The most used material is Alumina, and followed is Zirconia.
We have consistency produce process for alumina/ zirconia spare parts, it includes modeling CIP process,
sintering process, rough/ fine machining and packaging.
-Semiconductor, TFT/LCD parts
-Ceramic Vacuum Chuck
-Industrial customized products
Max product dimensions:
Round: ø600mm (material: alumina Al2O3)
Plate: 3500mm (material: alumina Al2O3)
The best accuracy of machining dimension is 0.001mm.
We could provide reverse-engineering service, making drawings according to samples, and go for further discussions.
STC have excellent reverse-engineering capability.
Customers could offer Shentin samples to do the reverse-engineering, make the 2D/3D drawing and process the part according it.
For example, if the customer needs to replace SST by ceramics, Shentin will evaluate the feasibility of the replacement and provide the best solutions.
Through product design and improvement, we will make the quality and life-time of spare parts better and longer.
Machine Equipment
STC have various machine equipment.
EX: CIP Equipment, Sintering Furnace, Tool Grinding Machine, Cylindrical grinding machine, Centerless Grinding Machine, Rotary grinding machine, Flat Grinding Machine and CNC/NC equipment. We will provide our best service and further applications for our clients.
