In the production process of rubber products, silicone vulcanization is a crucial step that directly affects the performance, appearance, and service life of the product. The temperature and time of silicone vulcanization are the two core parameters of the vulcanization process, and their selection principles are crucial for ensuring product quality.
1、 The basic principle of silicone vulcanization
Silicone vulcanization, also known as the cross-linking reaction of silicone rubber, refers to the process in which linear or branched silicone rubber molecules are cross-linked through chemical bonds under the action of a vulcanizing agent to form a three-dimensional network structure. Vulcanized silicone rubber has excellent heat resistance, cold resistance, weather resistance, electrical insulation, and chemical stability, and is widely used in fields such as electronics, electrical appliances, automobiles, and medical care.
2、 Principles for selecting the vulcanization temperature of silicone gel
1. Material characteristics: Different types of silicone materials have different vulcanization characteristics, so when selecting the vulcanization temperature, factors such as thermal stability, crosslinking density, and vulcanization speed of the material need to be fully considered. Generally speaking, silicone materials with good thermal stability can choose higher vulcanization temperatures to improve production efficiency; Silicone materials with lower cross-linking density require a lower vulcanization temperature to prevent excessive cross-linking from causing a decrease in product performance.
2. Type of vulcanizing agent: The type and amount of vulcanizing agent have a significant impact on the selection of vulcanization temperature. Different vulcanizing agents have different activation energies and vulcanization rates, so when selecting the vulcanization temperature, it is necessary to adjust it according to the type and amount of vulcanizing agent. For example, silicone materials using peroxide vulcanizing agents usually choose lower vulcanization temperatures due to their faster vulcanization rate; For silicone materials using sulfur vulcanizing agents, a higher vulcanization temperature can be chosen.
3. Product thickness: The thickness of the product is also one of the factors to consider when selecting the vulcanization temperature. Thicker products require a lower vulcanization temperature due to slower heat transfer to ensure uniform vulcanization inside and outside the product; Thinner products can choose higher vulcanization temperatures to improve production efficiency.
4. Equipment and process conditions: Equipment and process conditions also have a certain impact on the selection of vulcanization temperature. For example, the heating method and temperature control accuracy of the vulcanization equipment, as well as the thermal conductivity of the mold, can all affect the selection of vulcanization temperature. Therefore, when selecting the vulcanization temperature, it is necessary to consider the actual situation comprehensively.

3、 Principles for selecting the vulcanization time of silicone gel
1. Degree of vulcanization: The degree of vulcanization of silicone is the main basis for selecting the vulcanization time. The vulcanization time is too short, the product is not sufficiently vulcanized, and the performance does not meet the standard; If the vulcanization time is too long, it may lead to excessive cross-linking of the product and a decrease in performance. Therefore, when selecting the vulcanization time, it is necessary to set it reasonably according to the performance requirements of the product.
2. Sulfurization temperature: Sulfurization temperature is closely related to vulcanization time. A higher vulcanization temperature can shorten the vulcanization time and improve production efficiency; However, excessively high temperatures may lead to a decrease in product performance. Therefore, when selecting the vulcanization time, comprehensive consideration should be given to the vulcanization temperature.
3. Product thickness and shape: The thickness and shape of the product also affect the choice of vulcanization time. Thicker products require longer vulcanization time due to slower heat transfer; And for products with complex shapes, due to the temperature gradient during the vulcanization process, it is also necessary to extend the vulcanization time appropriately to ensure uniform vulcanization inside and outside the product.
4. Equipment and process conditions: Equipment and process conditions also have a certain impact on the selection of vulcanization time. For example, the heating method and temperature control accuracy of the vulcanization equipment, as well as the thermal conductivity of the mold, can all affect the setting of the vulcanization time. Therefore, when choosing the vulcanization time, it is necessary to consider the actual situation comprehensively.
4、 Summary
The selection principle of silicone vulcanization temperature and time is one of the key factors to ensure the performance and quality of rubber products. When selecting the vulcanization temperature and time, it is necessary to fully consider factors such as material characteristics, type of vulcanizing agent, product thickness, equipment and process conditions, and make reasonable settings based on the performance requirements of the product. By selecting the appropriate vulcanization temperature and time, the vulcanization process parameters can be optimized to improve the performance and quality of rubber products.

