    Industrial Rubber Components Manufacturer
      1. R&D Team
      2. R&D Team Led by company founder Mr. Zhao Huijiang, a UK Chartered Engineer and IET member, the R&D team has over two decades of deep industry experience. Mr. Zhao is a specialist in material formulations, rubber diaphragm design, and accumulator engineering.
      1. Product Design
      2. Product Design During the product design phase, Simker employs advanced Computer-Aided Design (CAD) and Computer-Aided Engineering (SOLIDWORKS) tools to perform structural simulation and analysis, ensuring optimal dimensions and geometry while maintaining required performance standards.
      1. Quality Control
      2. Quality Control The company has obtained ISO 9001 quality management system certification and established enterprise standards filed with the Bureau of Quality and Technical Supervision.

    The service life primarily depends on the material, formulation, and operating environment.

    Provide the matching equipment model, diaphragm drawing, working conditions, technical standards, material requirements, and any industry certification to avoid mismatching.

    Graphene enhances high-temperature resistance, broadens the operational temperature range, improves aging resistance, and extends service life, enabling reliable performance under complex environmental conditions.

    Simker’s diaphragms help avoid costs associated with frequent replacements, downtime losses, and reduced operational efficiency, minimizing lifecycle expenses and production risks.

    Mining diaphragms incorporate graphene dispersion and nano-modification technologies, providing high strength, toughness, wear and corrosion resistance, and improved tear, fatigue, and thermal stability.
