Plastic wholesale factory in China: 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.

Advantages of Compression Molding – Compression molding offers several key advantages that make it a preferred manufacturing method for many applications. It’s particularly efficient for large, bulky parts that would be difficult or expensive to produce using injection molding. The process allows for excellent material utilization with minimal waste, especially when using preforms. It produces components with superior surface finishes, dimensional accuracy, and mechanical strength due to uniform pressure and heat distribution. Tooling costs are generally lower than those for injection molds, making it suitable for medium production runs. Additionally, compression molding can process a wide range of thermoset and composite materials, including those with high fiber content that may be unsuitable for other molding techniques. Its ability to produce structurally robust, heat- and chemical-resistant parts contributes to its popularity in industries where performance and reliability are paramount.
We have successfully manufactured more than 8000+ high-quality molds and delivered them to buyers in 20+ countries around the world, and have been in stable operation for many years. As a custom mould manufacturer, We will make a rapid prototype for you, which will help you analyze and review your product design, and help you improve and adjust the product design to conform to the actual manufacturing process. When the product is in the mold, it is relatively soft at high temperature, and the unreasonable ejection method will leave a mark on the surface of the product. This problem is irreversible, but the defect can be compensated by hiding and reducing the cross-section of the ejector pin. Mulan Group Very good at solving such problems.
The main difference between injection molding and blow molding is the types of products that can be produced. Generally, blow molding is the manufacture of hollow containers, such as bottles, pots, barrels and so on. There is no injection port on the surface, Injection molding is used to produce solid parts. The plastic granular material is first melted, and then injected into a closed mold under high pressure for shaping. There will be traces of the injection port on the surface. Usually, compression molding parts select mold steel or aluminum alloy processing to make molds according to the product structure and material. No matter which material is selected, high-quality molds from professional mold manufacturers are very important. Mulan Group, as a highly professional mold manufacturer, Through professional knowledge and advanced manufacturing equipment to provide you with the most precise and efficient mold solutions, and provide the most economically competitive Chinese compression molding manufacturer price quote.

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.

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.
Nylon insert injection molding is a versatile and efficient manufacturing process that involves injecting molten nylon material into a mold cavity to create custom nylon inserts. This technique offers numerous advantages for enhancing the strength, durability, and precision of products. By utilizing a high number of transition words, maintaining an active voice, and incorporating a variety of sentence structures, this article aims to explore the process and benefits of custom nylon insert injection molding.
