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, we also need to pay attention to the fluidity of silica gel, select the appropriate silica gel material, and adjust the hardness and viscosity of silica gel according to product requirements to ensure that its fluidity and filling performance are good.
In addition to the mold and injection process, the choice of raw materials is also a key factor affecting the size of the parting line. We should choose silicone rubber materials with good fluidity and fast curing speed, which helps to reduce the formation of parting lines. We also need to pay attention to the proportion of raw materials and processing technology to ensure that there will be no bubbles, cracks and other defects in the curing process of silicone products, so as to reduce the generation of parting lines.
Finally, the post-treatment process is also an important means to reduce the size of the parting line. After the silicone rubber products are formed, post-treatment processes, such as trimming, grinding or cutting, can be used to further reduce the size of the parting line and make it more detailed. This requires the use of professional tools and equipment, such as knives, sandpaper, polishing machines, etc., which requires high manual operation. For mass production, consider using an automatic polisher or other equipment to improve efficiency.
To sum up, in order to make the parting line of silicone rubber products more delicate, we need to start from the design and production of the mold, the injection process, the selection of raw materials and the post-treatment process, etc., the parting line refinement can also improve the market competitiveness of silicone products. With the continuous improvement of consumer requirements for product quality and appearance, the market demand for high-quality silicone products is also increasing.
