Liquid silicone overmolding with plastic is a process that has gained popularity in recent years due to its ability to produce high-quality, durable and flash free overmolded silicone products. This process involves the use of liquid silicone rubber (LSR) to cover and bond with a plastic substrate, creating a strong and reliable bond between the two materials.


One of the main advantages of liquid silicone overmolding with plastic is the ability to create complex shapes and designs. The LSR can be molded to fit around intricate parts of the plastic substrate, ensuring a tight and secure fit. This is particularly useful for products that require a high level of precision and accuracy, such as electronic components, medical devices or LED lighting components.


Another benefit of this process is the increased durability of the finished product. The LSR part provides a protective layer over the plastic substrate, preventing it from becoming damaged or worn over time. This makes it an ideal solution for products that will be exposed to harsh environments or frequent use.


In addition to its durability, liquid silicone overmolding with plastic also offers excellent resistance to temperature extremes. This makes it an ideal choice for products that will be used in outdoor or industrial settings, where exposure to harsh conditions is common.


The process of liquid silicone overmolding with plastic is relatively simple and straightforward. First, the plastic substrate is molded into the desired shape and design. Next, the LSR is injected into a mold that is designed to fit around the plastic substrate. The mold is then heated to cure the LSR and bond it to the plastic substrate.


YEJIA specializes in over-molding silicone with other materials to create products with superior performance. Silicone is a popular choice among people due to its environmentally friendly nature, softness, and non-toxicity. Its temperature range of -40 to 250 degrees Celsius is incomparable to plastic. Over-molding with metal or plastic can create new properties, resulting in a product that is both soft and hard.


Our team at YEJIA consists of 8 Japanese engineers with over 30 years of work experience in mold manufacturing management. They are skilled in making mold precision tolerance within 0.005 millimeters, and the R angle can be as low as 0.1 millimeters. This ensures that our silicone products are free from flash.


We operate from a modern workshop spanning 5000 square meters and equipped with 26 sets of LSR injection molding machines, 6 sets of horizontal LSR injection molding machines, and 6 sets of solid silicone vacuum compression molding machines. Our production workshop and spraying workshop are both rated at 100,000 class clean production levels. We specialize in over-molding silicone with a range of materials, including plastics, metal, PCB, fabric and so on. Our medical grade liquid silicone is Nusil imported from USA and is used in customized over-molding with plastic.
