    About Projects

    Mulan MFG received a request from a long-term cooperation customer, inviting us to participate in the manufacture of this precision plastic gear. This is a product that will participate in the exhibition. It is the main rotating gear bearing of a medical device. The maximum error is ±0.05mm, the minimum accuracy is ±0.012mm, the material is POM, good operation requires high-precision cutting and manufacturing, and the surface is smooth and free of burrs, and because of the characteristics of the material, it must always be kept clean. Mulan MFG has manufactured many POM CNC prototypes and high-volume products, and has extensive production experience.

    In the verticality, each gear is specially designed to achieve different functions. At the end of the shaft is a fixed groove, which is designed as a starting point. The design of the plane on both sides will drive the rotation of the mating parts, so it must be kept horizontal. There are two steps above the shaft that need to be fixed on the bearing. The outer diameter tolerance is -0.012mm. For plastic parts, this tolerance is very strict. Below the gear is a fixing groove for fixing at the position specified by the device. At the other end of the product, there is a need to be fixed on the sensor, so inside the gear is a space, how the size is seamlessly connected, The product is a hollow structure, used to collude with the data line, and pops up the sensor contact at the end of the shaft. The product’s running state is slow, with a speed of 5 revolutions per second, but for each function driven by each tooth It is very critical, so this requires all angles and concentricity to be accurate.

    About Products

    Choose expensive high-quality POM raw materials, use 3D design models to simulate all processes, expensive raw materials do not allow us to make a little mistakes. The product has a total of 71 key dimensions, and the gears and shafts are the key parts. The raw materials are processed into prototypes first, and 3 precision toolings are customized to be reversed and fixed. The product design is very large in size and is critical. Be very careful when reversing. The gear part of the product is formed by one-time processing. The processing is divided into three parts. The middle hole part needs two CNC turning processes. The end hole tolerance is ±0.03mm. Mulan MFG After 7 days Time to process 150 products smoothly, perfect appearance, won praise from customers, and made many important orders at the exhibition.

    About The Application

    Applied in the core part of the equipment of medical devices, it is responsible for penetrating the contacts of the sensor, and can run different functions of the product during the rotation process. Mulan MFG has rich production experience for the manufacture of medical products. And Chinese medical companies supply metal and plastic medical device parts.
