PR message
Toyo Rikagaku Kenkyusho is a comprehensive manufacturer of metal processing that consistently produces various metal products from mold design to pressing, machining, welding, assembly, surface treatment, and finished products.
We have surface treatment facilities for stainless steel, titanium, and aluminum in our own factory, and the best feature is that we can perform "processing" and "surface treatment" in the same factory.
We can also handle assembly and sub-assembly at our own factory, and respond to customers' "collection needs".
By consolidating the content that multiple companies previously requested into one company, it is possible to reduce the management effort of the customer significantly.
Please entrust Toyo Rikagaku Kenkyusho with "package projects" including surface treatment and assembly.
【quality policy】
“We will devote ourselves to manufacturing that faces the direction of the customer.”
Satisfying the customer's required specifications, we quickly commercialize it at a reasonable cost.
In addition, we will continuously improve in order to respond to customer satisfaction.
