What are the factors that affect liquid silicone molding?

Liquid silicone integrated molding can achieve environmental protection and sustainable development.

There are many influencing factors for liquid silicone integrated molding, from raw material quality, molding temperature, mold structure to environmental temperature, each link may have a profound impact on the final molding effect.

First of all, the composition and properties of silica gel will directly affect the effect of integrated molding. The viscosity, fluidity, curing speed, hardness and other characteristics of silica gel will affect the molding process. High-quality silica gel raw materials usually have good fluidity and toughness, which can ensure that the silicone can be successfully filled in the mold during the molding process, while maintaining good physical properties after the molding. The poor quality of silica gel raw materials may lead to bad phenomena such as fractures and bubbles in the molding process, affecting the molding quality.

Secondly, the molding temperature, humidity and other environmental conditions will also affect the liquid silicone integrated molding. Especially in the curing stage, the control of environmental conditions is crucial to the quality of the molded product. Under normal circumstances, the viscosity of silica gel will decrease with the increase of temperature, and the fluidity will increase. Therefore, it is necessary to reasonably control the molding temperature during the molding process to ensure that the silicone can fully fill the mold and avoid gaps or bubbles. At the same time, too high molding temperature may also lead to silicone aging or burning, affecting the quality of the finished product.

Liquid silicone integrated molding can achieve environmental protection and sustainable development.

In addition, the design and manufacturing quality of the mold is crucial to the liquid silicone integrated molding. The surface finish of the mold, dimensional accuracy, exhaust system design, etc., will affect the quality of the molded product. The design of the mold should take into account the fluidity and molding characteristics of the silicone to ensure that the silicone can be successfully filled to each fine part. Molds with more complex structures may require higher molding temperatures to ensure that the silicone can be filled to every corner. At the same time, the material and surface roughness of the mold will also have an impact on the molding quality.

Finally, the ambient temperature is also a factor that can not be ignored affecting the integrated molding of liquid silicone. In the winter or low temperature environment, the fluidity of silica gel may be reduced, resulting in molding difficulties or adverse phenomena. Therefore, in the production process, the molding temperature and process parameters need to be reasonably adjusted according to the change of environmental temperature to ensure stable molding quality. In addition to the above factors, liquid silicone integrated molding may also be affected by other factors, such as molding pressure, vulcanization time, etc. These factors need to be adjusted and optimized according to the specific production conditions and product requirements to ensure the best quality and performance of the final product.

To sum up, there are many influencing factors of liquid silica gel molding, and it is necessary to comprehensively consider raw material quality, molding temperature, mold structure, environmental temperature and other factors in the production process, and ensure that the final molding effect reaches the best state through reasonable process parameter adjustment and control.

In addition, the adhesion of silicone is also the key, you can choose silicone products with high adhesion. The quality of silicone directly affects the effect of the coating, therefore, it is important to choose silicone materials with good elasticity and aging resistance. 2, the surface of the hardware is treated. Before the adhesive coating, the surface of the hardware should be cleaned to remove impurities such as oil and dust to improve the adhesive force. At the same time, a base coating can be applied to further enhance the adhesion between the silica gel and the hardware.

1. First of all, we must ensure that the selected silica gel material has good compatibility with the substrate and can maintain stable performance under different temperature, humidity and chemical environments. In addition, the adhesion of silicone is also the key, you can choose silicone products with high adhesion. Therefore, the vulcanization time should be set reasonably according to the type and thickness of silica gel to ensure that the silica gel is fully vulcanized. 2, control the molding temperature.

Silicone products，Silicone product processing

The rationality of liquid silicone mold flow channel design:

The flow path should be designed to ensure that the liquid silicone can fill the mold cavity evenly and quickly. The size and shape of the flow path are critical to the injection molding process of the LSR mold. The size of the flow path should ensure that the LSR material flows evenly during injection and does not generate excessive shear heat. The shape of the flow channel should avoid sharp turns and mutations as much as possible to reduce the resistance and pressure loss of the fluid.

When designing the flow path, it is necessary to ensure that the liquid silicone can fill all parts of the mold at the same time to avoid uneven filling caused by the sequence. In order to achieve the balance of the flow channel, diverting channels and multiple gates can be used to make the liquid silica gel evenly distributed in the mold cavity. The length and proportion of the runner should be determined according to the specific mold design and the flow characteristics of the LSR material. Too long a flow path will increase the injection pressure and time, while too short a flow path may cause uneven flow or bubble formation.

