1. Metal Case:
Metal cases are typically crafted using processes such as stamping, welding, and coating. The production involves shaping iron sheets with molds, welding, and finishing the surface.
The primary material for metal cases is commonly using metal,alloys or stainless steel. This imparts durability and resistance to deformation.
Metal cases have a robust appearance, providing excellent protection against external impacts and pressure. They are suitable for protecting eyeglasses in harsh environments, and the metal material makes them easy to clean.
Foldable cases feature a collapsible design and are manufactured using processes like injection molding and folding assembly. Plastic materials, such as ABS and PP, are commonly used.
Cardboard is the predominant material for folding cases due to its lightweight and high pliability.
Foldable cases are portable and adjustable to accommodate different eyeglass sizes, making them convenient for everyday carry. The variety in plastic materials allows for diverse and personalized design options.
3. Soft Leather Case:
Soft leather eyeglass cases are typically assembled through sewing or adhesive processes, incorporating soft fabric enveloping an inner lining.
Common materials include velvet, nylon, PU, providing a soft and easy-to-process texture.
Soft leather cases are lightweight, easy to carry, and occupy minimal space. While providing basic protection, they are suitable for daily use.
4. Handmade Case:
Handcrafted cases involve manual processes such as cutting, sewing, and decorative detailing.
Handmade cases can use diverse materials like leather, fabric, or cardboard, depending on the artisan’s creativity and material choices.
Handmade cases are unique and exquisite, often possessing artistic qualities. They appeal to those seeking personalized and artisanal products.
5. EVA Case:
EVA cases are made from ethylene-vinyl acetate foam material, involving cutting with molds and heat pressing.
The primary material is EVA foam, providing a lightweight and somewhat flexible structure.
EVA cases are lightweight, offering excellent cushioning to protect eyeglasses from external shocks. They are suitable for scenarios where lightweight and shock resistance are crucial.
In summary, different eyeglass case types exhibit unique characteristics in craftsmanship, material composition, and advantages. Consumers can choose the most suitable type based on individual needs and preferences.
