Chiba Dies Co., Ltd.

PR message

We are a gear manufacturer specializing in plastic and metal gears, prototyping, mold making, mass production, and testing. We have a tribology laboratory for plastic gears, and we can provide consistent support such as noise tests, durability tests, and material development support.

[GEAR+]
For resin gears, we have a solution site for solving all kinds of problems such as noise, durability, accuracy, etc.

[Speed Tri]
A best-in-class low-volume production service, Speed Tri enables prototyping and repeat molding using the same production methods as mass production, with gears delivered in as little as 3 days!

[CD Machining]
CD Machining is the process of drawing a long bar (2.5m) such as free-cutting steel, brass, or aluminum to form a finished product.
The accuracy is high, and you can expect a significant cost reduction for products that were previously processed by hobbing, milling, or wire processing.

[Rolling Worm]
We manufacture by cutting and increasing the surface roughness of the worm gear. Highly recommended as we receive requests from customers who prefer the surface roughness of the worm gear. The worm gears are mass-produced products with beautiful tooth surfaces. We successfully produce several million units per year.

[Hyper-lead Screw]
For those who consider weight reduction and fast movement, which were thought to be unachievable for conventional lead screws.

[Why choose Chiba Dies?]
Excerpts from surveys of our regular customers

>Company M, motor industry
We had been struggling for many years with noise reduction measures for our gear drive unit, but after we changed to the gears Chiba Dies suggested, it became so quiet that we could hear and see the difference. Moreover, as an amateur with limited knowledge of gears, I learned a lot from the tips you gave me on how to design gears that would be even quieter. I am looking forward to trying this technique in my next development project!

>Company K, E-bike industry
We had never molded gears in our company before, so we were very anxious at first. We started from zero in the selection of a molding machine, but thanks to Chiba Dies’ generous advice on professional knowledge and technology, and their constant follow-up, we were able to start mass production with peace of mind. We also received kind and detailed guidance on gear accuracy and were even taught a simple measurement method that we can use onsite, which will be very useful for quality control.
