Injection detail1
We use a new generation of upgraded high-performance injection molding machines:
01-Opening Stroke
Increased by up to 15%
02-Ejector stroke
Increased by up to 20%
03-Mould thickness
Increased by up to 15%
04-Max. Daylight
Increased by up to 55%
05-Ejector Force
Increased by up to 40%
The injection molding machine uses Sellll upgraded components to achieve additional durability through an optimized clamping structure, a new and optimized injection unit design to meet various production needs, and uses an efficient and stable servo hydraulic system and high-performance European B&R control system.

01-30% higher energy saving than using traditional variable pump
02-Stable and smooth movement supported by AC servo motor
03-Effective reduction of energy consumption due to reduced oil and cooling water attained by hydraulic system
04-High performance European B&R control system
