In terms of sealing performance, hydrogenated nitrile butadiene (HNBR) O-ring sealing kits rely on the axial or radial deformation of their cross sections in the assembled state to produce a sealing effect. Whether at rest or in motion, it can exert sealing effects in various fluid media (such as lubricating oil, hydraulic oil, fuel oil, water, chemicals, gases, etc.). Hydrogenated nitrile (HNBR) O-ring seal kits also offer good resistance to ozone, a wide range of chemicals, and radiation. This makes it widely used in automobiles, refrigeration, nuclear industry, and other fields. HNBR materials are processed through a special hydrogenation process to greatly reduce the number of unsaturated double bonds in their molecular chains, thus greatly improving their ozone resistance. Even after long-term exposure to ozone, HNBR O-ring sealing kits maintain stable physical and chemical properties, ensuring a durable sealing effect.

What are the special requirements for HNBR O-ring mold design? How to ensure the precision and durability of the mold?

Special requirements for HNBR O-ring mold design
Material adaptability design:
Corrosion resistance: HNBR material has a certain chemical corrosion to the mold material, so the mold material needs to choose alloy steel or stainless steel with high corrosion resistance to reduce the dimensional change and surface quality degradation caused by material corrosion during the use of the mold.
Coefficient of thermal expansion matching: HNBR will generate heat during the vulcanization process. The mold material must have good thermal stability and a thermal expansion coefficient similar to that of HNBR to avoid dimensional deviation caused by thermal expansion and contraction.
High-precision dimensional control:
Precision machining: hydrogenated nitrile butadiene (HNBR) O-ring sealing kits have extremely high dimensional accuracy requirements. The mold design needs to adopt precision machining technology, such as CNC (computer numerical control) machining, to ensure that the dimensions of each part of the mold are accurate and meet the high-precision requirements of the O-ring.
Tolerance management: Strictly control the tolerances in the mold manufacturing process to ensure that the mold can still maintain high precision during long-term use, which is crucial to ensure the sealing performance and assembly adaptability of the O-ring.
Complex shape processing capability:
Flexible design: For special application scenarios, such as extreme pressure, temperature or fluid media, HNBR O-rings may require special shape design, and the mold design needs to be highly flexible to adapt to the production needs of complex shapes and special structures.
Mold parting line design: Reasonable parting line design not only helps demolding, but also reduces product defects and improves the yield rate. For HNBR materials, the parting line needs to be specially designed to reduce material tearing and mold wear.
Efficient vulcanization process adaptability:
Temperature uniformity: The mold design needs to consider the temperature uniformity during the vulcanization process to ensure that the HNBR is evenly heated throughout the mold cavity to avoid local overheating and material performance degradation.
Fast heating and cooling: In order to improve production efficiency, the mold design needs to have the ability to heat and cool quickly to shorten the vulcanization cycle while ensuring product quality.
Measures to ensure mold accuracy and durability
Adopt advanced materials and processing technologies:
High-performance mold steel: Select mold steel with high strength, high hardness, high wear resistance and high thermal stability, such as P20, H13, etc., and heat treat it to enhance its performance.
Surface treatment technology: nitriding, carburizing, hard chrome plating and other surface treatment technologies are used to improve the hardness and wear resistance of the mold surface and extend the service life of the mold.
Precision manufacturing and testing:
High-precision processing equipment: Use high-precision equipment such as five-axis CNC machining center and wire cutting to process the mold to ensure the size and shape accuracy of the mold.
Strict quality inspection: After the mold is manufactured, use high-precision inspection equipment such as three-coordinate measuring instrument and projector to conduct comprehensive inspection to ensure that the size and shape of the mold meet the design requirements.
Mold maintenance and care:
Regular cleaning and lubrication: Clean the mold regularly to remove residual rubber materials and impurities, and lubricate the sliding parts to reduce wear.
Wear monitoring and repair: By regularly checking the wear of the mold, timely discover and repair the worn parts to prevent the wear from expanding and affecting the accuracy and life of the mold.
Technological innovation and industry-university-research cooperation:
Technology iteration: Relying on the industry-university-research cooperation with many domestic universities and scientific research institutions, the company continuously introduces new technologies and new materials to optimize mold design and improve mold performance.
Patent support: The company uses its three existing invention patents and more than 30 utility model patents to continuously promote innovation in mold design and manufacturing technology, ensuring that the precision and durability of the molds are in the leading position in the industry.
