Metal Casting Services

The metal casting services is the process of injecting molten metal into the cavity mold of the product under design, and the metal solution is cooled and solidified to create metal casting parts. According to the form of the mold, it can be divided into: metal sand casting, metal investment casting, and metal die casting.

This is an “additive” metal forming process, which is different from other precision machining that uses metal plates or bars. Metal casting parts have very high economic benefits and low-cost advantages, and can quickly obtain the expected part shape, which is suitable for Used for all metal materials.

Metal Casting Services ability

It is usually a process in which low melting point materials such as wax, plastic foam, and 3D printing are used to create the shape of the product. Through the steps of shell making, dewaxing, drying, casting, and cooling, the liquid metal material is formed into the structure of the target product.
This is an ancient casting method. Through modern industrial progress, we can achieve very accurate customer product design, economical and efficient. It is one of the widely used metal casting processes.

The liquid metal material is injected into the product metal casting molds through high pressure. After a few seconds, the cooled product is ejected to complete the product manufacturing process.
Although the cavity mold requires a relatively high investment, in the mass production process, the cost of the product will be greatly reduced, and a very ideal smooth surface and precise shape structure will be obtained. It is the best for large quantities of aluminum, magnesium, zinc and other alloy products. 

The widely used metal casting process involves mixing special sand and resin and wrapping metal (usually aluminum or wood) cavity metal casting molds to obtain the outer and inner cavities of the product with sand as the main body, and inject liquid metal materials Inside the cavity, the cast product is obtained after cooling. The sand casting process has few restrictions on materials, and the surface is not as beautiful and smooth as investment casting.

Mulan MFG is a professional metal casting manufacturer, rich metal casting experience and reasonable use of metal casting knowledge to solve quality problems in different situations.

When the metal solution is cooled and solidified in the mold, more outlets and channels are needed to remove excess gas, so that the metal casting solution can completely fill the mold cavity, but unreasonable channel setting or poor mold permeability will cause gas Trapped inside the metal casting parts, resulting in a lack of material.

Such as:

  • pinholes,
  • pores,
  • openings

The metal casting solution shrinks during the cooling process. This is a normal metal casting performance. Usually metal
Casting supplier reasonably sets the metal casting molds after calculation, but the temperature of the metal solution is too high or the mold runner is unreasonable, resulting in uneven solidification, and uneven material shrinkage will cause devastating quality defects to metal casting parts. Such as: pores or deformation, or even change the internal pressure of the material.

  • Open shrinkage defect
  • closed shrinkage defect
  • deformed shrinkage defect

When authorizing china metal casting foundry to run your casting parts manufacturing tasks, please don’t be too concerned about the cost of metal casting molds. Molds made of low-grade materials will often experience wear and other damage, which has a huge impact on the quality of casting parts. It will waste a lot of your time cost and mold cost. As the core technology of metal casting supplier, mold cannot be measured by money. There are many ways to manufacture low-cost molds, but high-quality molds require inspection and technology.

  • Poor processing
  • Poor heat treatment
  • Unreasonable runner
  • Low-quality materials
  • Short mold life

How to make high-quality casting mold solutions.

In many years of production experience, we have found that many metal casting manufacturer use metal materials after multiple castings for melting. These materials are not pure, and the residue inside is not filtered, and the residue will be embedded in the product during the casting process. It is a low-level error to cause a honeycomb or spongy appearance. And impure metal solution will affect the melting point and fluidity, and it can also cause different cracks and defects on the surface of casting parts.

Mulan MFG has a complete quality system to prevent cutting corners in metal casting procedures.
