Compression manufacturer and supplier right now: Materials Used in Compression Molding – A wide range of materials can be processed using compression molding, including both thermosetting and thermoplastic polymers. Common thermosets like phenolic, epoxy, melamine, and polyester resins are ideal due to their ability to retain shape after curing. These are often reinforced with fibers such as glass, carbon, or Kevlar to enhance mechanical strength and thermal stability. For thermoplastic variants, materials like polyethylene (PE), polypropylene (PP), and polyamide (PA) are used for products requiring toughness and recyclability. Advanced composites combining resin matrices with continuous fiber reinforcement are also molded through this process, enabling lightweight structures with exceptional performance. The choice of material depends on application requirements such as temperature resistance, rigidity, and electrical insulation. With continuous advancements in polymer science, compression molding materials now offer superior flow characteristics and reduced cycle times, making them suitable for demanding industrial applications.

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.
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.
Compression molding parts are suitable for almost all industries. They can not only meet the size standards of complex structures, but also apply to high-temperature components, and meet the corrosion resistance of fuel, chemical, natural gas and other industries, as well as the resistance of equipment operation and mechanical parts. Grinding performance. Mulan Group has focused on the R&D and manufacturing of compression molding parts for more than 10 years, and has continuously accumulated manufacturing experience and expertise. Including: daily necessities such as silicone cleaning brush, tap descaling ball, headwear and so on.
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.
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.
