About Us
About SENLO
SENLO is a global provider and manufacturer specializing in engine and power model solutions.
Our strength lies in building a seamless supply chain and a diverse product ecosystem, all centered around model power. We are dedicated to making mechanical marvels accessible to everyone, enabling people of all ages to appreciate the beauty and joy of mechanical art. Through assembly, customization, and bringing models to life, we inspire creativity and help people discover the engineer within.
We currently operate four leading micro-engine model brands: RETROL,SEMTO, ENJOMOR, and HOWIN.
With our business expanding across North America, Europe, and Asia,we are proud to share the fascination of mechanical engineering with enthusiasts around the world.
What We Do
We design and produce fully operational engine models built with engineering-grade materials and real mechanical structures. Unlike decorative replicas, our models are designed to start, run, and demonstrate true power transmission and motion.
Our product range includes: Working steam engines、Stirling engines、Gasoline and diesel stationary engines、Assembly kits and finished display models.Each model is developed with a focus on structural accuracy, durability, and long-term performance.
Why We Build Working Engines
We believe that mechanical knowledge is best understood through motion.
Seeing a flywheel spin, a piston reciprocate, and power transfer through real components offers a level of understanding that static models cannot achieve.
At Senlo Models, we aim to preserve the beauty of classic engineering by transforming complex mechanical systems into accessible, tangible machines—built small, yet operating like the real thing.
Who Our Models Are Made For
Whether used for hands-on learning, demonstration, filming, or display, our models are built to perform.Senlo engine models are trusted and used by:
Engineering & Craftsmanship
From component design to final assembly, every step follows strict engineering and quality standards. Most components are machined from solid metal, carefully fitted and tested to ensure reliable operation.We place equal importance on:
- Mechanical accuracy
- Structural strength
- Surface finish and material quality
- Operational stability
