Plastic manufacturer right now: Plastic injection molds are made of mold steel, aluminum alloy and other materials. It is divided into a fixed end and a sliding end. Generally, the sliding end has a feed injection hole, a support plate, an ejector box, an ejector rod, an ejector pin, an ejector plate and other accessories. Mold manufacturing and design is a professional and challenging job, which can directly represent whether a manufacturer has the technical ability to provide a series of solutions for high-precision products.

The Compression Molding Process Step-by-Step – The compression molding process begins with preparing a measured charge of raw material—often in the form of pellets, powder, or preform. This material is preheated to enhance flow before being placed into the lower half of a heated mold cavity. The mold is then closed, and pressure is applied using a hydraulic press. Heat and pressure cause the material to soften and conform to the mold’s contours, filling every cavity and eliminating voids. For thermosetting materials, the heat initiates a chemical crosslinking reaction, permanently hardening the part. Once curing is complete, the mold is opened, and the finished part is ejected. The process may include post-curing or trimming to achieve final specifications. This straightforward yet precise sequence ensures high-quality molded components, with cycle times ranging from a few minutes to over an hour, depending on material type and part complexity.

The History and Evolution of Blow Molding – The origins of blow molding can be traced back to ancient glass-blowing techniques. However, its industrial application began in the 1930s with the introduction of thermoplastic materials. The first blow-molded plastic bottles were produced in the late 1930s using cellulose acetate, but the technology gained widespread use after World War II, when polyethylene became commercially available. In the 1950s, the first automatic blow molding machines revolutionized mass production, making it possible to produce thousands of bottles per hour. Over the decades, advances in machinery, materials, and computer control have refined the process. Modern systems now feature precision temperature control, automation, and real-time monitoring for consistent quality. The evolution of blow molding reflects broader manufacturing trends — from manual craftsmanship to fully automated, high-speed systems — enabling industries to meet the growing demand for affordable and sustainable packaging solutions worldwide.

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.
