Precision Medical Instruments - "Structural Components of Frozen Slicers"

To quickly detect the pathological tissue of acute patients, low-temperature cell slice analysis instruments are used to quickly analyze the morphological and structural changes of cells and tissues, and determine the nature of the lesion as soon as possible. Therefore, the thickness and accuracy of cell tissue slices directly affect the diagnostic level and accuracy. With the development of precision medicine, the application of intraoperative and postoperative frozen sections is becoming increasingly common and demanding. The thickness of frozen slicers produced domestically in China is 2-3 micrometers with an accuracy of 0.5 micrometers, while the thickness of frozen slicers produced in Germany can reach 1 micrometer with an accuracy of up to 0.2 micrometers. The accuracy of medical equipment is one of the reasons for the difference in our medical level compared to developed countries.

In recent years, Shanghai Aweite Precision Machinery Co., Ltd. has established a dedicated technical research team to focus on the manufacturing process difficulties of precision medical instruments. Breakthroughs have been made in key manufacturing technologies such as low-temperature micrometer propulsion mechanisms. This technology effectively ensures the cutting accuracy and thickness of frozen cell slicers, achieving a slice thickness of 1 micrometer and an accuracy of 0.1 micrometer, replacing imported products from Germany. It has now been exported to Germany and the United States, Due to the advantage of manufacturing costs, the core components of the customer's product have completely shifted from German production to mass production by the company.

Achievements: The technical products of this project have been implemented and applied in industries such as medical, precision instruments, semiconductors, communication, and industry in China, and approximately 3.5 million sales contracts have been signed.

Metal materials - Pipeline cement weight coating (40mm50mm60mm70mm80mm90mm100mm110mm120mm 130mm)

The commonly used counterweight concrete for pipelines poses certain technical difficulties in achieving sustainable strength growth and long-term resistance to seawater erosion in the later stage. And commonly used weight concrete has a longer curing cycle and high economic cost.

In this regard, Hailong Pipeline Engineering Technology Service Co., Ltd. has carried out technical research to investigate the impact of key components such as electric furnace steel slag aggregate and cementitious system on the key performance of pipeline weight concrete; The influence of aggregate characteristics, especially gradation and sulfur content, on the key performance of pipeline weight concrete; Research on the production process control technology of pipeline weight concrete under special environments such as water maintenance, summer and winter, and ultimately form the key technology research of pipeline weight concrete.

Achievements: The performance indicators such as cube compressive strength, core compressive strength, bulk density, and water absorption of counterweight concrete studied in this achievement meet the acceptance technical indicators of counterweight concrete, and adopt the mode of "research, promotion, and production at the same time".

High temperature alloy preparation technology - nickel based alloy bars for nuclear power use

(UNSN06690, 690, NC30Fe)

The large size specification of the bar required for the shear cover of the blasting valve means that from the beginning of smelting, the specification of the steel ingot is larger, and the difficulty of smelting quality control and hot working forming control increases. Therefore, the research content of this project always revolves around many problems caused by "large", including defects in the solidification process and the formation of macroscopic and microscopic non-uniformity, as well as the forced homogenization method, internal organizational changes and surface quality improvement during hot working Heat treatment process and control of uniformity of microstructure and properties.

Achievements achieved: Through research by Baowu Special Metallurgy Co., Ltd., a composition system that meets the requirements of nuclear power technology and is suitable for manufacturing processes has been formed. Various process difficulties have been overcome, such as pure purification smelting and precise control of N06690 special alloy large steel ingots, homogenization manufacturing of large electroslag ingots, hot processing and forming of large-sized bars, and control of heat treatment microstructure and performance uniformity. The large-sized bars for shear covers of nuclear power blasting valves have been successfully developed, The organization and performance of the products all meet the requirements of nuclear power procurement technology standards, forming a full process manufacturing technology with independent intellectual property rights from smelting to heat treatment.

Key Automotive Components - High Voltage Wiring Harnesses for New Energy Vehicles

(100000108, 100000451, 100000346, 100000370, 100000738, 100001307, 100000851, 100000852)

In new energy vehicles, the high-voltage system is one of the core components, which plays a very important role as a medium for interconnecting various components in the high-voltage system. Due to the characteristics of high voltage, high current, heat resistance, and durability of the high-voltage wiring harness, the high-voltage wiring harness is generally designed to be thick (copper cable) and thick (insulation material). Moreover, the high-voltage wiring harness works in high-temperature vibration environments for a long time, and the wiring harness is prone to deformation and fatigue, Affects the normal operation of the wiring harness.

Achievements: The high-voltage wiring harness of new energy vehicles developed by Shanghai Jinting Automotive Wiring Harness Co., Ltd. belongs to the high-voltage power system of pure electric passenger vehicles, mainly responsible for transmitting the energy of the power battery to various high-voltage electrical equipment in the power system. The high-voltage wiring harness used has been strengthened compared to ordinary wiring harnesses in terms of waterproof performance, voltage resistance insulation, electromagnetic shielding, etc. It can ensure the important function of high-voltage and high current transmission, and also ensure that the product is durable, safe, and reliable in harsh automotive environments.
