Product Description Product DescriptionImmerse yourself in the exceptional world of customization with Ningbo Zhongmu Rubber Products Co., Ltd, where every rubber product is a masterpiece of precision and adaptability. Our meticulous, comprehensive process ensures that each rubber product is crafted with unparalleled attention to detail, tailored to meet your exact specifications. From selecting superior materials to optimizing performance and fine-tuning process parameters, our products are shaped by the pinnacle of industry standards:1. Raw Material Preparation and Pretreatment1. Main Material SelectionSelect the perfect type of raw rubber to suit your product's unique purpose. Whether you require the exceptional elasticity of natural rubber, the oil resistance of nitrile rubber, or the extraordinary high-temperature resilience of silicone rubber, our extensive selection ensures that your needs are beautifully met.2. Compound Agent DispensingElevate the performance of rubber by meticulously dispensing vulcanizers such as sulfur or peroxide, enhancers, anti-aging agents, and fillers like carbon black or white carbon black. This process achieves unparalleled precision with a narrow error margin of merely 0.1%, ensuring reliability and excellence in every product.3. Treatment of Reinforcement MaterialsTo ensure impeccable binding strength, skeletal materials, whether steel wire or fiber, undergo a meticulous pretreatment process. This involves soaking in rubber and drying at a precise temperature range of 60-70°C, allowing for seamless integration with the rubber.2. Plastic Refining ProcessBoost the plasticity of rubber by reducing its molecular weight through advanced mechanical extrusion or thermal oxidative degradation. Cutting-edge equipment like opening and compacting machines are employed to perfect this process, ensuring superior quality.1. Mechanical Plastic Smelting: Maintain a precise 60°C to effectively reduce viscosity to below 60, ensuring smooth, seamless processing.2. Thermoplastic Refining: Ideal for natural rubber pretreatment, this method utilizes compressed air to achieve outstanding results.3. Mixed Refining ProcessAchieve unmatched consistency in properties by uniformly dispersing the mixture in a high-performance rubber refining machine, creating a mixed rubber of exceptional quality and uniformity.Key control points: Maintain a precise temperature of ≤120°C, with a duration of 5-15 minutes, and a meticulously set roll distance of 1-3mm, ensuring perfect results every time.Customized adjustments:1. For products requiring extraordinary wear resistance, boost carbon black content to 40-50 parts by weight, significantly enhancing durability.2. For products that must endure high temperatures, incorporate zinc oxide (5-8 parts by weight) along with a silane coupling agent to achieve superior performance.3. For the moulding process:Placement formingSuitable for rubber plates and sealing strips, it is necessary to control the adhesive thickness tolerance within ± 0.1mm.Extrusion and shapingFor the hose and sealing ring, the design of the mouth die directly affects the accuracy of the section.Modular pressure moldingMetal-rubber composite molds should be used for complex structures.Injection moldingComplex structural parts are multi-material composite componentsDetailed PhotosProduct ParametersComparison of key performance parametersindexNRNBRFKMSIREPDMTemperature resistance range-60~100oC-25~130oC-20~250oC-70~300oC-60~150oCoil resistivity insufficientexcellent(NBR40)extremely excellentinsufficientinsufficientozone resistanceinsufficientinsufficientexcellentexcellentexcellentabrasion performanceexcellentmiddlemiddleinsufficientexcellentElectric insulationexcellentinsufficientinsufficientexcellentexcellentSuggestions for type selectionOil resistance sceneNitrile rubber (NBR) or fluorine rubber (FKM) is preferredhot environment Silicone rubber (VMQ) or fluorine rubber (FKM)resistance to chemical attack Chlorosulfated polyethylene (CSM) or fluorine rubber (FKM)dynamic packingEthpropylene rubber (EPDM) or polyurethane rubber (PU)Packaging & Shipping Company Profile FAQ
