Nothing can be achieved in manufacturing work unless we acknowledge others. Even if what people conceptualize and want to build is a pipe dream, manufacturing starts from saying “there is potential” and “this can be built”. Without recognition it is impossible to think together with the customer.Progress cannot be made if it is decided from the outset that something is impossible. When a customer brings and explains a sketch, we proceed with the discussion as though the product is already halfway towards completion. I believe that the work of Taiseplas is to produce a way of working when it is apparent that the customer has an idea but does not know how to take that idea into mass production. Our thinking is always flexible and were are able to take action quickly. Taiseiplas will deliver manufacturing that contributes extensively to 21st century society, while building strong partnerships with all of our customers.
