OEM LSR Injection Molding Silicone Reusable Collapsible Coffee Travel Cups Factory

Description:

LSR Injection Molding Silicone Reusable Collapsible Coffee Travel Cups are crafted using advanced Liquid Silicone Rubber (LSR) injection molding technology, offering durability, flexibility, and eco-friendly functionality. Made from high-quality, food-grade silicone, these cups are designed for optimal collapsibility and portability, making them perfect for on-the-go use. With certifications such as ISO9001 and FDA, our factory ensures the highest standards of quality and safety. As a leading manufacturer and supplier, we offer OEM and one-stop services, providing customized designs and efficient production to meet your business needs.

Characteristics:

Production Process:

1. Liquid Silicone Rubber (LSR) Formulation & Color Masterbatch Integration

– The FDA-compliant LSR base is precisely blended with Pantone-matched color masterbatches and platinum-based catalysts, ensuring optimal heat-activated curing.

2. High-Precision Mold Engineering

– Steel molds are CNC-machined with intricate spiral grooves and collapsible section geometries, incorporating cavities for in-mold logo embossing or In-Mold Labeling (IML).

3. Automated Liquid Injection Molding (LIM)

– LSR is injected into heated molds under 150-200 MPa pressure, where it cures at temperatures ranging from 160°C to 200°C. The seamless cup bodies, complete with embedded logos or patterns, are formed in just 30-90 seconds per cycle.

4. Post-Cure Demolding & Spiral Structure Calibration

– After mechanical demolding, the cups undergo secondary curing (2-4 hours at 120°C) to ensure stability of the collapsible spirals. Compression tests are performed to verify smooth telescoping functionality.

5. Surface Finishing & Logo Enhancement

– Multi-color logos are applied using laser engraving or pad printing, while food-grade coatings (e.g., non-slip grips) are added via spray-coating systems for enhanced usability.

6. Leakage & Durability Testing

– Automated pressure decay tests (up to 15 PSI) and rigorous 10,000-cycle foldability tests are conducted to ensure the cups meet industrial-grade performance standards.

7. Sterilization & Customized Packaging

– Prior to packaging, UV-C light sterilization is applied. The cups are then packaged in branded boxes or eco-friendly sleeves, with options for sustainable materials such as recycled PET or kraft paper.

Quality Assurance:

This process include material compliance with FDA standards for food-grade silicone, durability testing (e.g., repeated compression cycles, heat resistance for hot/cold beverages, and leak-proof performance under pressure), and structural validation of components like lids, seals, and collapsible mechanisms. Custom logo adherence is verified through abrasion resistance tests, colorfastness checks, and precision in application methods (e.g., laser engraving or embossing). Batch inspections cover dimensional accuracy, finish quality, and consistency in logo placement. Documentation such as Certificates of Analysis (CoA), compliance reports, and pre-shipment samples are provided to guarantee compliance with client specifications and industry regulations, while packaging is tested to prevent damage during transit.
