We develop and produce a product
which meets customer needs with our variety of persistence.
Design proposal based on both Ooka's forging technology and advantages will be provided from the initial design stage to customers.
Based on our long experience, our engineers provide the best design for products and tools.
Producing high precision forging tools by our experts in our completely clean plant where dust / vibration / temperature are severely controlled.
One of our most important process to have a base form of the product.
Latest hot forging press machine make sophisticated parts as if craftsperson's art.
Our latest Non-oxidized Isothermal Annealing Furnace enables an ideal metal structure and hardness. It adapts the automatic transfer robot system to avoid any damage on the parts.
Fully automated Cold forging line which is combined with shot blasting and lubricating device create a high accuracy products as well as machined parts.
Various machines such as 2-axis / 3-axis lathe turning, Broaching, machining, boring etc. enable to meet customer's requested.
Quenching with high / low temperature can be performed according to the product characteristic with 6-batch typed case hardening furnace.
For further high-accuracy, Gear honing, Grinding, hard turning can be done.
O-oka carries out not only in-process inspection, but also appearance check by skilled worker's eyes.
In addition, our thorough inspection system such as a latest CMM machine provides 100% quality assured parts to the customer.
