Cast molding refers to the processing process in which liquid raw materials are poured into a mold and cooled and solidified at room temperature. Zhongde has many years of casting experience. Our experienced engineers can accurately analyze whether the product is suitable for casting products according to the product structure.

For example, Zhongde will offer and recommend reusable metal casting molds for customers who need mass production of making identical products. The reusable metal casting molds are useful since they can be used repeatedly. Zhongde provides casting for different metal casting molds with 3D printing such as silicone casting molds, steel casting molds, aluminum casting molds, and brass casting molds. Zhongde also focuses on different plastic mould casting like TPE casting, PU urethane casting, and polymer cast molding.

Difference between Molding and Casting

Casting typically uses the material of metal which is melted in the die to create the final form, while molding uses the material of plastics which is melt in a mold to generate the final form. Generally, molding is faster than casting in the process so it's better to choose to mould when you need to produce a large number of products. Molding is also suitable for various materials. However, if you pursue the accuracy of the products of high-quality, casting is a better choice.

FAQs of Cast Molding

What is the difference between cast nylon and extruded nylon?

Cast nylon tends to be slightly more ductile than extruded 6/6 nylon, it can procduced in much larger shapes and tends to be more cost-effective in larger cross-section shapes.

What is the difference between molding and casting?

Molding or Mold making is the act of creating the cavity that carries a negative or reverse impression of an original model. Casting is the act of pouring liquid material into the cavity of a mold.

Does casting resin shrink?

All resins shrink when they change from liquid to solid and all generate heat as they polymerize, and this causes problems. Because heat accelerates chemical reactions, all resins cure from the inside out.
