    Features of LSR and LIM

    LSR, (Liquid Silicone Rubber)

    Refers to a two-component liquid silicone material that can be injected into a mold and then cured to form a solid elastomer. It offers several advantages:

    1. High Precision: LSR molding allows for the production of intricate and precise parts with tight tolerances, ensuring consistent quality and dimensional accuracy.
    2. Heat Resistance: LSR exhibits excellent thermal stability and can withstand extreme temperatures, ranging from -50°C to 250°C, without compromising its mechanical properties.
    3. Chemical Stability: LSR products possess exceptional resistance to chemicals, UV radiation, and moisture, making them suitable for demanding applications in various industries.
    4. Biocompatibility: LSR is biocompatible and hypoallergenic, making it ideal for medical and healthcare applications such as medical devices, implants, and baby products.

    LIM, (Liquid Injection Molding) 

    Manufacturing process that utilizes a precision-machined mold to inject liquid silicone rubber into the mold cavity. It offers several advantages:

    1. Design Freedom: LIM enables the production of complex geometries and intricate details, including undercuts and thin walls, allowing for innovative and unique product designs.

    2. Overmolding Capabilities: LIM facilitates the overmolding process, enabling the encapsulation of different materials or components, such as metal inserts or electronics, within the silicone rubber part.

    3. Reduced Cycle Time: LIM provides fast curing times, enabling shorter cycle times and increased production efficiency.

    4. Consistency and Reproducibility: LIM ensures consistent part quality and repeatability, resulting in uniform products throughout the production run.

    By leveraging the advantages of LSR and LIM, our company specializes in delivering high-quality silicone rubber products that meet the unique needs of various industries.

    LSR (Liquid Silicone Rubber) Applications

    Medical and Healthcare

    Widely employed in medical devices, implants, and equipment due to its biocompatibility, hypoallergenic nature, and resistance to high temperatures and sterilization methods. Examples include silicone catheters, respiratory masks, surgical instruments, and prosthetics.

    Automotive

    Utilized in automotive components that require durability, flexibility, and resistance to extreme temperatures. It is used for gaskets, seals, connectors, and electrical insulation. LSR's excellent sealing properties make it suitable for applications such as engine gaskets and automotive lighting.

    Electronics

    Used in the electronics industry for its electrical insulation properties, resistance to heat, and moisture protection. It is employed in keypads, connectors, cables, and seals for electronic devices. LSR also provides reliable protection against dust, water, and vibration.

    Baby Products

    Commonly found in baby care products due to its safety, softness, and hygienic properties. It is used for pacifiers, bottle nipples, teething toys, and baby feeding products.

    Industrial Applications

    Heat resistance, chemical stability, and flexibility make it suitable for industrial applications. It is used in seals, gaskets, O-rings, and other components that require reliable performance in harsh environments.

    Food and Beverage

    Utilized in food-grade applications where hygiene and safety are crucial. It is employed for producing food molds, baking molds, and kitchen utensils. LSR's resistance to high temperatures and excellent release properties make it ideal for food processing and baking.

    LSR’s versatility and unique properties make it a preferred choice in various industries that require high-quality silicone products. Contact us for more information or if you have specific product requirements.

    Options for LSR customized products

    Product Design

    Custom shapes, sizes, contours,logos, and branding elements.

    Color and Appearance

    Various color options, including translucent and opaque finishes.

    Packaging and Labeling

    Customized packaging and labeling solutions. meet specific or regulatory requirements.

    Material Properties

    LSR formulations can be tailored to meet specific requirements, such as hardness, flexibility, and resistance to chemicals, UV radiation, or extreme temperatures.

    Surface Treatments

    Custom surface treatments like coatings, textures, or finishes can be applied to enhance the aesthetics, grip, or functionality of the LSR product.

    Overmolding

    LSR allows for overmolding, which involves encapsulating other materials or components within the silicone part. This enables the integration of multiple materials or functional features into a single product.

    Process flow of LSR

    图片
    1. Mixing: LSR is made by combining two components, a silicone base(A) and a cross-linking agent(B). These are carefully measured and mixed together.

    2. Injection Molding: The mixed LSR is injected into a specially designed mold, which gives the product its shape. The mold is made with precision to create the desired final product.

    3. Curing: Once injected into the mold, the LSR is cured or solidified. This is done by applying heat or using a combination of heat and a catalyst. It ensures that the LSR becomes a solid material.

    4. Mold Opening and Ejection: After curing, the mold is opened, and the solid LSR product is removed from the mold. The mold is designed to make this process easy and efficient.

    5. Finishing Touches: The LSR product may undergo additional steps like trimming excess material or adding surface treatments to achieve the desired appearance and functionality.

    Steps of customize Liquid Injection(LIM) Mold and Production

    Requirement Gathering

    Gathering detailed information from the customer about their specific product requirements, including design specifications, dimensions, functionality, and any special features or considerations

    Requirement Gathering

    Design and Engineering

    We will work closely with the customer to develop a mold design that meets their requirements. This includes creating 3D CAD models, performing feasibility studies, and considering factors like mold complexity, parting lines, gating, and ejection methods.

    Design and Engineering

    Prototype Development

    We will create prototypes of the mold or the actual product using rapid prototyping techniques, such as 3D printing . Prototypes allow the customer to evaluate the design, make any necessary adjustments, and ensure it meets their expectations before proceeding with mass production.

    Prototype Development

    Mold Fabrication

    Once the design is finalized, we will proceed with the fabrication of the custom mold. This involves using precision machining techniques, such as CNC milling or EDM (Electrical Discharge Machining), to create the mold cavity and other necessary features.

    Mold Fabrication

    Mold Testing and Validation

    We will perform tests on the mold to ensure it functions correctly and produces high-quality parts. This may involve conducting trial runs, adjusting process parameters, and fine-tuning the mold design if needed.
