Manufacturing Processes: Thermoforming vs. Blow Molding

When producing custom plastic trays, manufacturers typically choose between thermoforming and blow molding processes. Thermoforming involves heating plastic sheets and forming them over molds, making it ideal for shallow trays and packaging. Blow molding, Lekamachine’s specialty, creates hollow containers by inflating heated plastic into molds, perfect for more complex shapes.

“While thermoforming excels at rapid production of simple designs, blow molding offers superior strength and dimensional stability for custom plastic trays requiring complex geometries.”

Process Comparison for Custom Plastic Tray Production

Lekamachine’s advanced blow molding machines demonstrate how modern technology bridges these gaps, offering faster cycle times and reduced waste. Their single-stage stretch blow molding process combines injection and blowing for precision pharmaceutical and cosmetic trays that meet strict industry standards.

Innovations in rapid tooling have significantly reduced traditional lead times for both processes. This evolution allows manufacturers to respond quicker to market demands while maintaining quality. Companies can now prototype custom plastic trays in days rather than weeks, accelerating product development cycles.

Ultimately, the choice between thermoforming and blow molding depends on application requirements, production volume, and budget. While thermoforming suits high-volume, simple designs, blow molding delivers superior results for complex, durable trays. With experts like Lekamachine advancing blow molding technology, manufacturers gain more options for efficient, high-quality production.

Design Flexibility and Customization Options

Custom plastic trays offer remarkable design flexibility to meet diverse industry needs. From integrated dividers for medical instruments to stackable designs for retail displays, these trays can be precisely tailored. Lekamachine’s blow molding expertise enables complex geometries that traditional thermoforming cannot achieve, particularly for pharmaceutical and electronics applications where precision is make-or-break.

“The right customization transforms standard plastic trays into specialized solutions that enhance product protection, brand presentation, and operational efficiency.”
