1. Meticulous Preparation and Pretreatment of Raw Materials
1. Discerning Main Material Selection
Select the optimal type of raw rubber designed to align seamlessly with your product's function. Whether you seek the outstanding elasticity of natural rubber, the superior oil resistance of nitrile rubber, or the extraordinary high-temperature resilience of silicone rubber, our selection provides the best of the best.
2. Precise Compound Agent Dispensing
Elevate the rubber's performance by accurately incorporating vulcanizers such as sulfur or peroxide, promoters, anti-aging agents, and fillers like carbon black or white carbon black. Achieve unparalleled precision with an exceptionally low error margin of a mere 0.1%.
3. Comprehensive Treatment of Reinforcement Materials
To ensure optimal binding strength, the skeletal material, be it steel wire or fiber, undergoes meticulous pretreatment. This involves immersion in rubber followed by precise drying at 60-70°C, resulting in superior integration with the rubber.
2. Advanced Plastic Refining Process
Improve plasticity by diminishing molecular weight using cutting-edge mechanical extrusion or thermal oxidative degradation techniques. State-of-the-art equipment such as innovative opening and compacting machines are employed for this process.
1. Mechanical Plastic Smelting: Maintain a precise temperature of 60°C to effectively lower the viscosity below 60, ensuring seamless processing.
2. Thermoplastic Refining: Ideally suited for natural rubber pretreatment, this method utilizes compressed air to achieve exceptional results.
3. Superior Mixed Refining Process
Attain impeccably consistent properties by uniformly dispersing the mixture in a high-performance rubber refining machine, producing a mixed rubber of unparalleled quality.
Essential control points: Maintain a precise temperature of ≤120°C, with a time frame of 5-15 minutes, and meticulously adjust the roll distance to 1-3mm.
Customized Adjustments for Excellence:
1. For products requiring exceptional wear resistance, elevate the carbon black content to 40-50 parts by weight for enhanced durability.
2. For products that must withstand high temperatures, incorporate 5-8 parts by weight of zinc oxide along with a silane coupling agent for optimal performance.
3. During 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 |
