The Plastic Button Back is a key structural component on the rear of anime badges (embellishments), providing a lightweight, robust, and insulated sealing solution. This product is manufactured using high-precision injection molding and is specifically designed to match standard tinplate covers, achieving a secure connection through snap-fit assembly or ultrasonic welding.
Its core value lies in reducing overall weight through a lightweight plastic structure, while completely eliminating the corrosion issues associated with metal back covers. It is especially suitable for high-quality badges that require long-term wear, frequent use, or weight-sensitive applications.
Core Materials and Processes
Material:
Plastic Button Back made from high-strength, high-toughness engineering plastics (such as ABS or PP), offering excellent impact resistance, dimensional stability, and environmental resistance. The material complies with environmental protection standards and is non-toxic and odorless.
Molding Process:
Precision molds are used for injection molding to ensure that internal structures of the bottom cover (such as slots and reinforcing ribs) are well-defined and accurate. The edges are smooth and free of burrs, and the fit with the top cover is tight and consistent.
Surface Treatment:
The standard model features a natural plastic texture with a smooth surface. A UV coating can also be applied upon request to enhance wear resistance and tactile feel.
Structural Design:
The inner walls are designed with scientifically distributed reinforcing ribs, effectively improving compressive strength and deformation resistance while maintaining a lightweight overall structure and protecting the built-in pin mechanism.

Core Product Advantages
Ultra-lightweight:
Compared with metal base covers, plastic significantly reduces the overall weight of the badge, improving user comfort. It is particularly suitable for large badges or clothing accessories.
Fully rust-proof and waterproof:
Plastic materials eliminate the risk of metal corrosion and offer inherent water- and moisture-resistant properties, making the badge more adaptable to various environments.
Excellent shock resistance and insulation:
The material provides good cushioning performance, protecting internal components during transportation and daily use. As an electrical insulator, it also offers enhanced safety.
Cost-effective and flexible design:
Injection molding supports mass production and high cost efficiency. Colors can be customized (such as black, white, or transparent), offering greater design flexibility.
Stable fit:
The professionally designed snap-fit structure ensures a secure and reliable connection when assembled with a matching tinplate cover, preventing accidental separation.
Typical Application Scenarios
Large badges and medals
The 150 mm diameter plastic base is ideal for producing lightweight large-format displays, medals, or decorative badges.
Everyday wearable badges
Standard sizes such as 58 mm are widely used for anime character badges and fan merchandise. Their lightweight design makes them suitable for long-term wear on backpacks or clothing.
Brand promotion and event gifts
Ideal for corporate promotional items or event souvenirs that require large-scale distribution, cost control, durability, and rust resistance.
Children's peripheral products
The lightweight, smooth-edged, and safe characteristics make these covers suitable for children's cultural and creative products.
