Upon receiving factory-made glass bottles, customers may occasionally notice slight oil stains on the body or bottom. In this article, we explore the reasons behind these oil stains and offer preventive measures for customers.
Why Oil the Mold? In glass bottle production, molds on the production line are regularly oiled to facilitate smooth demolding of newly formed glass bottles. This practice ensures the quality of bottle molding, reduces wear on molds, and enhances production efficiency, ultimately minimizing production costs.
When oiling molds, it's crucial to use appropriate grease for different mold materials to prevent damage. Thoroughly cleaning oiling tools after use prevents mold contamination.
The frequency of oiling depends on mold usage, with too frequent oiling potentially leading to residual oil stains on the glass bottles.
Preventing Oil Stains:
a. Choose a Professional Glass Bottle Manufacturer: Opt for reputable manufacturers with skilled workers who follow precise oiling schedules. Professional production lines employ automated inspection equipment to detect and reject bottles with defects, ensuring that only flawless products reach customers.
b. Utilize Third-Party Inspection Companies: Consider hiring third-party inspection companies to assess each batch of goods before shipment. Look for companies with a broad service scope, cost-effectiveness, and a high level of professionalism in inspection services. This helps identify and address quality issues, reducing post-shipment risks.
c. Carefully Screen Suppliers: When sourcing glass packaging bottles for foreign trade, thoroughly vet suppliers beyond considering price factors. Verify their authenticity, reliability, product quality control, packaging strength for long-distance transportation, professionalism in service, and after-sales support. Trustworthy suppliers contribute to a smoother business relationship and minimize unexpected problems.
Understanding the causes of oil stains on glass bottles and implementing preventive measures is essential for both manufacturers and customers. By choosing reputable manufacturers, utilizing third-party inspection services, and carefully screening suppliers, customers can ensure the delivery of high-quality glass packaging products.
