Product Description Product DescriptionThe customization process for rubber products is a systematic approach to processing rubber materials tailored to product requirements. It encompasses material selection, performance optimization, and the adjustment of process parameters. The following outlines the core processes and technical aspects, as informed by industry practice:1. Raw Material Preparation and Pretreatment1. Main Material SelectionDepending on the product's intended use, select the appropriate type of raw rubber, such as natural rubber (for high elasticity), nitrile rubber (for oil resistance), silicone rubber (for high temperature resistance), etc.2. Compound Agent DispensingAdd vulcanizer (sulfur or peroxide), promoter, anti-aging agent, filler (carbon black or white carbon black), etc., and customize the performance by accurate weighing (with an error of 0.1%).3. Treatment of Reinforcement MaterialsThe skeletal material (steel wire or fiber) should be pretreated by soaking in rubber and drying at 60-70°C to enhance the binding strength with the rubber.2. Plastic Refining ProcessLower the molecular weight of the raw glue through mechanical extrusion (using an opening machine) or thermal oxidative degradation (using a compacting machine) to improve plasticity.1. Mechanical Plastic Smelting: Maintain a temperature of 60°C and reduce the viscosity to below 60.2. Thermoplastic Refining: Suitable for natural rubber pretreatment, introduce compressed air.3. Mixed Refining ProcessUniformly disperse the mixture in the rubber refining machine to form a mixed rubber with consistent properties.Key control points: temperature (≤120°C), time (5-15 minutes), and roll distance (1-3mm).Customized adjustments:1. For high wear-resistant products: increase the carbon black content to 40-50 parts by weight.2. For high temperature resistant products: add zinc oxide (5-8 parts by weight) and a silane coupling agent.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 Parameters Comparison of key performance parametersindexNRNBRFKMSIREPDMTemperature resistance range-60~100oC-25~130oC-20~250oC-70~300oC-60~150oCoil resistivity insufficientexcellent(NBR40)extremely excellentinsufficientinsufficientozone resistanceinsufficientinsufficientexcellentexcellentexcellentabrasion performanceexcellentmiddlemiddleinsufficientexcellentElectric insulationexcellentinsufficientinsufficientexcellentexcellentPackaging & ShippingInstallation InstructionsSuggestions 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) Company ProfileOur AdvantagesFAQ
