1. Raw Material Preparation and Pretreatment
1. Main Material Selection
Choose your perfect match from our diverse range of high-quality rubbers. Whether you need natural rubber for its superior elasticity, nitrile rubber for unparalleled oil resistance, or silicone rubber for its remarkable heat resistance, we tailor our selection to your product's unique demands.
2. Compound Agent Dispensing
Achieve unparalleled performance with precision. Our meticulous process involves the addition of vulcanizers (sulfur or peroxide), promoters, anti-aging agents, and fillers like carbon black. Each ingredient is measured with exactitude, ensuring customization perfection with a tolerance of just 0.1%.
3. Treatment of Reinforcement Materials
Empower your product with robust reinforcement. Our process involves soaking skeletal materials like steel wire or fiber in rubber, then drying them at 60-70°C. This enhances binding strength, ensuring durability and performance that stands the test of time.
2. Plastic Refining Process
Unlock the potential of raw glue with our advanced plastic refining techniques. By employing mechanical extrusion or thermal oxidative degradation, we expertly lower molecular weights, enhancing plasticity and ensuring a superior end product.
1. Mechanical Plastic Smelting: Maintain a precise 60°C, while expertly reducing viscosity to optimal levels below 60.
2. Thermoplastic Refining: Tailored for natural rubber pretreatment, infuse the process with compressed air for refined quality.
3. Mixed Refining Process
Embrace consistency with our sophisticated blending process. By ensuring a uniform distribution in the rubber refining machine, we create mixed rubber that boasts uniform attributes, setting new standards in quality.
Focus on these crucial control points: maintain a temperature under 120°C, adhere to a process time of 5-15 minutes, and keep roll distances between 1-3mm for optimal results.
Customized adjustments:
1. For high wear-resistant excellence: Elevate carbon black contents to a robust 40-50 parts by weight.
2. For high temperature resilience: Integrate zinc oxide (5-8 parts by weight) and a silane coupling agent to withstand extreme conditions.
3. For the moulding process:
| Placement forming | Suitable for rubber plates and sealing strips, it is necessary to control the adhesive thickness tolerance within ± 0.1mm. |
| Extrusion and shaping | For the hose and sealing ring, the design of the mouth die directly affects the accuracy of the section. |
| Modular pressure molding | Metal-rubber composite molds should be used for complex structures. |
| Injection molding | Complex structural parts are multi-material composite components |
Explore the unique characteristics of our premium rubber materials
| native rubber(NR) | High elasticity (tensile strength 20-25MPa), wear resistance, tear resistance, but poor oil resistance and ozone resistance |
| styrene-butadiene rubber(SBR) | Excellent wear resistance (low cost), but the elasticity, tear resistance is weaker than natural rubber |
| butadiene rubber(BR) | Outstanding cold resistance (-70ºC is still elastic), wear resistance, but low strength, poor tear resistance |
| Ding eyes rubber(NBR) | Excellent oil resistance (mineral oil, lubricating oil), low compression permanent deformation, but poor low temperature resistance |
| ethylene-propylene rubber(EPDM) | Optimal weather resistance, ozone resistance, high temperature resistance (150ºC), good electrical insulation, but poor oil resistance |
| chloroprene rubber(CR) | Good aging resistance, ozone resistance and flame retardant, but poor low temperature performance (brittle below-30ºC) |
| silastic(VMQ) | Temperature resistance range (-70~300ºC), excellent biocompatibility, but low mechanical strength |
| fluorine(-containing)rubber(FKM) | High temperature resistance (250ºC), strong acid and alkali resistance, oil resistance, but poor air permeability, high processing difficulty |
| hydrogenated butadiene-acrylonitrile rubber (HNBR) | Oil resistance, high temperature resistance is better than ordinary NBR, wear resistance is strong |
| chlorosulfonated polyethylene(CSM) | Resistance to strong acid and strong alkali (such as concentrated sulfuric acid), ozone resistance, but poor oil resistance |
