Manufacture Process for GX40CrNiSi25-20 (EN 1.4848)
Our Services
- Sand Casting
Casting Quality focus on Metal Parts industry, we provide professional service in Metal Casting field.
Sand Casting is a popular metal form method, are suitable for all materiel, such as grey iron, ductile iron, malleable iron, carbon steel, stainless steel, aluminum and bronze.
- Investment Casting
Also named as precision lost wax casting, mainly suitalbe for carbon steel and stainless steel parts. We also provide grey iron and ductile iron and aluminum and bronze parts by investment casting. It can achieve the best appearance with good tolerance
- Shell Casting
Shell casting method is a good option to replace investment casting and sand casting. the quality is better than sand casting parts, suitable for bulk production.
- Permanent Mold Casting
For aluminum parts and Brozne parts
- CNC Machining
CNC Milling, CNC turning with 5 xix CNC center, we provide precision machining for all castings based on customers design drawings.
