Best compression mold manufacturer and supplier: 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.

Challenges and Limitations of Compression Molding – Despite its advantages, compression molding presents several challenges that manufacturers must manage carefully. One limitation is relatively long cycle times compared to injection molding, which can impact productivity for high-volume production. The process also requires precise control of temperature, pressure, and curing time to prevent defects like voids, incomplete filling, or warping. Material handling can be labor-intensive, especially for manually loaded preforms. Tool design and maintenance are critical since uneven heating or wear can affect product consistency. Additionally, part design flexibility is somewhat limited; intricate geometries with deep undercuts are difficult to achieve. While automation can mitigate some of these issues, it increases upfront costs. Nonetheless, ongoing improvements in press technology, mold design, and material formulations continue to address these challenges, expanding the potential of compression molding in modern manufacturing.

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.
Blow molding is a process in which a hollow product formed by the expansion of a hot-melt plastic tube closed in a mold by means of gas pressure. The blow molding process was used to produce LDPE vials in World War II. In the 1950s, with the birth of HDPE materials and the development of blow molding machines, the blow molding process was widely used and the technology was upgraded. According to the different plastic blank tubes, it can be divided into extrusion blow molding, injection blow molding, stretch blow molding and multi-layer blow molding. Compression molding process A manufacturing process for molding polymers such as thermosetting plastics, thermoplastics, elastomers, rubber and plastic materials, and natural rubber. For example: children’s pacifiers, sealing rubber rings, power insulation parts, electrical enclosures, etc.
Rotational molding has also become rotomoulding. It is a kind of manufacturing process that is very versatile and suitable for various industries. It can be customized to produce hollow plastic molding products of various shapes and sizes. No matter the batch is large or small, the volume is large or small, roto molding services Both can achieve multi-functional manufacturing functions. Professional rotomolding mold engineers will have great design freedom, because this is a plastic molding process that does not limit any shape and size, similar to casting technology.
Sheet metal prototype is a method to quickly create design details of metal parts through manufacturing processes such as cutting, bending, stamping, and stretching of metal plates. In this process, it will try to use as little mold investment as possible. It is widely used in the development and research phase of metal products to help customers test product functionality and design rationality. More often, we rely on sheet metal prototype to provide metal inserts for the plastic molding process of in-mold molding, and the prototype can be produced within a few hours.

Mainly used as structural parts, connectors, protective parts and electrical insulation parts. It is widely used in industry, agriculture, transportation, electrical, chemical, construction, machinery and other fields. Because of the reliable quality of molded products, they have also been used in weapons, aircraft, missiles, and satellites. The molding cycle in the entire production process is long, the efficiency is low, and the staff has a large physical consumption. It is not suitable for molding complex products with depressions, side slopes or small holes.
