Silicone umbrella valves have been a fixture in various industries since the early 1940s, finding applications in a range of critical functions such as outlet valve systems for cylinder-driven pump valves, vent valves for vehicle fuel tanks, and relief valves for piston and diaphragm pumping. These valves have also been integral components in check valves […]
Liquid silicone rubber injection molding (LSR) and liquid rubber over-molding (OLR) present distinct differences, particularly in their material delivery systems. While LSR employs a liquid injection mold, OLR utilizes a plastic gun for the injection process. In the case of LSR, the injection-molded tool is introduced to a specialized injection molding machine designed for […]
A Definition of Rubber Metal Dome Keypads: Dome-switch keyboards, a fusion of flat-panel membrane and mechanical-switch designs, integrate two circuit board traces beneath a rubber keypad. Upon key press, the dome collapses, connecting the circuit traces and facilitating character input. These keyboards utilize metal dome switches or polyurethane-formed domes (polydomes). Metal dome switches, crafted from […]
Securing an injection mold service for plastic pipe connectors is a critical step that can significantly impact the success of a project. Despite its often overlooked nature, the integrity of these pipes is integral to the overall functionality of a system. Any breakage or cracking can lead to widespread issues within the entire project. […]
Understanding the Polyurethane Rubber Keypad Protective Overcoat： Polyurethane serves as a protective layer covering the entirety of a rubber keypad, delivering wear resistance in high-usage scenarios. In some instances, it can enhance the abrasion resistance of graphics by up to 20 times. The application of a polyurethane protective overcoat reinforces the durability of rubber keypads, […]
Injection molding of optical lenses presents two primary options within the direct injection molding process. The traditional approach involves a drum press, powered by an electric motor. In this method, a molten object is rotated within a vacuum on a vertical drum that moves into the mold cavity, subjecting the object to pressure. A metal […]
Silicone rubber molding is a precision technique employed for shaping and fabricating silicone rubber components. This method utilizes a heated mold to compress or inject silicone rubber into a cavity, allowing it to take the desired form. The molding processes commonly used include injection molding, compression molding, and transfer molding. These processes are executed with […]
Liquid silicone gaskets play a crucial role in various applications due to their unique properties, distinguishing them from traditional latex-based seals commonly found in local appliance stores. While latex seals may encounter issues such as expansion, contraction, and sticking on hot radiators, liquid silicone offers a compelling alternative. Liquid silicone, also referred to as […]
