How to solve common problems in sealing strip forming equipment?

Sealing strip forming equipment often encounters some problems during use, such as leakage, breakage, and high scrap rate. The following will propose solutions to common problems and help solve the problem of sealing strip forming equipment.

1. Leakage problem: Leakage refers to the failure of raw materials to fully fill the mold, resulting in voids or cracks in the formed sealing strip. The methods to solve the problem of adhesive leakage include:

-Improving the flowability of the rubber material: The flowability of the rubber material can be improved by adjusting its formula or adding a flow agent, ensuring that the mold can be completely filled.

-Adjusting the molding parameters: The molding temperature and injection speed of the rubber can be appropriately increased to promote better filling of the rubber into the mold.

-Check mold design: Check whether the design of the mold is reasonable, such as whether the mold outlet is designed properly, and whether there are narrow areas that affect the entry of rubber into the mold.

2. Broken adhesive problem: Broken adhesive refers to the phenomenon that formed sealing strips are prone to fracture during use. The methods to solve the problem of adhesive breakage include:

-Adjusting the rubber formula: Adjust the rubber formula appropriately, select raw materials with good elasticity and wear resistance, and improve the durability of the sealing strip.

-Optimize mold design: Reasonably design the mold structure to minimize stress concentration and reduce the risk of fracture.

-Control the molding temperature: Both too high and too low molding temperatures can affect the performance of the sealing strip. The molding temperature should be controlled according to specific requirements to avoid aging and easy breakage of the adhesive caused by excessive temperature.

3. High scrap rate problem: High scrap rate refers to the occurrence of unqualified or substandard formed sealing strips during the production process, resulting in resource waste. The solutions to the problem of high scrap rates include:

-Optimize operation process: Train operators to improve their operational skills and standards, and reduce operational errors.

-Quality control testing: Establish a comprehensive quality control system, strengthen testing and monitoring of the production process, and promptly identify and solve problems.

-Regular maintenance: Regularly maintain equipment to ensure it is in good condition and reduce the occurrence of equipment failures and production accidents.

4. Poor appearance of the sealing strip: Bubbles, color differences, scratches, and other issues appear on the surface of the formed sealing strip, which affects the appearance quality of the product. The methods to solve the problem of poor appearance of sealing strips include:

-Improving the machining accuracy of molds: Improve the machining accuracy of molds, reduce surface defects of molds, and avoid adverse effects on the surface of sealing strips.

-Control the molding temperature: Improper molding temperature can cause problems such as bubbles on the surface of the sealing strip. Adjust the temperature according to the actual situation to achieve the appropriate molding temperature.

-Optimize mold surface treatment: Treat the mold surface, such as spraying mold lubricant or adding anti adhesive, to reduce the adhesion between the sealing strip and the mold and reduce the occurrence of adverse situations.

5. Low production efficiency: Low production efficiency refers to a situation where the production speed is slow and cannot meet demand. The methods to solve the problem of low production efficiency include:

-Technical improvement: Introduce advanced automation equipment to improve production efficiency. Adopting high-speed and stable equipment to improve production speed while ensuring yield.

-Process improvement: Analyze the production process, identify bottlenecks in production, and improve production efficiency by improving the process. The process can be optimized and adjusted to reduce tedious production operations and improve production efficiency.

-Strengthen personnel training: Train operators to improve work efficiency and reduce unnecessary human errors.

In short, solving common problems in sealing strip forming equipment requires comprehensive consideration from multiple aspects such as rubber formula, mold design, operation process, equipment maintenance, etc. By optimizing each link, production efficiency and product quality can be improved.
