Achieve the effect of opening the outlet on the caster as the piston rod moves down

As vacuum pressure increases, material is drawn into the piston cylinder through small holes on either side of the hopper, enabling the suction process. Once the hopper is fully filled, the material is compressed, and the ejector is closed. A small ball at the outlet opens the discharge mechanism, allowing the material to flow out. As the piston rod moves downward, the small holes on both sides of the casting device are sealed, disconnecting the piston cylinder from the hopper. At this point, the material can exit through the periphery of the ball via the lower outlet of the pouring device, completing the controlled extrusion process. The spring mechanism prevents the piston from moving further, while the vacuum pump ball blocks the lower outlet of the oscillating device, ensuring smooth material flow and maintaining one-way closure. The design of the molding structure has transformed the rotary valve's switching action into a spring-actuated float control system. This not only simplifies the mechanical layout but also reduces the number of moving parts and the complexity of the transmission system. The concept behind the pouring sandwich spring float forming mechanism was developed to meet the growing demand for innovative food products, particularly those with double stuffing or multi-layer puffing. It also considers the preferences of consumers who enjoy softer textures. Based on analysis, reference, and adaptation, a new design principle for the sandwich casting structure was created. The core idea revolves around soft materials that adhere easily and require precise extrusion. This approach allows parallel sandwich extrusion from two cylinders in a twin-screw system, where the outer casing is filled with an inner stuffing. In the case of a three-cylinder setup, the parallel output enables wrapping of two different fillings. The spring floating ball mechanism is applied here as well, incorporating the limit switch control principle used in electrical circuits to manage the extrusion process effectively. By integrating these three key concepts—spring float control, parallel extrusion, and limit switch logic—a new pouring spring float double sandwich forming mechanism was designed. This innovation enhances efficiency, precision, and versatility in food processing, making it ideal for modern, complex food manufacturing needs.

HK9 Glass Dome Lens

Dome lenses are hemispheres. The two optical surfaces are an equal thickness apart, creating a naturally strong shape that gets tougher under pressure. This makes dome windows ideal for underwater environments and in applications such as camera dome ports and submersible windows.
BK7 or K9L domes are used primarily in meteorology applications. BK7 offers excellent transmission from 300nm up to 2µm. BK7 is a relatively hard material, with excellent chemical durability.
UV fused silica domes ( JGS1 ): For applications operating in the deeper UV range, we offers a range of UV fused silica domes. Fused silica domes are commonly used in underwater applications at extremely high pressures.

Sapphire domes: For infrared applications we can provide sapphire domes. Sapphire is an extremely hard material with transmission of over 80% in the 2-5µm wavelength range. As with fused silica, sapphire is able to withstand extreme pressures, making it the perfect material for underwater camera and missile fairing applications.