Liquid Silicone Rubber (LSR) encapsulation secondary molding is a precision manufacturing process that involves injecting liquid silicone rubber onto a pre formed plastic part or other substrate. Tolerance control is crucial for ensuring product quality and performance. Here are some general guidelines on tolerances:

During the encapsulation process, liquid silicone gel is injected or poured onto the substrate that needs to be encapsulated, and after curing, it forms a protective layer or connecting layer. Secondary molding, on the other hand, refers to the injection or casting of liquid silicone gel on top of the existing layer of silicone gel on the substrate to achieve more complex structures or functions.

In this process, tolerance control has become a crucial factor. Excessive tolerance may result in liquid silicone not being able to fully cover the corners or gaps of the substrate, leaving a hidden risk of adhesive leakage; The tolerance is too small, and it may also be difficult to form or cause product deformation due to insufficient fluidity of silicone.

So, what is the tolerance control range for the secondary molding of liquid silicone encapsulation? This actually depends on multiple factors, including the viscosity of silicone, injection or casting pressure, shape and size of the substrate, ambient temperature, etc. But generally speaking, we can consider the following aspects:

1、 Viscosity of silicone gel
The viscosity of silicone directly affects its fluidity. Silicone with low viscosity has good fluidity and is easy to fill the corners and gaps of the substrate, but it is also prone to overflow due to excessive fluidity. Therefore, when choosing silicone, it is necessary to select the appropriate viscosity based on the specific application scenario and requirements.

2、 Pressure for injection or pouring
The pressure of injection or pouring is a key factor affecting the filling effect of silicone gel. If the pressure is too low, silicone may not be able to completely fill the gaps in the substrate; Excessive pressure may lead to silicone overflow or product deformation. Therefore, in practical operation, it is necessary to adjust the injection or pouring pressure reasonably according to factors such as the shape and size of the substrate, the viscosity of the silicone gel, etc.

3、 Shape and size of substrate
The shape and size of the substrate have a direct impact on tolerance control. For substrates with complex shapes and high dimensional accuracy requirements, tolerance control needs to be more stringent. In this case, it may be necessary to use higher precision molds and stricter process control to ensure the filling effect of silicone.

4、 Environmental temperature
The ambient temperature has a significant impact on the curing speed and flowability of silicone gel. In high temperature environments, the curing speed of silicone increases and its flowability decreases, so it is necessary to increase the tolerance appropriately to ensure that silicone can completely fill the substrate. On the contrary, in low-temperature environments, the curing speed of silicone gel slows down and its flowability increases, so it is necessary to reduce the tolerance appropriately to prevent silicone gel from overflowing.
Based on the comprehensive consideration of the above factors, we can derive a rough tolerance control range. However, it should be noted that this is only a reference range and not an absolute standard. In practical operation, flexible adjustments need to be made according to specific situations.
To ensure proper tolerance control of the secondary molding of liquid silicone encapsulation, we can take the following measures:
1. Strengthen raw material testing to ensure that the silicone used meets quality requirements;
2. Regularly maintain and upkeep the mold to ensure its accuracy and stability;
3. Strictly control the pressure and time of injection or pouring to ensure that the silicone can evenly and fully fill the substrate;
4. Strictly control the production environment to ensure that parameters such as temperature and humidity meet production requirements;

5. Strengthen product quality testing, promptly handle and provide feedback on non-conforming products.
Please note that these are only general guiding principles. In the actual production process, adjustments and optimizations should be made based on specific product design, material characteristics, and production processes to achieve the best results. If you need detailed recommendations for specific products, please provide more information for more accurate assistance.
