Quality Control Services
At KOYLU Makine, quality is not just a goal – it is our standard.
We combine decades of craftsmanship with modern CNC technology to produce mould accessories that meet the highest expectations of the glass industry. Our production facility is equipped with advanced CNC lathes, milling machines, and precision grinding systems to ensure consistent, reliable, and accurate results in every part we produce.
Each component—whether it's a Guide Ring, Baffle, or Blow Head—undergoes strict dimensional and surface quality controls. We work with top-grade stainless steel materials such as AISI 304, 321, 420, and 431, and apply vacuum heat treatment to achieve optimal hardness (35–38 HRC) where required.
But what truly sets us apart is our team. Our skilled technicians bring years of experience and attention to detail into every stage of production—from design to final inspection. This commitment to precision ensures the long-term performance and durability of each piece.
When you choose KOYLU Makine, you choose quality you can trust.
