How to control the thickness and width of the plate/sheet during production to meet the needs of different customers?
In the plate/sheet extrusion production process, controlling the thickness and width is a key link to ensure product quality and meet customer needs. Here are some commonly used methods and techniques:
1. Accurate mold design
Mold specifications: The design and manufacture of the mold directly affect the thickness and width of the plate. Accurate mold size and surface treatment can ensure the consistency of the extruded product.
Adjusting the mold gap: By adjusting the gap of the mold, the thickness of the extruded material can be controlled. Reasonable gap setting can ensure uniform flow of materials and reduce thickness fluctuations.
2. Temperature and pressure control
Heating temperature: By accurately controlling the temperature of the barrel and mold, the fluidity and molding effect of the material can be affected, thereby controlling the thickness.
Extrusion pressure: Adjusting the pressure of the extruder helps to improve the flow characteristics of the material, ensure uniform molding and control the thickness.
3. Speed regulation
Extrusion speed: The speed of the extruder has a direct impact on the thickness of the product. According to the material characteristics and production needs, adjust the extrusion speed to obtain the desired thickness and width.
Cooling rate: After molding, the cooling rate also affects the dimensional stability of the sheet. Proper cooling can reduce deformation and thickness variation.
4. Online monitoring and feedback system
Thickness gauge: Use online measuring equipment to monitor product thickness in real time, compare it with the set value, and adjust production parameters in time.
Automated control system: Use automated control system to automatically adjust extrusion parameters based on real-time data feedback to maintain product consistency.
5. Regular maintenance and calibration
Equipment maintenance: Regularly check and maintain extruders and related equipment to ensure their normal operation and avoid dimensional fluctuations caused by equipment failure.
Calibrating molds and measuring equipment: Regularly calibrate molds and measuring equipment to ensure their accuracy to maintain product quality.
6. Raw material characteristics
Selecting suitable raw materials: Different raw materials have different fluidity and cooling characteristics. Selecting suitable materials can improve the stability of the molding process and the final product.
Material pretreatment: Pretreatment of raw materials (such as drying, heating) can improve their fluidity, which helps control the thickness and width of the final product.
