PP Injection Molding has become one of the mainstream molding technologies in the field of plastic injection molding due to its unique material advantages and process flexibility, and occupies an important position in industrial manufacturing. Polypropylene has become one of the outstanding plastic injection molding technologies because it can adapt to multiple scenarios, has cost advantages and durability. It is polymerized from propylene monomers and naturally has the "genes" of high impact resistance, chemical corrosion resistance and low moisture absorption. The core means of converting it into an actual product is the classic injection molding process: injecting molten PP into a precision mold, and after cooling and solidification, a product of a predetermined shape can be obtained.

Overmolding refers to the fastest, multi-step process of molding a layer of polymer over a substrate part using TPU injection molding methods. It usually represents the mechanical entanglement of polymer molecules. Usually, it is an injection molding process. The substrate part (the toughest part) is usually made of plastic and made by the plastic overmolding process. From toothbrush manufacturing to vibration reduction, and critical internal durable and elastic parts in automobiles and aerospace, the overmolding of small-size parts has received great attention. The process is carried out by chemical or physical interlocking.

IMD injection molding is a production method that uses injection molding to combine decorative film with injection molding. To produce a high-quality appearance effect and endow the product great wear resistance, scratch resistance, chemical corrosion resistantism, and other properties, this technology embeds the decorative film into the plastic product's surface during IMD molding. Originally developed in the United States in the 1980s, the IMD injection molding was first applied in the production of automotive interior components. It was afterwards rapidly broadened into many areas including medicine, communications, electronics, and home products.

By injecting molten material into a mold, PC injection molding—a widely used manufacturing method—enables mass production of items with sophisticated forms and designs. PC means Polycarbonate, is a strong thermoplastic with several physical characteristics appropriate for uses where toughness, transparency, and high temperature resistance are crucial. One of the most adaptable materials for plastic injection molding, its unusual design permits great coloring, surface treatment, and shape customizing. Using it requires careful consideration of certain process parameters to guarantee the quality and longevity of the ultimate product.

Insert injection molding represents a cutting-edge manufacturing paradigm that combines molten thermoplastics with pre-positioned metallic or non-metallic inserts within specialized insert injection molds. This technology fundamentally differentiates itself from conventional injection molding through its requirement for automated or manual insert loading into molds prior to resin injection. By enabling the fusion of dissimilar materials—ranging from engineering plastics to titanium alloys—insert injection molding produces multifunctional composite components with enhanced mechanical strength, thermal stability, and design complexity.

Silicone rubber injection molding is an advanced manufacturing process that is widely used in many industries to efficiently produce complex silicone parts. This process involves injecting heated silicone material into a mold, cooling and curing it to form the desired shape. In this article, KRMOLD will take a deep dive into the steps and advantages of using silicone rubber injection molds to help you better understand this manufacturing technology.
