Internal Mixer, Open Refining Machine.

Common Issues:

Uneven mixing, improper mixing temperature control, poor additive dispersion.

Process 3. Foaming & Molding

Key Processes:

Allowing the mixed materials to foam and expand under specific temperature and pressure, forming yoga mat blanks with desired density and thickness.

Main Equipment:

Plate Vulcanizing Machine, Foaming Oven.

Common Issues:

Process 4. Cooling & Shaping

Key Processes:

Cooling the foamed yoga mat blanks to stabilize and maintain their final shape.

Main Equipment:

Cooling Device.

Common Issues:

Uneven cooling, too fast/slow cooling, dimensional rebound/shrinkage.

Process 5. Cutting & Trimming

Key Processes:

Precisely cutting large yoga mat blanks into standard or custom sizes, and trimming edges to remove excess material, ensuring neat dimensions and appearance.

Misaligned/blurred printing, color inconsistency/chromatic aberration, poor adhesion/easy peeling, laser burn/damage.

Process 8. Quality Inspection

Key Processes:

Conducting rigorous quality inspections on finished yoga mats, including checks for dimensions, thickness, flatness, anti-slip properties, and appearance defects, to ensure compliance with all quality standards.

Main Equipment:

Measuring Tools, Visual Inspection Equipment.

Common Issues:

Missed defects, misjudgment, low inspection efficiency, inaccurate data recording.

Process 9. Packaging

Key Processes:

Cleaning and rolling qualified yoga mats, then performing inner packaging (e.g., OPP film) and outer packaging for transportation and sale.

Main Equipment:

Rolling Machine, Packaging Machine.

Common Issues:

Packaging damage, non-standard packaging, product contamination, loose/uneven rolling.
