Thermoformer parts factory by Mulan Group: History and Development of Compression Molding – The origins of compression molding trace back to the early 20th century, coinciding with the development of thermosetting plastics like Bakelite. Initially, it provided a practical way to mass-produce plastic components for electrical insulators, handles, and decorative items. Over time, as synthetic polymers advanced, compression molding adapted to accommodate reinforced composites, such as glass- and carbon-fiber materials. These innovations expanded its applications to aerospace and automotive industries, where lightweight yet strong parts are crucial. By the 1950s, the process became a cornerstone for manufacturing fiber-reinforced plastics, particularly for high-performance structural components. Modern developments, including computer-controlled presses and precision mold design, have significantly enhanced consistency and efficiency. Today, compression molding remains one of the most reliable methods for producing composite and thermoset parts, balancing tradition with innovation to meet contemporary industrial demands.

You can also choose to let us send the mold to you, we will save all the mold numbers and manufacturing information, we can provide a detailed maintenance manual, you only need to operate and maintain as needed. If the parts are damaged or the mold fails, we will also provide technical support and supplement parts to you at any time. Not all mold manufacturers can meet mold manufacturing of all sizes and complex structures, which requires strong manufacturing capabilities and professional knowledge. In the face of different materials and equipment, a lot of successful cases will determine whether the manufacturing of the product goes smoothly. Whether it can deal with unexpected situations that suddenly appear. These are what Mulan Group’s team of mold experts can do for you.

Extrusion Blow Molding Explained – Extrusion blow molding (EBM) is one of the most widely used forms of blow molding. It begins by extruding a molten tube of plastic, called a parison, between two halves of a mold. The mold then closes around the parison, and compressed air inflates it until it conforms to the mold cavity. After cooling, the mold opens and ejects the finished part. EBM is especially suited for making hollow products like bottles, jerry cans, and drums. One major advantage of this method is its flexibility in producing items of various shapes and sizes, from small containers to large tanks. Multi-layer EBM can even combine different plastics to achieve barrier properties, such as resistance to oxygen or UV light. Despite its simplicity, process control — including parison temperature and thickness distribution — is critical for ensuring consistent product quality and minimizing material waste.
