With more than 50 years of production experience, DROUZHBA PLC offers the highest quality standard.
We manufacture pistons with diameter from 40 to 150 mm.
For casting we use mainly two methods:
• Gravity casting
SLF (Semi-Liquid Forging)
Gravity casting is made on 8 semi-automatic FATA machines.For SLF we use a 120 tons press.
For SSF we use a 120 tons press. The technology provides higher quality of the crystallized metal structure. It greatly improves the physical, mechanical and performance characteristics of the pistons.
For pistons machining we use a brand new sophisticated and modern CNC machinery line purchased from the Japanese leading manufacturer TAKISAWA.
