Sunbun injection molding machines with 140T-300T servo motor

We import SUNBUN injection molding machines from 1400 kN to 3000 kN directly from the manufacturer. Delivery time is approximately 3 months. A 180T injection molding machine is available for viewing at our office.

Sunbun is a leading manufacturer of servo injection molding machines with over 30 years of industry experience. It produces cost-effective injection molding machines for a variety of plastics processing applications.

SK series injection molding machines feature a mechanical, vertical, central clamping structure that provides 100% clamping force, 2%-6% material savings, and 10%-20% greater mold opening capacity than traditional machines. The finished product exhibits less warpage, earning it a favorable reputation among domestic and international customers.

Advantages:
• The use of hydraulic pumps with servo drives allowed for significant energy savings – up to 35% – compared to conventional drives
• Servo drives contribute to a longer life of the machine's hydraulic oil because it heats up less, and also to a lower noise level generated by the machine thanks to a lower average engine speed
• Production of injection molding machines in accordance with European standards, CE certificates

Injection system:
• Improved twin-cylinder, dual-extrusion injection design generates lower oil return back pressure during ejection, resulting in faster injection speeds and longer component life
• Double linear guide and double balanced displacement base can improve the accuracy of the machine barrel
• Precisely designed screw (made of 38/42 CrMoAl steel) significantly increases injection accuracy and effectively reduces the product defect rate
• Optional imported air nozzle with original packaging has flexible switch and reliable sealing
• A thick-walled cylinder and a high-power heater ensure high efficiency of plasticizing the material

Hydraulic system:
• The use of a high-quality, high-speed motor and hydraulic components ensures fast, efficient and long-lasting operation of the device
• Modular design of the high-response oil circulation system and hydraulic valve plate. The high-response oil circulation and moisture-free design effectively reduce pressure losses and accelerate system response.
• Original German oil lines and seals prevent oil leaks

Electronic control:
• The entire electronic control system has been designed for fully electric and high-speed injection molding machines
• It uses a modern control system, new hardware architecture, intelligent user interface and an efficient CPU processor ensuring high computing speed
• The use of EtherCAT/CAN All-Date communication technology guarantees a significant improvement in all technical parameters and more precise pressure and flow control
• The system has an Internet management function and displays energy consumption, which enables advanced modes of control and monitoring of the machine's operation

Clamping system:
• The SK series is characterized by an outward sliding mechanism and excellent construction, with quite a large space between the posts
• The very large mold opening stroke is 10–20% greater than in standard machines
• The mold mounting plate is made of QT500-7 ductile iron and is characterized by high strength and long service life
• Using high precision gear adjustment ring, large-scale transfer and compact structure to facilitate customer adjustment of mold thickness
