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.
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
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.
