From eco-friendly stainless steel materials to millimeter-level precision stamping, from the delicate touch of hand-polishing to the ingenious design of modular assembly, we adhere to near-exacting, transforming cold, hard metal into tangible art. Each product is a fusion of mechanical aesthetics and humanistic warmth, allowing users to experience the fun of mechanical principles during assembly and appreciate the charm of industrial design when displaying the finished piece.

★Perpetual Innovation

LONGPIN breaks the boundaries of traditional model products, pioneering a trinity experience of "Creation + Relaxation + Collection": the hardcore assembly challenge of mecha warriors, steampunk-style architectural miniatures, and mechanically dynamic display devices. Through continuously evolving original designs, we offer model enthusiasts, DIY lovers, collectors, and even professionals a deeply therapeutic experience that engages both hands and mind.

★Connected Co-Creation

We believe that every interlocking component sparks a collision of inspiration. Through open-ended DIY expansions, a global maker community ecosystem, and a "One-Product-One-Code" authentication system, LONGPIN is building a cross-age, cross-border alliance of creators. Where the cool gleam of metal meets the warmth of human ingenuity, the story of timeless value begins.


★The Spirit of Making

At the intersection of machinery and art, LONGPIN uses metal as its language to craft a modern legend of craftsmanship. We are not just manufacturers of parts but enablers of creativity—making every assembly a personalized expression and every piece a vessel for a unique story. it would be rendered naturally as "rigorous craftsmanship standards" or "exacting quality benchmarks" without annotation
