The main production equipment for rubber end gaskets includes compression molding machines, flat vulcanizing machines, automated loading and unloading systems, and supporting mixing and post-processing equipment. These machines work together to complete the entire process from raw material processing to finished product molding, ensuring precise product dimensions and stable performance.
1. Compression Molding Equipment
- Flat Vulcanizing Machine: This is the core equipment for producing rubber gaskets. It uses heating and pressurization to vulcanize the rubber in a mold. Modern equipment often uses PLC control to achieve functions such as pre-compression, venting, pressure holding, vulcanization timing, and automatic mold opening.
- Fully Automatic Rubber Vulcanizing Machine: Integrates a CCD vision positioning system, achieving a consistency pass rate of up to 99.8% and pressure control accuracy of ±0.1MPa, suitable for high-precision sealing component production.
- Vacuum Flat Vulcanizing Machine: Creates a vacuum during vulcanization, effectively reducing internal air bubbles and increasing density. Suitable for industrial or medical-grade rubber parts with high quality requirements.
2. Raw Material Processing Equipment
- Internal Mixer/Open Mill: Used for the uniform mixing of rubber raw materials and additives to form a well-plasticized compound. The open mill also features adjustable roller spacing for easy control of the compound thickness.
- Cuter/Calendar: Calenders the compound into sheets or strips for pre-forming operations before molding.
3. Automated Auxiliary Systems
- Automatic Loading and Unloading Device: Used in conjunction with the vulcanizing machine to improve production efficiency and reduce labor costs.
- Quick Mold Change System: Features quick-release component designs to support flexible switching between multiple product specifications, adapting to the needs of small-batch, multi-variety production.
4. Post-Processing and Inspection Equipment
- Trimming Machine: Removes burrs and flash from vulcanized products, ensuring a clean appearance.
- Cooling System: Some vulcanizing machines integrate efficient cooling functions, shortening demolding time and improving operational efficiency.
- Quality Inspection Instruments: Includes hardness testers, tensile testing machines, and airtightness testers, used to verify whether the finished product performance meets standards.
