DLC Coating
The low friction coefficient of DLC coatings reduces resistance between surfaces, providing durability to components like tools and mechanical parts.
Instant & 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.

What is Injection Molding?
Injection molding is a manufacturing process used to create parts by injecting molten plastic into a mold. The mold is typically made from metal and designed to form the desired shape of the final product.
Once the plastic cools and solidifies, the mold opens, and the part is ejected. The process is fast, repeatable, and highly efficient for making large volumes of identical products. You start by choosing a suitable plastic, then the mold is closed, filled, cooled, and the part is released. If you need consistent, durable, and well-finished plastic parts with tight tolerances, injection molding is often the best solution to meet your production goals.
If you’ve moved past prototyping and are ready to scale your production, injection molding is likely the next step.
What are the Advantages of Injection Molding?
Injection molding offers reliable and efficient production with consistent quality, especially when you're creating parts in large volumes. It combines speed, precision, and material variety to deliver durable plastic components with clean finishes.
- Fast production cycles
- Consistent high-quality part
- Cost-effective production method
- Supports complex geometries