The number and distribution of liquid silicone mold runner:

The number and distribution of the flow channels should be reasonably designed according to the shape and size of the mold cavity and the fluidity of liquid silica gel. When designing the flow path of the LSR mold, it is necessary to consider the flow path and filling sequence of the material to ensure that the mold can achieve uniform filling and reduce the generation of bubbles. Reasonable flow channel layout can improve molding quality and production efficiency.

Temperature control of liquid silicone mold runner:

Liquid silicone needs to maintain a certain temperature range during the molding process to ensure its fluidity and molding quality. Therefore, the problem of temperature control needs to be considered when designing the flow path. The temperature of the liquid silicone can be precisely controlled by setting heating or cooling elements in the flow path.

Liquid silicone mold runner cleaning and maintenance:

When liquid silica gel flows in the flow channel, it may carry some impurities or residues, which may affect the molding quality of liquid silica gel. Therefore, when designing the runner, it is necessary to consider the cleaning and maintenance of the runner. The flow path surface of the LSR mold should be properly treated to reduce friction resistance and prevent material adhesion. Common treatment methods include polishing, sandblasting and coating.

What is the normal pressure for liquid silicone injection?

liquid silicone injection

Liquid silicone rubber injection molding is a complex process that requires precision and expertise to achieve the best results. Among the many factors that influence the success of this technology, pressure plays a critical role in ensuring material flow, mold filling and part quality. Let’s delve into the world of liquid silicone rubber injection molding and understand the dynamics of pressure to master this complex process.

The pressure in liquid silicone rubber injection molding refers to the force exerted on the silicone rubber material injected into the mold cavity. This pressure is typically measured in pounds per square inch (psi) or megapascals (MPa) and is carefully controlled throughout the molding cycle to achieve the desired result. Understanding the role of pressure and its impact on the molding process is critical for mold workers to ensure they are consistently producing high-quality parts.

In liquid silicone rubber injection molding, one of the primary functions of pressure is to facilitate the flow of silicone rubber material into the mold cavity. When liquid silicone rubber is injected into a mold, it encounters resistance from the mold walls and design features. The applied pressure helps overcome this resistance, ensuring even filling of the interior of the mold and preventing the development of air bubbles or voids in the finished part.

liquid silicone injection

The normal pressure for liquid silicone injection molding typically ranges from 1000 to 2000 psi (pounds per square inch), or approximately 6.9 to 13.8 MPa (megapascals). However, the specific pressure required may vary depending on factors such as the viscosity of the silicone material, the design of the mold, and the complexity of the part being molded. It’s essential to consult the manufacturer’s guidelines and recommendations for the particular silicone material and injection molding process being used to determine the optimal pressure settings. Additionally, experienced molders may adjust the pressure based on their expertise and the specific requirements of the molding project.

In addition, pressure also plays a crucial role in controlling the size and surface quality of molded parts. By adjusting injection pressure, mold workers can precisely control the flow rate and distribution of silicone rubber material within the mold cavity. This allows them to produce parts with precise dimensions, consistent wall thickness and smooth surfaces that meet the stringent part quality requirements of various industries.

For liquid silicone rubber injection molding, the optimal setting of pressure depends on several factors, including the viscosity of the silicone material, the design of the mold, and the complexity of the molded part. Higher viscosity materials may require higher injection pressures to ensure proper flow and filling, while lower viscosity materials may achieve satisfactory results at lower pressures. Likewise, molds with complex features or thin-walled parts may require higher pressures to achieve complete fill and avoid defects such as short shots or flash.

It is critical for molders to work closely with material suppliers and mold designers to determine the appropriate pressure settings for each molding application. This may involve conducting process trials and experiments to fine-tune injection parameters and optimize part quality. In addition, monitoring equipment such as pressure sensors and pressure gauges can provide real-time feedback of the molding process, allowing mold workers to make adjustments as needed to maintain consistency and accuracy.

In summary, pressure is a critical variable in LSR injection molding, affecting material flow, mold filling, and part quality. By understanding the dynamics of pressure and its impact on the molding process, mold workers can optimize operations and consistently achieve excellent results. Through careful control and precise adjustment, liquid silicone rubber injection molding offers endless possibilities for producing high-quality, complex parts for a variety of applications.
