across all the different industries.

13. Which type of sand is used for sand casting?

Can any sand be used for sand casting? The answer is a definite no. There are specific types of sand that can be used for the process.

Various types of sand are used for casting prospects. The perfect sand should hold up under mechanical pressure yet additionally be sufficiently porous to permit gasses and steam to escape during sand casting.

The picked sand should likewise join perfect flowability levels for your application. Its moisture content ought to be correctly picked. Sand with extremely low moisture content can cause the mold to break. On the other hand, the sand with high moisture content can cause saturation of steam in the mold. Sand grain shape and size likewise influence mold quality, just as the sand’s capacity to withstand high temperature (otherwise called obstinate quality). This can cause the mold to collapse when subjected to extreme pressure.
