Product Description

SK SERIES MECHANICAL VERTICAL-COMPRESSION STRUCTURE

Resilient mould thickness and long displacement stroke

Reasonable oil circuit design, which is more energy-saving,
improves the operating speed and can save 2%-6% raw
materials from 90% products for the customers.

Reinforced molding board, thicker pull rod, high rigidity frame, with more stable operation state and longer service life.

TRADITIONAL STRUCTURE

The machine of this series is equipped with special high-speed storage motor and hydraulic components of world-renowned brands, to ensure a fast, efficient and prolonged operation. By applying high-response oil circuit and hydraulic valve plate with modular design, the machine has an optimized oil circuit layout large in size and free of damp, which can effectively reduce the loss of pressure.

Mechanical Vertical-Compression Structure Applied by Sunbun Injection Molding Machine

1.100% clamping use ratio, 10%-20% higher than that of traditional structures;
2. Less fins on the finished products;
3. 2%-6% raw materials saved from production than that of traditional structures;
4. Effective protection for the mould, molding board, and pull rod;
5. A opening stroke 10%-20% longer than that of traditional structures;
6. Less deformation caused by cooling of the products.
