SENLAN Tools is a Dongguan-based custom injection mold manufacturer founded in 2012. Our main business is custom injection mold manufacturing for packaging, cap and closure, cosmetic packaging, medical consumable and precision molding applications. We also support custom non-standard mold components when required by the project, but we do not supply standard catalog mold parts.
With an in-house team of 80+ engineering and manufacturing staff, SENLAN Tools handles project review, machining, inspection and delivery internally. We focus on drawing accuracy, fit, surface quality, cavity-to-cavity consistency and long-run mold performance, helping customers build molds and mold components that assemble well and perform reliably in production.
Our advanced electrical discharge machining department is powered by a high-end fleet of 12 Sodick and 4 Makino EDM machines. Specializing in micro-tolerance manufacturing, we reliably achieve an ultra-precise accuracy of ±0.005mm.
Equipped with 4 Makino high-speed centers and 10 Jingdiao precision machines, our advanced CNC facility specializes in micro-tolerance manufacturing, guaranteeing flawless high-accuracy tooling components.
Equipped with 15 flat-surface grinders and 3 internal cylindrical grinding machines, our advanced facility specializes in micro-tolerance finishing. We guarantee perfect geometric tolerances down to 2 microns for custom tooling plates, core inserts, and high-precision guide components.
Equipped with 10 high-performance Hardinge CNC turning centers, our advanced facility specializes in micro-tolerance cylindrical manufacturing, guaranteeing flawless high-accuracy tooling components and circular mold inserts.
Equipped with 2 advanced ZEISS Coordinate Measuring Machines and 4 high-precision 2D optical projectors, our inspection facility conducts micro-level dimensional verification down to 0.005mm, guaranteeing perfect geometric accuracy for high-performance tool components.
Our mold assembly workshop supports complete custom injection mold projects, from core and cavity fitting to component assembly, inspection, and trial preparation. It helps ensure stable mold performance, smooth installation, and reliable delivery for packaging, closure, medical, and cosmetic applications.
