What is Compression Mold?
Compression molding is a manufacturing process used to produce composite components in high volumes. This method utilizes thermoset plastic materials, which may be in free-flowing granular form or viscous state. Through this process, various parts with diverse lengths and thicknesses can be produced. Compression molding is commonly used to manufacture gaskets and seals made from synthetic rubber, silicone, and natural rubber. These high-quality, stiff, and durable rubber components serve multiple industries, including automotive.
During compression molding, raw rubber material is placed inside a pressurized mold cavity. A plug secures the top of the mold, sealing it while connecting to equipment that provides both heating and pressurization. The mold is then heated and pressurized, causing the rubber to liquefy and expand. After expansion, the material is allowed to cool under pressure, taking the shape of the mold cavity. Once the rubber solidifies, the finished component can be ejected from the mold. Compression molding enables the production of rubber products in various shapes and configurations.
What are the different types of compression molds?
Various compression mold types are available in the market, often named according to the compression molding material used—such as SMC molds, BMC molds, GMT molds, or LFT molds. However, they are most commonly classified based on their structural configuration.
Compression Mold Advantages
- Compression molds are generally simpler in design compared to their injection mold counterparts, as they do not require sprue and runner systems.
- Superior quality and consistency, high precision, uniform wall thickness, and excellent surface finish can be achieved through well-engineered mold design.
- Reduced production time, increased productivity, and greater efficiency result from the elimination of waiting periods between cycles.
- Lower tooling costs are achievable, and the use of high-quality steel extends mold life for long-term value.
What kind of mold steel is used for compression molds?
The steels used for compression molds include alloy steel and carbon steel. Alloy steel is a high-alloy steel with very low carbon content, making it extremely tough. Carbon steel contains more carbon than alloy steel, resulting in lower hardness but also lower cost compared to alloy steel. Alloy steel is the most commonly used material for compression molds, as it must withstand the pressure of molten material and low-alloy steels can tolerate higher temperatures than carbon steels.
We also employ optimal heat treatment processes and advanced milling capabilities to meet the precision requirements of high-quality compression molds. Fuming controls flash within ideal ranges through CNC processing technology and specialized mold steel techniques, minimizing material waste wherever possible.
