Plastic factory in China: You can also choose to let us send the mold to you, we will save all the mold numbers and manufacturing information, we can provide a detailed maintenance manual, you only need to operate and maintain as needed. If the parts are damaged or the mold fails, we will also provide technical support and supplement parts to you at any time. Not all mold manufacturers can meet mold manufacturing of all sizes and complex structures, which requires strong manufacturing capabilities and professional knowledge. In the face of different materials and equipment, a lot of successful cases will determine whether the manufacturing of the product goes smoothly. Whether it can deal with unexpected situations that suddenly appear. These are what Mulan Group’s team of mold experts can do for you.
Compression Molding vs. Injection Molding – Compression molding and injection molding are both key plastic-forming methods, but they differ in material behavior, cost, and part design flexibility. Compression molding typically uses thermosetting materials and reinforced composites, while injection molding primarily handles thermoplastics. The former is ideal for producing large, high-strength components, whereas the latter excels in small, precise, high-volume parts. Compression molding generally involves lower tooling costs and simpler mold designs but requires longer cycle times. In contrast, injection molding offers faster production rates but higher setup expenses. Compression molding also accommodates higher fiber content, providing superior mechanical properties and heat resistance. Consequently, manufacturers choose between the two based on performance needs and production scale. Many industries, including automotive and aerospace, use both processes strategically—compression molding for structural parts and injection molding for intricate or lightweight components.

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.
Blow molding is widely used in the production of hollow structure products, such as: water bottles, oil drums, chemical turnover barrels, floats, medical reagent bottles, etc. Injection blow molding is suitable for small container production, and stretch blow molding is suitable for medium and large-volume container products. However, the surface effect of injection blow molded products is better than stretch blow molding, and can be highly transparent and flat. Drinking water bottles are the most typical injection blow molding. Blow molding has many limitations due to the molding principle, so there are a few points that should be paid attention to when designing blow molding products: Only limited to hollow structural parts. The wall thickness is thin and the strength is low. By adding other materials in the multilayer part, the effect of blocking sound and heat sources is increased. (So not recyclable) A second trimming is required to remove burrs and excess material.
Plastic overmolding metal: We use CNC machining/metal casting/sheet metal bending/sheet metal stamping on metal materials to pre-mold the designed substrate, and then wrap the plastic around the metal substrate at one time through overmolding, such as: pipe connectors , Electronic components, etc. Rubber overmolding metal: We use CNC machining/metal casting/sheet metal bending/sheet metal stamping on metal materials to pre-mold the designed substrate, and then wrap the rubber material on the surface of the metal substrate through overmolding to present a soft rubber layer. Such as fitness equipment, medical supplies, hammer handles, children’s toys, etc. Read many more info at https://www.china-plasticparts.com/.
By utilizing advanced computer-aided design (CAD) software combined with state-of-the-art machinery like CNC milling machines or electrical discharge machining (EDM), Mulan precision mold manufacturers can create highly detailed molds capable of replicating intricate geometries down to micron-level tolerances. The precision achieved in these molds guarantees minimal variations during production runs, leading to enhanced product performance and customer satisfaction.
