Do lot production pieces differ from the samples?

From our experience, it often happens that lot production pieces are even better than the samples submitted for confirmation. It is because we start lot production from prepared measure gauges and jigs, which helps us achieve perfect dimensions and excellent appearance of the product.

Do you possess a stock of standard products?

We do not. The reason is that most of our production is made-to-order products. We are flexible and ready to adjust to our customers’demands, letting them choose desirable dimensions etc., therefore we don't limit our production to the stock of only standard products.

How would you respond if, by any chance, a TRA product did not fulfill the customer's
expectations?

In TRA we have developed the system of complete inspection of our products, but, if by any chance, the product is defective or unsatisfactory to our customer in some aspect, we would manufacture it again in the same factory in China or in another factory in Japan at our cost.
If the time needed for re-manufacture vastly exceeds the appointed date of delivery, we will send the products by air cargo or ship it by express vessel.
