Insert Plastic Injection Molding (IM) is a specialized process offered by KST. It involves embedding metal, plastic, or ceramic parts within plastic to enhance the structure of a product.
During IM, the desired part is carefully positioned within a mold cavity. The chosen plastic material is then injected directly around the part, resulting in a unified component with the insert(s) securely embedded in the plastic. Engineered plastics are typically used in this process to improve durability, tensile strength, and achieve weight reduction.
IM presents an efficient and straightforward alternative to assembling individual parts using soldering, connectors, fasteners, or adhesives. By leveraging the capabilities of plastic, it also enables cost reduction by minimizing the amount of expensive metal required to manufacture a part. A key advantage of this process is that it can be performed using a standard single-shot injection machine, leading to lower tooling costs compared to multi-shot processes.

The process of Injection Molding (IM) offers the advantage of securely bonding multiple components together using thermoplastic materials. When combined with automation, this process significantly reduces assembly and labor costs. An excellent example of this is the utilization of a stamped metal insert to create a perforated IM part, effectively generating an insulated multi-path circuit.
IM provides the opportunity to eliminate the need for fasteners and connectors. By harnessing the bonding strength of resin and metal inserts, IM enables the production of smaller, lighter, and more durable components.
Engineers highly appreciate the flexibility and possibilities afforded by IM. It allows for the integration of complex stamped metal or formed parts. The external resin layer provides insulation, while the internal metal component creates a dedicated multi-path electric circuit.
IM components greatly reduce the likelihood of parts loosening, misalignment, or electrical disconnection. Moreover, the use of thermoplastic resin enhances the shock and vibration durability of the materials.
IM involves the insertion of various metals, including frame die castings, plated copper pins, sockets, and wire embedded into engineering plastic or thermoplastic rubber (TPR).
TPR + Metal Frame (3C Mechanical Parts)
ABS + Aluminum Die Casting (Sports/ Medical Parts)
Engineering Plastic + Plated Pin + Wire (Electrical Connectors)
Engineering Plastic + Copper Pin/Contact (Precision Electronic Components)
Liquid Injection Molding (LIM) is a highly preferred manufacturing process for creating solid silicone rubber products, thanks to the outstanding durability and flexibility characteristics of liquid silicone rubber (LSR) or similar elastomeric materials. LIM enables the production of a wide range of products, including:
The versatility of LIM allows for the precise molding of complex shapes and intricate designs, ensuring the desired functionality and performance of the end products. With its exceptional material properties, LIM delivers superior quality and reliability across various industries.
Liquid injection molding utilizes the exceptional characteristics of Liquid Silicone Rubber (LSR), necessitating a streamlined and consistent mechanical mixing process instead of a labor-intensive one. This closed-loop process employs a pump and mixing unit to thoroughly blend and dispense the liquid material into a molding press. Following the curing stage, the press opens, and the product is either manually or robotically extracted.
Liquid injection molding stands out as one of the most versatile and cost-effective manufacturing methods available today. It finds application in a multitude of industries and markets, including:
We source our LSR materials from trusted manufacturers such as Shin Etsu, Dow Corning, and GE Silicones. These reputable suppliers ensure the highest quality and performance of our liquid injection molded products.
When implemented with precision, Liquid Injection Molding (LIM) consistently delivers high-quality molded components in large quantities. However, it is crucial to assess its suitability for each specific application. One key consideration is determining whether silicone is the optimal material choice. While silicone offers numerous advantages, it may not be ideal in certain circumstances.
It is essential to evaluate the environmental and chemical conditions the molded components will encounter. For instance, silicone can react unfavorably with pressurized steam at temperatures exceeding 150°C. This reaction can lead to the breakdown of the material’s siloxane polymer and the degradation of its essential properties.
To ensure the longevity and optimal performance of the molded components, it is important to explore alternative materials that can withstand the specific environmental and chemical conditions they will be exposed to. Conducting a comprehensive material analysis and consulting with experts can help identify the most suitable material for the intended application, guaranteeing the desired functionality and longevity of the molded components.
Liquid Injection Molding (LIM) offers several features and benefits that make it a preferred manufacturing method for various applications. Here are some key features and benefits of LIM.
Overall, the features and benefits of LIM make it a versatile and effective manufacturing process, particularly for applications that require precision, durability, complex designs, and high-volume production.
