Instant & Accurate Quotes

We will thoroughly review each drawing and provide accurate quotes.

We don't use online automated quotation tools, because it is very inaccurate. Online quote platforms rely solely on calculations based on cutting amounts and fixed coefficients, they fail to account for actual processing nuances, such as material deformation after heat treatment, tight tolerance requirements, grinding after heat treatment, etc. Consequently, automated price calculations can lead to inaccuracies, ultimately increasing your costs.

But you can rest assured at DEK!

Our quotations are both cost-effective and accurate because we have a team of professional mechanical engineers who meticulously review each drawing. These engineers boast over 10 years of experience and possess deep expertise in programming, machine operation, post-processing, material properties, and more.
