Multi-shot or multi-component injection molding is a aggregative term that refers to an injection molding process where two or more materials are molded in the same molding machine and process. It turns out that an integrated molded component consisting of various materials and substrates.
In 2K LSR molding, the LSR and thermoplastic parts are both molded and combined in the same molding cycle. The molds for the LSR and thermoplastic parts use the same platen in the molding machine. Normally the mold for the LSR parts is on the top and the thermoplastics mold is on the bottom.
During 2k LSR injection molding, there are two kinds of molds used: transfer molds and rotary molds. Using a transfer molding process, after the thermoplastic parts are molded, the molded parts are automatically removed from the mold and transferred up to the LSR mold for accomplishment.
Selecting a multi-shot process instead of a single-material part and then assembling, heat-staking, ultrasonic welding, or using any other secondary process to mechanically combine two or more substrates has a number of advantages.
2K LSR Molding is essential for any application that requires sealed connectors. Creating similar housings without 2K LSR Molding necessitates additional tooling and assembly processes, increasing costs while increasing the possibility of assembly error.
Furthermore, the 2K process can broaden design options and lead to improved product design opportunities. LSR material is more resistant to weather, chemicals, and flame than traditional sealing materials used in other applications. When combined with a wide usable temperature range (-90 to +200 C°), using 2K LSR can be a key manufacturing strategy for distinguishing a superior sealed product from the competition.

With our design and process engineering abilities, CN Mould & Plastic Limited has carved out a niche in 2K LSR Molding. That expertise is demonstrated by successful programs that employ 2K LSR Molding, as well as a long history of designing sealed solutions for a wide range of applications. Externally, CN Mould & Plastic Limited collaborates with best-in-class vendors for materials, processing, and tooling to ensure a high-quality result where it matters most--the seal. 2K LSR molded products with that seal can achieve an IP69K rating and pass the j2030 power-wash test. These products also save money by removing assembly steps, lowering tooling and molding costs, and lowering material usage and component counts.
