1. Main body:
Spherical graphite iron FCD50 is age-passivated to have high tensile strength and toughness.
2. Hydraulic cylinder ram:
Made of high CR white cast iron and milled to a tolerance within 0.02mm.
3. Auxiliary hydraulic cylinder and hydraulic cylinder for loading/unloading the mold:
3-1. Hydraulic cylinder: adopting STKM-13 seamless steel cylinder and S45C precision machined piston.
3-2. Oil seals of hydraulic and auxiliary cylinder are adopting Japanese NOK oil seals.
3-3. Characteristics: durable, abrasion and temperature resistant.
4. Oil seal:
All shaft oil seals are packing and using Germany made UGD/J .
5. Vertical post:
Medium carbon steel is hard chromium treated to reach hardness HRC 55 to 58.
6. Rail for in/out molds:
The sliding plate surface is made of S45C, which is processed through ion-nitride, enables smooth sliding in/out molds and prolongs lifespan.
7. Working table (upper/lower plates):
Working table and mold in/out plates are ion-nitride, and milled to achieve hardness HRC-58.3-59.2. Both upper and lower plates are made of S50C.
8. Electrical heater:
Electrical heater uses nickel-chromium alloy with stainless copper cladding, temperature accuracy within ±3℃.
9. Hydraulic system:
The hydraulic system is controlled via proportional pressure and flow ratio with a collective circuit design. The ascending/descending speed of the main cylinder can be adjusted within the range of 20mm/sec to-136mm/sec.
10. Surface precision:
