Quality blow molding wholesale manufacturer and supplier: 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.

Types of Blow Molding Processes – Blow molding encompasses three main types: extrusion blow molding (EBM), injection blow molding (IBM), and injection stretch blow molding (ISBM). In extrusion blow molding , molten plastic is extruded into a parison and then inflated inside a mold — ideal for making bottles, containers, and large industrial parts. Injection blow molding combines injection and blow molding by forming a preform first, then blowing it into shape; this yields precise, uniform parts commonly used in pharmaceuticals and cosmetics. Injection stretch blow molding adds a stretching step before blowing, improving strength and clarity — perfect for producing PET beverage bottles. Each method offers distinct advantages depending on production volume, material, and desired product characteristics. Choosing the right blow molding process involves balancing cost, speed, and performance requirements, making process selection a crucial part of manufacturing design.
If your product quantity is relatively small, we can provide fast mold service, which is a fast turnaround and low price mode, but the disadvantage is that the quality of the mold is not good, and it is unable to undertake too many product manufacturing tasks. From the design of the mold to the final test of the mold, all the processes are carried out in our internal injection workshop and the mold workshop. We reserve a lot of material warehouses for manufacturing high-quality molds, which are in line with most plastic products, there are many spare parts in reserve, we can call for use at any time. The injection molding workshop is next to the mold workshop. After the mold is manufactured, the injection molding equipment can be installed and tested within a few hours. This is the key to rapid response.
Blow molding is a plastic molding process for rapid production of hollow structure products. Many products in life will choose injection blow molding for packaging, such as water bottles, oil drums, children’s toys, etc. This is an economical and efficient plastic molding process. It is also suitable for mass production of plastic products. Mulan Group has been engaged in the production of blow molding parts for more than 15 years. It has two large blow molding manufacturing bases that produce small injection blow molding parts, such as medical test tubes, cosmetic bottles, drinking water bottles, etc. And large-scale extrusion blow molding products, such as insulation barrels, oil drums, car water tanks, tool boxes, etc.
Common rotomolding products include: water storage tanks, oil storage tanks, large buckets, kayaks, fitness equipment, trash cans, mobile toilets, traffic barriers, cartoon dolls, septic tanks, etc. Mulan Group has been focusing on helping customers develop, design and manufacture a series of customized rotational molding services, with rich experience and expertise. In 2014, we established a large rotomolding factory and established an advanced manufacturing system with 6 large-scale rotational molding parts. The automated rotational molding equipment has a maximum rotation capacity of more than 10 feet. We actively respond to all complex rotational molding projects at any time, constantly challenge opportunities and raise technical barriers.
Generally, overmolding is an injection molding technology that effectively reduces costs and is widely used, and requires rich manufacturing experience and high mold manufacturing standards. It can quickly reduce the cost of secondary assembly of traditional plastic parts, as well as applications that do not require harmful glue, and can achieve stable quality, high efficiency, and reduce the risk of defective products during mass production.

Place the thermoset plastic material in the compression molds cavity, melt the thermoset material by heating, close the mold with pressure, and the melted thermoset material will instantly fill the entire cavity under the action of pressure. In this process, it is very important to control the weight, shape, and specifications of solid materials, which will directly affect product quality. Thermosetting materials will reach the best curing state under the control of stable high pressure and high temperature. Compression molding parts are ejected, and the remaining materials are cleaned manually or by using cutting molds.
A precision mold, often referred to as a high-precision or close-tolerance mold, represents an invaluable tool in the manufacturing industry. It is meticulously designed and constructed to produce complex and intricate components with utmost accuracy and consistency. A precision mold serves as a blueprint that defines the shape, size, texture, and functionality of various products across different sectors. Crafted with engineering expertise and cutting-edge technology, this sophisticated tool allows for efficient mass production while ensuring exceptional quality standards.
