Foam Cast Mold

Classification of Foam Cast Mold

Classification by Material

Metal molds: Metal molds are usually made of materials such as cast iron and steel. They are characterized by high strength, high hardness, good processability, low cost and long service life. In mass casting production, metal molds are the first choice, especially for scenes with high requirements for mold strength and precision. For example, in the casting of automobile engine parts, metal molds can withstand high temperature and high pressure casting environments to ensure the dimensional accuracy and surface quality of castings.

Plastic molds: The application of plastic molds is on the rise, especially after machinable plastics are introduced to the market and the life of plastic molds is improved, their application is becoming more and more extensive. Plastic molds have the characteristics of light weight, relatively low cost and short production cycle. Suitable for small batch production or cost-sensitive projects. For example, for the casting of the shell of some electronic products, plastic molds can quickly produce samples for testing and improvement.

Ceramic molds: For iron casting, ceramic materials with high thermal tolerance and stability are usually used as foam mold casting materials. Ceramic molds can withstand high temperatures, have good chemical stability, and are suitable for high temperature casting processes. For example, in brass casting, ceramic molds can effectively avoid chemical reactions between mold materials and brass, ensuring the quality of castings.

Classification by function

Single-station mold: Single-station molds have a simple structure and are easy to operate, suitable for the production of small batches and single products. Its advantages are low cost and simple maintenance. For example, for the casting of some small handicrafts, single-station molds can meet production needs.

Multi-station mold: Multi-station molds can perform multiple processes at the same time to improve production efficiency. Suitable for medium-volume production, it can reduce the production cycle. For example, in the casting of some automotive parts, multi-station molds can complete the casting of multiple parts at the same time, improving production efficiency.

Compound mold: Compound molds can complete multiple processes in one stamping process, such as punching, blanking, bending, etc. It has the characteristics of high production efficiency and high precision. It is suitable for casting parts with complex shapes. For example, for the shell casting of some precision electronic products, compound molds can ensure the dimensional accuracy and surface quality of parts.

Fully automated molds: Fully automated molds use automated control systems, which can realize unmanned production, greatly improving production efficiency and product quality stability. Suitable for mass production. In the fields of automobile manufacturing, electronic product manufacturing, etc., fully automated molds are widely used.

Hot runner mold: Hot runner molds keep the plastic in a molten state by heating the runner system, reducing plastic waste and molding cycle. It is suitable for plastic foam casting, especially in the production of large plastic products. For example, in the shell casting of some large household appliances, hot runner molds can improve production efficiency and product quality.

Advantages of different types of foam casting mold

Metal molds

Metal molds have the characteristics of high strength and hardness, which enables them to withstand greater pressure and impact during the casting process, thereby ensuring the dimensional accuracy and surface quality of the casting. For example, in the casting of automobile engine cylinder blocks, metal molds can ensure that the wall thickness of the casting is uniform, the surface is smooth, and the dimensional error is controlled within a very small range. In addition, metal molds have good processability, and molds with complex shapes can be manufactured through various processing methods to meet the needs of different products. Moreover, metal molds are low in cost and have a long service life, which has obvious economic advantages in large-scale casting production.

Plastic molds

Plastic molds are light in weight, easy to carry and operate, and reduce the labor intensity in the production process. At the same time, plastic molds have a short production cycle and can respond quickly to market demand, especially suitable for small-batch production or projects with rapid product updates. For example, in the casting of the shells of some electronic products, plastic molds can produce samples in a short time for testing and improvement, which speeds up the research and development of products. In addition, the cost of plastic molds is relatively low, which is a good choice for cost-sensitive projects.

Ceramic molds

Ceramic molds have high thermal tolerance and stability, can withstand high-temperature casting processes, and are suitable for casting processes with high temperature requirements. For example, in brass casting, ceramic molds can effectively avoid chemical reactions between mold materials and brass, ensuring the quality of castings. At the same time, ceramic molds have good chemical stability and are not easily corroded by casting materials, which prolongs the service life of the mold.

Compound molds

Compound molds can complete multiple processes in one stamping process, such as punching, blanking, bending, etc., and have the characteristics of high production efficiency and high precision. For the casting of parts with complex shapes, compound molds can ensure the dimensional accuracy and surface quality of parts. For example, in the casting of the shells of some precision electronic products, compound molds can complete multiple processes at one time, reducing processing errors and improving product quality.

Fully automated molds

Fully automated molds use automated control systems to achieve unmanned production, greatly improving production efficiency and product quality stability. In mass production, fully automated molds can reduce errors caused by manual operation, improve production efficiency and product quality. For example, in the fields of automobile manufacturing, electronic product manufacturing, etc., fully automated molds are widely used, reducing production costs for enterprises and improving market competitiveness.

Hot runner molds

Hot runner molds keep plastics in a molten state by heating the runner system, reducing plastic waste and molding cycles. In plastic foam casting, hot runner molds are particularly suitable for the production of large plastic products, which has the advantages of improving production efficiency and product quality. For example, in the casting of the shells of some large household appliances, hot runner molds can ensure the fluidity of plastics in the runner, reduce product defects, and improve product quality.
