Excellent plastic molding wholesale manufacturer and supplier: As an injection mold manufacturer, Mulan Group has been engaged in plastic molding molds for more than 25 years. We have a professional in-house mold manufacturing factory, located in Shanghai, China, a high-quality mold manufacturing base, equipped with a team of engineers with rich manufacturing experience and professional knowledge. Rely on digital programming software and equipment to customize precision injection mold services after the part design is completed. Allow the material to fill the mold cavity without obstacles to ensure that the product will not have defects. For some appearance parts, a smooth surface is an important factor in obtaining market value. We will use very small pinhole feeds. There are no traces on the surface of the product, and it is hidden on the surface of the product installation part.

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.

Injection Stretch Blow Molding in the Beverage Industry – Injection stretch blow molding (ISBM) is the process of choice for making PET bottles, particularly in the beverage industry. The method begins by injection molding a preform, which is then reheated, stretched longitudinally, and blown into its final shape within a mold. The stretching aligns the polymer chains, greatly enhancing the material’s strength, clarity, and gas barrier properties. This makes ISBM bottles ideal for carbonated drinks, juices, and water. The process is divided into single-stage (integrated) and two-stage (separate preform and blow processes) systems, offering flexibility depending on production needs. ISBM’s ability to create lightweight yet durable bottles has driven its dominance in global packaging. Ongoing innovations, such as energy-efficient reheating systems and recyclable PET variants, are helping manufacturers reduce costs and environmental impact while maintaining the quality and performance consumers expect.

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.

We have 6 large-scale automated CNC rotational molding equipment, 7*24 hours for production tasks, to ensure that all products can be delivered to customers on time, and our production plan is not limited by the number, at least one piece can start our production plan. In order to better customize the rotomolding parts according to the customer’s design, we will perform secondary processing on the finished product to ensure the realization of the functional application of the product. like: In-mold inlay: Fix metal fasteners or other metal parts in the mold, used for fastener assembly between products, metal reinforcement ribs and other functions.
