Our company's expertise in close tolerance injection plastic molding, as well as our extensive knowledge of micromolding materials, enables us to advance the envelope of polymer science. Micromolding is one of the most difficult injection molding processes. In essence, the polymers used have "macromolecules". Handling these molecules at the tiny sizes required for micromolding is tricky because they often behave differently than they would normally do in larger applications. And, while all injection molding processes require strict tolerances, this is especially true in micromolding; Even the tiniest size change can make a part of this size unusable. Due to the unique and specialized nature of micromolding processes, we have to design new micromolding solutions for almost every project we undertake. Micromolding of very small parts naturally requires very small molds and tools. Because some of the mold pins, tool parts, etc., are only a few thousandths of an inch in diameter, even the metals we use in the mold become very fragile. Our molds and tools are manufactured using special micro-mold sources to ensure high quality and durability.

Existing valve in the body, the valve cover and the components are intact, only a slight deformation or corrosion of the sealing surface, the valve can not be used. Repair these valves non-professional factory does not work, resulting in great waste. Therefore, the valve unit is expected to use is: valve seat, valve plate sealing surface is not easy to deformation, corrosion-resistant, vulnerable sealing material can be changed. Valve plate in the opening and closing with the sealing surface do not have friction or minimize friction. First, the purpose of the invention: to solve the valve seat and valve plate sealing surface corrosion or deformation, the valve plate can automatically compensate and pressure sealing surface and valve and valve pressure balance automatically solve the problem of soft sealing material by friction and damage the seal Surface problems, due to the sealing of the valve can be changed, greatly increasing the use of the valve. Second, the practical range: diameter φ50-φ400mm, pressure 2.5-4.0MPa, less than 200 ℃ of various liquid at room temperature Third, the technical solutions: The valve is a double parallel gate valve, inlet seal, the inlet valve plate from the gland and Force relief valve plate composed of the main seal gate. The sealing sleeve moves synchronously with the unloading valve plate but it is not connected. The pipe pressure is transmitted to the valve seat on the outlet side through the unloading valve plate and the leveling arm, which greatly improves the bonding force of the soft sealing surface. The valve plate is covered with a corrosion-resistant rubber gland. Soft sealing material in the process of opening and closing, with the valve seat to maintain a certain distance, so that the soft sealing material in non-friction non-pressure environment work. The gland isolates the fluid being delivered in the pipe from the parts inside the spool to protect it from fluid corrosion and impurities. This valve sealing material replacement is very convenient, so the service life is more than 5 times the general valve. More Keyword Search: Combination Valve
