At our trash can factory, we usually release new designs three to four times per year. Those major launches are planned around quarterly design windows, but we also make smaller updates more often—typically every six to eight weeks—when new colors, lid finishes, pedal systems, or liner options are ready. Spring often brings slim kitchen bins and recycling sorters, summer adds outdoor and commercial waste stations, autumn introduces sensor and touchless models, and winter focuses on heavy-duty industrial and hospitality bins. For OEM and ODM projects, the schedule is driven by the client: a custom trash can design can move from concept and 3D rendering to a functional sample in about 7–15 days, with production timing depending on mold and material requirements. We also keep an eye on market feedback, durability tests, and material innovations, so some designs are refreshed sooner if demand shifts. Wholesale buyers, retailers, and brand owners can request early access to prototypes or private catalogs. In short: expect 3–4 standard design releases each year, frequent micro-updates, and custom new designs whenever your project needs one.
