LSR Mold

LSR mold is specially designed moulds used in the production of silicone injection molding. And Liquid Silicone Rubber (LSR) is a highly versatile material for its excellent durability, flexibility, and heat resistance.

LSR molding is commonly used to produce parts that require precision, strength, and high-quality performance. These molds are essential in the production of components that are used across a wide range of industries, such as medical, automotive, and consumer.

By LSR injection molding process, our mold manufacturers can create great designs with consistent quality and rapid production speeds. The mold design allows for high precision and the ability to form complex shapes without compromising the material's integrity.

LSR mold finds applications in various industries.

• Medical Industry: For producing medical devices like o ring seals, gaskets, and valves.
• Automotive Industry: For creating high-temperature-resistant components such as seals and connectors.
• Consumer: For parts like Bathroom, Kitchenware, smartphone seals, connectors, and protective covers.
• Baby Products: We can make safe, non-toxic items such as baby bottles, teething toys, and pacifiers.
• Labor Protection: LSR Injection molding produce anti toxic air pollution mask, mask valves.

LSR injection molding- two main types of injection molding machines: horizontal injection machines and vertical injection machines.

Horizontal Injection Machines

In horizontal injection molding, the machine utilizes a direct pressure clamping system. It offers high rigidity and precise LSR (Liquid Silicone Rubber) component production utilizing high-pressure direct injection, hydraulic clamping, and ejection force.

Vertical Injection Machines

Vertical injection molding machines are typically used for smaller parts and components that require multiple mold cavities or overmolding.

The fully automatic vertical injection moulding machine has 2 slide plates which can install 2 lower molds and 1 upper mold. It can cooperate with the double station operation to improve the production efficiency. And can be combined with the robot arm to achieve automated production.

Liquid silicone injection moulding process: the use of high-temperature curing liquid silicone silicone A/B two-component material, liquid silicone injection moulding machine supporting liquid silicone injection mould for production, the entire production process can achieve fully automated production, very effective in saving labour and production costs.

The quality of silicone products produced by this process is the best, the overall appearance of the moulding line does not require subsequent manual processing, saving time.

1. Precision and Complexity

One of the big advantages of liquid silicone rubber is its ability to create highly precise and complex shapes. So the injection molding process allows for complicated designs and fine details.

2. Minimal Waste

The efficiency of lsr injection molding combined with the very low error rate of liquid silicone rubber results in minimal material waste during production. Not only lowers costs but also supports sustainability initiatives by reducing environmental impact.

3. Excellent Material Properties

Liquid silicone rubber has a lot benefits, including high tight level, temperature resistance, and durability. The precise control over the filler content and distribution within the silicone matrix is crucial for achieving the desired strength without compromising the material's elasticity. These characteristics make it suitable for a wide range of applications, from medical devices to auto parts.
